New paper out in Soil Biology and Biochemistry! “Eco-evolutionary controls of microbial extracellular enzyme production in soils” doi.org/10.1016/j.so... Work on this paper began 5 years ago when I first started my PhD and it has taken many turns since then. Very happy to see it out eventually! 😊

📢 Multiple #postdocs @lsce-ipsl.bsky.social on modeling #permafrost and #peatland greenhouse gas emissions and abrupt changes (deadline: July 10) Positions are funded by @erc.europa.eu project: Northern Peatlands in the face of climate warming and abrupt changes (CLIMPEAT)

The moisture optimum of microbial respiration is higher in intact than in sieved soils often used for model calibration. As a consequence, our models can under- (over-)estimate respiration in wet (dry) climates--see Elsa Coucheney's paper: doi.org/10.1016/j.ge...

Is the temperature-dependence of soil respiration Q10 similar during soil drying and rewetting? www.sciencedirect.com/science/arti...

... and speaking of @tellusjournal.bsky.social , I am happy our first article in Tellus was just published: tellusjournal.org/articles/10.... Here we use stoichiometric models to show that litter decomposers can compensate nutrient imbalances by recycling nitrogen--no need to lower CUE

Our Editorial Board gathered at #EGU26! Proof that behind every careful review, thoughtful decision, and late-night manuscript discussion, there are actual smiling humans (yes, really 😄). We are for scientists, by scientists — and occasionally with coffee, laughter, and a group photo to prove it.

If your #EGU26 schedule is not full yet, have a look at these presentations from our group: - Eco-evolutionary models meetingorganizer.copernicus.org/EGU26/EGU26-... by @erikschwarz.bsky.social - C-N stoichiometry meetingorganizer.copernicus.org/EGU26/EGU26-... by @majasiegenthaler.bsky.social

A new era for Tellus! 🌍 The re-launched journal presents the first scientific publications — spanning atmospheric processes, ocean change, and emerging climate research. Read more below.

Best way to start your #EGU26 week? Monday 8:30 ➡️ BG1.11 “Functional diversity in motion” chaired by @elsa-abs.bsky.social, @bopplaurent.bsky.social @lisawingate.bsky.social, @manzonilab.bsky.social

Since last year, Ilona Riipinen and I @stockholm-uni.bsky.social @bolincentre.bsky.social have been working with an amazing team of senior editors to re-launch the journal Tellus @tellusjournal.bsky.social. We are making it our dream journal to publish fundamental science on any of the 🌍 spheres.

Tellus@tellusjournal.bsky.social · 4mo ago

The first publication from the relaunched Tellus journal is now available! This editorial outlines the journal’s scope and direction as a platform for interdisciplinary Earth system science, with a focus on scientific quality, openness, and community-oriented publishing. ⬇️

Happy to see that our paper on the role of microbial community composition on decomposition rates in forest soils is finally out!

Crop rotations have been around for 1000s of years--great for sustainability and climate adaptation, but can they deliver all the food we need? In short, yes! and even more calories, proteins and fats than cereal monocultures: www.nature.com/articles/s43...

While the benefits of crop diversity are known, doubts remain as to whether replacing cereals in rotations reduces nutrient production. A comparison of 16 long-term field experiments across Europe sho...

Soil microbes grow, respire, die. Because their biomass eventually becomes necromass, and necromass can be stabilized in soil, growth rate emerges as a powerful predictor of soil carbon: www.nature.com/articles/s41...

Microbial carbon use efficiency is a strong predictor of soil organic carbon stocks. Here the authors reveal that the microbial growth rate is a more reliable and informative predictor, and that model...

Efficiencies are sometimes tricky to interpret. Here we show how the observed increase in efficiency of water use (iWUE) by trees does not necessarily translate into higher tree growth--drier air or drier soil limit growth despite high iWUE. Thanks Quan Zhang for leading this project!

Pieter Zuidema@pieterzuidema.bsky.social · 8mo ago

Extra CO2 stimulates #photosynthesis of trees and reduces water losses through transpiration. But does that stimulate growth of #tree stems? Our paper today in NatClimateChange led by Quan Zhang uses theory & data to show that strong growth stimulation is unlikely.🌎🌐🍁 www.nature.com/articles/s41...
