How environmental RNA can give us a real-time picture of freshwater biodiversity As climate change and human activity threaten freshwater ecosystems like lakes and rivers, it's more important than ever to know how the species who inhabit them are being impacted. But traditional methods of monitoring species, such as catching animals, are challenging to implement and can miss rapid changes.

🌊 Whispers from our lakes & rivers… How are hidden species faring as the world changes? New ways to listen are vital! 🔎 #FreshwaterLife ✨

They might not be native to the UK, but they are a good looking amphibian - Alpine Newt
Easy to identify males when torch surveying a pond as they almost glow blue under torchlight
