Effects of the agricultural sector on the physico-chemistry and the ecosystem quality of inland waters
… links between the agricultural sector and the physicochemical condition and ecosystem health of inland waters. In order to create a comprehensive model, two analytical tools have been used, on the one hand the "Driving forces – Pressure - State – Impact - Response" (DPSIR) modeling framework …

Structure and function of zooplankton colonization in twelve new experimental ponds
… the Random Placement Hypothesis (Coleman 1981). Physico-chemistry, zooplankton colonization dynamics, zooplankton community structure and function were analyzed every two weeks from 5 February 1988 to 10 February 1989. Ponds varied in physico-chemistry at points in time but followed similar …
