Spatial Control of Microbial Pesticide Degradation in Soil: A Model-Based Scenario Analysis Microbial pesticide degraders are heterogeneously distributed in soil. Their spatial aggregation at the millimeter scale reduces the frequency of degrader–pesticide encounter and can introduce transpo...

Finally, a look at spatial heterogeneities using scale transition theory--if microbes are far from their substrate, decomposition rates slow down (case study on pesticide degradation): doi.org/10.1021/acs....

When and why microbial-explicit soil organic carbon models can be unstable Abstract. Microbial-explicit soil organic carbon (SOC) cycling models are increasingly being recognized for their advantages over linear models in describing SOC dynamics. These models are known to ex...

While applying eco-evolutionary optimization, Erik also found that positive feedbacks in microbial models can cause microbial extinction. You can check if your model fulfills mathematical criteria for stable behavior here: doi.org/10.5194/bg-2...

Eco‐Evolutionary Optimality in Soil Organic Matter Models Optimization approaches based on fundamental eco-evolutionary principles (EEO approaches) can increase the realism and generality of microbial-explicit soil organic matter (SOM) models—yet, these app....

In his thesis, Erik studied how eco-evolutionary processes can be included in soil carbon cycling models, and how microbial interactions modulate such processes. For a synthesis of current approaches including theory and pedagogic examples: doi.org/10.1111/ele....

Happy to post the news that @erikschwarz.bsky.social has successfully defended his PhD thesis “Microbial ecology in soil carbon models". Opponent: Sergey Blagodatsky; evaluators: Nadja Ray, Katharina Meurer, Jan Bengtsson. Congratulations Dr. Schwarz! 🎉🎊 (photo by Abigail Robinson)

Main conclusion: "Our analysis shows no trade-off between functionally rich rotations and food production or agricultural land expansion." Study led by Giulia Vico and her team at SLU, using >34,500 yield observations from 16 long-term experiments across Europe

Functionally rich crop rotations increase calorie and macronutrient outputs across Europe - Nature Food 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...

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...

YouTube video by European Geosciences Union EGU WEBINARS: Mental Health in Academia: Obstacles, Advocacy and Inclusion

The @egubg.bsky.social Early Career Scientists team invited me to share my thoughts about #AcademicMentalHealth and what to do about the ongoing crisis. Some folks wonder: I am an Earth System scientist, why do I keep talking about mental health?

Share your comments on NCAR with NSF Tell NSF the future that you want for NCAR by 13 March

One month left to submit a comment to NSF about their threat to dismantle NCAR. AGU has a great tool, below. This was easy to do and you can help flood the NSF inbox with messages about how important is it to keep NCAR together!

Microbial growth rate is a stronger predictor of soil organic carbon than carbon use efficiency - Nature Ecology & Evolution 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...

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...

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!
