QUANTIFYING THE STRUCTURAL AND FUNCTIONAL RESPONSES OF MACROINVERTEBRATE COMMUNITIES TO ANTHROPOGENICALLY ALTERED FLOWS OVER A >20 YEAR PERIOD
The flow regime of lotic environments is widely regarded as a primary control shaping the structure and function of river ecosystems. Hydrological alterations within such environments have been proven to degrade the health of river environments globally. However, the ecological implications of groundwater abstraction practices have been historically understudied. In this study, we utilize a regional groundwater model to examine long-term (1995-2016) macroinvertebrate community responses to antecedent observed hydrological variability and the percentage of daily flows modified by anthropogenic activities (including groundwater abstraction practices). Both the structure and function of macroinvertebrate communities responded to observed hydrological variability (including flood and drought and events) and anthropogenic flow alterations. Results from this study could be used to guide environment regulators and regional water companies on how specific hydrological events and modified flow regimes are shaping lotic ecosystems over long-term periods.
