The new Wiley journal review system is an absolute nightmare. Editorial assistants have been replaced by a clunky, AI-enabled website that makes it harder to find and invite reviewers. Associate editor workloads have increased. I'm not convinced the invitations to reviewers are even going through.

Seriously @globalchangebio.bsky.social & @wiley.com ?! 😡🧪🌍

Are you at @ESA2025 today? Come see my poster (263) about small consumer impacts on plant litter impacts on decomposition!

How climate shapes soil fungal traits Many soil microbes play a vital role in ecosystems, as they help plants access nutrients and water and assist in stress tolerance such as during drought and to defend against pathogens. One such group...

Our new global study led by @smriti-pehim-limbu.bsky.social is now out in @pnas.org. TLDR: Certain spore traits were linked to climate AND species range sizes! YES we can use traits to gain insight into env adaptations for microbes.

The study focuses on soil microbial communities. Benefits to the current crop are not presented in this study (see other studies from the experiment for this). Soils from plots with legume cover crops in the previous year increased AMF colonization in flax, suggesting benefits to following crops.

With Karoliina Huusko, @omsietio.bsky.social, Bernhard Schmid, Paula Thitz, Stephanie Gerin, @annaliisalaine.bsky.social, Annalea Lohila and @jheinons.bsky.social 6/6

Overall, diverse cover crops, particularly mixtures including legumes, sustained diverse and beneficial
fungal communities over winter, already after one
year of expeirment. Agricultural diversification using CCs may have positive impacts on the microbial communities. 5/6

Some highlights of many results
-vegetation and cover crop richness increased microbial biomass and microbial growth efficiency
-Cover crop richness increased AM fungal diversity while legumes suppressed fungal pathogens
-Legumes boosted next years crops association with beneficial AM fungi

For her PhD project, Rashmi characterized #TWINWINS bulk soil microbial communities across seasons, and used additional experiments to assess decomposition and legacy effects on AM colonization in a consecutive crop. 3/5

TWINWIN experiment design: (a) Three control (bare fallow, barley + herbivide, barley monoculture) and four undersowing treatments (diversity levels 1, 2, 4, and 8). (b) The eight undersown species /Trifolium hybridum, T. repens, T. pratense, Medicago sativa, Lolium multiflorum, Phleum pratense, Festuca arundinacea and Cichorium intybus) vary in rooting depth and N-fixation capacity, leading to four different ‘functional types’. (c) The undersown communities vary in richness and functional diversity (number of functional types of undersowns in a plot). (d) The 60 plots are arranged in four blocks.

#TWINWIN experiment is an agricultural biodiversity experiment, where the agricultural crop is undersown with cover crop species mixtures of varying species richness and functional composition to test if results from ecological biodiversity experiments can be applied to agricultural practices. 2/6

Rashmi Shrestha used the #TWINWIN experiment to show that undersowing crops with diverse plant mixtures, particularly including legumes has beneficial effects on soil microbial life and function 1/6

Despite having a smaller impact than plant species diversity, our findings show that a loss of arthropod or fungal consumers could destabilize plant communities. The small critter has important ecological roles, such contributing to ecological stability! Don't overlook it 🪲🍄🐛💚

Three panel figure that shows the links between diversity and community stability, as well as its components species stability and species asynchrony. The first panel shows that plant community stability increases with plant species richness equally across three levels of trophic complexity. The second panel shows a slight decrease of species stability with increasing plant species richness across three levels of trophic complexity. The third panel shows a strong increase of species asynchrony with plant species richness and this relationship is strongest at high trophic complexity and weakest at low trophic complexity.

Plant species richness increased biomass stability due to an increase in plant species asynchrony. Food web complexity alone did not impact community stability, but it further increased species asynchrony at high plant species richness.

Based on 14 years of plant biomass data from an experiment in which we manipulated plant species richness and presence of different consumer groups (insect herbivores, foliar fungal pathogens, soil oomycetes), we studied the joint impact of plant diversity and trophic complexity for stability.

Consumers Modulate Effects of Plant Diversity on Community Stability Biotic complexity, encompassing both competitive interactions within trophic levels and consumptive interactions among trophic levels, plays a fundamental role in maintaining ecosystem stability. Whil...

Co-reviews that some journals offer are a great way to start. And these guidelines www.britishecologicalsociety.org/wp-content/u...

My rejection rate is high, because the review request rate has been incredibly high lately. For every review, I turn down 4-5, simply because I can't do more. But that is n=1.

he Forest Soils and Biogeochemistry research unit investigates the impacts of climate change on soil biodiversity, soil functions, and ecosystem processes. The Biogeochemistry research group is looking from June 1, 2025 for a PhD student in Plant Water Relations Extreme droughts and heatwaves are increasingly threatening forest ecosystems in Switzerland, altering water availability and leading to tree stress. The DeepDrought project aims to advance our understanding of plant reliance on deep soil water and its role in mitigating drought stress. We are seeking a highly motivated PhD candidate to assess species-specific root water uptake patterns, dendrometer derived tree water deficit, and water use efficiency across Swiss forests using a combination of field observations, stable isotope analyses, and predictive modeling. The PhD candidate will focus on assessing plant reliance on deep soil water and will work closely with a multidisciplinary team across the Swiss Federal Institute for Forest, Snow, and Landscape Research (WSL), ETH Zürich, and the Technical University of Munich (TUM). The research will contribute to refining our understanding of plant-water interactions and enhancing climate resilience strategies for Swiss forests. You hold a master’s degree in environmental sciences, hydrology, ecology, forestry, or a related field. Experience with field data collection, particularly soil or plant water measurements, is an asset. A strong background in statistical analysis is desirable. Familiarity with stable isotope data, dendrometry, or soil hydrology is advantageous. Proficiency in programming languages such as R or Python for data analysis and modeling is required. You are highly motivated, independent, and eager to collaborate in an interdisciplinary research team. Excellent English skills are necessary, and knowledge of German or French is a plus but not essential.
