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 😉

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.

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).

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

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.

📢New paper!! 📢using #BioTIME #timeseries we showed that faster rates of #turnover in community composition were associated with faster rates of #temperature #change across biomes, for both cooling & warming + microclimate availability & human impacts modulate these responses

Let me guide you through what we did to test time lag dynamics in species distribution models #SDMs of 🌲🌳 birds in 🇪🇺 A 🧵

🔥 Just out 🔥 our paper featuring a method to account for disequilibrium dynamics & time lags in species distribution model #SDM is published in Ecology Letters ⬇️ It outperforms traditional SDMs for 95% of the 92 European forest 🦅 species we tested

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.
