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.

Thanks for this great excursion to the rewilding moles! The winter light made the landscape even more beautiful.

Wonderful ##TIBS2026 excursion to the Mols #rewilding site this Saturday 🐎🌿❄️🐂🌳☀️ Links to our research on the sites in the comments (more is on the way!) #restoration #ecology #megafauna ➡️

Out now! 🌿🎙️ In this month's episode of #InsideBiodiversity, Prof Marten Scheffer explains critical transitions and tipping points.

Together with iDiv's Dr Volker Hahn, he explores whether local tipping points can be scaled up to a 🌍 biospheric planetary boundary.

This is truly necessary work, thank you for doing it, and congrats, it is a very useful piece for the community.

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

Our opinion paper on embracing #disequilibrium dynamics to model #biodiversity trends is now published in the latest issue of Trends in Ecology & Evolution

Very proud & glad to be part of this amazing work led by Étienne on the relevance of lagging dynamics in biotic responses to environmental conditions 🦉🦇🦔🦌🌱🌾🪻🍀🌳🌲

If you interested in modeling species ranges or biodiversity patters in space & time, our paradigm shift should be of interest to you 😉

This opinion piece introduce a new conceptual framework but also a methodology to capture the delayed effects of biodiversity drivers (take a look this is model-agnostic 😊, i.e. it does not depend on the modelling approach).

Biodiversity doesn’t respond instantly to its driver, yet most assessments assume it does. 🚨

The paradigm shift we propose in considers multiple trajectories of long-term environmental changes and disturbance events that cumulate and push biodiversity into a quasi-permanent non-equilibrium state.

Do biodiversity drivers have no long-term effects?🚨Still the dominant assumption.

We propose a paradigm shift in Trends in Ecol & Evol:🔗 doi.org/10.1016/j.tr...

Coupled, decoupled, and abrupt responses of vegetation to climate across timescales Climate and ecosystem dynamics vary across timescales, but research into climate-driven vegetation dynamics usually focuses on singular timescales. We developed a spectral analysis–based approach that...

Vegetation might not be able to keep up with current rates of environmental change, given data from the pollen fossil record. Fun doing this work with David Fastovich in the lead, but sobering www.science.org/doi/10.1126/...

Taylor’s law predicts unprecedented pulses of forest disturbance under global change - Nature Communications Large pulses of disturbance have been observed globally in response to climate change. Using Taylor’s Law, the authors show that those pulses were not unpredictable but expected given a strong scaling...

As the mean rate of forest disturbance is increasing, so does its temporal variance. Proof that Taylor's law also applies to disturbance ecology, and a warning of more severe future extremes. Paper led by @corneliussenf.bsky.social w/ @tommaso-jucker.bsky.social www.nature.com/articles/s41...

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.
