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...

Assessing morphological, developmental, and genetic responses of Hydropsychid caddisflies to Cry1Ab exposure

Abstract. Transgenic crops expressing Cry proteins are widely cultivated to reduce crop damage from insect pests. However, Cry proteins can leach from tran

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

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...

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:

Comparing the Fate of eDNA by Particle Sizes and Molecule Lengths in Recirculating Streams

The detection of environmental DNA (eDNA) has revolutionized aquatic species monitoring, yet interpreting eDNA data remains challenging due to gaps in our understanding of eDNA ecology (i.e., origin,...
