Multiple stressors and stream macroinvertebrate community dynamics: Interactions between fine sediment grain size and flow velocity
Original language description
Agricultural development has resulted in the degradation of freshwater ecosystems worldwide. Two key stressors impacting streams and rivers draining agricultural catchments are deposited fine sediment (e.g. due to erosion) and reduced flows (e.g. due to water abstraction, dams, or climate change). Past studies have identified fine sediment as a master stressor in streams, but the effects of different sediment grain sizes in combination with reduced flow velocity are poorly understood. We manipulated deposited fine sediment (no added sediment silt: 0 to 0,125 mm fine sand: 0,125 to 0,250 mm coarse sand: 1 to 2 mm) and flow velocity (fast: 26,5 cm/s medium: 13,9 cm/s slow: 0,0 cm/s) simultaneously in 60 outdoor stream mesocosms. We determined the individual and combined effects of these stressors on the benthic, drifting, and emerging stream macroinvertebrate communities. Both fine sediment and reduced flow velocity had pervasive detrimental impacts on stream invertebrate communities. Negative
