Opis:
Genetic diversity of Galium cracoviense, a narrow endemic species, limited to the small area in southern Poland and concentrated on Jurassic limestone outcrops near Częstochowa, was examined using the AFLP marker. Twenty nine individuals from three spatially isolated populations were used for the study. AFLP analysis yielded 157 bands, of which 110 (70%) were polymorphic. The AMOVA analysis revealed a substantially higher variation within populations (89.35%) than among them (10.65%). Values of parameters describing population genetic diversity, such as Shannon index and gene diversity index estimated for each population, were highly similar. The results indicate a high level of genetic polymorphism as well as a high genetic similarity of the isolated populations of G. cracoviense and thus an unconstrained gene flow between them. Based on the results we conclude that additional demographic and genetic studies, are necessary to monitor potential decrease of populations size resulting mainly from the mechanical destruction of plants and their habitats caused by intense tourism. Due to the small general range of occurrence, conservation should include the highest possible number of populations of G. cracoviense.

Opis:
The paper deals with the richness and diversity of endemic and subendemic taxa in the Polish Carpathians. Based on critical studies in the literature and the authors' unpublished materials collected in the field, the distribution patterns of endemic species are analysed and discussed. The participation of endemics in the flora of single Carpathian ranges is assessed and analysed. The importance of the Tatra Mts as a centre of endemism is stressed. The frequency and altitudinal ranges of endemic taxa are characterized and their syntaxonomical spectrum is presented.

Opis:
In this paper, the rediscovery of endemic and long missing species, Scilla mesopotamica Speta which had been only known from the type gathering, is given. The species has not been collected again after Sintenis in 1888, whose specimens served Speta for description of the new taxon. In 2004, the authors found it in a steppic rocky area, near Halfeti in Şanliurfa province, South East Anatolia, Turkey. After analyzing Sintenis' original collection notes, they concluded that this area is identical with the type locality. S. mesopotamica has an extremely limited distribution and is represented by less than 200 specimens in the single known population that covers less than 50 m2. Taxonomy of the species, detailed description with illustrations, geographical distribution, habitat, ecology and status of IUCN extinction risk and some comments on conservation of the plant are also presented.

Opis:
The mycorrhizal status of 24 plant species considered as endemic, endangered in Poland and included in the IUCN Red List of Threatened Plants is reported. Selected plants and rhizosphere soil samples were collected in the Tatra Mts (Western Carpathians). Individuals of seriously threatened taxa were obtained from seeds and inoculated with available AM fungal strains under laboratory conditions. AM colonisation was found in 16 plants; 9 species were of the Arum-type, 4 - Paris and 3 taxa revealed intermediate morphology. The mycelium of the fine endophyte (Glomus tenue) and dark septate fungi (DSE) were observed in the material collected in the field. 20 AMF species (Glomeromycota) found in the rhizosphere of the investigated plants were reported for the first time from the Tatra Mts. The results provide information that might be useful for conservation and restoration programmes of these species. Application of AMF in active plant protection projects is discussed.

Essential oils from the leaves, stems and flowers of Postia puberula at the flowering stage were analyzed using GC and GC/MS. The results showed that leaves are abundant of cis-3-hexenyl benzoate (10.75%), benzyl benzoate (8.16%) and caryophyllene oxide (8.12%). The main compounds of stems were benzyl benzoate (21.92%), E-nuciferol (11.58%) and dibutyl phthalate (7.08%), while major components of flowers were benzyl benzoate (9.99%), caryophyllene oxide (8.14%) and E-nuciferol (8.13%). The antioxidant activities of methanol extract were evaluated by DPPH and β-carotene/linoleic acid assays. The results showed that in both methods, leaves had stronger antioxidant activity than other organs.

Faster R-CNN is an algorithm development that continuously starts from CNN then R-CNN and Faster R-CNN. The development of the algorithm is needed to test whether the heuristic algorithm has optimal provisions. Broadly speaking, faster R-CNN is included in algorithms that are able to solve neural network and machine learning problems to detect a moving object. One of the moving objects in the current phenomenon is the use of masks. Where various countries in the world have issued endemic orations after the Covid 19 pandemic occurred. Detection tool has been prepared that has been tested at the mandatory mask door, namely for mask users. In this paper, the role of the Faster R-CNN algorithm has been carried out to detect masks poured on Internet of Thinks (IoT) devices to automatically open doors for standard mask users. From the results received that testing on the detection of moving mask objects when used reaches 100% optimal at a distance of 0.5 to 1 meter and 95% at a distance of 1.5 to 2 meters so that the process of sending detection signals to IoT devices can be carried out at a distance of 1 meter at the position mask users to automatic doors.

In this research work, a deterministic mathematical model for schistosomiasis transmission dynamics is presented. The model consists of five non-liniar ordinary differential equations incorporating the acute and chronic infectious compartments. The basic reproductive number, (the number of secondary infections when a single infectious individual is introduced into a population where everyone is susceptible) was obtained. Furthermore, we gained and analyzed for stability, the disease-free and endemic equilibrium. The qualitative feature of the model shows that the long-term behavior of the model is independent of initial conditions. Numerical simulation of the various state variables were obtained using matlab software.

Opis:
We present a study of the distribution, ecology and conservation status of Cupressus atlantica, an endemic tree of the High Atlas (Morocco). The main populations of this species grow in a reduced area along the N’Fiss valley in the Central High Atlas and are gradually receding. Particular populations are increasingly fragmented and the total area covered by the cypress woodland has decreased to less than a third of the surface occupied in the 1930s. Overgrazing reduces the woodlands’ regenerative capacity, and the exploitation of the wood, linked to traditional uses by the rural society of the N’Fiss valley, directly reduces the number of trees. Great efforts being made to protect the species by the Haut Commissariat aux Eaux et Forêts are having some effect in recent years.

Opis:
Dionysia involucrata Zaprjag. (Primulaceae) is known as critically endangered endemic species of Hissar Mountains in Tajikistan. It is reported from few localities mainly in Varzob River valley and its tributaries. The species inhabits steep or overhanging faces of granite rocks in narrow river gorges. During the research all known populations of D. involucrata were examined in respect of the habitat conditions and species composition of vegetation plots. We analyzed the population extent of the species in its range in Tajikistan and the main threats in order to assess its conservation status. The detrended correspondence analysis was performed on a matrix of 65 relevés and 49 species (vascular plants and mosses), to classify the phytocoenosis with domination of D. involucrata according to their floristic composition in relation to other petrophytic vegetation units. Using our field data regarding present extent of occurrence and area of occupancy we conclude that the threat category of D. involucrata should be reassessed from critically endangered to endangered. The species shows decline tendency in extent of occurrence, area of occupancy as well as in number of locations. The vegetation plots with domination of D. involucrata have relatively high level of separateness due to different species composition. We define the new association – Dionysietum involucratae – representing chasmophytic vegetation of submontane and montane zone in Middle Asia (ca. 1000–1600 m a.s.l.). The plots of Dionysietum involucratae were found mainly on granite rocks, on very steep or overhanging faces, on southwestern or southern exposition. The association is rather poor in species with inconsiderable contribution of mosses. Despite the diagnostic species, Campanula incanescens, Carex koshewnikowii and Scutellaria hissarica were the most abundant and frequent taxa within the researched patches of vegetation.

Opis:
Autumn daffodil (Sternbergia lutea) is a rare and endangered bulbous plant with yellow flowers grown naturally in Iran and unfortunately for different reasons this plant is at the risk of eradication. Natural multiplication rate of S. lutea is low, thus propagation by chipping method is one inexpensive and simple way to overcome this problem. This research was therefore performed to investigate the propagation method in two experiments. In the first experiment, the effects of some plant growth regulators (PGRs) on induction and regeneration of bulblets from bulb chips (propagules) were evaluated. The propagules were prepared by chipping method and treated with indole butyric acid (IBA), gibberellic acid (GA3), benzyl adenine (BA), kinetin (Kin) and cycocel (CCC) at 100 and 200 mg L–1 concentrations for 2 h and then incubated for two months at 20 ±1°C. At the end of incubation, the results showed the highest percentage of concurrent bulblet + root regeneration (CBRR), number and fresh weight of bulblets related to 100 mg L–1 GA3. The highest percentage of only bulblet regeneration (OBR), only root regeneration (ORR) and non-regeneration were obtained at 200 mg L–1 IBA, 100 mg L–1 Kin and control (distillated water: DW) treatments, respectively. In the second experiment, the bulblets that had rooted from each treatment of the first experiment were planted and the produced bulbs were compared. The results indicated that the highest percentage of bulblet sprouting, bulb number and diameter were found at 100 mg L–1 GA3. Therefore, the application of GA3 with mentioned concentration is appropriate for vegetative propagation of this plant by bulb chipping.

Opis:
Allium tuncelianum (Tunceli garlic) is a single cloved important threatened endemic geophyte of high commercial importance that grows scattered on hot temperate mountains under oak trees in the eastern Turkish province of Tunceli. Tunceli garlic is used diversely in salads, foods and in pharmaceutical industry. They also offer a rich choice for their use in rock gardens and landscaping. There is need to develop appropriate agronomic practices for its propagation outside its habitat. In line with this objective, the study optimized planting time (1st September, 15th September and 1st October) of A. tuncelianum on mild alkaline soils under semi-arid climatic conditions of Diyarbakir, Turkey. The results of the study showed positive gain in morphological characteristics such that bulb diameter of the plants changed between 3.43 to 4.60 cm, bulb circumference ranged 14.4 to 16.1 cm and bulb weight had a range of 35.9 and 46.3 g. These results underscore positive effects of early and mid September plantings of Tunceli garlic outside its habitat under semi-arid conditions for economic production with early harvest.

Opis:
This study was performed to depict the anatomical changes in apical meristems in order to determine the flower initiation and development of Iranian lily (Lilium ledebourii). Observations carried out by scanning electron microscope (SEM) on groups of bulbs with different age and size showed that only large (≥55 g and ≥6 cm in diameter) 9-year-old and older bulbs expressed flowering transition, abandoning the juvenile condition. The switch from vegetative to reproductive in the apical meristem was characterized by flattening its dome. Flower initiation started between 10 and 20 days after planting, once the bulbs have passed a period of vernalization of two months at 3°C. The first hint of floral organ definition was noted 30 to 50 days after planting when the outer perianths started to grow followed by inner perianths in a pattern of 3−3. After complementation of flower formation by stamen and pistil appearance and development, flower abortion occurred in some bulbs 30 days after flower initiation. Flower bud abortion could not be linked to the bulb size. Identification of the exact time of flower initiation will be useful to provide proper management of Iranian lily in the process of domestication of this endemic endangered lily.

Opis:
Cochlearia polonica Fröhl. (Brassicaceae) is one of the rarest species in the Polish and European flora and a taxon endemic to a very small area in southern Poland. Due to industrial activities and subsequent transformation of habitats it was extinct in all natural localities around 1994. The persistence of the species was ensured thanks to the active protection efforts including a series of transplantations based on the material from the last and decreasing natural population. The history of conservation efforts of C. polonica provides a model example of successful active protection in the European flora. Here, we provide a complete review comprising the following aims: (i) outline of the discovery and taxonomic conceptions on C. polonica, (ii) review of conservation efforts aimed at preserving its populations, (iii) description of the existing population resources, and (iv) analysis of the genetic structure of all existing populations based on previously published data and new, supplementary results.

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.

Opis:
The present study is the first quantitative comparison of Sarmatian mollusc assemblages from the Central and Eastern Paratethys seas. The assemblages (47,840 shells, 32 samples, 84 species) derive from eight Middle and Upper Miocene localities covering an interval from 12.7–11.0 Ma, when a highly endemic mollusc fauna flourished in the entire Paratethys. Cluster analysis of samples yields two major clusters: one composed of late Sarmatian (Bessarabian) collections and the other composed of early Sarmatian (Volhynian) collections. The Volhynian cluster includes two subclusters: the first reflects a strong stratigraphic signal because it combines samples from the Mohrensternia Zone of the Vienna Basin and the western Ukraine. The second combines samples from the Upper Ervilia Zone of the Vienna Basin with samples from the Mohrensternia Zone of the Vienna Basin and Romania. Cluster analysis of species indicates that the sample clusters represent different palaeoenvironments with distinct molluscan assemblages: The Volhynian wellagitated shore is characterized by the Granulolabium–Venerupis–Ervilia biofacies, the Volhynian muddy foreshore by the Granulolabium–Mohrensternia–Ervilia biofacies, and the Bessarabian shallow to medium deep sublittoral by the Hydrobia–Venerupis–Pseudamnicola biofacies. Although not all biozones and regions of the Sarmatian Sea are covered, we suggest that these biofacies cover a wide range of possible assemblage compositions of Sarmatian nearshore and shallow−water assemblages.

The Carpathians, particularly their highest massif, the Tatra Mountains, exhibit the greatest richness of endemics in Poland. The present paper is a critical recapitulation of existing knowledge of endemism among the vascular plants of the Polish part of the Carpathians. It comprises a list of all 110 taxa (49 species, 26 microspecies of the genus Alchemilla and 35 conspicuous subspecies) that can be considered Carpathian endemics or subendemics. Their distribution, vertical ranges and habitats are characterized.

Opis:
Fossil rodents are generally scarce in the Miocene of Japan. However, as much as three taxa of eomyid rodents had been reported from the early Miocene Nakamura Formation (ca. 18.5 Ma) in Gifu Prefecture, central Japan. In this study, we revisit one of them—the small-sized taxon—and assign this material to a new genus, Japaneomys, which is so far known only from the type locality. The new genus is closely related to but distinguished from Asianeomys, which is more widely distributed in Central and East Asia, by having: (i) more bunodont cheek teeth with lower lophids, yet complete transverse lophids; (ii) two-rooted p4; (iii) anterior lobe narrower than posterior lobe on m1, correspondingly synclinid I shorter and shallower than synclinid IV; (iv) hypolophid anteriorly concave on m1. Japaneomys shows a derived but peculiar four-layered enamel microstructure with longitudinally oriented Hunter-Schreger bands, compared to three-layered microstructure in typical eomyid rodents. A phylogenetic analysis indicates that Japaneomys is more basal than Asianeomys and likely diverged in the late Oligocene when Japan was still part of the eastern margin of continental Asia, suggesting that certain small mammal populations could have undergone allopatric speciation isolated from inner-continental regions of Asia.

Opis:
Three species of a Chinese endemic genus Stilpnodiscus Möllendorff, two of them (S. moellendorffi and S. yeni) new, are conchologically and anatomically examined, based on material from Gansu and Sichuan Provinces, W China. Their genitalia are described in detail; a finger-shaped structure of unknown function, found in S. moellendorffi sp. n., is unique among bradybaenids. Definition of the genus is discussed. Principal component analysis of seven metric characters and two coefficients reveals a compatibility of conchological features between the two new species. Their conchological resemblance, combined with the great dissimilarity of the dart sac and sympatric distribution, suggests a particular speciation process.

Opis:
Hladnikia pastinacifolia Rchb., a narrow endemic, has an extremely restricted distribution in Trnovski gozd (Slovenia), despite the presence of many sites with suitable habitats. We compared the morphological traits of plants from different populations and habitats. The overall pattern showed that the smallest plants, with low fruit number, are found on Èaven (locus classicus or type locality); the largest individuals, with high fruit number, grow in the Golobnica gorge. As judged by plant size and seed set, the optimal habitats are screes. We used RAPD markers to estimate genetic variation between and within populations, as well as between and within the northern and the southern parts of the distribution area. Hladnikia showed only a low level of RAPD variability. AMOVA partitioned the majority of genetic diversity within selected populations. The low genetic differentiation between populations and their genetic depauperation indicates survival in situ, since the Trnovski gozd plateau most likely was a nunatak region in the southern Prealps during Pleistocene glaciations. Later range expansion of extant populations was limited by poor seed dispersal. We also analyzed the cpDNA trnL-F intergenic spacer to check whether the sequence is useful for studying the phylogenetic relationships of Hladnikia within the family Apiaceae (Umbelliferae). Our results support the assertion that H. pastinacifolia is an old taxon.

Opis:
In the rich and evolving research of trust there are two opposite theoretical approaches. One in the tradition of Alexis de Tocqueville (1835), Robert Putnam (1993), Francis Fukuyama (1995) and many others considers trust as a quality of interpersonal relations emerging from below, turning into shared cultural resource and producing viable democracy and prosperous economy. The causal vector is from micro to macro, from interpersonal networks to organizations, institutions and the state. This is the dominant approach. But there is also an alternative perspective which claims that trust is facilitated or even enforced by the “civilized public sphere” (Papakostas 2012), or “institutionalized skepticism” (Cleary and Stokes 2006), i.e. the rational political and economic organization, and particularly the clear, stable, transparent and consistent law universalistically and efficiently applied and executed. Here the causal vector is from the state, organizations and institutions toward interpersonal trust, from macro to micro. Both approaches should not be considered as competing but rather as complementary. They have also different but complementary implications concerning the resolution of intergroup conflicts by building trust. For example, the earlier suggests cultivating trust from below by encouraging personal contacts, mutual acquaintance, cooperation, participation in common voluntary ventures by hostile groups. The latter approach would rather emphasize the need for enforcing trustworthiness by overarching, higher-level structure of organizations, institutions and laws assuring accountability, stability, transparency of social relations, through control and surveillance of both feuding parties. It is only the parallel employment of emergence and enforcement of trust that opens the possibility of gradual resolving of intergroup conflict.
W bogatych i rozwijających się badaniach na temat zaufania można wyróżnić dwa kontrastujące ze sobą podejścia teoretyczne. Pierwsze, zakorzenione w tradycji autorów takich jak Alexis de Tocqueville (1835), Robert Putnam (1993) czy Francis Fukuyama (1995), ujmuje zaufanie jako jakość relacji międzyludzkich, która pojawia się oddolnie by następnie stać się kulturowym zasobem niezbędnym do utrzymania trwałej demokracji i dobrze prosperującej gospodarki. Wektor przyczynowy przebiega tu w kierunku od mikro do makro – od sieci międzyludzkich po organizacje, instytucje i państwo. To podejście jest podejściem dominującym. Ale istnieje też ujęcie alternatywne, zgodnie z którym zaufanie powstaje dzięki, lub w całości za sprawą, „cywilizowanej sfery publicznej” (Papakostas, 2012) czy też „zinstytucjonalizowanego sceptycyzmu (Cleary and Stokes, 2006), na który składa się racjonalna organizacja polityczno-gospodarcza, a w szczególności przejrzyste, stabilne i konsekwentne prawo, które jest powszechnie i skutecznie wdrażane i egzekwowane. Tutaj wektor przyczynowy biegnie w kierunku makro-mikro, od państwa, organizacji i instytucji do zaufania na poziomie interpersonalnym. Te dwa pojęcia należy traktować nie jako sprzeczne, lecz uzupełniające się. Co ważne ich implikacje w zakresie rozwiązywania konfliktów grupowych za pomocą budowania zaufania też się uzupełniają. I tak na przykład pierwsze podejście zakłada kultywowanie zaufania oddolnie poprzez promowanie kontaktów międzyludzkich, współpracy i dobrowolnego udziału członków wrogich grup we wspólnych przedsięwzięciach. Drugie natomiast kładzie raczej nacisk na potrzebę wzmacniania zaufania przy pomocy odgórnych struktur organizacji i instytucji oraz praw gwarantujących odpowiedzialność, stabilność i przejrzystość relacji społecznych poprzez kontrolę i uważne obserwowanie członków zwaśnionych grup. Bowiem tylko połączenie przejrzystości i konsekwentnego budowania zaufania daje możliwość stopniowego rozwiązywania konfliktów grupowych.

In this paper, a deterministic mathematical model for the transmission dynamics of Visceral leishmaniasis (VL) was formulated and analyzed. The basic reproductive number R0 was obtained using the next generation matrix method. The model which was parameterized using the 2011 cases of Visceral Leishmaniasis in South Sudan, was used to assess two control measures. Numerical simulation reveals that the exposed population is reduced by high detection rate, and low biting rate of sandflies. Further, our model simulation gave the values of the contact rate of susceptible human, α1 and the detection rate of new cases, σ at which the basic reproductive number is less than one, (R0 < 1), equal to one (R0 = 1) and greater than one (R0 > 1).

Opis:
The taxonomic position of the Antarctic subendemic species Didymodon gelidus Cardot is controversial, notably because of its notorious sterile condition. Considering the overall appearance and the reddish coloration of the plants, the leaf areolation, reaction of the leaf lamina with KOH, and the presence of multicellular axillary gemmae, this species was considered to be conspecific with the Holarctic D. brachyphyllus (Sull.) R. H. Zander. As a result, the latter was established as a bipolar species. Recent detailed morphological and anatomical studies have revealed a number of features which enable recognition of D. gelidus and D. brachyphyllus, including the shape of leaves, leaf apices and basal leaf cells, as well as costal anatomy. Here, within a larger-scale project focused on the evolution and biogeographical connections of Antarctic endemic mosses, we analyzed the genetic relationships of D. gelidus and D. brachyphyllus to confront the morphology-based conclusions. We selected five geographically distinct collections per species and applied a multilocus DNA analysis based on nuclear (ITS) and plastid (atpIH, trnLF, trnG, rps4) sequences to assess the genetic differentiation of these two taxa. We also placed their lineages in a wider phylogenetic context using an extended sampling of Didymodon taxa and select other representatives of Pottiaceae. Our results showed a clear genetic differentiation of the Southern Hemisphere (D. gelidus) and Northern Hemisphere (D. brachyphyllus) plants. Moreover, the phylogenetic analysis showed that D. gelidus formed a strongly supported clade on its own which was distantly related to D. brachyphyllus. Accordingly, the two taxa do not represent geographical vicariants. Didymodon gelidus must be considered a distinct endemic species of the austral polar region, having its optimal occurrence in the Antarctic and weakly penetrating northward to South Georgia and Îles Kerguelen in the Subantarctic. The relatively isolated phylogenetic position of D. gelidus likely suggests its old age.

Opis:
Galapagos is a natural laboratory offering a great opportunity to study plants functional traits. This study characterises morphological and ecophysiological responses of Croton scouleri, an endemic tree that habits from humid and upper elevations to semiarid lowlands, throughout an altitudinal gradient and in a manipulative experiment. Croton scouleri trees were gradually smaller with less total leaf area due to a gradual reduction in mean leaf size, and they folded their leaves at lower elevations. These results were also recorded after cutting every deep root. Two physiological traits that allowed Croton scouleri to avoid damages to the photosynthetic apparatus were detected between 30 and 150 m a.s.l. Lower variable fluorescence (Fv) and basal fluorescence (F0) keeping constant maximum photochemical efficiency of PSII (Fv/Fm) denoted a drop in chlorophyll concentration. Concomitantly, the recorded increase in the Quantum efficiency of PSII (ΦPSII) with similar Fv/Fm means that Croton scouleri could be using cyclic electron transport as photoprotective mechanism. On the other hand, a deep root system to reach the water table allowed Croton scouleri to behave as a drought-avoider, which was reflected in: (1) unvarying water status Leaf Water Content and Relative Water Content were always higher than 69 and 58%, respectively; (2) stable and low photoinhibition levels; and (3) unvarying leaf area index. However, Croton scouleri was not able to avoid drought at altitudes lower 30 m a.s.l. where similar responses to those recorded after root cutting were recorded.

Opis:
Aspects of human infection with Onchocerca volvulus was investigated in 9 villages in Okigwe LGA of Imo State, Nigeria between January 2010 and December 2011. The objectives were to compare the prevalence of different manifestations of Onchocerciasis according to gender and age, with view to determine if there had been a change in prevalence of Onchocerciasis among residents of some communities in Okigwe Local Government Area of Imo State. A cross sectional survey method was adopted for the study, blood free skin snips were collected from randomly selected consenting adults aged 5-62 years. Palpation for mobile subcutaneous lumps and clinical manifestation were observed among 960 persons comprising 511 males and 449 females. The commonest lesions observed were poor vision 17 %, nodules 15 %, leopard skin 20 %, lizard skin 15 %, and hanging groin 3 %. Musculo-skeletal pain (MSP) was recorded as one of the major complaints by 30 % of the subjects. The result showed that Onchocerciasis clinical manifestations are still prevalent, however nodules prevalence reduced among the sampled population (69.8 %).

Opis:
Global warming, globalisation, and constantly increasing number of people involved in long-distance tourism and travel to exotic destinations are likely to increase the number of cases of exotic diseases „imported” to nonendemic countries. One of the often forgotten and neglected diseases has been visceral leishmaniasis (VL or kala-azar). The disease is endemic to 62 countries, with India and Sudan accounting for the majority of the cases. It is typically fatal if left untreated. Each year about 500 000 new cases are reported worldwide, and 50 000 die as a result of the disease. Kala-azar is present in the Mediterranean Europe and 70% of cases are imported to non-endemic countries of European Union from that area. Immunocompromised status of patients, like HIV carriers are the principal prospective target for kala-azar. HIV/VL-coinfected patients have significantly higher relapse rates and decreased life expectancy. There is no formal system of reporting imported cases in Europe, except from Germany. In non-endemic countries, including Poland, there is usually the substantial delay between the onset of symptoms and the final diagnosis, with an average exceeding 3 months. This fact suggests that physicians are not familiar with leishmania infections. Despite progress in vaccine development, the only way to prevent the infection is avoiding sandfly bites. Mosquito nets, wearing appropriate clothes and repellents containing DEET (diethyl toluamide) can reduce number of bites and protect also from the other vector-borne diseases like malaria or dengue. Education concerning kala-azar risk and ways of the disease prevention is a needed for tourists and the other travelers.

Opis:
Phenolic compounds form one of the main classes of secondary metabolites. They display a large range of structures and are responsible for the major organoleptic characteristics of plant-derived foods and beverages, particularly color and taste properties. They also contribute to the nutritional qualities of fruits and vegetables. Among these compounds, flavonoids constitute one of the most prevailing groups among plant phenolics. Owing to their importance in food organoleptic properties and human health, a better understanding of their structures and biological activities indicates their potentials as therapeutic agents and also for predicting and controlling food quality. Due to the variety of pharmacological activities in the mammalian body, flavonoids are more correctly referred as “nutraceuticals”.
Związki fenolowe są jedną z głównych grup metabolitów wtórnych. Mogą mieć bardzo różną strukturę i są odpowiedzialne za większość cech organoleptycznych żywności pochodzenia roślinnego i napojów, szczególnie za ich właściwości kolorystyczne i smakowe. Podwyższają także wartości odżywcze owoców i warzyw. Flawonoidy są jedną z największych grup fenoli roślinnych. Lepsze zrozumienie budowy i właściwości biologicznych tych związków może wykazać ich potencjał jako związków leczniczych, a także mających znaczenie w jakości żywności. Ze względu na różnorodność działań farmakologicznych w organizmach ssaków, flawonoidy powinno się nazywać „nutraceutykami”.

Opis:
Germination responses of Galium cracoviense Ehrend. (Rubiaceae), a narrow endemic species from southern Poland, were tested in light and dark conditions at three constant temperatures (5, 10, or 22°C), before and after cold-wet stratification. Additionally, seeds were germinated under different calcium carbonate (CaCO3) concentrations (1, 5, 10, 15, 20, or 25 mM/L CaCO3) at 22°C in light. The high germination capacity of seeds incubated at different temperatures, shortly after collection, already suggested the absence of dormancy in this species. Thus, the seeds are ready to germinate immediately in the field when water resources are available and the temperature is adequate. Light was a significant factor for G. cracoviense; more seeds germinated in light than in darkness at all temperatures tested. Cold stratification decreased germination especially at higher temperatures. The light requirement for G. cracoviense germination ensures their successful germination on or near the soil surface, and in cracks and crevices in limestone, when temperature and edaphic conditions are favourable. Seeds of this species show temperature enforced dormancy throughout the winter. Germination was significantly affected by calcium carbonate. Non-germinated seeds germinated well after being transferred from higher CaCO3 concentrations to distilled water. The results indicate that the seeds of this species can endure CaCO3 stress without losing their viability and start germination once CaCO3 concentration is reduced. It can be concluded that the seeds of this species require lower Ca2+ ion concentration, moderate temperatures and the presence of light to germinate.

Opis:
Aedes mosquitoes, mainly Aedes aegypti and Aedes albopictus, are the primary and secondary vectors of dengue viruses in Indonesia, with transmission occurring by sucking blood. The density of the vectors is influenced by season and rainfall, but limited by altitude. The aim of the study is to describe the density and distribution of dengue vectors during the dry season based on the altitudes of recent dengue cases in five regencies of Central Java Province, Indonesia. Mosquito larvae and pupae were collected from the indoor and outdoor water containers from 253 houses within 50 m of houses occupied by a dengue patient. A considerable dengue vector population was found in all localities and altitudes based on the Aedes indices: an HI of 41.7% (15.0–70.6), CI of 33.6% (8.1–69.6) and BI of 57.1 (15.0–94.1). The highest indices were found in the highest altitude settlement; as the most common larval habitat in this village was a large-sized cement tank, larvivorous fish can act as effective predators in this case. This finding indicates an expansion of the dengue problem from low to high altitudes, causing a high potential for dengue transmission in all of the localities.

Opis:
The Cecilian pine (Pinus ceciliae) is endemic to Balearic islands (Spain). It is a small taxon, some- times treated as synonym of Aleppo pine (P. halepensis), to which is closely related, differing mainly with dense crown shape and upright branches. The other characteristics, which differ between P. ceciliae and P. halepensis concern the cone scale and needle length only. We examined biometrically needles of Cecilian pine from Mallorca (5 tress) and Menorca (9 trees) islands, and compared them to Aleppo pine populations rep- resented by 30 trees from each island. Each tree was represented by 5 needles, and they were studied with respect to 17 morphological and anatomical characteristics. We detected that needles of the Cecilian pine were smaller, but only when compared to the Aleppo pine from the same island. In general, this difference was also observed in the number of resin canals, number of stomata and stomatal rows. Interestingly, the proportions of the needle dimensions pattern were similar in both taxa. In conclusion we stated the results support the taxonomic rank of Cecilian pine as a variety, Pinus halepensis var. ceciliae (Llorens & L.Llorens) L.Llorens, Fl. Països Catalans, 1: 197 (1984)

Opis:
Galium sect. Leptogalium Lange in NE Europe is represented by few, local endemic species which occur in the area covered by the continental ice sheet in the Pleistocene period. They are: G. cracoviense Ehrend. in S Poland, G. oelandicum (Sterner & Hyl.) Ehrend. in SE Sweden and G. sudeticum Tausch in SW Poland and N Czech Republic. 55 individuals from five populations of these species were analysed using AFLP markers. A total of 193 AFLP bands were detected using three combinations of primers; out of them 159 proved polymorphic (82.4%). The lowest values of Shannon's index and Nei's gene diversity were noted for G. oelandicum and the highest ones for G. sudeticum. The results indicate a relatively high level of genetic variability in each of endemic species in spite of that the studied species occupy very small areas and are represented by a low number of populations. We conclude that additional, demographic and genetic studies are necessary to monitor potential decrease of populations' size resulting mainly from the mechanical destruction of plants and their habitats caused by intense tourism or other human activities (as agriculture, e.g. grazing).

Opis:
In this study, we compared the compositions, antimicrobial and potential antioxidant activities of essential oils of two Thymus endemic, wild-growing species – T. malyi Ronninger and T. lykae Degen et Jav. No information about its composition and biological activities of oils has been reported to the present day. Forty three compounds were identified from T. malyi and major component was α-pinene (26.4%). In the case of T. lykae, forty four compounds were identified, with geranyl acetate (35.1%) as the main component. Antioxidant activities of the oils were evaluated using DPPH assay. The antimicrobial effect of essential oils were tested against Gram-negative, Gram-positive bacteria, and two fungi. Results indicated higher antibacterial activity of the essential oils of T. lykae in comparison with T. malyi, while for antifungal activity, it was reverse. The essential oils from T. malyi and T. lykae possess antioxidant and antimicrobial activities and could be used as a potential source of natural antioxidants for the food industry.

Opis:
The study presents the results of the analysis of development stages of Luronium natans (L.) Raf. depending on water conditions (pH, light, total nitrogen, total phosphorus, organic carbon) in 21 populations in north-western Poland. The fractions of seedlings, juvenile, mature and generative stems, as well as the course of phenological phenomena were determined. Seedlings are sparse and can be found from May to July. Most of them occur in waters ranging from slightly acid to neutral (pH 6.0-7.0) with TP concentrations of 10-20 µg dm-3, TN concentrations < 1.0 mg dm-3 and DOC concentrations of 3.5-5.0 mg dm-3, on a mineral (5-10% OC) and fairly well lit (31-40% PAR) substrate. The generative phase lasts from May to October. The flowering period is between August and mid-September. Only 35.2±9.4% of flowering stems produce fruits. The plant flowers abundantly in waters with total nitrogen concentrations > 1.2 mg dm-3, that is above the level of TN concentrations most favourable to seedlings and both juvenile and mature individuals. TP and DOC concentrations, and light intensity (PAR) do not influence the size of the generative stems fraction in populations. However, sediment structure is of importance in this respect: about 62.9% of stems flower and fruit on a mineral substrate (< 1% OC), whereas only 17.4% do so on an organic one. The results of this study may be useful in the conservation of this endangered European endemic species.

Opis:
New nuclear microsatellite markers (SSRs) were developed for Aesculus hippocastanum, a relict tree species from the Balkan Peninsula. The development of microsatellites was done using the Illumina MiSeq PE300 platform. Out of a set of 500 SSRs designed, a subset of 13 loci was tested using 290 individuals from seven natural populations. Twelve species-specific loci were polymorphic. The number of alleles per locus ranged from 2 to 17 and expected heterozygosity from 0.089 to 0.800 with a mean value of 0.484. The population of Kalampaka had the lowest value of allelic richness (2.63) and gene diversity in comparison to the remaining populations. STRUCTURE analysis confirmed isolation of population Mariolata from the southern edge of the species range and genetic similarity among populations from the Pindos Mts. Additionally, the utility of new SSRs in 29 individuals from nine other Aesculus taxa was tested. Eleven markers gave polymorphic products for all tested species. For 24 individuals, a high-quality product was obtained for each marker. Results confirmed the utility of specific markers for future population genetics studies.
