Come work with us! #PhD position on #ecosystem and #biodiversity effects of large #herbivores on the Eurasian steppes now announced: www.euraxess.de/jobs/395512

Nice combination of fieldwork and meta-analysis, co-supervised by @jonastrepel.bsky.social and ejlundgren.github.io

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.

#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.

Next generation Arctic vegetation maps: Aboveground plant biomass and woody dominance mapped at 30 m resolution across the tundra biome The Arctic is warming faster than anywhere else on Earth, placing tundra ecosystems at the forefront of global climate change. Plant biomass is a fund…

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.

Our study ‘The global human impact on biodiversity’ is out in Nature!

Through an unprecedented synthesis (2133 studies!) we show that humans are not only shrinking species numbers—but reshaping entire communities across the planet. 🌍🌐🐟🌿🪲

Great fieldwork in Siberia during pre-war times

🌳 These heterogeneous burn areas contain small unburned patches that may be crucial for post-fire vegetation recovery.
🏞️ Pre-fire topography and vegetation conditions were key predictors for burn patterns, offering potential improvements for future fire spread models.

🛰️ We used high-resolution (3 m) satellite imagery to map patchy tundra fire scars from the extreme 2020 Siberian fire season.
🔍 Our fine-scale analysis revealed mixed burned/unburned areas missed by previous studies, potentially underestimating fire effects like carbon emissions.

Pre‐Fire Vegetation Conditions and Topography Shape Burn Mosaics of Siberian Tundra Fire Scars Fine-scale burn patterns of Siberian tundra fires led to an underestimation of burned area in medium-resolution satellite products Small unburned patches (<30 m)–which are crucial for post-fire e...

Thank you, Robert!

Thanks a lot for this Pack! Could you add me as well, please?

Coloured dots on a circumpolar Arctic map show data from the 15 datasets included.

We call for future studies to address possible tundra ecosystem shifts linked to fires, using methods that cover greater temporal and spatial scales.

We hypothesise that post-fire tundra recovery, coupled with climate change, may not return to pre-fire conditions.
We propose two climate-fire driven trajectories:
1) Low fire frequency 🔥: Increased woody vegetation 🌳
2) High fire frequency 🔥🔥🔥: Grass dominance 🌾

Trends in the long-term development of vegetation cover of five plant functional types after tundra fires

Our review synthesises current knowledge on post-fire vegetation cover trajectories in Arctic tundra ecosystems:

Oil and gas extraction regions are the hotspots of light-emitting human activity in the Arctic

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.
