Volatile Organic Compound (VOC) Exchange in Tropical Leaf Litter in Response to Wetting: An Automated Scheme to Classify Flux Pulse Dynamics

Wetting of decomposing leaf litter triggered the emission and uptake of 121 potential VOCs including methanol, acetaldehyde, and acetone Most VOCs appear to originate from plant processes, althou...

Postdoc position at UA! Join a new NSF project to improve understanding of the atmospheric H2 soil sink and its response to H2 emissions with new flux measurements. Excellent exposure to different disciplines and career paths. Please share and apply by Sept 30 arizona.csod.com/ux/ats/caree...

New NSF award: the future of the atmospheric hydrogen (H2) sink-is adaptation enough? 📣 Postdoc and PhD positions to be advertised soon 👀 Extreme gratitude for the Atmospheric Chemistry and Ecosystem Science Programs for their support. @aerodyne.com

We are hosting a PhD course on volatiles in ecosystems for 30 international PhD students. Today we heard flash talks by all participants, got an introduction to isotopes, a lab tour and a tour in the Botanical Garden of #SNM. We are thankful for Faculty of Science @ucph.bsky.social for funding.

Has anyone else used Qiagen's PowerProtect solution (now that LifeGuard is unavailable) but with success extracting DNA/RNA from soil samples?

I’m happy to share our recent review published in The ISME Journal! Here, we explore the role of CO and H₂ oxidisers in oligotrophic environments. This work was a collaboration with Philippe Constant, Gary King, and @hendrikschaefer.bsky.social. Hope you enjoy it! academic.oup.com/ismej/articl...

Metabolism of CO and H2 by pioneer bacteria in volcanic soils and the phyllosphere

Abstract. Trace gas degradation is a widespread metabolic adaptation in microbial communities, driving chemosynthesis and providing auxiliary energy that e

Genomic and metagenomic survey of microbial carbonic anhydrase genes reveals novel clades, high diversity, and biome-specificity

Carbonic anhydrase (CA) enzymes catalyze the interconversion of carbon dioxide and bicarbonate with an efficiency exceeded only by superoxide dismutase. CA enzymes have convergently evolved multiple t...
