We are developing a new Forest Water Stress Index (FWSI) based on tree hydraulic functioning. More information: herve.cochard.free.fr/ISF_EN.html

🧵1/ New paper out in @ecography.bsky.social ! 🌍🌳 We looked at temperate deciduous forests across North America, West Eurasia, and East Eurasia, three regions that share ancient roots but have been separated for millions of years. What does that long breakup mean for today’s biodiversity?

I’m happy to share my first article #Biological Invasions We show that Rhododendron ponticum alters carbon transformation in forest soils mainly through its recalcitrant litter rather than microclimate changes. These effects evolve over time highlighting the importance of invasion age. rdcu.be/e1Fek

The niche concept explains where species can persist—but not always why. Integrating old, near forgotten ideas with modern demography, the Demographic Niche Concept provides a process-based foundation for understanding niches and distributions. nsojournals.onlinelibrary.wiley.com/doi/full/10....
Show Post📜New Paper📜@ecography.bsky.social Species distributions aren’t just about where species occur, but how survival, reproduction and development vary across environments. We formalise the Demographic Niche Concept to link niche theory and demography. nsojournals.onlinelibrary.wiley.com/doi/10.1002/...
