A four panel figure showing (a) a biologist wading in a turbid river with a water sample, (b) a real-time or quantitative PCR amplification plot with a positive environmental DNA detection, (c) a biologist searching concrete riprap on a river bank, and (d) two freshwater mussels that have been marked for future monitoring and recapture.

Another example of the power of environmental DNA (eDNA): a positive eDNA detection led to the rediscovery of a freshwater mussel not found live in Illinois for over a century. New student-led, open access paper in Ecology with @markdavis79.bsky.social at doi.org/10.1002/ecy....

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...

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 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?

Global decoupling of functional and phylogenetic diversity in plant communities - Nature Ecology & Evolution Functional diversity and phylogenetic diversity are expected to be positively correlated. Here the authors show that the covariation between these metrics in vascular plant communities around the worl...

🌳 New findings 🌳

Phylogenetic diversity cannot be used as a proxy for functional diversity in vascular plant communities 🌲🌳🌴🌵🌱🍀🌾🌼 We used the #sPlot database & found a pronounced decoupling between phylogenetic & functional diversity ⬇️

‘The Mountain Wagtail’: How Pollution and Mining Are Destroying Kyrgyzstan • The Revelator As mining operations destroy millennia-old glaciers, director Begaly Nargozu’s film reflects a disappearing landscape and culture.

All the Plants We Cannot See • The Revelator Our culture has moved away from a fascination with the greenery around us. Experts warn that “plant blindness” could come with a cost.

One of the most terrifying things I ever encountered doing field work was pulling a seine and finding one of those systematically dismantling and consuming a northern leopard frog. It haunts my dreams to this day.

Meet the world's largest, deadliest bug that can suck the life out of fish many times its size - effectively turning its prey into one giant protein smoothie All you need to know about the deadly giant water bug that attacks anything that moves - even humans, hence its nickname 'toe-biter'.

Every summer I get questions about giant water bugs – a different species than this in my neck of the woods.

They’re such big, dramatic creatures!

“…L. maximus grows to nearly 12 cm long and can take down a vertebrate many times its size.”
