USING DNA-METABARCODING TO LINK BIODIVERSITY AND ECOSYSTEM FUNCTION ACROSS A LARGE-RIVER FLOODPLAIN DISTURBANCE GRADIENT
Floodplains are among the most productive ecosystems in the world, yet they are threatened worldwide by increased urbanization and water management. These disturbances are threatening the connectivity of floodplains that transfer essential sediment and nutrients to wetlands, which themselves are important habitats for diverse benthic communities and provide essential ecosystem services. With up to 90% of floodplains in North America and Europe altered to the point of functional extinction, it is vital to conserve those that remain intact, such as the Lower Saint John River and its associated floodplain, including the Grand Lake Meadows (GLM). At 9000 ha, the GLM is Atlantic Canada’s largest freshwater wetland complex, which contains a mosaic of patches experiencing different combinations of stressors, thus providing a unique opportunity to assess how disturbance and management affect ecosystem health. Using high-throughput genomics sequencing methods that reliably characterize community composition in unprecedented detail, thus study links benthic macroinvertebrate biodiversity to measures of ecosystem function, such as decomposition and primary production. Specifically, we ask (1) How does disturbances influence benthic macroinvertebrate communities? (2) What species are driving community responses? (3) How is invertebrate community structure associated with ecosystem function?
