Opis:
We studied the shell and penis morphology, and cytochrome oxidase subunit I (COI) gene sequences, in minute, valvatiform hydrobiid gastropods from Slovensky Kras, Slovakia. The morphology confirmed the assignment of the studied snails to the genus Hauffenia, while in the molecular tree they were placed within the Hydrobiidae, and not close to Hauffenia. The results indicate that the Slovak valvatiform hydrobiids are two taxa which presumably represent two genera: Hauffenia Pollonera, 1898 and Lobaumia Haase, 1993. More molecular data on the Austrian and Hungarian taxa are needed.

Opis:
A low diversity association made up of the lingulid Tunisiglossa almalensis Popov and Mambetov, sp. nov. and the gastropod Ptychonema agyris Ebbestad, sp. nov. is described from the Upper Member of the Almaly Formation at Kyrgyz Range, North Tien Shan, Kyrgyzstan/Kazakhstan. The specimens co−occur in dense coquinas, made up of different sized individuals, deposited in a shallow water, intertidal, and storm driven depositional environment. The lingulid shells display a completely reduced dorsal pseudointerarea typical of Glossellinae, and the smooth shell lacking fine external granulation, radial or pitted ornament, a small ventral pseudointerarea, and no dorsal median ridge place it in the hitherto monotypic Tunisiglossa known previously only from the Lower Ordovician (Tremadocian) Sanrhar Formation of Libya. It compares with Ectenoglossa sorbulakensis that is widespread in the lower to middle Caradocian Anderken Formation of Chu−Ili Range in southern Kazakhstan. Gastropods of this age have not been reported earlier in Kyrgyzstan; neither can Ptychonema be compare with any taxon in the gastropod association earlier described from the contemporary Anderken Formation in Kazakhstan. Ptychonema is otherwise commonly associated with peri−Gondwana terranes, but the Late Ordovician dispersal pattern of the genus is unknown. Overall, however, the Upper Ordovician faunas of North Tien Shan show close similarities to contemporaneous faunas of the Chu−Ili terrane, which have strong biogeographic signatures linking them to the faunas of South and North China.

Opis:
The common Early Triassic (Olenekian) gastropod Turbo rectecostatus from the upper Werfen Formation of the Alps is placed in the new genus Werfenella. Elimination of the wrong or outdated generic assignments of Late Palaeozoic and Early Mesozoic gastropods to archetypical genera such as Turbo, Trochus, or Natica (all with Recent type species) represents an important step toward understanding the evolutionary history of the gastropods across the Permian/Triassic mass−extinction event. The first appearance of Werfenella in the Olenekian, as well as the origination of other groups of gastropods, suggests an early turnover in the aftermath of the end−Permian mass extinction event. The relatively large size of Werfenella (up to 35 mm) sheds doubt on assertions that all Early Triassic gastropods are microgastropods (Lilliput effect). The new genus is placed in the caenogastropod family Purpurinidae and represents its earliest occurrence. However, a placement of Werfenella in the Archaeogastropoda (Vetigastropoda) is also possible because it resembles the paraturbinid genus Chartronella. The characteristic Werfenella rectecostata–Natiria costata gastropod association from the Werfen Formation is not found in the approximately contemporaneous Sinbad Limestone of the Moenkopi Formation (Utah, USA) nor elsewhere outside Europe. This suggests that the similarities between Olenekian gastropod faunas from the Tethys and western North America are more limited than previously thought.

Opis:
Provanna marshallisp. nov. is described from Early to Middle Miocene−age fossil hydrocarbon seep localities in the East Coast Basin, North Island, New Zealand, adding to 18 modern and three fossil species of the genus described. Modern species are well represented at hydrothermal vent sites as well as at hydrocarbon seeps and on other organic substrates in the deep sea, including sunken wood and whale falls. Described fossil Provanna species have been almost exclusively reported from hydrocarbon seep deposits, with a few reports of suspected fossil specimens of the genus from other chemosynthetic environments such as sunken wood and large vertebrate (whale and plesiosaurid) carcasses, and the oldest occurrences are dated to the Middle Cenomanian (early Late Cretaceous). The New Zealand fossil species is the most variable species of the genus described to date, and its shell microstructure is reported and found to be comparable to the fossil species Provanna antiqua and some modern species of the genus.

Opis:
We describe Gastrocopta sandbergeri sp. nov. from the Miocene brown coal deposits of the open−cast mine Bełchatów (central Poland) and identify it as conspecific with Pupa (Vertigo) suevica Sandberger, 1875 (nomen nudum) from the Miocene of Steinheim. The new name “sandbergeri” has been introduced in substitution because Sandberger’s name “suevica” has been later proposed again for a valid species Gastrocopta (Albinula) suevica by Boettger (1889). We could not use the name “minor” proposed by Miller (1900) as form of Pupa (Leucochilus) suevica because it is preoccupied by another Gastrocopta species: Bifidaria ashmuni f. minor Sterki, 1898 [= Gastrocopta ashmuni (Sterki, 1898)]. In consequence Sandberger’s Pupa (Vertigo) suevica is recognized as the senior synonym of Gastrocopta sandbergeri sp. nov. The new species is most similar to Gastrocopta nouletiana (Dupuy, 1850) but differs in having smaller and always slender shell, less convex whorls, much weaker crest on the body whorl (or even absent) and generally rather weakly developed teeth (6–7) in the aperture.

Opis:
Although the record of Paleozoic drillholes is long and extensive, evidence pertaining to the identity of the drillers is sparse. The most conclusive evidence, a driller “caught in the act”, has been documented only once (Baumiller 1990). In that example, a drillhole in the calyx of a crinoid was found directly beneath an attached platyceratid gastropod. Additional evidence for drilling by platyceratids has been circumstantial, i.e., based on the association of platyceratids with certain blastoids and crinoids, and the presence of drillholes in other crinoid and blastoid taxa. To a skeptic, the lack of congruence between drilled and platyceratidinfested crinoids and blastoids is not sufficient evidence that platyceratids were the drillers. More conclusive evidence requires examples of drillholes in taxa that are known to have been platyceratid−infested, preferably from localities where both infested specimens and drilled specimens co−occur.

A new, relatively diverse gastropod fauna is reported from the Chubut province of west−central Patagonia. The gastropod association at the “El Córdoba” fossiliferous locality (Lower Toarcian of Osta Arena Formation) consists of three new species: the eucyclid Amberleya? espinosa sp. nov. and two procerithiids Cryptaulax damboreneae sp. nov. and Cryptaulax nulloi sp. nov. Other members of the association are the ataphrid Striatoconulus sp., discohelicid Colpomphalus? sp., and an undetermined zygopleurid. Knowledge on Early Jurassic gastropods from South America and other southern continents is reviewed to show that the taxonomic composition of the El Cordoba association strongly resembles other gastropod associations of this age (even those from Europe), suggesting a wide distribution of cosmopolitan genera.

Opis:
This study analyses the composition, species richness and diversity (H’) of aquatic molluscan communities in temporary water bodies within the valley of the lower Bug River in eastern Poland. The investigations were carried out in 2007–2009 within the section of the valley located between 190th and 50th km of the river course in 50 water bodies. Relatively rich and diverse malacofauna was found in the investigated habitats: 32 snail species and 6 bivalve species. Species diversity (H’) in individual water bodies ranged from 0.44 to 3.48. About 40% of all mollusc species showed frequencies of _10%. Dominance patterns varied much among the water bodies. Mollusc abundance ranged from 20 to over 1,800 indiv./m2. Considerable species richness and diversity were found both within the active floodplain and the former one. This was probably related to the long duration of many of the investigated water bodies, as well as their periodical hydrological connectivity with permanent ones or river channel. From 9 to 12 samples should be enough to compile representative species list of molluscs inhabiting temporary water bodies, but as many as 28–40 samples would be necessary to obtain complete dataset.

Opis:
The Hettangian to earliest Sinemurian Vetigastropoda, Patellogastropoda, and Neritimorpha housed in the National Museum of Natural History of Luxembourg are studied. Most of the species comes from the Luxembourg Sandstone Formation. This deposit formed along the southern margin of the London−Brabant−Ardennes Landmass, in a region that during the earliest Jurassic constituted a seaway connecting the Paris Basin with the epicontinental seas of the Netherlands and northern Germany. The systematic analysis revealed high diversity of the studied fauna; we identified twenty−two species, eleven genera, nine families, and six superfamilies. A new genus, Meiersia gen. nov., and three new species, Anodomaria schroederi sp. nov., Meiersia disarmata sp. nov., and Spirocirrus weisi sp. nov. are described. The fauna is dominated by pleurotomarioideans representing the genera Ptychomphalus, Pleurotomaria, and Trochotoma, and by the patellogastropod genus Scurriopsis both in number of species and specimens. The neritimorph genus Neridomus is also well represented. Among the accessory taxa, Anodomaria and Spirocirrusfirst appeared in the Late Hettangian of the Luxembourg area. Most of these genera show a species radiation in the Early Jurassic and are distributed over the western European epicontinental shelf, probably favoured by an east to west marine transgression which influenced wide areas from the basins of the northern Germany to the Paris Basin through the Luxembourg seaway. The evolutionary and palaeobiogeographical data demonstrate that this radiation was already considerably advanced in the Late Hettangian. This suggests that the recovery of the gastropod diversity after the end−Triassic crisis was relatively fast in western Europe.

Opis:
Twenty−six species of Rissoidae (Caenogastropoda: Littorinimorpha: Rissooidea) are described from the Badenian and Early Sarmatian of 14 localities in Austria and the Czech Republic (Molasse Basin, Styrian Basin, Vienna Basin) and from the Badenian of Coştei (Romania). For the first time, the early ontogenetic skeletal characters of these gastropods are described. Based on these features an indirect larval development with a planktotrophic veliger could be reconstructed for all investigated Mid−Miocene species. The status of Mohrensterniinae as a subfamily of the Rissoidae is confirmed by the morphology of the low conical protoconch, consisting of a fine spirally sculptured embryonic shell and a larval shell which is smooth except for growth lines. Transitions from embryonic shells to larval shells and from larval shells to teleoconchs are slightly thickened and indistinct. Whilst representatives of the subfamily Rissoinae characterise the marine Badenian assemblages, Mohrensterniinae predominate the Early Sarmatian faunas. We hypothesize that this take−over by the Mohrensterniinae was triggered by changes in the water chemistry towards polyhaline conditions. Consequently, the shift towards hypersaline conditions in the Late Sarmatian is mirrored by the abrupt decline of the subfamily. Four new species Rissoa costeiensis (Rissoinae) from the Badenian and Mohrensternia hollabrunnensis, Mohrensternia pfaffstaettensis, and Mohrensternia waldhofensis (Mohrensterniinae) from the Early Sarmatian are introduced.

Effectiveness of several kinds of beer and molluscicides in gastropod control was tested in a 15-week experiment in an allotment garden, using plants of Callistephus chinensis. Among the total of 462 gastropods trapped during the observation period, 98.1% were slugs; the greatest number of gastropods was trapped in July, in the first week of the experiment. The most effective baits were beer Żubr (25.5% of all trapped gastropods), Mesurol SK 04 GB (14.5%) and beer Żywiec Porter (13.2%). The degree of plant damage dependend negatively on the number of trapped gastropods, suggesting a possibility of slug control in allotments by means of various kinds of baits.

Opis:
Late Frasnian–Early Famennian entomozoacean ostracod assemblages from the Płucki section in the Holy Cross Mountains were studied to establish the effect of the “Kellwasser bio−event” on the planktonic biodiversity and faunal content. The composition of ostracod assemblages changes from a moderately diverse (10 species) Entomoprimitia–Richterina– Nehdentomis–Nandania dominated “background” assemblage characterising a pre−event interval, to an Entomoprimitia−assemblage during the event interval, and finally to a Franklinella−dominated post−event assemblage in the Middle Palmatolepis triangularis conodont Zone. The Frasnian–Famennian extinction caused substantial losses among entomozoacean lineages. In the Płucki section it occurred in two closely spaced steps within the Palmatolepis linguiformis conodont Zone. The first step, at the base of the dark cephalopod limestone (Upper Kellwasser Horizon), reduced the abundance and the species diversity of entomozoaceans to only two Entomoprimitia species. The vacant niche was then filled by the new, immigrant species Entomoprimitia (Entomoprimitia) kayseri which is dominant in the Upper Kellwasser interval. All these species were lost at the second step within the Upper Kellwasser Horizon. The entomozoaceans remained virtually absent during a long time interval between the end−Frasnian crisis and the Middle Pa. triangularis Zone. They reappear as new species from refugia lineages (Franklinella, Nehdentomis) and became widespread, indicating favourable ecological conditions. Some 13 species have been identified and assigned to seven genera. Rabienella? lagowiensis sp. nov. is proposed.

The development of mangrove ecosystem has a significant impact on fishery resources, such as gastropod. This research aimed at studying the community structure of mangrove forest in Mojo village, to identifying and analyzing the composition and diversity of gastropod, and investigating the effect of mangrove community on the abundance and gastropod. The research was conducted in Mojo Village, Ulujami District, Pemalang Region from November to December 2017. Identification of species and density was conducted on mangrove species by means of line and plot transects, while the gastropod was sampled from the field then identified in the laboratory. Three sampling stations were occupied in the data collection. The data analysis was conducted for diversity indices, including heterogeneity and evenness both for mangrove and gastropod. Statistical data analysis was conducted by regression to analyze the effect of mangrove density on the abundance of gastropod. The result showed that only three mangrove species were found in Mojo village, including Rhizophora mucronata, Avicennia marina and A. officinalis. Eight gastropod species were identified from mangrove forest of Mojo village. The most dominant gastropod species was Telescopium telescopium, followed by Cerithidea cingulata. The analysis of heterogeneity index showed a low value for mangrove community and medium value for the gastropod community, ranging from 0.353 to 0.720 and 1.462 to 1.812, respectively. Statistical data analysis showed that the density of R. mucronata and A. marina had a significant effect on the abundance of gastropod specieses, including Cerithidea quadrata and Casidula nucleus, both of which had logarithmic relationship trends.

Opis:
Gastropod response to a marked carbon isotopic geochemical anomaly across the Early–Middle Frasnian transition (Palmatolepis transitans–Palmatolepis punctata conodont zones) has been analysed along the southern Laurussian shelf, mainly within the Dyminy Reef in the Holy Cross Mountains. Gastropods are represented by three reefal associations (Kowalatrochus sanctacrucensis, Euryzone kielcensis, and Grabinopsis guerichi associations), and an impoverished open−shelf Straparollus laevis assemblage. The most severe diversity crisis is connected to the disappearance of local low−energy muddy habitats, as a result of a transgressive pulse (Middlesex Event) and benthic habitat changes tied to strongly fluctuating carbon cycling; this has been observed at the highly diverse Kadzielnia−type assemblage. Fifteen taxa have been recognised in this distinctive Early Frasnian mud−mound association, including six (probably endemics), which are unknown from the Middle Frasnian. The disappearance of three relict Givetian species (Euryzone delphinuloides, Straparollus laevis, and Goniasma? zarecznyi) is also recorded. Other species probably migrated into the shallower water part of Dyminy Reef and persisted in the Middle and Late Frasnian. The Middlesex Event and the earlier major biogeochemical perturbation seem to have less serious effects for evolution of gastropods in the Polish−Moravian part of the Laurussia shelf than the catastrophic Frasnian–Famennian extinction. Two new taxa are described: Frydiella kaimi gen. et sp. nov. (Eotomariidae) and Heidelbergeria czarnieckii gen. et sp. nov. (Elasmonematidae).
