The North Atlantic Oscillation and plankton dynamics in two European lakes –‐ two variations on a general theme
Summary Long‐term data on water temperature, phytoplankton biovolume, Bosmina and Daphnia abundance and the timing of the clear‐water phase were compared and analysed with respect to the influence of the North Atlantic Oscillation (NAO) in two strongly contrasting lakes in central Europe. In small,...
