Big congratulations to our deputy director Gustaf Hugelius, who was just awarded a ERC Syngergy Grant for the project “Northern Peatlands in the face of climate warming and abrupt changes (CLIMPEAT).” 👏

This is why we are relaunching the scientific journal #Tellus — to strengthen open, researcher-led publishing. “We want to promote learning and careful scientific communication” says director Ilona Riipinen. Read the article below.👇

Klimatmötet COP30 i Brasilien blir en påminnelse om ett grundläggande problem: Politikerna behöver aktuella vetenskapliga underlag, men får dem för sällan och vid fel tillfällen. Klimatforskarna Örjan Gustafsson och Svante Bodin föreslår tre reformer för att lösa problemet. vist.ly/4cxw7

New in Basic & Applied Ecology! Researchers at DEEP have looked at how soil moisture and surrounding forest cover influence Armillaria root rot incidence—highlighting how local habitat conditions shape forest health👇 @stockholm-uni.bsky.social @bolincentre.bsky.social

How do biodiversity and productivity interact in agroforests? A new paper in Basic and Applied Ecology by researchers at DEEP reveals how bird and bat diversity affects herbivory and yield trade-offs in Arabica coffee’s native range.🦇☕ @stockholm-uni.bsky.social @bolincentre.bsky.social

Winter has come to Tarfala meteorologically www.svt.se/nyheter/sapm.... This often means irregular transmission from our #TimeLapseCamera at #LakeTarfala. Ice-on happened between 7 and 22 october, the "normal range" bolin.su.se/data/tarfala... @bolincentre.bsky.social @stockholm-uni.bsky.social

Pulitzer-winning writer @elizkolbert.bsky.social visited the Bolin Centre & @stockholm-uni.bsky.social to explore how Svante Arrhenius’s 19th-century ideas still shape our understanding of global warming and climate change. Read about her visit and upcoming project on our website. 👇

Lignin diversity helps plants thrive on land – without them, they become small, sterile plants that produce far less biomass. 🪴 This is revealed in a new study in @newphyt.bsky.social by @stockholm-uni.bsky.social @bolincentre.bsky.social @uspoficial.bsky.social & #TUAT 👇

Varmare och torrare somrar gör skogarna mer sårbara för granbarkborrar. En ny studie av bl a Caroline Greiser, Stockholms univ, visar att angreppen höjer temperaturen i drabbade områden. Men lövträd pekas ut som lösningen på uppvärmningseffekten. @bolincentre.bsky.social www.svt.se/nyheter/loka...

Dandelions that clone themselves still make pollen, but why? The #NoSexPoorPollen project led by @yannickwoudstra.bsky.social studies how pollen degrades when it’s no longer needed for sex, and what that means for evolution 🌼 Learn more about the project below!

New study out in @science.orgs Science Advances! 📣 The uplift of East Africa during the Miocene epoch dramatically transformed the region’s climate and ecosystems, promoting the expansion of grassland and reshaping habitats for mammals and early hominoids. 👇 @stockholm-uni.bsky.social @ethz.ch

New collaborative paper out, with results on lake-terminating Kaskasapakte Glacier in the surroundings of #TarfalaResearchStation @bolincentre.bsky.social @stockholm-uni.bsky.social, looking at its retreat dynamics through the lense of increasing lake temperatures. tc.copernicus.org/articles/19/...

Correction: the record minus year was 2024, not 2022. Should also be corrected now at SverigesRadio's site. And Time Lapse Camera imagery from 30 minutes ago shows snow in the Tarfala Valley :) @stockholm-uni.bsky.social @bolincentre.bsky.social

Det är viktigare än någonsin att följa glaciärerna i detalj, menar glaciologen Nina Kirchner. F&F besökte henne på Tarfala forskningsstation och fick följa med till världens mest undersökta glaciär. vist.ly/47uws

New in @oikosjournal.bsky.social! 📃 The study, led by Peter Hambäck at DEEP, explores how interactions between hosts and enemies shape biodiversity. Results show that bottom–up and top–down diversification don’t work the same way, and that parasitoids often adapt faster than their hosts.👇

And here comes the snow ❄️ Summer is indeed short: Left: today. Middle: 14 june. But there WAS summer in between (Right) 😀Last post from the station tomorrow @stockholm-uni.bsky.social @bolincentre.bsky.social

First nightfrost, followed by a beautiful sunny morning, captured by our Time Lapse Camera at #LakeTarfala. These are the last days before closing the station @stockholm-uni.bsky.social @bolincentre.bsky.social after more than 3 months of 24/7 operation👍 #glacier #massbalance results to come soon!

For the first time since Stockholm Univ. was awarded UN observer status, a researcher (Prado Domercq) attended negotiations on a global treaty to end plastic pollution as part of the Scientists' Coalition for an Effective Plastics Treaty. @marleneagerstrand.bsky.social www.su.se/department-o...

End of season is approaching at Tarfala Research Station @stockholm-uni.bsky.social @bolincentre.bsky.social. Autumn colours at the station, #glacier #massbalance measurements in full swing @matthias-huss.bsky.social @vaw-glaciology.bsky.social @swisspolar.bsky.social, now also with a #SmartStake 👍

See Prof. Nina Kirchner, director of @tarfalaresstation.bsky.social, in @svtnyheter.bsky.social earlier today on how the southern peak of #Kebenekaise continues to melt. 1,5 meters since last year... 🌡️⛰️🥵 (In Swedish)

This year's measurement of Kebnekaise's southern peak by @tarfalaresstation.bsky.social shows that the peak has decreased by 1.5 metres compared to last year. This is the seventh year in a row that Kebnekaise´s southern peak is lower than the northern peak. #Climate #Arctic www.su.se/english/news...

Tarfala forskningsstation @stockholm-uni.bsky.social @bolincentre.bsky.social bidrar med en föreläsning om glaciärer och glaciäråret 2024/2025 som avslutas snart innan den första snön kommer (ja, ett glaciärår är inte samma som ett kalenderår 😀). Välkommen! forskarfredag.se/program/glac...

Great read in Swedish by @fof.se with member @linegreis.bsky.social! 👇 The European spruce bark beetle is affecting the forest microclimate, making it up to 2°C warmer.🪲🌡️ Discover how below.

📣Join us at DEEP! We have several open positions at the moment: - Postdoc Fellow in Evolutionary Genomics - PhD student in Fungal Evolutionary Biology - PhD student in Fungal Biology - Research engineer in Fungal Biology Help us spread the word! 🗣️ @stockholm-uni.bsky.social

The @ipcc.bsky.social has selected 3 Bolin Centre researchers as authors for the upcoming Seventh Assessment Report (AR7) – congratulations to deputy director Gustaf Hugelius, Ninis Rosqvist and Erik Kjellström! 👏 @stockholm-uni.bsky.social

New study in @heredityjournal.bsky.social shows how leaf beetles evolve defence genes to fight off a shared parasitoid wasp. 🪲🦟 Co-authored by researchers at DEEP, this study reveals lineage-specific targets of positive selection, offering fresh insights into host–parasite coevolution. 👇

A study co-authored by Prof. Hambäck at DEEP shows that wild bee diversity drives apple seed set much more than managed honeybees. Functional diversity makes the biggest difference. The takeaway: healthy, diverse wild pollinator communities are key for productive orchards. 🐝🍎 Access it here:

Tarfala Research Station's 80 yrs Anniversary conference concluded with an excursion to #Storglaciären and lots of discussions with international guests from US, Spain, Switzerland #WGMS as well as from #SwedishPolarResearch. Thank you all and @stockholm-uni.bsky.social @bolincentre.bsky.social

"Like many dysfunctional relationships, the UNFCCC and the IPCC need to talk more" Read comment in @climatechangenews.com by Örjan Gustafsson and Svante Bodin at @bolincentre.bsky.social #Climate #ClimatChange #UN #IPCC #UNFCCC

The structural divide between the IPCC and UNFCCC is hindering timely and effective climate action, says members Svante Bodin and Örjan Gustafsson. The misalignment in timing, relevance, and communication between the two bodies limits the global response to the climate crisis. ‼️
