Wartime and Postwar Historiography, 1940–53kkojärvi. Strong thermal and chemical stratification developed in the water column early in spring and led rapidly to anoxia in the hypolimnion, which extended to less than 1.0 m from the surface. In the epilimnion only small bacteria were abundant. In the anoxie zone both the abundance and the mean

Reinventing the State of Nature are released, processed, transported to, and then further processed within the recipient waters. Operational couplings and integrations in freshwater ecosystems occur along physical and metabolic gradients of a number of scales from micrometer to kilometer dimensions. The operation and turnover of

Impacts of moss on the metabolism of bacterioplankton, phytoplankton and Zooplankton in polyhumic water were investigated in laboratory throughflow systems. Growing .
