Feuer in der arktischen Tundra bedrohen Menschen und Biodiversität. Eine internationale Studie, an der Dr. Ramona Heim vom Institut für Landschaftsökologie beteiligt war, zeigt, dass diese Feuer nicht nur auf klimatische Faktoren zurückzuführen sind und belegt den Einfluss menschlicher Aktivitäten.

You can join my free online lecture on GitHub Copilot (Thu 18.12., 4-5 pm CET) I’ll show context-aware code completion, chatting with your scripts and projects & responsible use. I'll use R/Python + Positron; but works similarly in other languages/editors. 👉 Details & link: tinyurl.com/2xubc787

#Fieldwork update from our PyroDiv project (uni-goettingen.de/en/690609.html): A Kazakh-German field team is now collecting data on the Great Steppe to reveal the impact of fire legacies and grazing on biodiversity. Great collab between @acbk.bsky.social @consbiogoe.bsky.social and @uni-muenster.de.

🌸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. www.nature.com/articles/s41... 🧵 (1/7) 🌐🧪🌱🌍

First circumpolar maps of aboveground tundra biomass at 30 m resolution 💪 www.sciencedirect.com/science/arti... These new estimates show that in total tundra plants (above-and belowground) store around 8 Pg C while the upper 30 cm soils store ca 53 Pg C.

Industrial activity in the Arctic is rapidly increasing and now we can map hotspots of development at pan-Arctic scale. Our latest paper is out. www.pnas.org/doi/10.1073/...
