Mark and Jesse’s year-long study of East River eDNA “Biomonitoring in the Anthropocene: Urban estuary environmental DNA tracks marine fish, terrestrial wildlife, and human diet” is published today in PloS ONE. The findings suggest that urban waterways anywhere could become continuous biosensors, tracking biodiversity, habitat restoration outcomes, and human impacts in real time. Among the most novel results of the weekly East River sampling were genetic indicators of human food consumption, of rat and other terrestrial wildlife populations, and the discovery of newly abundant fish species, thought to reflect the success of habitat restoration efforts. Our lively press release is posted here and graphic highlights here.
