Excited and proud to see this paper published! Another example of a fruitful (and fun!) collaboration of #root scientists.
Thanks to the leading team, to @newphyt.bsky.social and to many global scientific networks and experiments for making it possible.

We aim to better understand biodiversity-disease relationships by studying the role of root traits, plant community composition as well as the interaction with mycorrhizal fungi for pathogen dynamics in soil and roots, with a focus on grassland systems.

There are three (!) open vacancies (2 PhD, 1 PostDoc) to join the our team in the ERC project of Liesje Mommer at Wageningen University! Consider applying if you are interested in root fungal pathogens and using bioassays in the lab, fieldwork in large biodiversity experiments or modelling.

This study is the result of a workshop series initiated by Alexandra Weigelt from @agwirthweigelt.bsky.social and Liesje Mommer, and was supported by the New Phytologist Foundation. Led by Kathryn Barry and myself, with a fantastic group effort from many collaborators and co-authors, including

However, our study also raises new questions about the role of a potential mismatch in above- and belowground abundance of plants and its role for trait coordination based on CWM traits.
henneckejustus.bsky.social
This suggests that changes in species (and hence functional) composition, for example due to effects of global change, but also targeted approaches in restoration, can lead to very relevant changes in functioning at the plant- and ecosystem level.

While past research tended to focus on traits of the 'fast-slow' conservation gradient (root nitrogen content and root tissue density), we show that the morphological and anatomical traits of the collaboration gradient (root diameter and specific root length) are of similar importance.
henneckejustus.bsky.social
We found that the coordination of community-weighted root traits (from the GRooT database) deviated from the root economics space and the coordination at the species-level. Nonetheless, these CWM traits were actually related to many ecosystem functions of carbon and nutrient cycling.
henneckejustus.bsky.social
We developed and tested hypotheses on how fine root traits of the root economics space relate to ecosystem functioning in grasslands and forests, and experimental and observational systems (such as the Jena Experiment, the Biodiversity Exploratories, BEF-China, Cedar Creek, NEON and others).

Using precise spatial and temporal analysis, researchers in Science provide insight into how bacteria around the root interact both with the plant and with each other.

A confocal microscopy image shows root-colonizing bacteria clustering around an emerging lateral root, where localized glutamine leakage induces spatially confined reporter activity.

🌼 In open biomes, plant height can be unrelated to plant age. This study assesses plant age by counting annual growth rings within sections of stem base🧪🌎

New research just dropped! Revisiting Paradigms Related to Root Hydraulic Limitation Under Drought is now available—challenging classic hydraulic-fuse models and outdated assumptions about root embolism, xylem safety-efficiency trade-offs, and ABA signalling. doi.org/10.1007/124_...

Shannon's H, Simpson's D, and Pielou's J are useless in ecology. Fitting data with a compound abundance distribution based on the geometric series is a better way to quantify variation – and to estimate species richness. New paper in Ecology Letters.
