Sauro 4, Livorno, Italy *Corresponding author: e-mail: [email protected] The present study assesses the spatial and temporal distribution of motile invertebrates in Posidonia oceanica meadows located off the coast of Tuscany, in the northwestern Mediterranean Sea. A hierarchical sampling design was used to evaluate changes in composition and abundance of assemblages in relation to depth and to different periods over one year. A total of 136 taxa were determined, among them 34 Mollusca, 94 Arthropoda, 5 Annelida and 1 Echinodermata. Results of both multivariate and univariate analyses showed that the macro-invertebrate assemblage structure varied along a depth gradient but this pattern was not consistent in the two study periods. Results suggest that temporal and spatial differences in the structure of P. oceanica meadows are key driv- ers in determining the structure of associated macro-invertebrate assemblages, as values of richness and abundance decreased with a decrease in leaf length and shoot density.

  • Early Ontogeny and Palaeoecology of the Mid−Miocene Rissoid Gastropods of the Central Paratethys
    Early ontogeny and palaeoecology of the Mid−Miocene rissoid gastropods of the Central Paratethys THORSTEN KOWALKE and MATHIAS HARZHAUSER Kowalke, T. and Harzhauser, M. 2004. Early ontogeny and palaeoecology of the Mid−Miocene rissoid gastropods of the Central Paratethys. Acta Palaeontologica Polonica 49 (1): 111–134. 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 de− scribed. 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 mor− phology 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 assem− blages, Mohrensterniinae predominate the Early Sarmatian faunas. We hypothesize that this take−over by the Mohren− sterniinae 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.

A seasonal sampling procedure was performed in the area from a variety of biotops in 0-0.5 and 5m depths at 4 stations between July 2007 and May 2008. A total of 11 species and 16823 specimens belonging to Bivalvia; 15 species and 5482 specimens belonging to Gastropoda and 1 species and 1 specimens belonging to Polyplacophora classes were encountered during the study. The presence of the cosmopolitan Bivalve, Pholas dactylus Linnaeus, 1758 was remarked for the first time in this study. Also, in this context, a list of Mollusca fauna of the Black Sea coasts of Turkey is compiled based on various studies carried out in Turkish coasts of the Black Sea.

  • Study of Enviromental Indicators of the Narta Lagoon (Albania)
    Muzeul Olteniei Craiova. Oltenia. Studii i comunicri. tiinele Naturii. Tom. 26, No. 2/2010 ISSN 1454-6914 STUDY OF ENVIROMENTAL INDICATORS OF THE NARTA LAGOON (ALBANIA) MANKOLLI Hysen Abstract. This study was designed to provide data for mollusc species living in the Lagoon of Narta, their distribution by habitat type within the lagoon and to assess the state of its mollusc populations. The fauna of the lagoon is a very important part of the lagoon ecosystems. In these ecosystems cockle are the main ingredients of zoobenthos biomass. They are very important elements of the food chains playing a major role in the functioning of these ecosystems. The study of the fauna of the Lagoon Narta presents interest not only in the context of the lagoon research in our country, but also due to the fact that this lagoon is one of the most important lagoons of the Albanian coast, with a great value of biodiversity, the recognition of which should be much more profound and complex. According to the study conducted in the Lagoon of Narta, we found 24 mollusc species, 15 of them belonging to gastropods and 9 to bivalve. The statistical estimates of the population characteristic for the lagoon fauna (density, constant, frequency) show that the distribution of the cockle within Narta Lagoon depends on the communication with the sea, the presence of fresh water, the water level and scale of euthrophism.

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.

    Alma Mater Studiorum – Università di Bologna DOTTORATO DI RICERCA IN SCIENZE DELLA TERRA DELLA VITA E DELL’AMBIENTE Ciclo XXXI Settore concorsuale: 04/A2 Settore Scientifico disciplinare: GEO/01 Stratigraphic paleobiology of late Quaternary mollusk assemblages from the Po Plain-Adriatic Sea system Presentata da: Michele Azzarone Coordinatore Dottorato: Supervisore: Prof. Giulio Viola Dott.Daniele Scarponi Esame Finale anno 2019 Abstract Stratigraphic paleobiology - a relatively new approach for investigating fossiliferous sedimentary successions - is rooted on the assumption that the fossil record cannot be read at face value, being controlled not only by biotic, but also by sedimentary processes that control deposition and erosion of sediments. By applying the stratigraphic paleobiology tenets, this Ph.D. project focused on acquisition and analyses of macrofossils data to assess the response of late Quaternary ecosystems to environmental changes and enhance stratigraphic interpretations of fossiliferous successions. A primary activity of my Ph.D. research involved assembling a macrobenthic dataset from the latest Pleistocene glacial succession of the near-Mid Adriatic Deep (Central Adriatic, Italy). This dataset once combined with its counterpart from the Po coastal plain (Holocene), will offer a unique perspective on mollusk faunas and their dynamics during the current glacial-interglacial cycle. This thesis includes four papers. The first one assessed the quality and resolution of the macrofossil record from transgressive Holocene deposits of Po plain (Italy). The second paper focused on the Holocene fossil record of the Po coastal plain to evaluate the response of trematode parasites to high-frequency sea-level oscillations. The third study investigated distribution of last occurrences of macrobenthic species along a down-dip transect in the Po coastal plain and evaluate potential effects of sequence stratigraphic architecture on mass extinction pattern.

In this paper we review the Caenogastropoda of the Zanclean lower Pliocene assemblage of Le Pigeon Blanc, Loire-Atlantique department, which we consider the ‘type’ locality for Assemblage III of Van Dingenen et al. (2015). Ninety-one species are recorded, of which 17 are new: Bittium lozoueti nov. sp., Bittium gliberti nov. sp., Tympanotonos redoniensis nov. sp., Oligodia palumbina nov. sp., Cochlis robbai nov. sp., Cochlis pedrialii nov. sp., Payraudeautia pigeonblancensis nov. sp., Alvania calasi nov. sp., Alvania dissensia nov. sp., Alvania merlei nov. sp., Alvania zbyszewskii nov. sp., Crisilla ariejansseni nov. sp., Rissoa pouweri nov. sp., Caecum aartseni nov. sp., Nystia guillotini nov. sp., Aclis pacaudi nov. sp., Niso dollfusi nov. sp. This includes the first European Neogene record for the genus Tympanotonos. Macromphalina bouryi (de Morgan, 1915) is a secondary homonym of Macromphalina bouryi (Dautzenberg, 1912) and renamed Macromphalina massicardi nom.
