Abstract
An analysis of the remains of Bosmina (Eubosmina) in a sediment core from the pre-alpine, mesotrophic Starnberger See showed that the lake was inhabited by B. longispina since the Oldest Dryas. In the Subatlantic- -1900 years ago — the kessleri morph of B. coregoni invaded the lake and both taxa have since co-existed. Although there was considerable morphological variation, B. longispina clearly differed from Circumbaltic populations through most of the late Pleistocene and Holocene periods. In the recent Bosmina fauna of the lake two morphologically well separated taxa (B. longispina ruehei and a morph of B. coregoni) occur which differ clearly from the Bosmina remains found in the core up to the uppermost sample from 7 cm sediment depth. B. coregonif. kessleri appeared in the lake in a period when it was supposedly still oligotrophic. The Bosmina succession observed in the Starnberger See resembles the pattern found in deep north German lakes.
