So pleased to see this out after a massive team effort! We did (to our knowledge) the first complete meta-analysis of biotic resistance since Levine et al. 2004, pairing this with models exploring the eco-evolutionary dynamics of biotic resistance! Dive in ⬇️ onlinelibrary.wiley.com/doi/10.1002/...

Further, nutrient addition alters resistance & resilience indirectly by reducing species richness and increasing dominance. In summary: A combination of richness, dominance and evenness are needed for stability during extreme climates, but all of them together cannot be maximized simultaneously.

With this unique dataset, we found that - species richness is important for resistance to extreme dry events - the abundance of dominant species is important for resistance to extreme wet events - evenness is important for resilience under unfertilized conditions

Together these results show that bottom-up and top-down factors interact with necromass chemistry to govern necromass decay. They highlight the critical role of plants in coupling aboveground fungal communities with belowground decomposer communities & their collective influence on soil C cycling.

Seraina Cappelli @serainacappelli.bsky.social · 19/03/2026
The decomposition of low quality necromass was primarily driven by treatment-induced shifts in abiotic soil conditions (moisture, pH), whereas high quality necromass decomposition was governed by biotic drivers (mould & yeast relative abundance, C3 grass abundance).

Seraina Cappelli @serainacappelli.bsky.social · 19/03/2026
Fertilization increased fungal abundance, while fungicide promoted bacterial abundance on high-quality necromass.
This is figure 5 from the published manuscript. It shows the log response ratios (LRR, response to fungicide and fertilizer treatment) of bacterial (panel A) and fungal (panel B) sequence abundance at 6 and 32 days after litter bag placement in the field. Fungal abundance on high quality litter increased with fertilizer at 6 days after placement, and bacterial abundance on high quality litter increased with fungicide and fungicide+fertilizer treatment at 6 days after placement.

Seraina Cappelli @serainacappelli.bsky.social · 19/03/2026
As for plant litter, fertilization generally accelerated early-stage necromass decomposition, but this was surprisingly not enhanced by fungicide application.
Figure 3 from the published manuscritp. It shows the proportion of high and low quality necromass remaining in litterbags at different time points up to 60 days after placement of litterbags in the field (panel a). This is shown for different treatments (with and without fungicide, with and without fertilizer). In panel B and C, the decomposition rates k and the slow pool size A response ratio to treatments are shown by necromass type (high and low quality). The results in this figure described in the results section of the manuscript: "Treatment effects on fungal necromass decomposition were most pronounced during the early phase of decomposition (Fig. 3A). Fertilization accelerated the decay of the fast pool but only in control
plots, in which necromass k increased from 0.10 ± 0.01 day⁻1 to 0.13 ± 0.01 day⁻1. On average, the decay rate of Cladosporium was nearly double that of Hyaloscypha and showed greater responsiveness to treatments overall (Fig. 3B, LRR > 0). Specifically, Cladosporium decay
was accelerated by fertilizer, fungicide, and their combination. However, when fungicide and fertilizer were applied together, decay rates were no
higher than under either treatment alone (Fig. 3B). The size of the slow pool (A), which represents the proportion of necromass remaining after the initial fast pool decays, exhibited a complex three-way interaction between substrate quality, fungicide, and fertilization. In unfertilized plots, fungicide application significantly increased the proportion
of Cladosporium necromass that persisted in the slow phase from 0.18 ± 0.01 to 0.25 ± 0.02 (Fig. 3C), making its long-term persistence comparable to that of the low quality Hyaloscypha necromass (0.25 ± 0.04; averaged across all treatments). In fertilized plots, fungicide failed
to increase the slow pool size, which was similar between fungicide treated (0.20 ± 0.02) and control plots (0.20 ± 0.01)."

For this, she decomposed fungal necromass of varying quality in a consumer removal experiment at Cedar Creek, where we manipulated the presence of foliar fungal pathogens and nutrient availability.

Here, Katie investigated the role of fungi for carbon cycling, as input to soils in the form of fungal necromass, as saprotrophs living on soil organic carbon and as plant pathogens controlling the availability of plant derived soil carbon and how their role varied under increased nutrient supply

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.

#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.

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.

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.
