  • 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.

  • Trophic and Biotic Interactions in Laminaria Digitata Beds: Which Factors Could Influence the Persistence of Marine Kelp Forests in Northern Brittany?

The general trophic structure did not vary between the two sites, with a wide diversity of filter-feeders and predators, and only 14% of grazers. The results of stable isotope analyses allow drawing a simplified model for the food web associated to L. digitata beds. Kelp-derived organic matter is channeled into two distinct trophic pathways, the particle feeding-based and the grazing-based, which are coupled with higher trophic levels. The L. digitata detritic pathway contributes most to the diet of filter-feeders inhabiting sheltered sites.

Therefore, seamounts can only exist where there are sea beds more than one kilo- metre deep, or, which is one and the same thing, over 60%–62% of the land surface1. There are also thousands of smaller elevations that tend to be known as abyssal hills (when they are less than 500 metres) or mounds (between 500 and 1,000 metres). Whether in isolation or as part of extensive ranges, there are possibly more than 100,000 sea- mounts around the world2. At present, close to 30,000 of them have been identified, of which around 1,000 can be found in the Atlantic Ocean3, where in addition the largest range in the world can be found; the Mid–Atlantic Ridge, which stretches from Iceland to the Antarctic.

This report is the fifth part of the monograph of the rich assemblage of gastropods occurring in the so-called Pleurotoma Clays of Middle Miocene (Badenian) age, exposed in the environs of Korytnica in the Holy Cross Mountains, Central Poland. Besides 73 species, described earlier, the report contains descriptions of 52 species omitted from the earlier parts; of which, 50 were not recorded previously from Korytnica. Five species are established as new: Cocculina (Dallia) unica sp.nov., Turritella (Peyrotia) circumcisa sp.nov., Caecum korytnicense sp.nov., Morula valdemari sp.nov., and Ocinebrina recognita sp.nov. A new name, Megalomphalus palazzii nom.nov. is proposed for Narica depressa BOETTGER, 1907 [=Megalomphalus depressus (BOETTGER, 1907)], which is a homonym of Megalomphalus depressus (SEGUENZA, 1876).

The shells of most species are cap-shaped and limpet-like with radial ribs, but others have depressed, shield-like shells. A characteristic of this family is that there is an anal opening in the shell – a feature lacking in the true limpets and the false limpets. In the typical case the opening is at the apex and this may be circular, oval, elongated or keyhole-shaped, giving rise to the popular family name. In some species the apical opening is replaced by an anterior marginal slit or is absent altogether. In species with shield-shaped shells, there is a shallow posterior marginal indentation. An operculum is absent. Intertidal and shallow rocky habitats, where they are found attached to rocks. Generally described as herbivorous, feeding on algae. However, three species of Diodora described in Siddiqui et al, 2007, as well as Scutus, are said to feed on sponges that grow on the underside of rocks.

  • Exotic Molluscs in the Mediterranean Basin: Current Status and Perspectives
    Oceanography and Marine Biology: an Annual Review 2003, 41, 237–277 © R.N. Gibson and R.J.A. Atkinson, Editors Taylor & Francis EXOTIC MOLLUSCS IN THE MEDITERRANEAN BASIN: CURRENT STATUS AND PERSPECTIVES SERGE GOFAS1 & ARGYRO ZENETOS2 1Departamento de Biologia animal, Facultad de Ciencias – E-29071 Málaga, Spain e-mail: [email protected] 2National Centre for Marine Research, P.O. Box 712, Mavro Lithari, GR-19013 Anavissos, Greece e-mail: [email protected] Abstract An updated synthesis is presented for the records of introduced Mollusca in the Mediterranean basin. The rationale for taking molluscan records as significant is discussed. The Mediterranean Sea, with some 1800 native species of Mollusca, currently houses 139 exotic species, of which 85 form established populations, 52 are aliens recorded once or twice, and two are questionable. Ten species (the gastropods Cerithium scabridum, Rhinoclavis kochi, Strom- bus persicus and Bursatella leachi and the bivalves Pinctada radiata and Brachidontes pharao- nis in the eastern Mediterranean, the gastropod Rapana venosa and the bivalves Anadara inaequivalvis, Musculista senhousia, and Xenostrobus securis in the northern Adriatic and the western Mediterranean lagoons) are locally invasive. The bulk of the introduced species (118 species, of which 70 are established, 46 aliens, and two questionable) are species of Indo–Pacific origin found mainly in the eastern basin of the Mediterranean. Among these species, some which live in the Suez Canal are most likely to have spread by their own means through this waterway (these are the “lessepsian immigrants” in the most restricted sense). For other species, the intervention of transport by ship hulls or ballast water can be suspected.
