Mismatch in reindeer resilience to past and future warming signals ongoing declines

Rangifer population dynamics over 21,000 years reveal that future climatic warming will cause losses that surpass safe boundaries.

🌸Plant diversity dynamics over space and time in a warming Arctic 🌸

Our new study @nature.com analysed plant diversity change in >2000 tundra plots over 4 decades. We found that plants changed unevenly, mostly driven by warming and biotic interactions.

We find that associations between species are very plastic and that bonds between partners vary with environmental conditions. In a rapidly changing Arctic, the current structure of plant-root associations may be severely altered - yet, the plasticity may provide some resilience of the system.
