New paper out in Molecular Ecology 🐟🧬 Led by Julien Beaulieu, we show environmental RNA (eRNA) can estimate freshwater fish biomass & abundance in the wild — outperforming eDNA. Mitochondrial eRNA tracked Brook Trout numbers best. First demonstration in natural lakes 👇 doi.org/10.1111/mec....

Title graphic over a reflective Rocky Mountain lake reading "Reading the water, in real time," with a subtitle on environmental RNA outperforming environmental DNA. A bar chart ranks four markers by how well they tracked fish biomass: eRNA cyt b scores highest at 0.59 (marked "best"), followed by eRNA 18S (0.32), eDNA cyt b (0.22), and eDNA 18S (0.10).

It's not all about DNA. RNA could transform real-time environmental surveillance. By vanishing quickly, RNA avoids DNA’s problem of lingering too long, giving ecologists a sharper, more immediate picture of life in lakes, rivers, and beyond. www.anthropocenemagazine.org/?p=238665
