A new publication led by Ondra, now published in @jvegsci.bsky.social is the result of fieldwork by almost our entire working group. We examined the intraspecific trait variability of 15 Carex species across South Bohemia.

In our new article with Rui-Ling Liu and Wen-Yong Guo in J. Ecol., we quantified how plant strategy scores derived from leaf traits (Pierce method) correlate with other plant traits and plant environmental preferences.

Global positive correlation between root diameter and seed size, driven by dual roles of arbuscular mycorrhiza in phosphorus uptake and pathogen defence.

Last week’s campaign combined tech & teamwork!
Multispectral drone flights by Leyre Pedrós Pla (PhD student of Francesco de Bello) + trait sampling across all Prachatice grassland sites = 710 leaf samples processed in 2 days. Big thanks to the whole team! @jsegrestin.bsky.social #RemoteSensing

Jules Segrestin @jsegrestin.bsky.social · Jul 8

Last week, we hosted Leyre (PhD w/ Francesco) who flew a drone equipped with a #multispectral camera over all our multi-site diversity plots 🚁

At the same time, we measured plant #traits across the entire gradient and… processed 710 leaf samples in just 2 days 😅

An intense but rewarding campaign 💪

🌿 Testing the ‘afterlife' effect 👻 within species 🌿

Do Carex populations from different environments decompose differently? 🍂

✅ Yes – different populations had different decomposability
🤏 But species identity mattered much more
❗ And leaf #traits didn’t reliably predict decay rates

Szilvia Neumann @szilviamneumann.bsky.social · Jun 13

So excited to see the first chapter of my PhD published! 🎉

We conducted a leaf decomposition experiment on closely related Carex species, and investigated the extent of trait differences within and between species 🍃🍂

Group of "trait ecologists" published a large paper on the state of the art of the discipline in Ecological Monographs. doi.org/10.1002/ecm.... - There are four authors in the team from our group, including the leading author, Francesco de Bello.

Scheme representing and connecting the eight SFs (shortfalls) considered in this review. See also Table 1. We distinguishtraits sensu stricto from specific response functions (SRFs) and specific effect functions (SEFs) as, respectively, the potential responsiveness ofspecies to given environmental conditions and the potential effect on given ecosystem functions. For graphical purposes, we representdifferent species (from 1 to n) belonging to different branches of a (unresolved) phylogenetic tree. We represent trait variability acrossindividuals within a species as black circles with varying sizes depending on their values. A similar approach is used to represent SRF,fitness, and SEF values (respectively gray circles, gray squares, and white circles). Abiotic and biotic filtering is represented as a dotted lineby which certain organisms either become part of, or not, of a local community, based on their trait values. The overlap between trait andSEF values (represented by the mathematical overlap symbol) controls community effects on ecosystems and other trophic levels. The studyof these connections across multiple regions (represented as overlapping images of the scheme for “Region” 1 to n) is the basis of the globalscaling related to SF 8. The drawing of the world was taken from Freepik.com.

It’s the result of a massive collaborative effort to establish & maintain the removal experiment. Collecting root data was no easy task – months of hard work went into processing all the samples. Huge thanks to the team for making it happen! 🌱

Process of collecting root samples using ingrowth cores for our scientific study. It shows the ingrowth cores (tubes used to isolate and measure root growth), a close-up of a core containing roots and soil, and the storage of collected root core samples (tubes filled with soil and roots) in a freezer.
