quantifying resilience in ecology and evolution under global environmental change

Monitoring economic variables to infer ecosystem resilience

Strongly coupled socio-ecological systems propagate their effects and disturbances one to the other. This has been demonstrated in most studies of human management of common resources. In recent work, we show that indicators of decreasing resilience can also propagate from one system to the other. For example, an increasingly harvested fish stock might reflect its eroding resilience…

new job position

After 3 beautiful years in Spain, I am getting quite excited starting up a new postdoc position in Switzerland at ETH in Zurich. I will be part of a multidisciplinary program bringing together geneticists, ecologists, and biologists studying empirically and theoretically adaptation to a changing environment.

Hysteresis and Heteroskedasticity (early view papers)

Only a handful of studies demonstrate the existence of hysteresis in bistable systems. In a follow-up from our earlier work, we study the recovery trajectory of a light-stressed plankton population in a chemostat experiment (early view in Oikos). We find that reverse trajectories can be explained by hysteresis, time-delays and adaptive process, all of which pose…

Detecting tipping points in ecological networks

In this just published paper we develop a framework of detecting tipping points in the context of  mutualistic networks. Under a scenario of global environmental change that might affect species interactions we show how indicators of resilience could provide early warning in complex communities such as those represented by the network of interactions between plants and their animal mutualists. This work…

The use and misuse of resilience indicators as early warnings for regime shifts

Regime shifts have been a long sought theme of research in marine ecosystems. Controversies, new methods and alternative hypotheses on how to study and understand such marine regime shifts are summarized in the special issue of the Philosophical Transactions of the Royal Society on Marine regime shifts around the globe: theory, drivers and impacts that just appeared online. Thus,…

ASLO organized session: Regime shifts in lakes, rivers, and oceans

Together with David Seekel and Jessica Gephart, we are organizing a session on regime shifts in the upcoming American Society for Limnology & Oceanography conference in Granada, Spain in February 2015. The abstract submission is open with a deadline on the 10th of October 2014.

Learning about complex systems

A new experience attending a conference of another community for the first time. European Conference on Complex Systems in Lucca Italy. A mix of physicists, mathematicians and engineers. Probably few ecologists and biologists, although one of the complex systems track on the conference is about living systems. I hope I can get inspired and make…

Applying Resilience Thinking – conference preps

Just a week before the resilience conference 2014 in Montpellier a short brochure of our forthcoming book on “Principles for Building Resilience: Sustaining Ecosystem Services in Social-Ecological Systems” (Cambridge University Press, 2014) has become available by the Stockholm Resilience Center. The brochure summarizes the expanded treatment of resilience principles as we have discussed in an earlier paper “Towards principles for enhancing…

Spatial methods of early warnings for tipping points

Recently our paper on spatial indicators for critical transitions was published in PloS One. In this paper we summarize methods and create a flowchart for looking for indicators of upcoming transitions in spatial data. It is a natural follow-up paper from our previous work on methods for timeseries. The methods of the paper are now summarized in the spatial indicators section…

EWS package gets into WICI Data challenge finalists!

Our submission of an interactive visualization version of the earlywarnings R package for critical transitions in the Data Challenge competition organised by the Waterloo Institute for Complexity and Innovation got into the 4 finalists. Although we didn’t get the first place, the judges were very flattering and Leo Lahti and myself are really proud to have…
