New paper from DEEP researchers at @stockholm-uni.bsky.social 🌿🐌

The study shows indirect microclimate effects on lichen performance: warmer, more humid conditions boost mollusc grazing, which reduces lichen growth near its warm‑range margin. Access the paper below!

You can still join us on Wednesday for our annual Bert Bolin Climate Lecture!

It's our pleasure to have Dr. Valérie Masson-Delmotte (@valmasdel.bsky.social) as our lecturer this year — sharing her experience as a paleoclimatologist.

Contrasting thermophilization among forests, grasslands and alpine summits - Nature Analyses of large-scale, multitaxa and long-term thermophilization patterns in forests, grasslands and alpine summits across Europe provide insight into shifts in community composition among different...

New paper in @nature.com!

European plant communities are shifting with warming, but not equally across ecosystems. Alpine vegetation shows the strongest change, while forests and grasslands lag behind.

Co-authored by Ove Eriksson (DEEP).

Registration is now open for the Bert Bolin Climate Lecture 2026! 🌍

This year’s speaker, Dr. Valérie Masson-Delmotte, will discuss how natural climate archives like ice cores and tree rings help us understand future climate change.

Hur långt kan blomsterlupinen sprida sig i Sverige – och vad styr var den finns? 🌿

En ny studie från DEEPs Olle Lindestad, publicerad i Ecosphere, visar att klimatet sätter ramarna – men att människor styr spridningen lokalt.

Potassium silicate improves cellular sodium homeostasis in wheat (Triticum aestivum L.) cultivars differing in salt resistance Potassium silicate can decrease the uptake of sodium (Na+) into wheat cells by affecting the Na+ uptake channels and increasing ion homeostasis.

New publication from DEEP! 🌾

The study shows that potassium silicate reduces cytosolic Na⁺ in wheat mesophyll cells, shedding light on mechanisms behind salt tolerance in different cultivars.
