EXPLORING THE RELATIONSHIP BETWEEN FLOW AND METACOMMUNITIES IN CATCHMENTS
The effects of flow disturbance on freshwater benthic invertebrates have been studied in the context of floods, droughts and variability. More recently, we have taken advantage of large deployments of flow gauges and flow modeling to mechanistically understand how hydrographs are interacting with species sorting and movement in catchments. By utilizing readily available flow gauge data within the Sierra Nevada Mountains in California, we sought to relate ecologically important parts of the hydrograph to large spatial patterns in the benthic invertebrate community. We did this by calculating various flow metrics, and observing which ones described most variation in the benthic community. Then, we analyzed the extent to which various metrics and space were structuring the benthic community along a catchment. The benthic community was structured according to flow at sites with a lesser prevalence of dams, while there was more spatial structuring evident in catchments with a strong presence of flow regulation. Ongoing methods comparisons will help further our understanding of the relationship between flow and metacommunity dynamics.
