| environmental dna reveals that rivers are conveyer belts of biodiversity information. | dna sampled from the environment (edna) is a useful way to uncover biodiversity patterns. by combining a conceptual model and empirical data, we test whether edna transported in river networks can be used as an integrative way to assess eukaryotic biodiversity for broad spatial scales and across the land-water interface. using an edna metabarcode approach, we detect 296 families of eukaryotes, spanning 19 phyla across the catchment of a river. we show for a subset of these families that edna sam ... | 2016 | 27572523 |
