😂 Yep! But it’s the current @ecography.bsky.social cover, not my choice — snow leopards might be the perfect bait to get people reading plant papers 🐆🌿😄

A globally consistent scaling relationship reveals stabilizing effects of dominant species in plant communities Despite extensive research, stabilizing mechanisms in ecosystems remain uncertain. Taylor's power law (TPL) is a pervasive ecological pattern that describes how variance scales with mean abundance (σ....

All coexisting species ☘️🌿🌾 follow a single power function 📈 linking their temporal variability to their mean abundance 🤯 — 💥Taylor’s power law💥. This exceptionally strong law in community #ecology shows how dominants play a key role in stabilizing ecosystems worldwide 🌍🌐

Does greater biodiversity always increase ecosystem functioning? I used to think so, but now I'm not so sure.

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.

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

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

I am very happy to spend some weeks visiting the @plantecolcb.bsky.social group! After reading a lot of papers from this experiment I finally have the opportunity to visit the place and meet the people 😊

A nice review to add to the next steps in #TraitBaesdEcology literature - "Raunkiæran shortfalls: Challenges and perspectives in trait‐based ecology" 🌐🧪🌾https://esajournals.onlinelibrary.wiley.com/doi/abs/10.1002/ecm.70018

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.

Trait-based #ecology has flourished, but key limitations still hinder progress. We identify 8 major shortfalls, from trait definitions 📏 to ecosystem scaling 🔄🌐, and propose paths forward for a more robust and integrative trait-based framework.
