MACROINVERTEBRATE RESPONSE TO LOSS OF CURRENT DURING LOW FLOW EVENTS IN LOWLAND STREAMS
Environmental change leads to an increase in periods of low flow in northwestern European lowland streams. One of the most common effects observed in the temperate zone is the temporal loss of current, transforming streams into stagnant water bodies. During these stagnation events the environmental conditions in the stream change drastically. To understand the effects of stagnation on the macroinvertebrate community inhabiting these systems, a 10-week field experiment (BACI) was carried out in which flow was manipulated to allow comparison between a stagnant and a flowing reach. We investigated the effects of stagnation on the macroinvertebrate community composition and characterized the changes in environmental conditions (DO, nutrients) and habitat structure (substrates, vegetation). Habitat preferences of the species collected (amongst others rheophily, saproby, sensitivity for low flows) were used to derive indicators for the different phases of degradation during stagnation.
