I am currently working on a project looking at remnants of prey eDNA in a species of seabird across several populations. Birds, and other flying animals, are pretty good organisms for studying diet by eDNA because they conveniently defecate far from where they feed. This is not only good etiquette, but it makes interpretation of results much easier as it reduces potential confounding results from exogenous DNA. This makes seabirds good “biosamplers” to understand plankton community succession dynamics.
I will write more as I get further with this project . . .
