Description
- One of the greatest threats to lotic ecosystems is flow regulation. The impacts of flow regulation on native fish are often mitigated using periodic water allocations, termed environmental flows. The effectiveness of environmental flows has been studied in some systems, but the role of flow conditions prior to water allocation (i.e. antecedent conditions) has rarely been quantified.
- We evaluated the effects of floodplain inundation due to variable river flows on fish abundance in wetlands of the mid‐Murray River, Australia, using a hierarchical multi‐species model parameterized to estimate fish abundance while accounting for variable detection. We evaluated the effects of antecedent conditions on three time‐scales, including patterns in long‐term (5 years prior), medium‐term (1 year prior) and short‐term (3 months prior) wetland inundations.
- While species‐specific responses to antecedent conditions varied, we found …
