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

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).

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 😉

Etienne Lalechère @etiennelalechere.bsky.social · Aug 27

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.

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...

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...

Pleased to contribute some long(ish..) term data from Honduras as part of BioTIME 2.0: a terrific dataset ripe for all sorts of questions! onlinelibrary.wiley.com/doi/10.1111/...
Also another wake up call as to the massive biological data gaps across equatorial Africa (and the tropics in general)..

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.

Indeed, model validation comes from other analyses related to spatial autocorrelation and cross-validation (providing AUC, specificity and sensitivity).

Thanks for this comment, the wording is indeed confusing as looking for this distribution can provide information about potential unexpected patterns while there is no need for normality.
