Life cycle and spatial distribution of the amphipod Pallasea quadrispinosa in a lake in northern Sweden

The population structure and spatial distribution of the “glacial relict” Pallasea quadrispinosa were studied in Lake Stora “Ofsjön”. Samples were taken at three depths throughout an eleven month period. The amphipods had an annual‐biennial life cycle. The reproductive period started in October, and...
