Evolution qualitative � long terme des rotif�res du Lac L�man
Aquatic Sciences, 1990Seventy-five species and lower taxonomic units of rotifers have been identified in Lake Geneva (= lac Leman); seven species and one form are new for the lake. When using indicators of trophic conditions, the qualitative composition of the biocenosis is still dominated by oligo-mesotrophic lake indicators, mixed with eutrophic and oligotrophic ones ...

Premier complément à l'inventaire de la biocénose planctonique du lac Léman
Swiss Journal of Hydrology, 1985New phytoplanktonic and zooplanktonic species have been observed for the first time in Lake Geneva (Lac Leman); moreover, the presence of some Rotatoria and Entomostraca has been confirmed in the lake biocenosis.

Evolution quantitative � long terme des rotif�res au cours de l'eutrophisation du Lac L�man
Aquatic Sciences, 1990Eutrophication in Lake Geneva (= Lake Leman) appears primarily as changes in chemical characteristics and plankton populations, inducing quantitative changes in the rotifer assemblages and species combinations. In the course of eutrophication, an increase of the rotifer abundance was found, together with settlement of new species and increase of ...

Premières données sur l'évolution quantitative des entomostracés planctoniques dans le lac Léman
Schweizerische Zeitschrift für Hydrologie, 1984The increasing eutrophication of lake Geneva (lake Leman) induced a more than twofold increase of the mean annual zooplankton biovolume from 1959 to 1982.

In order to determine the food preferences of young roach, gut contents of roach fry (Rutilus rutilus (L.)) were compared with the evolution of the zooplankton community in a littoral area of Lake Geneva during June and July 1985. The food of roach fry up the age of 30 d (10–15 mm standard length) was mainly small Rotifers with some Chronomid larvae ...
