A new publication derived from the global BIODESERT project
12.04.2024
A new publication in Nature Plants derived from the global BIODESERT project shows how plant architecture and aridity shape the way in which shrubs affect biogeochemical cycling in drylands.
Congratulations to Katja, Liesbeth, Pierre, and Rafa!
New publication on asymmetry of leaves as an indicator of stress
11.04.2024
Our work on leaf fluctuating asymmetry as stress indicator has been accepted in Functional Ecology!
The bottom line: as much as we tweak published and our own data from many species and several stress gradients and stress experiments, FA has no relationship whatsoever with stress.
So we think it is time to abandon this idea in plants...
A metaanalysis about evolution of defenses in invasive plants
25.01.2024
Jinlong's and Katja's first manuscript about evolution of defenses in invasive plants, a metaanalysis, has been published in Ecology. https://doi.org/10.1002/ecy.4253
Congratulations!
First major DroughtNet publication
23.01.2024
Liesbeth and Katja are co-authors on a new manuscript just published in PNAS, which shows that extreme droughts will have larger impacts on grasslands and shrublands than previously thought. It is the first major DroughtNet publication - more to come! https://www.pnas.org/doi/10.1073/pnas.2309881120
New publication: Belowground niche partitioning is maintained under extreme drought
24.11.2023
In this study, scientists from our working group documented results suggesting that belowground niche partitioning could mitigate negative effects on diversity imposed by extreme drought under future climate: Ecology
Welcome Dr. Said M. Hassen
01.11.2023
Said, a plant ecologist from Ethiopia has joined the plant ecology group as PostDoc. He is from Debre Berhan University and his research fellowship is granted by the Alexander von Humboldt Foundation.
His research interests include the effects of climate change on the interactions between crop and weed species, and comparative characterization of germination and dormancy cycling between invasive weed populations and crops under future climate change. Welcome, Said!
New paper on dry adapted ecotypes of annual plants
01.08.2023
Katja has a new paper in Oikos accepted!
Jointly with the main author, Johannes Metz, the manuscript shows how dry adapted ecotypes of annual plants benefit more in dry years than wet adapted ones! https://onlinelibrary.wiley.com/doi/10.1111/oik.09806
Hierarchy reduces instability of competition networks
05.07.2023
In this new publication Franziska Koch, Katja Tielbörger and Korinna Allhoff investigate the structure and stability of competition networks. In their analysis, they combine mathematical models with empirical data on competition between bryozoans (moss animals) and show that hierarchy reduces the instability of these communities: https://www.nature.com/articles/s42003-023-05060-1
New paper on the impact of drought on plant ecosystems
12.06.2023
Rainout shelter experiments provide insight into the consequences of extreme drought on small spatial scales. Katja Tielbörger, Julia Schädle and Maximiliane Herberich report in their new paper on the response of the soil water and ecosystem productivity during and after an experimental drought: https://doi.org/10.1016/j.scitotenv.2023.164625
