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 Editorial assistants have been replaced by a clunky, AI-enabled website that makes it harder to find and invite reviewers.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.

The bigger, the better! But honestly, I just have no idea of American units 😅 You can download the poster here: koiosjerome.direct.quickconnect.to:5001/sharing/CxrG... and I am more than happy to chat about it anytime 😃😃😃

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

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.

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 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
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.

🚨📃🧪 New paper out: "Impacts of diverse undersown cover crops on seasonal soil microbial properties". 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

#Sciencejob Alert! Scientific career, experience in leading #research projects & international network? Strong expertise in #forest #ecology and/or #soil #processes and/or #tree functions? 🌳 We are looking for a new head of the forest and soil ecology research unit: apply.refline.ch/273855/1726/...
The Swiss Federal Institute for Forest, Snow and Landscape Research WSL is part of the ETH Domain. Approximately 600 people work on the sustainable use and protection of the environment and on the handling of natural hazards.

Due to retirement, WSL invites for applications for the position as

Head of Research Unit Forest and Soil Ecology 90-100% (f/m/d)
You will lead and inspire an internationally recognized Research Unit comprising seven well-established, strong Research Groups and approximately 100 collaborators from around 20 countries. As a distinguished ecologist, you will play an important role in national and international projects focusing on forest or soil science. In the unit, you will integrate diverse research fields, while facilitating and promoting the scientific and strategic development of the research groups. By your extensive experience you will align the unit with WSL’s vision of fostering research for people and the environment in a changing world. You will engage with key forest authorities and expert organizations, ensuring impactful collaborations, and optimizing the knowledge transfer.
You are at an advanced stage of your scientific career, experienced in leading research teams and managing large projects. You possess a strong record as a Principal Investigator of significant initiatives, an outstanding publication portfolio, and a well-established international network. Deep expertise in forest ecology and/or soil processes and/or tree functions is assumed. You exemplify initiative, integration, and commitment, with proven skills in leadership, communication, and negotiation. Fluency in English and proficiency in at least one Swiss national language are required.

Thanks Nameer! Maowei deserves those congratulations way more than I do! 😅

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 🪲🍄🐛💚

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.
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.

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.
