METABARCODING AND BIODIVERSITY IN STREAMS: USING MULTIPLE TOOLS TO ASSESS AQUATIC ECOSYSTEMS
Stream ecosystems are a complex assemblage of macro and microorganisms which respond to external stressors, including temperature, land use, nutrients, and contaminants. The composition, diversity and function of these organisms may be an important indicator of stream health and function, and species assemblages, such as invertebrates, periphyton and fish are used to evaluate stream ecosystem health and biodiversity. eDNA metabarcoding potentially allows resource managers to identify a wider range of species at substantially lower cost. We used standard barcodes (16S, 18S and CO1) to identify bacteria, algae, and vertebrate species in water samples collected from 40 NH streams. Data on water chemistry, land use and invertebrates is also available at each site. We are applying multivariate and phylogenic network analyses to identify correlations between biodiversity metrics within and across taxonomic groups and water quality stressors. Initial analysis shows decreasing biodiversity associated with temperature and nutrients, and we will discuss these results, along with some of the challenges we have encountered.
