“…In January 2008 we found salinity to be more similar to historical summer values, with values above 50. Increasing salinity is considered as a limiting factor for species diversity (Filippov and Komendantov, 1996), and often some groups of Mollusca are favoured (Vieira and Amat, 1997). As a matter of fact, we found Mollusca to be the dominant taxon in Karavasta.…”

Karavasta is the widest and most important lagoon in Albania. This study aimed to assess the ecological quality status of the lagoon, acquire knowledge of a natural environment which might be exploited for aquaculture, and give management hints on the basis of anthropogenic impact and ecological conditions. A sampling campaign was carried out in 2008: at six stations, benthic fauna, water and sediment parameters were considered. Statistical analyses were carried out through multivariate procedures (PCA, classification clustering, SIMPER, RDA, DISTLM, PERMANOVA). Ecological quality was assessed through the AZTI Marine Biotic Index (AMBI), the multivariate AMBI (M-AMBI) and the Benthic Index based on Taxonomic Sufficiency (BITS). Sediment characteristics (percent organic matter, %OM; redox potential discontinuity layer depth, RPDL; particle size composition) and salinity represented contributory influences on lagoon communities. It was possible to distinguish and characterise a confined area, and benthic communities, from a marine-influenced area and its biota. The number of species was quite low when compared with other open Adriatic lagoons. ACCEPTED MANUSCRIPT 2The M-AMBI and BITS classifications gave quite similar results, which seemed consistent with the ecological conditions of the lagoon, that is a distinction in the ecological quality between the seaward and landward stations, with higher ecological quality (EcoQ) at the seaward stations. Given the pressures and the ecological condition of Karavasta, an intensification of aquaculture activities must be considered with caution, since the lagoon seems at significant risk of serious hypereutrophication. This situation is made worse by the limited water exchange with the marine environment due to the irregular dredging of the communication channels.

“…Their abundance and diversity are also important in the lower salinity ponds of solar saltworks (e.g. Britton and Johnson 1987, Evagelopoulos et al 2008, Pavlova et al 1998, Vieira and Amat 1996), where the habitat is considered to be essentially lagoonal. The response of molluscan communities to the environmental stress gradients has been extensively studied in coastal lagoons (e.g.…”

BackgroundThis paper describes an occurence dataset, also including numerical abundance and biomass data, pertaining to the macrobenthic molluscan assemblages from a marine - lagoonal environmental transition. The study system was the soft-substrate benthoscape of the area of the Kalloni solar saltworks (Lesvos Island, Greece). Specifically, the study area extended from the infralittoral zone of the inner Kalloni Gulf (marine habitat) to the bottoms of the first two evaporation ponds of the Kalloni solar saltworks (lagoonal habitat). Bottom sediment samples (3 replicates) were collected with a Van Veen grab sampler (0.1 m2) at four sampling sites, along a 1.5 km long line transect that spanned the marine - lagoonal environmental transition. A total of four surveys were carried out seasonally in 2004. A total of 39,345 molluscan individuals were sorted out of the sediment samples and were identified to 71 species, belonging to the Gastropoda (36), Bivalvia (34) and Scaphopoda (1) classes. Numerical abundance and wet biomass (with shells) data are included in the dataset.New informationThe dataset described in the present paper partially fills a significant gap in the scientific literature: Because ecological research of coastal lagoons has seldom explicitly considered the marine - lagoonal habitats interface, there are no openly accessible datasets pertaining to the particular structural component of the transitional waters benthoscapes of the Mediterranean Sea. Such datasets could prove valuable in the research of the structure and functioning of transitional waters benthoscapes. The present dataset is available as a supplementary file (Suppl. material 1) and can also be accessed at http://ipt.medobis.eu/resource?r=kalloni_saltworks_phd.

“…Due to the richness of this zoological group, numerous studies dealt with macrofaunal communities in different Mediterranean areas (Vieira and Amat, 1997;Pavlova et al, 1998;Zammouri-Langar et al, 2001;Ayari and Afli, 2003). Molluscs are among the dominant and most important components of the benthic macrofauna (Barnes, 1980;Guellorget and Perthuisot, 1992).…”

Hammamet Marina is the most important touristic port in the Gulf of Hammamet (Tunisia). The present work is a contribution to the knowledge of the functional diversity and structure of the malacofauna community in this area. Three different stations (A, B and C) within the port were sampled seasonally for a year (2005)(2006). The mollusc assemblage studied was represented by 14 species (in totally 2669 ind. were found). Among the four mollusc classes recorded, bivalves were the best represented (73.76% of the total number species), followed by gastropods (22.02%), cephalopods (2.42%) and polyplacophores (1.80%). Atlanto-Mediterranean (42.85%) and Endemic Mediterranean (39.28%) taxa prevailed in the community, followed by Indo-Pacific (7.14%) and cosmopolitan species (3.57%). A clear spatial zonation was distinguished. The station B hosted the highest abundance of gastropods (309±19.92 ind. m -2 ) and a species richness of 6±0.40. The station station A hosted the most equilibrated trophic structure, with a higher bivalve abundance (1378±99.23 ind. m -2) and a species richness of 6±0.1. Station C, located close to the mooring boats, presented the lowest abundance (230±17.47 individuals m -2 ) and the most affected assemblage. This station seemed to be affected by the higher anthropogenic pressure assessed compared to the other two stations, mainly oil pollution, due to the large quantities of hydrocarbon discharged from the boats.
