A systematic review evaluating the performance of eDNA methods relative to conventional methods for biodiversity monitoring
The rapid adoption of environmental DNA (eDNA) methods has drastically changed biodiversity monitoring efforts. It is often claimed that eDNA methods are more sensitive and efficient than conventiona...

This difference meant there was an increase in the proportion of the eDNA sample made up of small particles as we moved "downstream". More evidence that eDNA removal in streams is an interplay of physical and biotic factors. And this can be influenced by temp!

So what did we find?

At higher temps, small eDNA particles (0.2–1.0 μm), were removed faster than at lower temps, while removal rates were consistent across temps for larger eDNA particles (>1.0 μm).

We conditioned these handy recirculating mesocosms (at #NotreDame) under a range of temperatures. Then we added #eDNA from from two fish species and and took H2O samples over time to measure removal rates for different eDNA sizes. SO to @abagaelpruitt.bsky.social letting me use her experiment setup!

New paper out today!!

We know warming speeds up eDNA removal in lakes and ponds, but what about streams and rivers where physical removal may obscure the impact of decay?

Warming Increases Environmental DNA (eDNA) Removal Rates in Flowing Waters
This study experimentally investigated how warmer water temperatures impact eDNA removal rates in flowing waters. Using recirculating mesocosms with varying water temperatures (20°C, 23°C, and 26°C) ...

New paper alert! 🚨- My final PhD chapter is finally out!

What happens to different eDNA components in water? 🌊💧

We tested particle size (small vs. large) and DNA molecule length (86 vs. 387 bp) in recirculating streams—and what we found might surprise you! 🧵👇
