quantifying resilience in ecology and evolution under global environmental change

PLoS One paper out!

The methodological paper that we worked on during the Santa Fe Institute workshop last October became available few weeks ago. It presents a suite of most developed methods for identifying early-warnings and provides clear step-by-step examples on how to apply them, in an attempt to offer a protocol to the uninitiated into the field. Most…

Model-based leading indicators for critical transitions

In a recent work with Tony Ives, we showed how modified linear models with time-varying parameters can be used to extract an indicator of instability for a time series that may be drifting towards a regime shift. The paper is available online in Ecosphere. The idea is simply that instead of fitting an autoregressive model…

Early Detection of Ecosystem Regime Shifts: A Multiple Method Evaluation for Management Application

The paper we were working on within the EUR-Oceans group for the Baltic Sea just appeared in PLoS One. We show for the first time how different methods for identifying regime shifts can be applied in the marine environment and how they can be interpreted. Hopefully this study will pave the way for same sort of…
