EVOLUTION OF KNOWLEDGE ON THE ROTATORIA A ND ENTOMOSTRACA OF LAKE GENEVA

There is much knowledge about the Rotatoria and Entomostraca of Lake G eneva (Lake Leman) and it is increasing continuously. However, there h as been little new information developped about the Ostracods and Harp acticoids since 1922 and 1966, respectively. The decrease in the numbe r of taxonomists, a lack of recent studies concerning some ecosystem c ompartments and functionnal components of the food web, specialized re search on narrow topics; and a deficiency in the education of students entering the field in ecology, ethology and taxonomy, all may lead to the lack of understanding of whole-lake Geneva ecosystem.
