Marine Snails of the Genus Phorcus: Biology and Ecology of Sentinel Species for Human Impacts on the Rocky Shores
DOI: 10.5772/intechopen.71614 Provisional chapter Chapter 7 Marine Snails of the Genus Phorcus: Biology and MarineEcology Snails of Sentinel of the Species Genus Phorcusfor Human: Biology Impacts and on the EcologyRocky Shores of Sentinel Species for Human Impacts on the Rocky Shores Ricardo Sousa, João Delgado, José A. González, Mafalda Freitas and Paulo Henriques Ricardo Sousa, João Delgado, José A. González, MafaldaAdditional information Freitas and is available Paulo at Henriques the end of the chapter Additional information is available at the end of the chapter http://dx.doi.org/10.5772/intechopen.71614 Abstract In this review article, the authors explore a broad spectrum of subjects associated to marine snails of the genus Phorcus Risso, 1826, namely, distribution, habitat, behaviour and life history traits, and the consequences of anthropological impacts, such as fisheries, pollution, and climate changes, on these species. This work focuses on discussing the ecological importance of these sentinel species and their interactions in the rocky shores as well as the anthropogenic impacts to which they are subjected. One of the main anthro- pogenic stresses that affect Phorcus species is fisheries. Topshell harvesting is recognized as occurring since prehistoric times and has evolved through time from a subsistence to commercial exploitation level. However, there is a gap of information concerning these species that hinders stock assessment and management required for sustainable exploi- tation. Additionally, these keystone species are useful tools in assessing coastal habitat quality, due to their eco-biological features. Contamination of these species with heavy metals carries serious risk for animal and human health due to their potential of biomag- nification in the food chain. -

Lecce-Monteroni 73100 Lecce RESEARCH ARTICLE ITALY Abstract 1 - Lagoons are ecotones between freshwater, marine and terrestrial biotopes, characterized by internal ecosystem heterogeneity, due to patchy spatial and temporal distribution of biotic and abiotic components, and inter-ecosystem heterogeneity, due to the various terrestrial-freshwater and freshwater-marine interfaces. 2 - Here, we carried out an analysis of environmental heterogeneity and benthic macro-invertebrate guilds in a sample of 26 Italian lagoons based on literature produced over a 25 year period.. 3 - In all, 944 taxonomic units, belonging to 13 phyla, 106 orders and 343 families, were recorded. Most species had a very restricted geographic distribution range. 75% of the macroinvertebrate taxa were observed in less than three of the twenty-six lagoons considered. 4 - Similarity among macroinvertebrate guilds in lagoon ecosystems was remarkably low, ranging from 10.5%±7.5% to 34.2%±14.4% depending on the level of taxonomic resolution. 5 - Taxonomic heterogeneity was due to both differences in species richness and to differences in species composition: width of seaward outlet, lagoon surface area and water salinity were the most important factors affecting species richness, together accounting for up to 75% of observed inter-lagoon heterogeneity, while distance between lagoons was the most significant factor affecting similarity of species composition. -
Data About the Molluscs of Adria
Acta Biologica Szeged 13, (3—4), pp. 137—112 (1967) DATA ABOUT THE MOLLUSCS OF ADRIA A. HORVÁTH—K. BABA Institute for Systematic Zoology of the Attila József University Szeged and Institute for Zoology of the Teacher's Training College Szeged (Received October 31, 1967) The data presented in this paper were collected by K. Bába, according to the points of view of a previous discussion with A. Horváth, in August 1966. Our purpose was to study the qualitative and quantitative division of molluscs in the littoral biotopes. The collection has taken place in two ways. (A) Cenological collection, collecting every specimen in a square area of definite size. (B) Individual collection, collecting the molluscs found during perambulating a larger area. The results of these collections are made known one by one, as follows. The numbers, written after the Latin names of species, are meaning the number of the found specimens, after them it is indicated in brackets, as well, how many of them were juvenile specimens.

Paolo Giulio Albano Coordinatore Dottorato Relatore Prof.ssa Barbara Mantovani Prof. Francesco Zaccanti Co-relatore Prof. Bruno Sabelli Esame finale anno 2011 to Ilaria and Chiara, my daughters This PhD thesis is the completion of a long path from childhood amateur conchology to scientific research. Many people were involved in this journey, but key characters are three. Luca Marini, director of “Secche di Tor Paterno” Marine Protected Area, shared the project idea of field research on molluscs and trusted me in accomplishing the task. Without his active support in finding funds for the field activities this project would have not started. It is no exaggeration saying I would not have even thought of entering the PhD without him. Bruno Sabelli, my PhD advisor, is another person who trusted me above reasonable expectations. Witness of my childhood love for shells, he has become witness of my metamorphosis to a researcher. Last, but not least, Manuela, my wife, shared my objectives and supported me every single day despite the family challenges we had to face. Many more people helped profusely. I sincerely hope not to forget anyone. Marco Oliverio, Sabrina Macchioni, Letizia Argenti and Roberto Maltini were great SCUBA diving buddies during field activities. Betulla Morello, former researcher at ISMAR-CNR in Ancona, was my guide through the previously unexplored land of non-parametric multivariate statistics. -

The Molluscan Assemblages Inhabiting the Leaves and Rhizomes of a Deep Water Posidonia Oceanica Settlement in the Central Tyrrhenian Sea
SCIENTIA MARINA 76(4) December 2012, 721-732, Barcelona (Spain) ISSN: 0214-8358 doi: 10.3989/scimar.03396.02C The molluscan assemblages inhabiting the leaves and rhizomes of a deep water Posidonia oceanica settlement in the central Tyrrhenian Sea PAOLO G. ALBANO and BRUNO SABELLI Department of Experimental Evolutionary Biology, University of Bologna, Via Selmi, 3, 40126 Bologna, Italy. E-mail: [email protected] SUMMARY: The molluscan assemblages inhabiting the leaf and rhizome layers of Posidonia oceanica were studied in a deep water (–24/26 m) settlement of a highly heterogeneous substratum on an off-shore reef in the central Tyrrhenian Sea. This is one of the few works dealing with the rhizome layer and with Posidonia oceanica that has settled on hard substrata. The leaf assemblage only had a few species, less than other assemblages at a comparable depth in the same basin. This poorness may be due to the depth, but it may also be due to the high fragmentation of the meadow. However, the high percentage of carnivores is consistent with previous observations in deep water meadows. The rhizome assemblage is highly diverse both in terms of species and feeding guilds, which could be explained by the higher affinity for low light conditions of most molluscs and the greater habitat heterogeneity. The marked differences in the two taxocoenoses and the high diversification of the rhizome assemblage evidence that they should be included in studies on the potential diversity of Posidonia oceanica meadows. Failure to consider this layer seriously affects any evaluation of the biodiversity of this habitat, which is of great conservation interest. -
New Gastropod Records for the Eastern Mediterranean Sea and One New
Manousis and Galinou-Mitsoudi Journal of Biological Research-Thessaloniki 2014, 21:20 http://www.jbiolres.com/content/21/1/20 RESEARCH Open Access New gastropod records for the Eastern Mediterranean Sea and one new alien (Emarginula decorata Deshayes, 1863) for the Mediterranean Sea from NW Aegean Sea, Greece Thanasis Manousis1† and Sofia Galinou-Mitsoudi2*† Abstract Background: The NW Aegean Sea has a complex topography, high quality waters, oligotrophic to eutrophic conditions, is connected with estuaries and wetlands, is of high ecological interest, harbours all the types of human activities and yet few researchers work on its marine biodiversity. With this study, the contribution to the knowledge of the Hellenic and Eastern Mediterranean gastropod biodiversity of the studied families is continued, and an expansion of the search in other substrates and deeper waters of the NW Aegean Sea with emphasis on the minor in size species during the period from October 2008 to January 2014. Results: Thirty seven species belonging to seven families (Cerithiopsidae, Fissurellidae, Phasianellidae, Scissurellidae, Siliquariidae, Skeneidae, and Triphoridae) were identified and their biodiversity was compared with the current checklists of marine gastropod molluscs for the Hellenic Seas based on previous surveys. In this collection of gastropods, one species (Emarginula decorata Deshayes, 1863) is a new alien for the Mediterranean Sea, 14 species are new for the Eastern Mediterranean Sea and 16 species are new for the Hellenic fauna (with the one above mentioned alien species included). The main identification characteristics and ecological information such as habitat, distribution, alien expansion paths to the NW Aegean Sea and origin of the species are given and discussed. -
