New @fwf-at.bsky.social CoE Microplanet study in @newphyt.bsky.social! Based on 70 years of data, CoE Key Researcher @christinakaiser.bsky.social and team @cemess.bsky.social @univie.ac.at show 50% loss in beneficial fungi due to high N-low K fertilizers. nph.onlinelibrary.wiley.com/doi/10.1111/...
New paper by @christinakaiser.bsky.social and #KianJenab from @ter-cemess.bsky.social at #CeMESS 🙌🌱🍄🟫
Uralte Symbiose zwischen Pflanzen und Pilzen: Christina Kaiser vom @cemess.bsky.social hat herausgefunden, dass diese Mykorrhizasymbiose sehr empfindlich auf Ungleichgewichte von bestimmten Nährstoffen im Boden reagiert. #univie
Was dies für eine nachhaltige Landwirtschaft bedeutet: ⤵️
A team led by ecologist @christinakaiser.bsky.social has discovered that mycorrhizal symbiosis is sensitive to imbalances of certain nutrients in the soil. The data come from an experiment that has been running for over 70 years.

1/3 〰️ CoE PhD students Thayer Taft from the lab of @christinakaiser.bsky.social and André Carvalho Araújo from the lab of @dagmarwoebken.bsky.social @cemess.bsky.social @univie.ac.at for their study on circadian clocks in the human gut, rhizosphere & desert biocrusts.
Use your chance to join the #TERRA team @unituebingen.bsky.social: 7-year position waiting for sbd. to advance #bioinformatic analysis in the context of bio-geo-diversity relations. Tübingen itself is a convincing reason, but our amazing #cluster team even more. We look forward to your application!
(2/2) While we rested our (speculative) conclusion on the observation of fermentation products after a pulse of simulated root exudation and estimated O2 depletion from CO2 emissions, this new paper now proved it using O2 sensors in combination with reverse Microdialysis. Really interesting read!
(1/2) Very excited about this new paper by @soiltycoon.bsky.social and @keiluweitlab.bsky.social . They elegantly confirm what we have proposed in our earlier papers(e.g. doi.org/10.1016/j.soilbio.2023.109259): the formation of temporarily anoxic microsites caused by root exudation.
NEW PAPER 🚨 Curious how plant root exudation and soil texture might interact to form dynamic anoxic microsites in the #rhizosphere, and what they might mean for the fate of soil #carbon, nutrient or contaminent in #soils? Check out @soiltycoon.bsky.social's new paper in SBB: doi.org/10.1016/j.so...
One week to go! Apply by Sept 17 for the Full Professor position in Soil Ecosystems and Global Change at #CeMESS at the University of Vienna.

A fun commentary with @christinakaiser.bsky.social inspired by a very cool paper in New Phyt by @fungidownunder.bsky.social et al. showing that EcM fungal functional traits affect soil C responses to elevated CO2. EcM species and traits really matter!

Ukraine is Europe!
We stand by Ukraine.
We will step up our support to Ukraine so that they can continue to fight back the agressor.
Today, it became clear that the free world needs a new leader. It’s up to us, Europeans, to take this challenge.
AGU urges the Trump administration to immediately renew U.S. federal commitment to climate science. The U.S. must restore critical climate science leadership for a secure, prosperous future for the country and the world.

Amazing!! 🤩
Our newest research in @nature.com
We built a robot (!) to track plant-fungal trade networks. By following half a million fungal highways & nutrient flows within them, we discovered how plants & fungi build hyper-efficient supply chains

Thanks to @stefangorka.bsky.social, Alex König, Erich Inselsbacher and others.

Fantastic work by first-author Dr. Julia Wiesenbauer, who also defended her PhD-thesis on Monday. Big congratulations! 😀🥳🎉. 5/6
Our results also emphasize the microbial feedback on root exudation rates. Compounds more readily taken up by microbes (such as OA in our case) can be released at higher rates by passive exudation, while compounds that accumulate at the exudation spot hinder their further (passive) exudation. 4/6
Our results challenge the prevailling assumption that sugars are readily available substrates for soil microbes. The observed microbial preference for organic acids (OA) may indicate a trade-off between rapid biomass growth and ATP yield per unit of substrate uptake. 3/6
Using reverse microdialysis in undisturbed soils we show that, compared to sugars, organic acids were i) removed quicker from the exudation spot, ii) preferentially respired by microbes and iii) led to the production of metabolic byproducts. 2/6
