Most vascular plants' distribition are in disequilibrium w/ current climates, w/ species ranges best predicted by climatic conditions 10-18 yrs before sampling, especially so for closed-canopy species 🌳🌳🌲🌲 ➡️ Lagging dynamics or microclimatic processes ? @natecoevo.nature.com shorturl.at/m2EOx

The future of Europe’s forest disturbance regimes– a thread. Tl, dr: Disturbances from wildfire, bark beetles & wind will continue to increase in the coming decades. Under unabated climate change disturbances could more than double by 2100. New paper out in @science.org doi.org/10.1126/scie...

New paper out today in Ecology Letters! In this synthesis we dive into the equilibrium assumption in ecology - why it's everywhere in ecological theory, the evidence for it in nature, when meeting the assumption is important, how to achieve it in empirical research, and more! tinyurl.com/yh6kyysm

New study finds where birds are declining most. High trend resolution data reveals complexity of bird population changes. “This is the first time we’ve had fine-scale information on population changes across such broad spatial extents and across entire ranges of species,” said Dr. Amanda Rodewald.
