| description |
This paper presents data on the distribution of G. lacustris in Lom municipality, Oppland County, southern Norway. The species has been recorded at 20 different localities. The occurrence of G. lacustris in the studied area seems mainly to be affected by the hydrogen ion concentration and total hardness of the water. Fish predation pressure may also influence the occurrence and abundance of this crustacean. G. lacustris survived a water level fluctuation of 7.3 m (range 3.7 m - 11.8 m) in the Tesse hydro-electric reservoir, during a period of 20 years, but not the more recent annual changes in water level of 12.2 m.
