Opis:
he Interatheriinae (Notoungulata, Interatheriidae) from the Collón Curá Formation (Colloncuran South American Land Mammal Age, SALMA) are revised here, based on old and new collections from western Neuquén, Río Negro, and Chubut provinces where this geologic unit crops out. After a detailed study of the holotype of Icochilus endiadys, we conclude that its cranial and dental morphology are diagnostic of the genus Protypotherium, and as a result we include I. endiadys in this genus (P. endiadys comb. nov.). Deciduous dentition and postcranial remains are also ascribed to P. endiadys, which allows us to determine its pattern of dental eruption and describe part of its limbs, expanding its diagnosis. In addition, we describe a new species of Protypotherium, P. colloncurensis sp. nov., which differs from P. endiadys in having larger size, a more robust mandible, strongly imbricate upper molars, a well-developed parastyle on P1, a subcircular and non-overlapping p1, a much reduced p2, and a smaller talonid on p3–4. Based on the revision, we identified only one genus of Interatheriinae in the Collón Curá Formation (i.e., Protypotherium). Protypotherium endiadys extends its distribution from Neuquén to Chubut provinces, including Río Negro; the new species, in turn, was only recognized in Río Negro Province, appearing together with P. endiadys in Estancia El Criado, Comallo, and Chico River localities. Discriminant and cladistic analyses were performed including P. endiadys, the new taxon, and other middle Miocene interatheres, and yielded strong support for our systematic conclusions. A thorough phylogenetic analysis of Protypotherium is provided for the first time. Based on this analysis, Protypotherium and Miocochilius form a monophyletic group supported by four synapomorphies.

Opis:
This article systematises procedures for dismissing a Head of State in the countries of South America. We look at the genesis of introducing impeachment to the constitutions of countries in this part of the world, paying close attention to the specific historical background of the Western Hemisphere, then focusing on the categorization and systematisation of the procedure itself. We present three models of the presidential impeachment in South America: Judicial, Bicameral and Unicameral. Using a contextual approach, doctrinal research, comparative method and theory-building strategy, we discuss the general features of these models and the specificities of use in each country of the continent.
Niniejszy artykuł podejmuje temat procedury odwołania głowy państwa w krajach Ameryki Południowej. Autorki przyglądają się genezie wprowadzenia impeachmentu do konstytucji państw leżących w tej części świata, zwracając uwagę na szczególne uwarunkowania historyczne zachodniej półkuli, a następnie skupiają się na kategoryzacji i systematyzacji samej procedury. W oparciu o kryterium dotyczące tego jakie ciało wnosi oskarżenie a jakie odpowiada za proces i decyzję o ewentualnym pozbawieniu urzędu, autorki wyróżniają trzy modele impeachmentu prezydenta w Ameryce Południowej: sądowniczy, dwuizbowy oraz jednoizbowy. Wykorzystując podejście kontekstualne, metodę dogmatyczno-prawną, metodę porównawczą oraz strategię budowania teorii, autorki omawiają ogólne cechy każdego z modeli, jak również jego specyfikę w krajach kontynentu.

The Chañares Formation exhibits one of the most important archosauriform records of early Carnian ecosystems. Here we present new data on the palaeohistology of Chañares archosauriforms and provide new insights into their paleobiology, as well as possible phylogenetically informative traits. Bone microstructure of Lagerpeton chanarensis and Tropidosuchus romeri is dominated by fibro-lamellar tissue and dense vascularization. On the other hand, Chanaresuchus bonapartei is more densely vascularized, but with cyclical growth characterized by alternate fibro-lamellar, parallel-fibered and lamellar-zonal tissues. Dense vascularization and fibro-lamellar tissue imply fast growth and high metabolic rates for all these taxa. These histological traits may be tentatively interpreted as a possible adaptative advantage in front of Chañares Formation environmental conditions.

The Uruguay River basin in South America has held a social, cultural, environmental, and economic relevance for many centuries. The river flows for about 2,000 km, linked to an important remnant of native forest, the Selva Misionera in Argentina, and to a Brazilian conservation unit for biodiversity, the Turvo State Park. The Uruguay River is fed by several other important rivers, forming a basin region in which thousands of people live and work. The history of the Uruguay River is intensively linked to the permeable borders between Brazil, Argentina, and Uruguay where different social groups circulated in diverse historical time periods. Forests along the river played a very important role with emphasis on the extraction and trade of yerba mate (Ilex paraguariensis, Saint-Hilaire), a forest product widely consumed in southern America, and also the timber extraction from native forests, during the nineteenth and twentieth centuries. As a result, a profound socio-environmental transformation took place with the reconstruction of regional landscapes shaped by the Uruguay River basin.

Opis:
This paper describes a petrified trunk collected from a conglomerate bed of the Springhill Formation (Berriasian– Valanginian) in the Estancia El Álamo locality, Santa Cruz Province, Argentina. The fossil trunk is classified within the ubiquitous genus Agathoxylon and the wood anatomy shows a close affinity to that of Araucariaceae. This Patagonian wood has a distinct combination of anatomical characteristics unique among all known species from the Jurassic and Cretaceous of Western Gondwana allowing to diagnose a new fossil taxon Agathoxylon mendezii sp. nov. Sedimentological and megafloristic proxies of the Springhill Formation suggest that Agathoxylon mendezii sp. nov. grew under a warm and wet climate, which indicates a subtropical to temperate palaeoenvironment. However, the large number of frost rings in the earlywood of this araucarian tree suggests that the palaeoenvironment at Estancia El Álamo was subjected to recurrent disturbances, most likely caused by regional continuous volcanic activity originating from volcanoes located far away to the west. This activity would have produced periodic stratospheric veils that promoted rapid decreases in surface air temperature; the wood response to such stressful conditions would have been the formation of numerous (at least five) frost rings. Although recurrent eruptions in Patagonia during the Early Cretaceous are well recorded, this study is the first to register eruptions recorded in a coniferous wood.

Illegal extraction of gold has grown to be a problem in many countries, causing the degradation of the environment. The main purpose of this paper is to investigate changes in tree cover and surface pollution. The development of a mine site has been observed and analysed with images acquired from Landsat and the Sentinel missions. The results of the study showed changes in the state of the environment, strongly suggesting the possibility of ongoing pyrite weathering processes and the transportation of clay materials down watercourses, which can cause not only the further deterioration of the environment but also slow down the natural regeneration of the forest. In addition, research has found disturbing changes in vegetation, showing a loss of tree cover in the Amazon Rainforest as high as 17%. The validity of using remote sensing methods to observe the development of individual mining sites and their characteristics was confirmed.

Opis:
The dental anatomy of Candelariodon barberenai from the Dino donto saurus Assemblage Zone (Pinheiros-Chiniquá Sequence, Santa Maria Supersequence, late Ladinian–early Carnian) of south Brazil, is redescribed. Candelariodon was originally classified as Eucynodontia incertae sedis and our analysis recovered this taxon deeply nested within Probainognathia, as the sister taxon of Potheriodon plus Prozostrodontia. The lower postcanine dentition of Candelariodon has several apomorphies shared with Prozostrodon, Santacruzgnathus, Brasilodon/Brasilitherium, and some basal mammaliaforms (Morganucodon, Megazostrodon), such as a lingual cingulum with discrete cusps e and g and two distinct morphologies in the tooth row. The reinterpretation of Candelariodon as a probainognatian cynodont more derived than Probainognathus and the rich Brazilian fossil record document an important adaptive radiation of non-mammaliaform prozostrodontians and closely related forms prior to the origin of the mammaliaform clade.

Opis:
Sections yielding late Maastrichtian ammonite assemblages are rare in Latin America and precise biostratigraphic correlation with European type sections remains difficult. In all, the extinction pattern of ammonites appears to differ between sites in southern high latitudes and those in the tropics to subtropics. In austral sections of Chile, and possibly also in southern Argentina, diverse assemblages range throughout most of the substage and then show a gradual decline prior to the Cretaceous–Paleogene (K–Pg) boundary. Further north, in northeast Brazil, only two genera (Diplomoceras, Pachydiscus) range into the uppermost Maastrichtian, but disappear within the last 0.3 Ma of the Cretaceous. In tropical sections of Columbia and Mexico, the decline of ammonites started earlier and Sphenodiscus is the last ammonite known to occur in the late Maastrichtian. In all sections revised here the disappearance of ammonites was completed prior to the end of the Maastrichtian and was thus independent of the asteroid impact at, or near, the end of the Cretaceous.

Opis:
In this paper, the highly peculiar masticatory apparatus of glyptodonts is studied. The general morphology of the skull is analysed using a morphometric procedure, the Resistant Fit Theta Rho Analysis, which allows comparison among different biological forms. Here, a large terminal form, the late Pleistocene genus Glyptodon, is compared with the smaller primitive Miocene genus Propalaehoplophorus, and with the generalised Recent armadillo Chaetophractus. The masticatory musculature of glyptodonts is reconstructed. Their tooth form and wear facets, as well as their mandibular symphysis and jaw joint, are analysed. A model of jaw movement is constructed based on these analyses. It is demonstrated that the masticatory apparatus of glyptodonts had undergone a telescoping process, which was already underway in the most ancient forms whose skull is known. This process created problems in regard to the way stresses produced by mastication were absorbed by the mandible, and therefore it might be regarded as non-adaptive. Some functional explanatory hypotheses are discussed, such as a requirement of keeping the moment of the weight of the cranium small enough to be counterbalanced by the neck muscles, or fitting the head into the armour.

Opis:
The study of Paleogene mammals of intermediate and low latitudes has increased in the last decades and has been clearly demonstrated their importance in the comprehension of the evolution and faunistic changes outside Patagonia. The study of these faunas permits establishing new comparisons among contemporaneous faunistic associations, completing the distributional patterns, and evaluating evolutionary changes in the lineages in relation to climatic conditions prevailing in each of the different regions. In this work we study the diversity of Dasypodidae recovered from the Geste Formation (Northwestern Argentina). Bearing levels of Geste Formation were referred alternatively to a Barrancan subage of Casamayoran SALMA (middle Eocene, Lutetian–Bartonian) or a Mustersan SALMA (middle–late Eocene, Bartonian–Priabonian) on faunistic comparations with their equivalent in Patagonia, although absolute isotopic data indicates ca. 37–35 Ma (late Eocene, Priabonian). We described the following taxa of Dasypodidae: (i) Dasypodinae Astegotheriini: cf. Astegotherium sp., ?Prostegotherium sp., Parastegosimpsonia cf. P. peruana; (ii) Dasypodinae indet.; (iii) Euphractinae Euphractini: Parutaetus punaensis sp. nov.; (iv) Dasypodidae incertae sedis: Pucatherium parvum, Punatherium catamarcensis gen. et sp. nov. In comparison with other beds bearing Eocene cingulate faunas from Northwestern Argentina, Geste Formation presents the greatest diversity of dasypodids. This association is consistent with a late Eocene age and shows a taxonomic and biogeographic relevant features given by a unique specific composition: (i) it differs from that known for contemporaneous faunas from Southern latitudes and younger associations from more tropical areas; (ii) it includes genera with close affinities to those distant areas; (iii) it presents unique taxa typical from Eocene units exposed at Northwestern Argentina. This highlights the evolutionary and biogeographic meaning of the cingulate of the Geste Formation and supports the idea that the faunistic regionalization probably obeyed to latitudinal than to temporal factors.

Opis:
The cursorial capability of the South American giant theropod Giganotosaurus carolinii should have been quite limited taking into account the strength indicator of its femur (approximately 7 GPa⁻¹) as well as the risk of experiencing grave or even lethal injuries involved in the falling of this multitonne animal on a run. However, even at low speeds a fall would have caused serious injuries. Thus, in accordance to the approach developed in this study, the maximum speed of Giganotosaurus should be not that which will implicate corporal lesions with minimum probability of lethalness. Instead, its maximum speed should be that which would permit the recovery of body equilibrium as each step is taken. Taking into consideration this approach, an indicator of stability is defined for bipedal, cursorial animals. This indicator is determined by the relationship between the time available for the movement of hip joint during the retraction of a hindlimb and the time needed to move the opposite hindlimb by an angle (in function of the speed) of sufficient magnitude as to facilitate the recovery of body equilibrium. This indicator was used to estimate the maximum speed of locomotion of Giganotosaurus (about 14 m s⁻¹) at which, from a kinematic point of view, the danger of falling does not exist.

Opis:
Distal femora of some extinct, endemic, South American herbivores are shown to have modifications related to knee extension. Toxodon (Order Notoungulata) had an enlarged medial trochlear ridge (MTR) similar to those seen in horses, The MTR of horses serves to 'lock' the patella and ligaments in the proximal position and it likely function the same for Toxodon. The patella of Toxodon has a medial process that would have locked by wrapping around the MTR. Macraucheniid and proterotheriid litopterns may also have had knee locks, but with a different mechanism. The femora of these litopterns have deep suprapatellar fossae in which the patellae could have become lodged. Indeed, the distal end of the patella of cf. Eoauchenia (Proterotheriidae) conforms to and is supported within the suprapatellar fossa. Several glyptodontids (Order Xenarthra) have conical MTRs that would have impeded the medial patellar ligaments during the initiation of extension. This would have caused patellar rotation and resulted in a complex knee extension. These glyptodonts also had suprapatellar fossae, suggesting that the ligaments slid over the MTR and 'locked' during hyperextension. Locking knees in these diverse animals implies that they stood for long periods of time and did not engage in intermittent, 'bout feeding' as seen in modern ruminants.

A total of 25 species of mollusks and crustaceans are reported from Oligocene seep deposits in the Talara Basin in northern Peru. Among these, 12 are identified to the species-level, including one new genus, six new species, and three new combinations. Pseudophopsis is introduced for medium-sized, elongate-oval kalenterid bivalves with a strong hinge plate and largely reduced hinge teeth, rough surface sculpture and lacking a pallial sinus. The new species include two bivalves, three gastropods, and one decapod crustacean: the protobranch bivalve Neilo altamirano and the vesicomyid bivalve Pleurophopsis talarensis; among the gastropods, the pyropeltid Pyropelta seca, the provannid Provanna pelada, and the hokkaidoconchid Ascheria salina; the new crustacean is the callianassid Eucalliax capsulasetaea. New combinations include the bivalves Conchocele tessaria, Lucinoma zapotalensis, and Pseudophopsis peruviana. Two species are shared with late Eocene to Oligocene seep faunas in Washington state, USA: Provanna antiqua and Colus sekiuensis; the Talara Basin fauna shares only genera, but no species with Oligocene seep fauna in other regions. Further noteworthy aspects of the molluscan fauna include the remarkable diversity of four limpet species, the oldest record of the cocculinid Coccopigya, and the youngest record of the largely seep-restricted genus Ascheria. Eucalliax is recorded for the first time from a seep and from the Oligocene.

Opis:
Notoungulates represent the most taxonomically diverse and temporally and geographically widespread group among South American native ungulates. Here, we analyze anatomical and systematic aspects of proximal tarsal bones recovered from the Lower and Upper Lumbrera formations (middle and late middle Eocene) in northwestern Argentina. We provide detailed descriptions, comparisons, and infer foot stances and range of movements for the taxa implicated. Material studied includes astragali belonging to the oldfieldthomasiid Colbertia lumbrerense (Lower Lumbrera Formation), a set of proximal tarsals referred as Typotheria indet. (Lower Lumbrera Formation), and tarsals (also including navicular and cuboid) of the informal taxon “Campanorco inauguralis” (Upper Lumbrera Formation). The comparison of the tarsals of Colbertia lumbrerense (middle Eocene of Argentina) with Colbertia magellanica (early Eocene of Brazil) reveals several differences including variations on the development and arrangement of articular facets, and the size of the dorsal astragalar foramen in the Argentinean species. The specimen of Typotheria indet. shows morphological affinities with basal interatheriid taxa. However, its larger size contrasting with the overall small body sizes of Eocene interatheriids precludes an indisputable taxonomic assignment. Concerning “Campanorco inauguralis”, our observations indicate that there is no morphological evidence for a close phylogenetic relationship with Mesotheriidae. It presents a “reversed alternating tarsus” condition, which is also observed in Leontiniidae, “Notohippidae”, Toxodontidae, and some typotherians. However, the spectrum of singularities exhibited by this form precludes the assessment of its relationships in the context of the Paleogene radiation of Typotheria and it is necessary to extend the comparison to Eocene notoungulates. Finally, in a morphofunctional context a plantigrade foot posture is inferred for the specimens here reported. These observations have the potential to provide functional proxies for paleoecological reconstructions to be applied to the study of the early radiation of these notoungulate faunas.

Opis:
Ornithosuchidae is one of the most enigmatic clades of Triassic pseudosuchians. The group is composed by three carnivorous species that were excavated from Upper Triassic beds of Scotland and Argentina. We describe the first ornithosuchid from the Upper Triassic sediments of Brazil and explore its phylogenetic affinities and implications for the evolution of the group. Dynamosuchus collisensis gen. et sp. nov. was found as the sister taxon of the Argentinean form Venaticosuchus rusconii. These relationships reject a potential endemic radiation of ornithosuchids from the Ischigualasto-Villa Unión Basin and would better support multiple diversification events. Our findings with ornithosuchids is consistent with the pattern reported for proterochampsid and erpetosuchid archosauriforms from Ischigualasto-Villa Unión and the Paraná basins. In addition, the presence of an ornithosuchid in the Late Triassic of Brazil suggests that ornithosuchids were more widespread than previously thought in the southern hemisphere. The new ornithosuchid further demonstrates a faunistic link between the Argentinean and Brazilian basins during the Carnian. Finally, the discovery of the new species provides the first clue of a putative necrophagous vertebrate from the oldest dinosaur-bearing beds and expands our knowledge regarding the trophic structure of the Late Triassic of Brazil.

Opis:
The form assumed contemporarily by spatial organization in South and Central America as a network of nodes and spatial linkages represents the outcome for the space of this region of long-acting external influences plus internal conditions that have - at diferent times in diferent ways shaped spatial relationships and the manner in which space in this part of the world is planned. Naturally, the spatial structure of today's economy is influenced further by globalization, with growing competition for access to resources, be these either mineral deposits or agricultural in nature. These impacts ensure that, notwithstanding the widely-voiced opinion on the need to protect nature in areas of the continent supporting moist tropical forests, and in the high Andes, the governments of the diferent countries continue to award concessions allowing corporations of global reach to exploit resources of value that are in demand worldwide. This aggressive “resources race” has its serious consequences with regard to the forms and scope the region's spatial management and organization assume. These processes ought to be regulated by spatial planning, which is thus failing to play its proper role at regional levels. Those researching South America refer without hesitation to the lack of planning and overexploitation of raw materials, with all the serious consequences this has for society, not least with regard to internal migration, expulsions, the impoverishment of groups in society deprived of their land, and so on.

Opis:
Ameryka Łacińska stała się celem masowej emigracji transatlantyckiej z Europy na przełomie XIX i XX w. Po przyjeździe na kontynent, przede wszystkim do Brazylii, Argentyny, Urugwaju, Paragwaju, imigranci, głównie z obszarów wiejskich Galicji, znaleźli się w odmiennym środowisku przyrodniczym, gospodarczo-społecznym, kulturowym i politycznym, co pogłębiało tęsknotę za krajem, krajobrazem swojej wsi i najbliższej okolicy. Asymilując się do nowych uwarunkowań czerpali wzorce z kraju ojczystego, podejmowali próby „oswojenia” najbliższej okolicy i starali się implementować rozwiązania znane ze starej ojczyzny. Przejawy takiej działalności uwidaczniają się silnie w krajobrazie, w którym zidentyfikowano wyróżniki o charakterze przyrodniczym i kulturowym oraz materialnym i niematerialnym. Kolejne pokolenia podtrzymywały tradycje przodków, nie tylko jako przejaw tęsknoty za krajobrazem z Europy, ale również w celu zademonstrowania pochodzenia i podkreślenia odmienności od pozostałych osadników.
Latin America became the destination of massive transatlantic emigration at the turn of the 19th and 20th century. After reaching the continent, mostly Brazil, Argentina, Uruguay and Paraguay, the emigrants – originated from the rural areas of Galicia, found themselves in a different natural, as well as economic, social, political and cultural environment, which increased their nostalgia for the homeland and the landscape of the familiar countryside. While assimilating to the new conditions, they applied patterns familiar from the country of their origin, thus trying to "domesticate" the neighbourhood, attempted to implement solutions known from their previous homeland. Examples of their activities are clearly visible in the landscape, in which certain discriminants were identified, both showing natural and cultural, material and intangible characteristics. The following generations maintained the tradition of their ancestors not only as the manifestation of their nostalgia for the European landscape, but also to demonstrate their origin and underline their distinctiveness from other settlers.

Opis:
Structures discovered near Mar del Plata are attributed to palaeoburrows built by fossil animals on the basis of morphological patterns, transgressive boundaries in relation to the sedimentary units, and the presence of claw marks on the walls and roofs. They are discrete features of several metres in length, and with subrounded cross sections. Their diameters range from 0.80 to 1.80 m, with the width generally exceeding the height. These structures occur in Pleistocene deposits containing mammals referable to the Ensenadan and Lujanian Ages. Several Xenarthra are good candidates as builders of these burrows. Palaeoburrows were attributed before to the large Pleistocene armadillos Propraopus, Eutatus, and Pampatherium. We consider the possibility that the mylodontid ground sloths were responsible for excavating the burrows. The similar diameters of the burrows and the sloths are consistent with this observation. Anatomical, allometric, and biomechanical analysis of sloths limbs indicates that they were well designed to perfonn such activity. The shape of some claw marks preserved on the sides and roof of the burrows fits the form of their hand skeleton. Thus, the mylodontid sloths Scelidotherium and Glossotherium are considered as possible builders for the large late Cenozoic burrows present in the Pampean region.

Opis:
Bromeliothrix metopoides was discovered in tank bromeliads from Central and South America. Pure cultures could be established in various media stimulating growth of its food, i.e. bacteria and heterotrophic flagellates of the genus Polytomella. The new ciliate was investigated in the light- and scanning electron microscope, with various silver impregnation techniques, and with molecular methods, using the small-subunit rDNA. The morphology and its changes during the life cycle are documented by 167 figures and a detailed morphometry. Bromeliothrix metopoides is about 27–55 × 22–36 μm in size and has a complex life cycle with Metopus-shaped, bacteriophagous theronts and trophonts (microstomes) and obovate, flagellate-feeding macrostomes having a large, triangular oral apparatus. The thin-walled resting cysts of the theronts and trophonts are uniquely ellipsoidal, while the thick-walled cyst of the macrostome morph is globular. Reproduction occurs in freely motile condition either by binary fission or polytomy, producing a unique, motile “division chain” composed of four globular offspring, of which the central ones are connected by a curious, plug-like holdfast. Division is associated with a complete reorganization of the parental oral and somatic infraciliature. Stomatogenesis is merotelokinetal as in other members of the order Colpodida. The right polykinetid is generated by the rightmost postoral kinety, while the left polykinetid is produced by the two left postoral kineties and five left side kineties. The division in freely motile condition resembles the Exocolpodidae Foissner et al., 2002, to which Bromeliothrix is tentatively assigned, differing from Exocolpoda mainly by the formation of a macrostome morph and a division chain. Bromeliothrix has a ciliary and silverline pattern typical for members of the family Colpodidae. This matches the molecular classification which, however, hardly reflects the outstanding division and life cycle, suggesting some decoupling of morphological and molecular evolution. The specific morphological and ontogenetic traits of Bromeliothrix are interpreted as adaptations to the highly competitive habitat, favouring r-selected life strategies. Bromeliothrix metopoides is widespread in various tank bromeliads and can be easily cultivated in a wide variety of limnetic and terrestrial media. Thus, it remains obscure why this ciliate is restricted to tank bromeliads, i.e. did not occur in about 2,000 soil and freshwater samples investigated globally, including some 100 samples from Central and South America.

Opis:
Presence-absence bivalve species data for each Early Jurassic stage along southeastern South America between 20 and 46°S present-day latitude were processed by a set of analytical methods to analyse the palaeolatitudinal patterns of diversity and distribution. The expected decrease in species diversity towards higher latitudes is punctuated by a consistent local diversity increase between 34 and 42°, especially evident during Pliensbachian and Toarcian times, which may be due to an abrupt change in palaeogeography at that latitude, coinciding with the Curicó direct connection to the open ocean and the establishment of an increased variety of habitats within the extensive Neuquén Basin. The proportions of systematic groups show relative increases towards both higher latitudes (Crassatelloidea, Nuculanoidea, Pectinoidea, Monotoidea, Inoceramoidea) and lower latitudes (Trigonioidea, Pholadomyoidea, Limoidea, Lucinoidea). Epifaunal bivalves were dominant during the Hettangian but by Pliensbachian–Toarcian times they were less common than infaunal ones, while semi-infaunal species had low diversities during the whole Early Jurassic. This study suggests that (a) large scale geographical conditions should be taken into account for the analysis of latitudinal diversity trends among benthonic faunas; and (b) latitudinal trends of some living bivalve lineages may have a longer and more complex history than previously thought.

Opis:
A redescription of the extinct snake genus Colombophis is presented, on the basis of new specimens from the late Miocene of southwestern Brazilian Amazonia, and those previously reported for the middle Miocene of Colombia and Venezuela. The reappraisal of Colombophis allows the recognition of a new species,C. spinosussp. nov. The revised diagnosis of the genus is based on the midtrunk vertebrae, distinct from those of other snakes mainly in the features of the neural arch, position and shape of the neural spine, inclination of the zygapophyses, shape of the centrum, and development of the haemal keel. The affinities of Colombophis with “Anilioidea” are still unresolved; it is distinguished from all known extinct and extant “anilioids” due to its great vertebral size and the frequent presence of paracotylar foramina. The posterior paired apophyses of the haemal keel in some vertebrae, and the high neural spine of C. spinosus also contrast significantly with the “anilioid” genera, making the allocation of the genus into this probably paraphyletic group not well supported. Here, we recognized Colombophis as a basal alethinophidian of uncertain relationships.

Opis:
We investigate for the first time the species composition and community structure of lobose thecamoebians (Arcellinida) inhabiting an unpopulated and pristine island from the southeastern Pacific. Results revealed low alpha diversity and a high proportion of cosmopolitan species. One genus, four species and two subspecies were identified for the first time for southwestern South America. Further, four morphotypes were not identifi ed to species level, and one could not be identifi ed to species or genera level. They are probably endemics of this poorly studied and remote zone. These results were consistent with the moderate endemicity hypothesis of microbial biogeography. We hypothesized that the low diversity of species recorded on the island is due to selective colonization-extinction dynamics, processes that determines the low species richness of insular macro-organisms. However, this hypothesis needs to be evaluated in the future. Statistical analysis showed that testate amoebae were distributed in two discrete communities in the island. The first consisted of organisms inhabiting habitats located within a forest and the second by organisms inhabiting habitats located outside the forest. The suggested primary factor differentiating these both communities was the availability of appropriate habitat for the different species of testate amoebae.

Kraje Ameryki Południowej przeszły w ostatniej dekadzie XX w. proces dezinflacji i budowy zaufania do własnych walut. Większość z nich przyjęła strategię celu inflacyjnego. Gospodarka kontynentu jest włączona w procesy globalizacji przez eksport surowców i żywności, a także przepływy kapitału, co sprawia, że poziomy inflacji i stóp procentowych są determinowane nie tylko przez czynniki wewnętrzne. Celem badania jest uzyskanie odpowiedzi na pytanie, czy decyzje dotyczące stóp procentowych w politykach monetarnych krajów Ameryki Południowej są powiązane z polityką pieniężną kluczowych gospodarek spoza regionu, jak również, czy daje się zauważyć ich wspólny trend w ramach kontynentu.
During the last decade of the 20th century South America countries underwent the process of disinflation and reestablishment of confidence in their own currencies. Most of them adopted the strategy of inflation target. The economy of the continent is involved in the globalization processes through export of raw materials and food, as well as through capital flows what determines the fact that the inflation and interest rates are shaped not only by the internal factors. The purpose of the research is to answer the question whether the decisions concerning the interest rates in the monetary policies of the South America countries are connected with the monetary policy of key economies from outside of the region and also if it is possible to observe a common trend within the continent.

With the view to the strategic importance of the cooperation between American states, the author presents how the North American Free Trade Agreement functions and describes the process of founding the Free Trade Area of the Americas (FTAA). The first part of the article devoted to the NAFTA looks at the main principles of the Area as well as at trends in trade among its members. In the second part dealing with the FTAA the author presents the main reasons for the commencement of negotiations regarding the foundation of the FTAA and synthetically presents its economic potential.

Fossil remains of South American tapirs are often fragmentary and scarce compared with those of other mammals that entered South America during the “Great American Biotic Interchange”. Here, we review and add to the Pleistocene tapir remains from the Tarija Valley (Bolivia), and provide a taxonomic re-evaluation of Tapirus tarijensis. T. tarijensis was a large-sized animal, approximating the size of the living Malaysian T. indicus and the extinct North American T. haysii. The geographical distribution of Pleistocene records of Tapirus in South America indicates that T. tarijensis was the only known species inhabiting the Tarija Valley during this time.

Opis:
Przedmiotem pracy jest analiza procesów integracji gospodarczej w Ameryce Południowej. Celem przeprowadzonych badań jest próba dokonania oceny, w jakim stopniu utworzenie ugrupowania Sojuszu Pacyfiku może wpłynąć na kształt procesów integracyjnych na tym kontynencie oraz stanowić alternatywę dla istniejących już ugrupowań, w szczególności największego ugrupowania integracyjnego w Ameryce Południowej, którym jest Wspólny Rynek Południa (Mercosur). W pracy przeprowadzono analizę porównawczą modelu integracji oraz polityki gospodarczej państw tworzących Sojusz Pacyfiku oraz Mercosur, a także analizę danych jakościowych i ilościowych w stosunku do wskaźników ekonomicznych badanych państw. Na bazie przeprowadzonej analizy, wykazane zostały zależności między polityką gospodarczą oraz poziomem rozwoju gospodarczego analizowanych państw, ocen w zakresie konkurencyjności gospodarek oraz stanu wolności gospodarczej. Przeprowadzone badania wykazały, że wspólną cechą polityki gospodarczej państw Sojuszu Pacyfiku jest stosunkowo duże, w porównaniu z innymi państwami regionu, otwarcie na zewnętrzną konkurencję oraz instytucjonalizacja współpracy gospodarczej z państwami wysoko rozwiniętymi. Badania wykazały ponadto, że zastosowana przez te państwa polityka gospodarcza oraz otwarty model integracji gospodarczej miały pozytywny wpływ na ich rozwój gospodarczy, wysokość wymiany handlowej oraz poziom napływu inwestycji zagranicznych.
The subject matter of the study is an analysis of the processes of economic integration in South America. The aim of the carried out research is an attempt to assess to what degree the setting up the Pacific Alliance formation may affect the shape of the integration processes on this continent and be an alternative for the already existing formations, particularly the biggest integration bloc in South America, i.e. the Southern Common Market (Mercosur). In his study, the author carried out a comparative analysis of the model of integration and the economic policy of the states forming the Pacific Alliance and Mercosur, as well as an analysis of quantitative and qualitative data related to the economic indicators of the states in question. Based on the carried out analysis, the author pointed out to the relationships between the economic policy and the level of economic development of the states being analysed, evaluations related to competitiveness of economies and the condition of economic freedom. The carried out research have demonstrated that the common feature of the economic policy of the Pacific Alliance member states is a relatively large, compared to other states of the region, openness to external competition and institutionalisation of economic cooperation with economically advanced states. The research also have shown that the economic policy applied by these states and the open model of economic integration have had a positive impact on their economic development, volume of trade, and the level of foreign investment inflow.

Pomimo kryzysu, w którym się znajduje, Wenezuela jest niezwykle istotnym państwem zarówno dla Ameryki Łacińskiej jak i całego świata. Kraj z obszernymi złożami ropy naftowej i innych cennych surowców stara się pokonać wewnętrzny kryzys. Sytuacji nie ułatwia niestabilna sytuacja polityczna, nieustępliwość reżimu Nicolasa Maduro i ciągle walcząca o władzę opozycja. Lista zarówno przyczyn jak i skutków, jakie niesie za sobą sytuacja w Wenezueli jest długa. Niestety nie można powiedzieć tego samego o koncepcjach rozwiązania problemu w skuteczny i zadowalający każdą ze stron sposób.
Despite the crisis in which it finds itself, Venezuela is an extremely important country both for Latin America and the whole world. A country with vast deposits of oil and other valuable resources is trying to overcome an internal crisis. The situation is not made easier by the unstable political situation, the tenacity of the Nicolas Maduro regime and the opposition constantly fighting for power. The list of both causes and consequences of the situation in Venezuela is long. Unfortunately the same cannot be said about the concepts of solving the problem in an effective and satisfactory way for each side.

Opis:
The fossil record of temnospondyls in South America has been greatly expanded in the last 10 years, increasing their overall significance. They occur in Argentina, Brazil, and Uruguay, and range from the Guadalupian to the Late Triassic. The Early Triassic temnospondyl record in southern Brazil is mainly composed of fragmentary specimens, usually represented by dermal skull bones from the Sanga do Cabral Formation. Some of these fragments were tentatively referred to Lydekkerinidae and Rhytidosteidae based on their characteristic ridge−grooved “spider−web” pattern of ornamentation. In this contribution we report, for the first time, a temnospondyl skull fragment with pustulated sculpturing pattern, which is tentatively ascribed to Plagiosauridae. This new record could indicate the presence of a new temnospondyl taxon for the Lower Triassic of South America.

General remarks on the invasiveness of the species and on the possibility of finding it in other parts of the world are given. The distribution of the species world-wide requires further studies, since the bulbous rush has become an invasive plant in areas where it did not occur before.

Opis:
The article investigates the everyday life and festivity of the Polish community living in Itapúa department in Paraguay. The research also addresses the sense of national identity of the descendants of Poles who came to Paraguay in the years 1936-1938. It firstly presents the socioeconomic conditions of the districts of Itapúa, Carmen del Paraná and Fram, where field-work was carried out. Due to the agricultural nature of the Poles’ emigration to Paraguay, the research was conducted mainly in a rural environment where agriculture and small entrepreneurship are the primary occupations. The research was based on two types of sources: induced (open interviews) and existing ones. Eighteen in-depth interviews were conducted with representatives of the first and second generation born in Paraguay, giving a picture of the life of four generations. The elements of everyday life and festivity presented in the article are the most widely discussed aspects of the life of the Polish community in the context of maintaining the national identity of successive generations of Polish emigres. The key concept of the analysis is family. The research concludes that changes in family structure initiate alterations in the self-definition of members of the Polish community.
El artículo presenta la vida cotidiana y, a la vez, la festividad de la sociedad polaca que habita las tierras de Itapúa en Paraguay. El texto trata sobre las cuestiones relacionadas con la conciencia de la identidad nacional de los descendientes de los polacos que habían llegado a Paraguay en los años 1936-1938. Por otra parte, son presentadas las circunstancias socioec-onómicas del distrito del departamento Itapúa: Carmen del Paraná y Fram en las que fueron realizadas las investigaciones de campo. Debido al carácter agrario de la emigración de los polacos en Paraguay, las investigaciones se llevaron a cabo principalmente en el ámbito rural en el que la principal ocupación es la agricultura y pequeñas empresas. Las investigaciones fueron basadas en dos tipos de fuentes: fuentes primarias (entrevista libre) y fuentes secundarias. Se realizaron 18 entrevistas en profundidad con los representantes de primera y segunda generación de los descendientes de inmigrantes polacos, en las que se consiguieron las imágenes de cuatro generaciones. Los elementos de la cotidianidad y la festividad, presentados en el artículo fueron debatidos por los encuestados en la forma más amplia, como el aspecto de la vida diaria de la comunidad polaca en el contexto del mantenimiento de la identidad nacional a través de varias generaciones de los inmigrantes polacos. En el análisis, el concepto clave es la familia. Las investigaciones muestran que las transformaciones que se producen en la estructura familiar, influyen profundamente en el cambio de manera de definirse de los miembros de la comunidad polaca.

Opis:
We describe a Cretaceous ?cimolodontan multituberculate p4 from South America, for which we erect the new genus and species Argentodites coloniensis. This new taxon is represented by an isolated ?left p4 from the Upper Cretaceous (?Campanian or Maastrichtian) La Colonia Formation of Patagonia (Fig. 1). It has a strongly convex anterior margin and prismatic enamel, which attest to its cimolodontan nature, while the previously known p4 (MACN−RN 975) from the Late Cretaceous Los Alamitos Formation is roughly rectangular, suggesting “plagiaulacidan” affinity. The presence of normal prismatic enamel in Argentodites suggests similarities to Ptilodontoidea. However, it differs from the Late Cretaceous and Paleocene Laurasian cimolodontans (including Ptilodontoidea) in having a long, straight posterior margin, a nearly straight dorsal margin, characteristic of some “Plagiaulacida”, and in having the lingual side close to the mirror image of the labial side, the character that poses difficulties in establishing whether it is a right or left tooth. Because of these differences we assign Argentodites to ?Cimolodonta, tentatively only, superfamily and family incertae sedis.

Opis:
The paleoecology of the South American fossil carnivores has not been as well studied as that of their northern relatives. One decade ago Fariña suggested that the fauna of Río Luján locality (Argentina, late Pleistocene–early Holocene) is not balanced because the metabolic requirements of the large carnivores are exceeded by the densities and biomass of the large herbivores. This conclusion is based on the calculation of densities using allometric functions between body mass and population abundance, and is a consequence of low carnivore richness versus high herbivore richness. In this paper we review the carnivore richness in the Lujanian of the Pampean Region, describe the paleoecology of these species including their probable prey choices, and review the available information on taphonomy, carnivore ecology, and macroecology to test the hypothesis of “imbalance” of the Río Luján fauna. The carnivore richness of the Río Luján fauna comprises five species: Smilodon populator, Panthera onca, Puma concolor, Arctotherium tarijense, and Dusicyon avus. Two other species are added when the whole Lujanian of the Buenos Aires province is included: Arctotherium bonariense and Canis nehringi. With the exception of D. avus and Arctotherium, these are hypercarnivores that could prey on large mammals (100–500 kg) and juveniles of megamammals (>1000 kg). S. populator could also hunt larger prey with body mass between 1000 and 2000 kg. The review of the “imbalance” hypothesis reveals contrary evidence and allows the proposal of alternative hypotheses. If high herbivore biomass occurred during the Lujanian, a higher density of carnivores could be supported than as inferred from the power function of body size and population density.

Este documento contiene una investigación que presenta resultados asociados con las actitudes de los estudiantes suramericanos hacia compañeros extranjeros, presentando datos informativos en relación a xenofobia, inmigración y educación. La población estuvo compuesta por estudiantes activos de educación secundaria de 6 ciudades representativas de países suramericanos (Buenos Aires Argentina, São Paulo Brasil, Santiago de Chile, Bogotá Colombia, Guayaquil Ecuador y Lima Perú) y una muestra de 1440 estudiantes (240 por país) con edades comprendidas entre los 12 y 17 años de edad. Se aplicó de manera asincrónica un instrumento llamado “Test de Percepción Sociocultural” contentivo de 20 ítems presentados en una escala Likert agrupados en ítems de valoración positiva y valoración negativa. Los datos se procesaron con el Paquete Estadístico para las ciencias sociales (SPSS). Los resultados demuestran que en la mayoría de los países suramericanos existen entre la población escolar joven actitudes xenófobas hacia los inmigrantes suramericanos. Los resultados demuestran que en la mayoría de los países suramericanos participantes hay un grado de percepción positiva hacia los inmigrantes por parte de la población escolar joven, sin embargo hay casos puntales en los que se observa un grado de rechazo hacia los extranjeros.
This document contains an investigation that presents results associated with the attitudes of South American students towards foreign colleagues, presenting informative data in relation to xenophobia, immigration and education. The population was structured by active high school students from 6 representative cities of South American countries (Buenos Aires Argentina, São Paulo Brazil, Santiago de Chile, Bogotá Colombia, Guayaquil Ecuador and Lima Peru) and a sample of 1440 students (240 per country) with ages between 12 and 17 years of age. An instrument called "Sociocultural Perception Test" was applied asynchronously, containing 20 items presented on a Likert scale grouped into positive and negative assessment items. The data were processed with the Statistical Package for the social sciences (SPSS). The results show that in most of the participating South American countries, there is a degree of positive acceptance of immigrants by the young school population; however, there are key cases in which a degree of rejection of foreigners is observed.

Kolejna edycja prezentowanego cyklu, dotyczącego elitarnej komunikacji kolejowej, odnosi się do, rejonu Ameryki Środkowej i Południowej. W publikacji przedstawiono historię i uwarunkowania rozwoju szlaków oraz charakterystykę poruszających się po nich bardziej znaczących pociągów. Analizą objęto zarówno aspekty techniczne, jak i jakość świadczonych usług oraz szeroki zakres związanych z podróżą doznań turystycznych. W przeprowadzonych rozważaniach wykazano specyfikę i odrębność cech, związanych z transportem kolejowym wybranych państw. Wskazano na przyczyny i skutki sprawiające, że w tym regionie świata zanotowano najgłębszy regres w świadczeniu usług kolejowych, a jego pasażerska komunikacja ustępuje transportowi kołowemu i lotniczemu. Nawiązując do myśli przewodniej całego cyklu zaprezentowano najciekawsze pociągi, wyróżniające się wyższym poziomem komfortu, obsługi pasażera, wykazujące równocześnie, że także w państwach mniej zamożnych istnieje zapotrzebowanie na elitarne usługi kolejowe.
The next edition of the presented series for elite railway communication refers to the region of Central and South America. The publication presents the history, development conditions of routes and characteristics of the more significant trains which run on them. The analysis included both the technical aspects, the quality of services and also a wide range of travel-related tourist experience. Conducted considerations demonstrated the specificity and auton¬omy features associated with rail of selected countries. The causes and effects which provoked the deepest recorded regression in the provision of rail services in this region were pointed out as well as why passenger transport in the region gives way to vehicular and air transport. Referring to the keynote of the whole series the most interesting trains were presented. Distinguished by a higher level of comfort, passenger service, at the same time demonstrating that even in poorer countries there is a demand for elite railway services.

Opis:
The present study examines the research output and citation analysis in the field of Oncology, a branch of medical science which deals with the study and treatment of tumours, what we commonly know as cancer. Cancer as a disease is not confined to a particular region or a country, but is a global phenomenon and is still beyond the complete understanding and control of medicos. Research in the field of biomedical sciences in general and oncology is particular is undertaken at global level with almost each country contributing its bit in understating and control of disease. The study makes an empirical assessment of the research output and growth in the field of oncology at continental level for the period 2003-2012 and evaluates the aspects like research growth, citation analysis, h-Index etc. Data for the present study has been retrieved from the SCImago Journal and Country Ranking, which is totally based on the SCOPUS data source. Findings: - A total of 310593 research papers were published across six continents of the world during the period 2003-2012. Europe emerged the largest continent with its publication share of (124598, 40.11 %). Europe is followed by North America with its share percentage of (102897, 33.12 %) and Asia with (70555, 22.71 %). The contribution of Oceania, South America & Africa to the world oncology research is not that encouraging, as such there is greater need to promote oncology research in these continents. African contribution to global oncology research during the period remained (2215, 0.71 %), South American (3009, 0.96 %) and Oceania contributed (7319, 2.35 %). Oncology research publication on average during the period of study grew annually at 8.15 %, while as at continental level Africa registered highest annual publication growth of 19.08 %. North America and Europe are the only continents which recorded publication's growth below the average global growth.

El objetivo del artículo es dar cuenta de unas características de las lenguas amerindias subyacentes a ciertos cambios morfosintácticos y lexicales del español, tales como la manera de jerarquizar y de lexicalizar los conceptos de aspecto y de dinamicidad, las cuales diferencian estos idiomas del castellano. El artículo demuestra que dichas diferencias, resultado de conceptualizaciones del mundo (Lozada Pereira, 2006) y de la temporalidad (Evans, 2007; Wilk-Racięska, 2007) divergentes, revisten particular importancia tanto en las investigaciones de las lenguas amerindias como en estudios de algunos cambios en español debidos a estas lenguas.
The aim of the article is to draw attention to some of the features of Amerindian languages underlying several morphosyntactic transformations in South American Spanish, which cause it to significantly differ from Spanish. The focus is on the hierarchy and lexicalization of the aspect and the broadly understood concept of dynamicity. The article proves that these differences, resulting from different visions of the world (Lozada, 2006) and different conceptualizations of temporality (Evans, 2007; Wilk-Racięska, 2007b), can be of great significance in research of both American Indians and some of the transformations in Spanish language.

Opis:
Badania lichenologiczne prowadzone były w rejonie Doliny Colca, Kanionu Colca oraz Doliny Wulkanów (Andy Centralne), na obszarze piętra roślinnego puna, na wysokości 3000 do 5000 m n.p.m. Na 20 stanowiskach, zlokalizowanych za pomocą odbiornika GPS, zebrano 150 okazów porostów. Z dotychczasowych badań wynika, że dominują tu gatunki skorupiaste, mniej liczne są porosty o plechach plakodiowych, listkowatych lub krzaczkowatych. Gatunki porostów naskalnych najczęściej należą do rodzajów Acarospora, Buellia oraz Psiloparmelia. Porosty epigeiczne i epifity są nieliczne. Wśród porostów epigeicznych najczęściej były notowane gatunki z rodzaju Acarospora, Flavoparmelia, Lecidea, Caloplaca, Lepraria i Physconia. Na zdrewniałych częściach kaktusów zidentyfikowano rodzaje Buellia, Caloplaca, Teloschistes i Xanthoria, a na zdrewniałych tkankach roślin wyższych Physcia, Buellia, Candelariella, Usnea, Parmelia oraz Caloplaca. Badania zmierzają do oznaczenia gatunków oraz oszacowania bioróżnorodności porostów na badanym obszarze.
Lichenological investigations were conducted in the region of Colca Valley, Colca Canyon and Valley of the Volcanoes (Central Andes), in the area of puna, at altitudes between 3000 and 5000 m a.s.l. Specimens were collected on 20 sites, located using GPS receiver. Most of the 150 specimens are crustose lichens. Squamulose, foliose and fruticose lichens are less frequent. Epilithic lichens belong mostly to genera Acarospora, Buellia and Psiloparmelia. Among epigeic lichens most common are species of following genera: Acarospora, Flavoparmelia, Lecidea, Caloplaca, Lepraria and Physconia. On wooden parts of cacti genera: Buellia, Caloplaca, Teloschistes and Xanthoria were identified, and on wooden parts of vascular plants genera: Physcia, Buellia, Candelariella, Usnea, Parmelia and Caloplaca. Now further work is being done to determine the species and the level of lichen biodiversity in this region.

Opis:
Partially preserved temnospondyl mandibles from the Late Permian–Early Triassic Buena Vista Formation of Uruguay are referred to the basal stereospondyl taxon Mastodonsauridae. These represent the earliest known members of this group for South America. In most cases, this assignment was based on the characteristic morphology of the postglenoid (= postarticular) area of the lower jaw together with the presence of a hamate process. Comparisons with basal mastodonsaurids indicate that the Uruguayan specimens are phenetically similar to Gondwanan and Laurasian Early Triassic taxa, such as Watsonisuchus, Wetlugasarus, and Parotosuchus. Nevertherless, they display some characters which have not previously been described in Mesozoic temnospondyls. The Permo−Triassic Uruguayan mastodonsaurids support a Gondwanan origin for the group, an event which probably occurred sometime during the latest Permian.

Opis:
The following paper presents an attempt at a semiotic analysis of socially and politically-oriented street art in the capital of Chile. Based on Charles Sanders Peirce’s theory of semiotics, Siegfried J. Schmidt’s constructivist communication theory, and using the methods of semiotic and discursive analysis by Gillian Rose, a reconstruction of the semantics of murals has been made. Murals are treated here as specific semiotic codes and are linked with social-political-ideological aspects. As a reference point, a mural has been chosen as a communication tool which is typical of Latin America, and also the codes typical in this area, which resulted from previous analyses.
W artykule podjęta została próba semiotycznej analizy społecznie i politycznie zaangażowanej sztuki ulicznej w stolicy Chile. Bazując na teorii semiotyki Charlesa Sandersa Peirce’a, konstruktywistycznej teorii komunikacji Siegfrieda J. Schmidta oraz z wykorzystaniem metod analizy semiotycznej i dyskursywnej Gillian Rose, dokonano rekonstrukcji semantyki murali, traktowanych jako określone kody semiotyczne, oraz ich powiązania z aspektami społeczno-polityczno-ideologicznymi. Za punkt odniesienia przyjęto mural jako narzędzie komunikacji typowe dla Ameryki Łacińskiej i wynikające z uprzednich analiz typowe dla tego obszaru kody.

Opis:
The 19th century in the history of Italy was very difficult and unstable. On the Italian peninsula there were numerous atrocious wars, revolutionary movements and first of all its reunion movement. The above mentioned movements as well as a process of industrialization in the country caused great poverty across the country. That had a negative influence on education of the young and schools. A great number of children and youth were not in education at all. This situation was worsened by the fact of working women in industry. These circumstances led the Italian youth astray. Many people of goodwill and institutions in the country took initiative to the bad tendency on the field of education and school. Saint John Bosco is undoubtedly one of them. He initiated work with the poor and depraved children of Turin. As a young priest, from 1841 to 1844, he took the post of chaplaincy in one of prisons of Turin, where the young offenders were placed. Working as a chaplain he came to conclusion that it is absolutely important to make everything possible to keep children away from prisons where they undergo further moral degradation. Therefore, he started to set up places and youth centres suitable for young boys where free education can be provided for them and they can obtain job qualifications. Thus St. John Bosco founded oratories, schools, educational schools, boarding schools and colleges. In order to have followers of the youth work, he brought a Society of Saint Frances de Sales into being (to work for juvenile boys) and a Society of the Daughters of Mary Help of Christians (to work for juvenile girls). He also created his own system of education called the Preventive System based on mind, religion, love and assistance of the young, as well as family relations among the boys. From 1875 onwards one can notice an ongoing development of the Society of St. Frances de Sales. The Italian society, many European countries and numerous worldwide countries kept asking John Bosco to establish salesian enterprises for youth education in their countries. He had, nevertheless, some real obstacles to implement his ideas in the mentioned countries. Simply, the main problem was the lack of qualified personnel to go ahead with them. This article presents a development of the Society of St. Frances de Sales when the Rector Major was St. John Bosco.

Opis:
The Late Cretaceous South American sauropods Neuquensaurus australis and Saltasaurus loricatus are represented by well−preserved and abundant material that has been integral to our understanding of titanosaur anatomy for decades. Although the hypodigms for these species span most of the skeleton, holotypic materials are limited to a few bones that do not overlap between the two taxa. In this contribution, we augment the holotype of Neuquensaurus australis with a partial sacrum that was preserved in articulation with one of the caudal vertebrae from its original description, but not recognised as such at the time. We document this field association via the presence of a broken piece of matrix on the sixth sacral vertebral centrum that has a snap−fit to matrix on the rim of the anterior condyle of the holotypic biconvex vertebra. Based on comparisons with a more complete sacrum and ilium of a referred specimen of Neuquensaurus australis, we interpret this biconvex vertebra to be the seventh sacral vertebra. This raises the possibility that the biconvex “first caudal” vertebra of some other titanosaurs may be part of the sacrum as well. Augmentation of the Neuquensaurus australis holotype to include a sacrum makes it directly comparable to the holotype of Saltasaurus loricatus. Morphological differences in the number, shape, and proportion of sacral vertebrae allow discrimination between Neuquensaurus and Saltasaurus, confirming their generic separation. The El Brete quarry, which preserves the holotypic sacrum and abundant referred specimens of Saltasaurus loricatus, also preserves a sacrum consisting of seven vertebrae that bears autapomorphies of Neuquensaurus australis, indicating that these two saltasaurines coexisted.

This paper seeks to recover the debate on the cultural inclusion of migrants in the Argentine legal system (1983–2018), paying attention to regional integration initiatives in the South American context. For this, I expose a theoretical sketch around the concept of cultural policy. After that, I analyse the Argentine immigration regulations since 1983, the current immigration law and the legal order that emerged from its promulgation, exposing those points devoted to cultural inclusion. At the same time, I examine the reciprocal influence existing between the Argentine migratory order and the agreements reached by supranational organizations. By way of closing, I explain the incipient institutionalization of regional cultural integration initiatives.
Este artículo tiene por objetivo recuperar el debate en torno a la inclusión cultural de los migrantes en el ordenamiento legal argentino (1983–2018), prestando atención a las iniciativas regionales de integración en el contexto sudamericano. Para ello, se realiza un esbozo teórico en torno al concepto de política cultural. Posteriormente, se analizan las normativas migratorias argentinas desde 1983, la ley migratoria vigente y el ordenamiento legal surgido desde su promulgación, exponiendo aquellos puntos consagrados a la inclusión cultural. Paralelamente, se examina la influencia recíproca existente entre el ordenamiento migratorio argentino y los acuerdos alcanzados por organismos supranacionales. A modo de cierre, se expone la incipiente institucionalización de iniciativas de integración cultural regional.

Opis:
Artykuł jest próbą przedstawienia kontekstu i współczesnego procesu tworzenia społeczności żydowskiej w Iquitos w Peru. Termin „Żydzi amazońscy" odnosi się głównie do potomków XIX-wiecznych marokańskich żydowskich poszukiwaczy przygód, handlarzy i plantatorów, którzy przybyli do amazońskiej dżungli w okresie boomu kauczukowego w latach 80. XIX wieku. Mimo że społeczność ta przechodziła przez pokolenia małżeństw mieszanych, a jej praktyki religijne były pod wpływem katolicyzmu i animizmu, religie amazońskie nadal zachowują silne poczucie żydowskości. Pomimo skrajnej izolacji potomkowie marokańskich Żydów zachowali niektóre tradycje żydowskie i podjęli kilka prób podtrzymania kruchej społeczności. Żydzi z Iquitos, podobnie jak inne rozproszone społeczności, które odwołują się do żydowskich korzeni, próbują budować swoją tożsamość poprzez rewitalizację związków ze społecznością żydowską.
The article is an attempt to present the context and the contemporary process of creating a Jewish community in Iquitos, Peru. The term “Amazonian Jews” refers to mostly descendents of 19th century Moroccan Jewish adventurers, traders and tappers who came to the Amazon jungle during the rubber boom of the 1880s. Thought the community has passed through generations of intermarriage and its religious practices have been influenced by Catholicism and animistic Amazonian religions still preserves a strong sense of Jewish-ness. Despite the extreme isolation the descendents of the Moroccan Jews have kept up some Jewish traditions and made several attempts to sustain a fragile community. The Jews from Iquitos like other dispersed communities which refer to the Jewish roots, attempt to build their identity through the revitalization of their connections with the Jewish community.

We describe a new large species of marabou stork, Leptoptilus patagonicus(Ciconiiformes, Ciconiidae, Leptoptilini), from the late Miocene Puerto Madryn Formation, Chubut Province, Argentina. The specimen consists mainly of wing and leg bones, pelvis, sternum, cervical vertebrae, and a few fragments of the skull. We provisionally adopt the traditional systematic scheme of ciconiid tribes. The specimen is referred to the Leptoptilini on the basis of similarities in morphology and intramembral proportions with the extant genera Ephippiorhynchus, Jabiru, and Leptoptilos. The fossil specimen resembles in overall morphology and size the species of Leptoptilos, but also exhibits several exclusive characters of the sternum, humerus, carpometacarpus, tibiotarsus, and pelvis. Additionally, its wing proportions differ from those of any living taxon, providing support to erect a new species. This is the first record of the tribe Leptoptilini in the Tertiary of South America.

Opis:
The nineteenth century was a very difficult period in the history of Italy (wars, revolutionary movements). These events all contributed to the great impoverishment of Italian society. Many people undertook a number of preventive measures in the field of education in order to make the situation better for the young. Father John Bosco was one of them. From 1841 to 1844, he worked as a chaplain in one of Turin’s prisons in which juvenile delinquents were serving prison sentences. Working with them strengthened Fr. Bosco’s conviction that everything should be done to prevent young people from going to prison. With this goal in mind, John Bosco established various institutions which gave youth a roof over their heads and the opportunity to learn a profession. He also created his own system of education, which he called a preventive system, based on reason, religion and love. Italian society, European countries, and many countries worldwide turned to Fr. Bosco and asked for the Salesians to start educational work. This article presents the development of the Salesian Society in the field of social work and education during the years in which Fr. Michael Rua was Superior General of the Salesians and first successor of John Bosco.

Opis:
Megatherium americanum (late Pleistocene of South America) has traditionally been regarded a herbivore, but its dietary habits have not been considered in terms of a morphofunctional analysis. This study describes and analyses the morphology of the masticatory apparatus in order to interpret the jaw mechanics of M. americanum, and thus to infer its diet and behaviour. The results are compared with those for the mylodontid Glossotherium robustum and the extant sloth Bradypus variegatus. The areas of origin and insertion of the masticatory musculature were reconstructed, and the moment arms generated by this musculature were estimated so that the mechanics of the feeding apparatus might be described. These analyses indicate that M. americanum was well adapted for strong and mainly vertical biting. The teeth are extremely hypsodont and bilophodont, and the sagittal section of each loph is triangular with a sharp edge. This suggests that the teeth were used mainly for cutting, rather than grinding, and that hard and fibrous food was not the main dietary component. The diet of M. americanum merits more rigorous analysis, but the evidence provided here indicates that it probably had a browsing diet in open habitats, but also could have fed on moderate to soft tough food.

Opis:
An article investigates the role of religion in life of Belarusian emigrants in Argentina. The key subject of the research is an analysis of the Orthodox Church development and Belarusians’ participation in its activity. Besides, the author describes the role of certain Belarusian Orthodox priests serving in South America (Aphanasy Martos, Walentin, Iwaszewicz). The author concludes that emigration led to the decrease of level of religiousness of Belarusians. Orthodox churches became just  meeting places for emigrants and served as connecting thread with homeland, memory of which was accompanied by  acute nostalgia.
Статья посвящена осмыслению роли религии в жизни эмигрантов-белорусов в Аргентине. Основное содержание исследования составляет анализ развития православной церкви и участие белорусов в ее жизнедеятельности. Раскрывается роль и отдельных священников-белорусов, служивших на ниве православия в Южной Америке (Афанасия Мартоса, Валентина Ивашевича). Автор приходит к выводу, что эмиграция приводила к снижению уровня религиозности белорусов, а православные церкви становились для эмигрантов, по большей части, местом встреч и связующей нитью со своей родиной, воспоминания о которой сопровождались острым чувством ностальгии.

Artykuł jest pierwszym doniesieniem o długofalowym projekcie, mającym na celu poznanie różnorodności gatunkowej mszaków i porostów na obszarze projektowanego Parku Narodowego Kanion Colca i Dolina Wulkanów (Arequipa, Peru) oraz ich ekologii w kontekście zróżnicowania środowiska abiotycznego. Środowisko przyrodnicze tego najgłębszego kanionu świata nie doczekało się dotychczas kompleksowego opracowania flory mszaków i porostów. Już na podstawie wstępnych obserwacji stwierdzono ich znaczący udział w szacie roślinnej tego obszaru oraz potencjalnie duże bogactwo gatunkowe wynikające ze znacznego zróżnicowania siedlisk. Istotnym wynikiem rozpoczętych badań jest odkrycie pierwszych stanowisk porostów Lecanora leuckertiana w Ameryce Południowej i Lepraria impossibilis na Półkuli Południowej. Dalsze badania powinny zaowocować opracowaniem pełnej listy gatunków mszaków i porostów Parku Narodowego Kanion Colca i Dolina Wulkanów oraz dostarczyć argumentów do ochrony jego unikalnej przyrody.
The paper is a preliminary report of a long-term project that aims at completing the flora of bryophytes and lichens in the projected Canyon Colca and the Valley of the Volcanoes National Park area (Arequipa, Peru). The bryophytes and lichens of this deepest canyon in the world has remained underexplored for a long time. These organisms dominate in the vegetation cover and exhibit a remarkable species diversity resulting from habitat richness in this area. The important result of preliminary studies was discovered the first records of lichens Lecanora leuckertiana in South America and Lepraria impossibilis in the Southern Hemisphere. Further researeh should result in completing floristic lists of bryophytes and lichens of the Canyon Colca and the Valley of the Volcanoes National Park and should provide arguments for the protection of its unique wild life.

Tematyka duszpasterskiej działalności rektora Polskiej Misji Katolickiej w Argentynie o. Lucjana Łuszczkiego OFM (1910-1991) to tylko przyczynek do dalszych badań nad osobą zakonnika. Ukazano jego dorobek na tle krótkiego życiorysu, ze wskazaniem najważniejszych wydarzeń przypadających na pobyt w Ameryce Południowej – obchody Tysiąclecia Polski (1966) oraz wizyta duszpasterska biskupa Władysława Rubina (1968). Poprzez pracę zakonnika zobrazowano także polską społeczność zamieszkującą Amerykę Łacińską oraz jej sytuację polityczną i problemy życia codziennego.
The article presents the life and work of Fr. Lucjan Łuszczki (1910-1991) a Polish monk who was active in South America, latterly as Rector of the Polish Catholic Mission in Argentina where he oversaw the Millennium celebrations of Poland’s Christianity (1966) and the pastoral visit of Bishop Władysław Rubin (1968). Through the prism of Fr. Łuszczki’s pastoral work the article also paints a picture of the life of Polish diaspora in South America – the political, social, economic and everyday life issues with which they had to contend.

Opis:
The Frasnian-Famennian (F-F) mass extinctions saw the global loss of all genera belonging to the tropically confined order Atrypida (and Pentamerida): though Famennian forms have been reported in the literafure, none can be confirmed. Losses were more severe during the Givetian (including the extinction of the suborder Davidsoniidina, and the reduction of the suborder Lissatrypidina to a single genus), but origination rates in the remaining suborder surviving into the Frasnian kept the group alive, though much reduced in biodiversity from the late Early and Middle Devonian. In the terminal phases of the late Palmatolepis rhenana and P. linguiformis zones at the end of the Frasnian, during which the last few Atrypidae dechned, no new genera originated, and thus the Atrypida were extirpated. There is no evidence for an abrupt termination of all lineages at the F-F boundary, nor that the Atrypida were abundant at this time, since all groups were in decline and impoverished. Atypida were well established in dysaerobic, muddy substrate, reef lagoonal and off-reef deeper water settings in the late Givetian and Frasnian, alongside a range of brachiopod orders which sailed through the F-F boundary: tropical shelf anoxia or hypoxia seems implausible as a cause for atrypid extinction. Glacial-interglacial climate cycles recorded in South America for the Late Devonian, and their synchronous global cooling effect in low latitudes, as well as loss of the reef habitat and shelf area reduction, remain as the most likely combined scenarios for the mass extinction events.

Combating hunger and malnutrition and ensuring food security are global priorities for action, set out in Agenda 2030, under Goal 2: Zero Hunger. Its implementation requires complex and coordinated action at both national and international levels and the development of an effective model of food security governance in the future. Latin America is an interesting example of the regionalization of food security governance. The study aims to analyze the Latin American model with particular emphasis on the role of regional organizations, and to demonstrate that the regional food security governance model is based on the South-South cooperation mechanism, which promotes cooperation and joint actions of developing countries. The analysis is based on two assumptions: first, due to the multidimensional nature of food security, the importance of cooperation and multilateral solutions is growing; second, the North-South model of cooperation, which dominates international development, becomes insufficient in the face of new challenges and is supplemented by other arrangements. As a result, the South-South and intra-regional cooperation is gaining in importance in Latin America.
Combatir el hambre y la desnutrición y garantizar la seguridad alimentaria son prioridades globales de acción, establecidas en la Agenda 2030, en el Objetivo 2: Hambre Cero. Su implementación requiere una acción compleja y coordinada a nivel nacional e internacional y el desarrollo de un modelo efectivo de gobernanza de la seguridad alimentaria en el futuro. América Latina es un ejemplo interesante de la regionalización de la gobernanza de la seguridad alimentaria. El estudio tiene como objetivo analizar el modelo latinoamericano con especial énfasis en el papel de las organizaciones regionales y demostrar que el modelo regional de gobernanza de la seguridad alimentaria se basa en el mecanismo de cooperación Sur-Sur, que promueve la cooperación y las acciones conjuntas de los países en desarrollo. El análisis se basa en dos supuestos: primero, debido a la naturaleza multidimensional de la seguridad alimentaria, está creciendo la importancia de la cooperación y las soluciones multilaterales; segundo, ante los nuevos desafíos, el modelo de la cooperación Norte-Sur, que domina el desarrollo internacional, se vuelve insuficiente y tiene que complementarse con otros arreglos. Como resultado, la cooperación Sur-Sur e intrarregional está ganando importancia en América Latina.

Opis:
Geologists of the Polish Geological Institute carried out their professional activities abroad as part of geological expeditions, in teams of several people and on individual contracts, including as experts of the United Nations. In terms of the scope of work, most of their activities were focued on research on mineral resources, mapping, geochemistry, hydrogeology and geophysics, as well as on teaching of geology at the university level. The beginnings date back to the turn of the 1950s. It began with a geological expedition to Vietnam. Mongolia was the goal of subsequent expeditions on a much wider scale. The researches were conducted from the beginning of the 1960s until the end of the 1980s. The contracts, performed in groups of several people and individually, covered about 20 countries; most of them on the African continent. They focused primarily on the search for metal ore deposits, hard coal, and chemical and rock raw materials. PGI geologists also worked as UN experts in Benin, Burundi, Chad, Gabon, Haiti, India, Madagascar, Mauritania and Niger. The results of their work on various continents were the discoveries of numerous mineral deposits and the recognition of geological structure over an area of thousands of square kilometres.

To achieve a better understanding of predation pattern recorded in the fossil record it is essential to study predator−prey interactions in the modern seas. It includes the data collected from the field observations as well as from the experiments in captivity. Such an approach allows recognition of the bioeroders, its description and also provides quantification of these interactions. This work offers a case study of the traces of predation resulting from the predator−prey interactions between three mussels: Mytilus chilensis, Brachidontes purpuratus, and Aulacomya atra; and their five natural enemies: the gastropods Trophon geversianus, Xymenopsis muriciformis, and Acanthina monodon, and the asteroids Cosmasterias lurida and Anasterias antarctica living along the intertidal and/or subtidal rocky shores in Tierra del Fuego. The predatory damage to mussel shells varies according to the predator and prey species and techniques for attacking prey are highly specialized. A. monodon drills a hole in B. purpuratus but uses the outer lip of its shell as a wedge to open the valves of M. chilensis and A. atra. T. geversianus always makes holes, but while it drills the valve walls of M. chilensis, it prefers to drill the valve edges of A. atra and B. purpuratus, with different characteristic patterns. Usually the shells of mussels killed by C. lurida do not suffer from any mechanical damage, but some other shells were crushed or fractured along the margins. Comparatively, time required to successfully attack a prey was shorter in C. lurida (24 hours), followed by A. monodon (36 hours), and longer in T. geversianus (9 to 10 days). Traces of predation are not randomly distributed across size classes of mussel prey, reflecting selectivity for a particular size class. Also, drill holes are usually placed at specific sectors of the shell, indicating site selectivity. These observations offer some paleontological implications for investigating the pattern of predation in fossil record. They show that different patterns of shell damage can be due to different predator species (e.g., wall vs. edge drillings), although the same predator species can leave different marks when consuming different prey (e.g., T. geversianus). Most disconcerting for paleontologists are cases of predation which do not leave any marks on the prey shell detectable in the fossil record (e.g., predation by asteroids), or leave ambiguous marks (A. monodon when preying with the spine). In conclusion, besides the opportunity to identify some traces of predation by drilling gastropods in fossil mussels, this work gives criteria to address predation in some particular paleontological cases that would otherwise be dismissed by researchers.

W artykule autor opisuje ceramikę kultury Nasca, która rozwijała się w rejonie południowej części wybrzeża peruwiańskiego w okresie około 1-700 n.e. Ceramicy z tego dawnego indiańskiego społeczeństwa za pomocą prostych technik stworzyli niezwykle barwne i kunsztownie wykonane naczynia. Wyroby te zostały ozdobione za pomocą zastosowania różnokolorowych angob. W działalności tej garncarze z kultury Nasca osiągnęli mistrzostwo, któremu nie dorównała żadna inna kultura z tego obszaru. W artykule opisano proces wytwarzania oraz ozdabiania naczyń. Omówiono również sceny i wizerunki umieszczone na ceramikach.
In the article the author describes the ceramics of the Nasca culture which developed on the southern Peruvian coast in the period of approximately A.D. 1-700. The ceramists of this ancient Indian society created extraordinarily colorful and masterfully made vessels with the use of simple techniques. The wares were decorated with the use of multicolor slips. The ancient Nasca potters achieved in this activity mastery which wasn't surpassed by any other culture from this area. In the article the process of vessels production and decoration was described. Scenes and images which were depicted on the ceramics are also discussed.

Opis:
The aim of this article is to analyse the issue of “weak separatism” in Latin America as well as to give an answer to the question why there are no significant separatist movements in this region. The authors provide the definitions of separatism and secessionism as well as an explanation of these phenomena. Moreover, they present an overview of historical and contemporary separatist movements in Latin America. Based on Horowitz’s theory of ethnic separatism, the authors attempt to analyse the separatist movement “The South is My Country” in Brazil and compare it with separatism in Catalonia in Spain, where a referendum on independence from Spain was held in 2017, serving as an impetus for a similar referendum that took place in the South of Brazil. In spite of similar goals of these two separatist movements, the authors argue that there are significant differences in their nature, which are determined by the history and culture of the respective countries.
