Balea Perversa (L.), Un Escargot Peu Courant Et En Raréfaction Photo Pierre-Olivier COCHARD
Balea perversa (L.), un escargot peu courant et en raréfaction Photo Pierre-Olivier COCHARD Description de l’espèce Balea perversa (LINNAEUS, 1758) est un escargot terrestre de taille modeste, 8 à 10 mm de long pour 2,2 mm de large (KERNEY & CAMERON, 1999). Il fait partie de la famille des Clausiliidae. Les Clausiliidae se reconnaissent à leurs coquilles beaucoup plus longues que larges, généralement fusiformes, et leur enroulement sénestre (enroulement vers la gauche), phénomène très peu courant chez les mollusques. Cette famille est très diversifiée dans l’Est de l’Europe, les zones de montagnes en France, et n’est plus représentée dans l’Ouest de la France que par quelques espèces. En Normandie, environ 5 espèces sont actuellement connues, une ou deux autres signalées Photo Pierre-Olivier COCHARD Contrefort de Torigni 48 L’Argiope n°50 anciennement. La détermination du genre Clausilia, le genre le plus distribué dans la région, est un véritable casse-tête. Si tous les autres Clausiliidae de la Manche ont une coquille fusiforme, qui a son tour le plus large un peu au-dessous du milieu, B. perversa est une exception. Sa coquille est étroitement conique (sa partie la plus large se situe à la base). Autres exceptions, l’ouverture (la « bouche ») est sans dents (les Clausilia et Macrogastra en ont plusieurs), l’intérieur de la coquille ne présente pas de clausilium, sorte de lame calcaire en forme de cuillière. Enfin précision importante : l’épithète spécifique ne sous-entend rien d’autre de pervers chez cette espèce, que sa particularité inhabituelle d’être enroulée vers la gauche. -

Abstract Background: Among metazoans, retention of functional diet-derived chloroplasts (kleptoplasty) is known only from the sea slug taxon Sacoglossa (Gastropoda: Opisthobranchia). Intracellular maintenance of plastids in the slug's digestive epithelium has long attracted interest given its implications for understanding the evolution of endosymbiosis. However, photosynthetic ability varies widely among sacoglossans; some species have no plastid retention while others survive for months solely on photosynthesis. We present a molecular phylogenetic hypothesis for the Sacoglossa and a survey of kleptoplasty from representatives of all major clades. We sought to quantify variation in photosynthetic ability among lineages, identify phylogenetic origins of plastid retention, and assess whether kleptoplasty was a key character in the radiation of the Sacoglossa. -

For this purpose, the material collected from the area between the years 2005 and 2009, within the framework of different projects, was investigated. The investigation of the material taken from various biotopes ranging at depths between 0 and 100 m resulted in identification of 286 mollusc species and 27542 specimens belonging to them. Among the encountered species, Vitreolina cf. perminima (Jeffreys, 1883) is new record for the Turkish molluscan fauna and 18 species are being new records for the Turkish Levantine coast. A checklist of Iskenderun mollusc fauna is given based on the present study and the studies carried out beforehand, and a total of 424 moluscan species are known to be distributed in Iskenderun Bay.

Page 1/19 Abstract Background Heterobranchia is a diverse clade of marine, freshwater, and terrestrial gastropod molluscs. It includes such disparate taxa as nudibranchs, sea hares, bubble snails, pulmonate land snails and slugs, and a number of (mostly small-bodied) poorly known snails and slugs collectively referred to as the “lower heterobranchs.” Evolutionary relationships within Heterobranchia have been challenging to resolve and the group has been subject to frequent and signicant taxonomic revision. Mitochondrial (mt) genomes can be a useful molecular marker for phylogenetics but, to date, sequences have been available for only a relatively small subset of Heterobranchia. Results To assess the utility of mitochondrial genomes for resolving evolutionary relationships within this clade, eleven new mt genomes were sequenced including representatives of several groups of “lower heterobranchs.” Maximum likelihood analyses of concatenated matrices of the thirteen protein coding genes found weak support for most higher-level relationships even after several taxa with extremely high rates of evolution were excluded. -
Environmental Heterogeneity and Benthic Macroinvertebrate Guilds in Italian Lagoons Alberto Basset, Nicola Galuppo & Letizia Sabetta

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.
