Time and spatial dynamics of Mediterranean lagoon macrobenthos during an exceptionally prolonged intver, resulted in the total disappearance of the macrobenthos at depths of more than 5 m. Only one community that had adapted well to the brackish conditions had survived on the thin coastal fringe. In 1990, abnormal drought conditions resulted in the interruption of freshwater inputs for a period of

A comparative study of the zoobenthos of eight land—water interfaces (Lake of Geneva)l interfaces (concrete walls, cracked walls, embankments) and five natural interfaces (stony shores, stony shores below a riparian forest, reed-belts, clayey banks and sandy shores) were chosen, according to their qualitative or quantitative importance in Swiss lakes..Macroinvertebrate density, dive

Diel patterns of feeding and vertical migration in daphnids and diaptomids during the clear water phhythms. Moreover, most of the information on . diel feeding and migratory rhythms is based on low sampling frequencies. The kinetics and the degree of coupling of these processes are thus only roughly known. Here, we present a study conducted on a diel cycle in Lake Geneva to establish the temporal

Modification of migratory behavior of planktonic Crustacea in the presence of a bloom of , (Cyanobace goal of the study was to specify the role of the exogenous factors, especially the effects of Cyanobacteria bloom, and also those of photoreceptors of the Crustaceans..We used a transparent column (3 meter high and with a 0,25 m base diameter) in a controled enclosure. Organisms were subjected to

Spatial patterns of planktonic microcrustaceans in a small shallow lakeburb, France) during the summer..At all scales of sampling, the distribution was patchy. However, the variations between sampling units were smallest when considering the smallest sampling grid (30 sampling units in a 0.5 ha area). Positive correlations between densities of most taxa were observed a

Diel changes in the alkaline phosphatase activity of bacteria and phytoplankton in the hypereutrophias predominantly algal. The high concentrations in SRP (soluble reactive phosphorus) would indicate that orthophosphates were not bioavailable. The reverse (. availability to phytoplankton) would have resulted in undetectable levels of P-PO.. due to the massive proliferation of algae in Villerest reservoir.
