“…Summer recruits were produced by over-wintering snails and prob-ably contributed to the autumn recruitment. Evidence of late summer or autumn breeding of the young-of-theyear of its congener V. ventrosa was observed both in the laboratory and in the ¢eld (Barnes, 1994;Probst et al, 2000). Lassen & Clark (1979) reported that Atlantic V. ventrosa takes about three months to reach sexual maturity at lower temperatures and higher salinities (158C and 20 psu, respectively) than those occurring in Monolimni lagoon during summer and early autumn.…”

“…Ventrosia ventrosa, the congener of V. maritima, is a shortlived semelparous mud snail; its maximum life span varies between one and two years (Siegismund, 1982;Barnes, 1994;Drake & Arias, 1995;Probst et al, 2000). In northwestern European coastal habitats, V. ventrosa usually displays a single annual period peaking in summer (Lassen & Clark, 1979;Barnes, 1994;Probst et al, 2000), while in the south of its distribution range, at a shallow coastal lagoon in the Bay of Cadiz, south-west Spain, where water temperature seasonally varies between 8 and 24.58C and salinity between 18 and 65 psu, it reproduced throughout the year (Drake & Arias, 1995). Another congener of V. maritima, the direct-developing V. truncata (Vanetta, 1924), which is found along the Atlantic coast of northern North America, also displayed an annual life cycle in Massachusetts salt marsh pools; an annual recruitment occurred in summer (Mandracchia & Ruber, 1990).…”

“…An intense intraspe-ci¢c competition resulting from the peak abundances was possibly the prominent cause of the decline in population density of V. maritima in late autumn. Probst et al (2000) suggested that young snails of V. ventrosa emigrated from densely populated areas by £oating at the water surface. In addition, a high mortality due to low temperatures (54.58C) and salinities (51psu) possibly contributed to the decline in V. maritima density during winter.…”

“…However, some aspects of their biology and ecology, such as life history, population dynamics and productivity, have been studied only in few selected species. The directdeveloping Ventrosia ventrosa (Montagu, 1803), a typical lagoonal species and the larviparous Peringia ulvae (Pennant, 1777), a species of marine origin, are examples (Siegismund, 1982;Bachelet & Yacine-Kassab, 1987; Barnes, 1994;Drake & Arias, 1995;Probst et al, 2000). Most of these studies deal with mudsnail populations from north-western Europe and northeastern America.…”

Life cycle, population dynamics and productivity of the larviparous mudsnail species Ventrosia maritima were investigated at low salinities (0·3–6 psu) in differentiated parts of a Mediterranean lagoon (Monolimni Lagoon). Monthly samples were collected during the period from February 1998 to February 1999 in both parts of the lagoon. Ventrosia maritima displayed an annual life cycle. Recruitment occurred in summer and autumn at the outer part of the lagoon and additionally in late winter at the innermost part. A positive correlation was found between the percentages of small individuals and salinity or sediment organic matter at the outer part. Growth practically ceased in winter. The mudsnail displayed remarkable densities and an increase in growth in spring at <1 psu indicating that it is highly tolerant to extremely low salinities. Population density showed a significant seasonal variation; it increased from early summer to autumn (30,000–40,000 individuals m−2) following the summer and autumn recruitment. No significant correlation between the density of V. maritima and several examined physicochemical variables was found; a negative correlation was observed between the density of the mudsnail and that of the co-occurring polychaete Streblospio shrubsolii. Secondary production calculated by the size–frequency method gave a mean annual density (N) of 9740 ind m−2, a mean biomass (B) of 1·66 g ash-free dry weight (AFDW) m−2 y−1, a production (P) of 4·51 g m−2 y−1 and a P:B ratio of 2·72 at the outer part of the lagoon and a N of 14,570 ind m−2, a B of 3·2 g AFDW m−2 y−1, a P of 9·9 g m−2 y−1 and a P:B ratio of 3·09 at the innermost part. At the innermost part of the lagoon, where the seawater renewal rate and hydro-dynamism were lower and the sediment finer and organically richer, V. maritima displayed more recruitment pulses, a larger body size and a denser and more productive population than the one at the outer part. Our findings are compared to published data for the direct-developing congeners V. ventrosa and V. truncata.

“…Generally, the larvae settlement of many marine invertebrates on solid surfaces is influenced by the chemistry, wettability and positively by the roughness of the substrate surface, and these features depend greatly in case a natural biofilm is attached (e.g. The maximum ( *) and mean (**) shell length values are lying in the range estimated for this species by various authors in Europe: 3.5-6.2mm (FaLnioWsKi 1987, BaRnes 1994, PRoBst et al 2000, and 2.2-3.6mm (gRudemo & Johannesson 1999), respectively.…”

Rust-coloured shells of the aquatic gastropod Ventrosia ventrosa, a new record for eastern Greece, indicating presence of iron (EDAX analysis) were studied for detection of iron-encrusted photosynthetic epibionts in a Greek brackish-water thermal spring (38 °C). Microscopic analyses (LM, SEM) revealed the presence of a biofilm consisted of mostly facultative micro-epibionts, i.e. a) 5 periphytic taxa of coccal and filamentous cyanobacteria, including a taxonomically and ecologically interesting morphospecies, Xenococcus cf. pyriformis, dominated exclusively on the shell surface, and b) pennate diatoms with higher species richness (18 periphytic taxa of the genera Amphora, Brachysira, Cymbella, Diatoma, Encyonema, Navicula, Nitzschia, Pleurosigma, Synedra, Ulnaria; 5 taxa as new records for Greece), most of them emerging only after acid treatment of whole gastropod shells. The abundant diatoms thriving directly or nearby the iron-coatings (Cocconeis placentula var. euglypta and Achnanthes brevipes sensu lato) exhibited different modes of attachment ('adnate' and 'pendunculate', respectively). Two euendolithic cyanobacteria (Hyella sp. and Leptolyngbya terebrans; the former with special taxonomic interest) were also found perforating the delicate gastropod shells, with no distinct differentiation in the extent of infestation between live and dead gastropod shells. Moreover, the possible impact of these encrusted photosynthetic assemblages on V. ventrosa was investigated; statistical analysis showed that a) there is no 'drag effect', induced by the epibionts, influencing the gastropod growth (i.e. shell length), b) shell size enlargement provides a favourable space and promotes the intense fouling by both micro-epibionts and macro-epibionts (eggcapsules), and c) the detachment prevention of egg-capsules is attributed to the biofilm development.
