Most animals have their own version of tree rings – here’s how we biologists use them to help species thrive
From whale earwax to bird feathers, almost all organisms keep a record of their existence.

New paper out 🐟📏📉📈!
We explored 50 years of data from 14 Atlantic salmon populations across Eastern Canada to see how body size, age, and life-history diversity have been changing.

If you want to learn how to use stable isotope analysis for ecological research, my colleague has launched two online courses about this method. One is basic principles and one is R analysis of data.

What a great #FLFDevNet training course! Lots of new concepts & tips to help us be a better version of ourselves. A few I'm trying straight away...
1. ID 3 daily wins (gratitude)
2. Listen harder (let in the silence!)
3. ID key values
4. When questioning someone avoid "why"
5. Situational leadership

What do you think has been on Earth longer - sharks or trees?
You might think trees have been around for a long time, but sharks have been here even longer!
See how sharks have survived and thrived through all five of Earth’s mass extinction events in this week’s Surprising Science.

Rivers are heating up faster than the air − that’s a problem for aquatic life and people
River heat waves are rising faster than the pace of air heat waves. That’s a problem for fish, drinking water quality, and food and energy production.

Amazing effort!!!
Quite a day out: 43 miles running up the Exe to celebrate and connect with the story of Atlantic Salmon in this year's Salmon Run. A big thanks to all involved in organising and supporting the event and to everyone who donated towards WRT's work to support salmon restoration in the Exe.

Atlantic salmon leaping up the Falls of Feugh. Exhausting even just watching them do it! We didn't see any make it to the top. Wonder if this dry summer has made it harder..... 😪
