Looking at the rise and fall of sockeye salmon using environmental DNA

Congratulations to SMEA alum’s Mike Tillotson and Jimmy Krajl, Professor Ryan Kelly, and co-authors on their recently published paper “Concentrations of environmental DNA (eDNA) reflect spawning salmon abundance at fine spatial and temporal scales.” The paper, published in Biological Conservation, was spearheaded by Tillotson and refers to water sampling data from a small stream in Alaska to look at the rise and fall of sockeye salmon DNA over a spawning run. Developing quick, cost-effective assessments of wild animal abundance is an important goal for many researchers, and eDNA holds much promise for this objective. The findings from this paper present an important step toward quantitative applications of eDNA in conservation and management.
