Rocky Shore Snails As Material for Projects (With a Key for Their Identification)
Field Studies, 10, (2003) 601 - 634 ROCKY SHORE SNAILS AS MATERIAL FOR PROJECTS (WITH A KEY FOR THEIR IDENTIFICATION) J. H. CROTHERS Egypt Cottage, Fair Cross, Washford, Watchet, Somerset TA23 0LY ABSTRACT Rocky sea shores are amongst the best habitats in which to carry out biological field projects. In that habitat, marine snails (prosobranchs) offer the most opportunities for individual investigations, being easy to find, to identify, to count and to measure and beng sufficiently robust to survive the experience. A key is provided for the identification of the larger species and suggestions are made for investigations to exploit selected features of individual species. INTRODUCTION Rocky sea shores offer one of the best habitats for individual or group investigations. Not only is there de facto public access (once you have got there) but also the physical factors that dominate the environment - tides (inundation versus desiccation), waves, heat, cold, light, dark, salinity etc. - change significantly over a few metres in distance. As a bonus, most of the fauna and flora lives out on the open rock surface and patterns of distribution may be clearly visible to the naked eye. Finally, they are amongst the most ‘natural’ of habitats in the British Isles; unless there has been an oil spill, rocky sea shores are unlikely to have been greatly affected by covert human activity. Some 270 species of marine snail (Phylum Mollusca, Class Gastropoda; Sub-Class Prosobranchia) live in the seas around the British Isles (Graham, 1988) and their empty shells may be found on many beaches. Most of these species are small (less than 3 mm long) or live beneath the tidemarks. -
Panpulmonata: Amphibolidae) in South-Eastern Australia
Biodiversity Data Journal 8: e54724 doi: 10.3897/BDJ.8.e54724 Research Article Genetic assessment of the variation and distribution of the species of Salinator (Panpulmonata: Amphibolidae) in south-eastern Australia Donald Colgan‡, Hugo Lumsdaine‡ ‡ The Australian Museum, Sydney, Australia Corresponding author: Donald Colgan ([email protected]) Academic editor: Cristian Altaba Received: 26 May 2020 | Accepted: 16 Sep 2020 | Published: 29 Oct 2020 Citation: Colgan D, Lumsdaine H (2020) Genetic assessment of the variation and distribution of the species of Salinator (Panpulmonata: Amphibolidae) in south-eastern Australia. Biodiversity Data Journal 8: e54724. https://doi.org/10.3897/BDJ.8.e54724 Abstract Amphibolidae is one of the most abundant families of gastropods in estuarine environments of south-eastern Australia. However, the range limits of the species of Salinator, one of the family’s two genera in the region, remain unclear partly due to uncertainty of identifications based solely on shell morphology. Insufficient data have been collected to address questions regarding the genetic variability of any of the species of Salinator. Here, DNA sequences from a segment of the cytochrome c oxidase subunit I and 28S ribosomal RNA genes were collected to investigate the distribution and variation of the three Salinator species in the region, these being S. fragilis, S. rhamphidia and S. tecta. The results demonstrate a large range extension in S. rhamphidia and suggest that S. tecta may have limited distribution in Tasmania. In contrast to previously-studied estuarine Mollusca in the south-eastern coasts of the mainland and Tasmania, S. rhamphidia has regional differentiation. There is evidence of genetic disequilibrium within S. -
Utility of H3-Genesequences for Phylogenetic Reconstruction – a Case Study of Heterobranch Gastropoda –*

W. Goethe-University, Frankfurt am Main, Germany *Paper presented to the 2nd International Workshop on Opisthobranchia, ZFMK, Bonn, Germany, September 20th to 22nd, 2006 Abstract. In the present study we assessed the utility of H3-Genesequences for phylogenetic reconstruction of the He- terobranchia (Mollusca, Gastropoda). Therefore histone H3 data were collected for 49 species including most of the ma- jor groups. The sequence alignment provided a total of 246 sites of which 105 were variable and 96 parsimony informa- tive. Twenty-four (of 82) first base positions were variable as were 78 of the third base positions but only 3 of the se- cond base positions. H3 analyses showed a high codon usage bias. The consistency index was low (0,210) and a substitution saturation was observed in the 3r d codon position. The alignment with the translation of the H3 DNA sequences to amino-acid sequences had no sites that were parsimony-informative within the Heterobranchia. Phylogenetic trees were reconstructed using maximum parsimony, maximum likelihood and Bayesian methodologies. Nodilittorina unifasciata was used as outgroup. The resolution of the deeper nodes was limited in this molecular study. The data themselves were not sufficient to clar- ify phylogenetic relationships within Heterobranchia. Neither the monophyly of the Euthyneura nor a step-by-step evo- lution by the “basal” groups was supported. -

CANCAP Project contributionNo. 126 J.J. van Aartsen & J. Goud National Museum ofNatural History, EO.

Key words: Gastropoda, Fissurellidae, Emarginula, taxonomy, Madeira. Several specimens of an Emarginula species were collected during the CANCAP-I der well of material off expedition (van Land, 1987), as as by private searching dredged the south-coast of Madeira. As these shells did not to of the well- evidently belong any known species mentioned from Madeira by Watson (1897: 286) and Nobre (1937: 67), viz. Emarginula fissura (Linne, 1758), E. huzardii Payraudeau, 1826, and E. tenera Locard, drawn Crosse 1892, our attention was to ‘Semperia paivana Crosse, 1867'. described a new which he considered be characterised genus Semperia, to by an anterior slit, just as in in in Emarginula; fully grown specimens however, contrast to Emarginula, this slit was clo- sed (or nearly so) at the anterior end. Semperia paivana, collected near Madeira, was des- ignated as the type species of this genus. Watson (1897: 286), referring to Emarginula fissura, wrote "Everywhere; very common, in every form of transition to Semperia paivana Crosse ...".

After identification of the mollusc collections from STUDY AREA these localities we have found that two gastropods species, namely Salinator fragilis (Lamarck), and Pseudonoba columen (Melvill) are new records. The first mentioned is a new record from India INDIA and the later is a new record for Gujarat as well as from India.

As a baseline for future studies that will enhance the knowledge of this fauna, we have compiled a checklist combining the existing published data with original data from a recent research. Examination of sampled material and a review of the relevant literature revealed the presence of 354 mollusc species. Twelve species have been recorded for the first time in Montenegrin waters, 7 species are of non-native origin while 14 taxa are recognized as endangered and threatened, according to the IUCN Red List and the Barcelona/Berne Conventions. A comparison of our results with those of the neighbouring seas indicates that mollusc fauna is insufficiently studied, but we should bear in mind that the number of recorded species in relation to the size of the researched area points to a rich malacofauna zone. Keywords: Marine molluscs, checklist, alien species, Montenegro, Adriatic Sea. Introduction From a geomorphologic viewpoint, the Montenegrin coast can be divided into two main Molluscs are important components of marine parts: the Bay of Boka Kotorska and the open sea. -

In this paper we review the Patellogastropoda and Vetigastropoda of the Zanclean lower Pliocene assemblage of Le Pigeon Blanc, Loire-Atlantique department, France, which we consider the ‘type’ locality for Assemblage III of Van Dingenen et al. (2015). Three patellogastropod and 28 vetigastropod species are recorded, of which eleven are new: Emarginula brebioni nov. sp., Jujubinus armatus nov. sp., Jujubinus pigeonblancensis nov. sp., Jujubinus condevicnumensis nov. sp., Jujubinus ligeriensis nov. sp., Gibbula provosti nov. sp., Gibbula milleti nov. sp., Colliculus neraudeaui nov. sp., ?Tectus columbinus nov. sp., Calliostoma namnetense nov sp. and Microgaza landreauensis nov. sp. This includes possibly the first European Pliocene record for the genus Tectus. Calliostoma tauromiliare (Sacco, 1896) is considered a junior synonym of Calliostoma baccatum (Millet, 1865). Based on the data presented here, we suggest that the average Sea Surface Temperatures off the NW French coast in the Zanclean lower Pliocene may have been warmer than they are at these latitudes today, possibly similar to those found today off the southern Portuguese coasts. -
