Central Europe has seen unprecedented forest disturbances recently, but how are forests recovering? We surveyed disturbance hotspots in 10 countries 3-5 years after disturbance, finding ample tree regeneration and no signs of forest loss (median 4750 stems/ha), but... 1/2 doi.org/10.1111/gcb....

Forest interactions
Explore plant interactions in forest environments at all levels from micro- to macro-scales and across the whole spectrum of plant biology.

Fast-growing trees are set to dominate the #forests of the #future — but at a cost🌳
Our Nature Plants (@natplants.nature.com) study shows a global shift toward "sprinter" tree species, while slow-growing, functionally critical #trees face elevated #extinction risk. www.nature.com/articles/s41...
Global functional shifts in trees driven by alien naturalization and native extinction - Nature Plants
This study finds that native tree extinctions and alien naturalizations are pushing forests towards fast-growing, resource-demanding species. This global shift could affect carbon storage and ecosyste...

Thrilled to share our new paper on restoring tree diversity in Brazil’s Atlantic Forest!🌳

Our findings are encouraging: restoration shows high diversity, though old-growth-like composition needs more time.

Tree diversity is changing in the Amazon and Andes.

Belen Fadrique leads our analysis in @natecoevo.nature.com w/ 400 plots + 40 years of RAINFOR records.

Hot, drier, more fragmented forests are losing species. Many in the Andes + western Amazon are gaining them.
Very happy to share this new article on Andes-Amazon tree diversity change. We found that over the last 4 decades, tree richness changed differently across the Andes-Amazon regions. Thanks to the many researchers across the world who made this possible!

Keep reading!

Congrats - very cool thesis (pun intended 😜)! It's been fun following your science here. Looking forward to seeing what you get up to next!
New paper out!
We mapped forest recovery and its drivers in the Alps using multi-decadal fractional cover maps 🛰 and ecologically-informed recovery indicators 🌲.
New paper - and final PhD chapter of @lisa-mandl.bsky.social - published in Agricultural and Forest Meteorology. Using Landsat recovery and meteorological data, we show that thermal limitations constrain post-disturbance recovery success across forests of the European Alps: doi.org/10.1016/j.ag...
New paper in TREE: we propose a framework to think more clearly about the scale of climate exposure of organisms—and why mismatches between climate data and biology can mislead ecological inference.

Multiple anthropogenic stressors can negatively impact species but can a single stressor also have multiple, concurrent impacts? Here we show that light pollution creates several simultaneous impacts to the nocturnal movement ecology of a moth and a spider: tinyurl.com/5eku5bff (1/5)
Agroforestry can benefit the environment & production, so why isn't it more widely adopted?🌳🚜

Published!📖

This study shows that choosing the most effective restoration strategy for tropical forests at scale depends equally if not more on economic and logistical than ecological constraints.

🚨New paper!🚨 Models predict trees like beech will migrate north as climate warms, but rarely consider tree reproduction. Jessie shows these “refuges” are exactly where climate warming will disrupt seed production the most. They may not be such great climate refuges after all.
