Abstract

Filinia terminalis kergueleniensis nov. spp. (Family Filiniidae Bartos 1959), from Lake Studer 2 is described and figured. Filinia terminalis kergueleniensis differs from the type in length of bristles and their insertion. Keratella sancta was found again; it is the third record after its discovery by Russel 1944 in New Zealand. Notholca cf. jugosa Gosse 1889 is also found in the plankton of the subantarctic lake. The new subspecies and Keratella sancta occur all year round, while Notholca cf. jugosa is sporadic. Population dynamics appear to be dependent on changes in temperature and chlorophyll content. We have estimated the relative contribution of these three species to community biomass from their numerical abundance and measured volumes. The major community biomass peak lasts from March to June with a secondary maximum between October and January.
