Primary production rates and total phosphorus concentrations indicated that Lake Geneva (Switzerland) was meso-eutrophic from 1970 to 1983. Worm communities of the profundal (50–309 m deep) were very similar in 1978 and 1983. Species numerically dominant in eutrophic lakes — such as Potamothrix hammoniensis, P. heuscheri and Tubifex tubifex — constituted the bulk (75%) of the communities. Species numerically dominant in mesotrophic lakes (mostly Potamothrix vejdovskyi) or in oligotrophic lakes… CONTINUE READING
