Multi-stress interaction effects on BVOC emission fingerprints from Oak and Beech: A cross-investigation using Machine Learning and Positive Matrix Factorization Abstract. Forest ecosystems are increasingly stressed through heatwaves, drought periods, and other factors such as ozone pollution or insect infestations. These stressors have a profound impact on th...

We at @voltcenter.bsky.social just held a very engaging mini symposium on polar biogeochemical cycles today.

As per usual, VOLT-all meetings are fuelled by cake and good science. Here are a couple of pictures from a talk by @danilloalvarenga.bsky.social on #cyanobacterial #symbioses with #mosses and #lichens.

@voltcenter.bsky.social's centre-wide fortnightly meetings always have exciting talks. Sometimes by VOLT members, sometimes by guests. This time, we had a brilliant, surprising and insightful talk by @lonegram.bsky.social on the role of #antibiotic molecules in #microbial #ecosystems.

Today @jrieksta.bsky.social and her cat joined our #VOC lunch meeting to talk about her work on bark VOC emissions.

Kolby Jardine from Berkeley is visiting @voltcenter.bsky.social for a year, so we invited him to share his research plans for his time here. He gave a great overview on coupled assimilation of ammonia and C1 volatiles by leaves under elevated CO2 using laser spectroscopy measurements.

Kolby Jardine is an EESA area researcher who also works with #TeamBioSci. Kolby's unique path has left him inspired about science and the environment with every destination along the way.

#PlantScience

At @voltcenter.bsky.social we started the week with breakfast and discussions. Postdoc Wim Verbruggen introduced a cool paper on organizing principles in plant communities and how they can be used for ecosystem modeling: www.nature.com/articles/s41...

VOLT is celebrating the International Day of Women and Girls in Science! In the video below, we highlight some of the many dedicated women at the centre who advance research on VOCs and ecology from across all career stages in Science as they share their work and perspectives. youtu.be/E02l_bODeKQ

The resemblance is uncanny! 😂

Today at the breakfast journal club @mingyueyuan.bsky.social presented an exciting paper about linking species traits with ecosystem functioning

Today we started off the week with updates from our postdoc Cecilia Costas Selas on the impact of #phytoplankton #blooms on #VOCs. This is from the #seawater samples she and Eve Galen collected during a bloom last year.

Who said Mondays are tough? At VOLT we start our weeks with stimulating discussions over delicious breakfast. Today, postdoc Cecilia Costas presented and led a discussion on a paper about marine sulphur aerosols and their climate effects.

New year, new schedule for our @voltcenter.bsky.social- all meetings!
We kickoff with a great presentation by Sana James on the dataset she has been working on: high monoterpenoid emissions from Scots pine litter controlled by moisture.

The peatland columns collected from #StoreMosseNationalPark are now hibernating through the dark winter in climate chambers 🌱❄️ Waiting for a new “spring” for us to explore their #VOCs and carbon cycle processes.

Volatilomic complexity of three Northern Greenland bacterial isolates across a salt gradient Abstract. The High Arctic deserts of remote northern Greenland are expected to become warmer and wetter due to climate change. Precipitation changes will i

🎄Early Christmas news! Chapter IV of my PhD thesis has been accepted for publication in @femsmicro.org Microbiology Ecology 🤘

We show how three Greenlandic bacteria shift their VOC profiles along a salt gradient.

Stay tuned for another paper coming out soon! 🤞

Congratulations 👏
Looking forward to all the exciting results to come!

An exciting opportunity to showcase the story behind our research, from fieldwork in Greenland to labwork in Copenhagen! Springer Nature invited us to write a Behind the Paper post on our study of #VOCs in Greenland’s active layer soils.

The #pre-print for the Australian #fieldwork we did last February is now out! We show snow gum #dieback alters #volatile emissions, especially increasing #monoterpene #emissions from damaged trunks. You can read more here: doi.org/10.22541/ess...

The fieldwork sure was one to remember! 🌿🪲☁️🦘

We start the week with breakfast and scientific discussions. PhD student Mathilda Carlsson presented a paper on enantiomers of alpha-pinene as indicators of stress state in rain forests.

🎉 A big congrats to Luka Civa, @ucph.bsky.social, Marie Odgaard, @au.dk and Heide Wrobel Nørgaard, the winners of the DNRF Photo Competition 2025!
They will be celebrated today at our annual meeting in CPH. 📸✨
More about the winners👉https://dg.dk/en/the-winners-of-the-dnrf-photo-competition-2025/

This week's breakfast journal club was led by @kajsaroslund.bsky.social, where the relevant topic of fairness on peer review was discussed.

The lunch time meeting before the DNRF annual visit was busy, with an introduction from Jonathan Donhauser on his project on developing a #model for #microbial #VOC emissions, followed by practise talks by @nasmillelarkemejia.bsky.social and Ida Friis, which were a success on the day of the visit!
