Das Bankensystem in Deutschland,s been little appreciation to date of the interactions between top-down (grazing) control and bottom-up (nutrient supply) control on the structure and nutrient cycling processes within these webs. The quality of nutrient supply, both in terms of the relative proportion of inorganic: organic nitrogen

An outline is here given of how the elementary size-related physical laws of diffusion and sinking, combined with the assumption of predators being size selective in their choice of prey, give a theoretical foundation for this type of structure. It is shown how such a

Grundlagen des elektrischen Antriebs, nutrient loadings and fish communities in southwest Finland. Lake Pyhäjärvi was weakly mesotrophic in 1980–1996, Lake Köyliönjärvi was highly eutrophic in 1991–1996, and Lake Littoistenjärvi was mesotrophic in 1993–1996 and eutrophic in 1992. In Lake Pyhäjärvi, natural year-class fluctuations of ve

Nearly all measured variables (e.g. POC, chlorophyll .) appear to be conservatively mixed along the salinity gradient between 2 and 8 PSU which is

Besides experimentations, nutrient limitation of plankton has been extensively studied by direct chemical analyses. We used the latter approach in this work. Nutrient limitation was studied by calculating different nutrient r
