Transgenic crops release Cry proteins into streams. But what does that mean for aquatic insects?🌱💧🐛 We measured and barcoded 1,800+ caddisflies across 25 streams. Environmental factors like temperature, land use explained most patterns. Cry1Ab had limited impact. academic.oup.com/ee/article/5...

I'm looking for postdoc positions in freshwater biogeochemistry! Interested in any projects investigating nutrient and carbon cycling, phytoplankton coupling with dissolved organic matter cycling in human-altered landscapes, or hydrology and spatial modeling!

Wouldn’t it be kind of wild if someone actually pulled everything we know about what happens to eDNA between shedding and detection? Decay, transport, microbes, temperature, rivers, oceans, all of it?! We did that. 📄 Preprint link: www.researchsquare.com/article/rs-8... 🧬🔍🌊 #eDNA #MolecularEcology

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? onlinelibrary.wiley.com/doi/10.1002/...

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! 🧵👇 #eDNA #MolecularEcology 🔗 Read more:
