Pesticide pollution in small streams and invertebrate community responses – an overview of the current state
Freshwater ecosystems are subject to a multitude of stressors. In agricultural areas, pesticides play a major role. They can enter water bodies via spraydrift, subsurface drainage and runoff. We present the results from a review of field studies on the effects of pesticides on invertebrate communities in freshwater ecosystems. Despite complex pesticide regulation, effects of agricultural pesticide use (mainly insecticides and fungicides) on invertebrate communities have been reported in different regions of the world in the literature. However, most of these studies were conducted in regions of high intensity agriculture such as in Western Europe or North America. Furthermore, most studies were limited to the local or regional scale. Hence, we also present recent results from studies on pesticide pollution and the response of invertebrate communities and adjacent riparian ecosystems from a region with low intensity agriculture in Central Europe. In addition, we report results from a comprehensive large scale monitoring study in Germany. We discuss the problem of establishing causality based on field studies in a community ecological context and outline promising future research directions.
