Big thanks to you Xavier, and to all the people for attending and asking great questions! It's been great to be back at the EBD @ebdonana.bsky.social !

This is an open-access, reproducible project, GuadalShiftR, github.com/palmaraz/Gua..., also in Zenodo, zenodo.org/records/1063.... Developed @ICMAN_CSIC, @ebdonana, @CSIC.

Our paper is published in the Special Issue ‘Non-equilibrium perspectives in biological conservation’ sciencedirect.com/journal/biol.... It emerged from a long-held intuition, and pushed forward
@ICMAN_CSIC by joining forces with @drAndyGreen @ebdonana

Our study thus provides an empirical example of a catastrophic bifurcation triggered by a tipping point in the dynamics of a threatened vertebrate community: this highlights the relevance of history and multi-stability in explaining current patterns in biological conservation.

A stochastic cusp catastrophe model suggests that the persistence of cold and dry conditions in the wintering areas, and the warm and wet conditions in the breeding grounds, modulated local conditions and induced hysteresis through behavioral shifts to alternative wintering sites

And we uncover the likely cause behind this persistent regime shift: the explosion of Mt. Pinatubo in Philippines in 1991 triggered an anomalous, but transient period of cold and dry winters in southern Europe, a harsh environment for wintering migrating birds

We now show that both periods are equally stable dynamically. However, structural stability, as measured through a new metric, the Bayesian posterior probability of feasibility, declined: the community became more fragile through time

In a previous paper (besjournals.onlinelibrary.wiley.com/doi/full/10....), we were intrigued by a regime shift to low fluctuating population levels in waterfowl community abundance starting in 1991. Even today, most species have not recovered their pre-1991 abundance levels!

Doñana is an ever-changing ecosystem varying wildly in the extension of flooded surface, both within and among years, at all time scales. This is a key to its once-thriving biodiversity. Worryingly, this no longer seems to be the case (e.g., link.springer.com/article/10.1...)
