Hence, I was very interested to see in Science this week a really nice experimental paper
Generic Indicators for Loss of Resilience Before a Tipping Point Leading to Population Collapse
by Lei Dai, Daan Vorselen, Kirill S. Korolev, and Jeff Gore
Theory predicts that the approach of catastrophic thresholds in natural systems (e.g., ecosystems, the climate) may result in an increasingly slow recovery from small perturbations, a phenomenon called critical slowing down. We used replicate laboratory populations of the budding yeast Saccharomyces cerevisiae for direct observation of critical slowing down before population collapse. We mapped the bifurcation diagram experimentally and found that the populations became more vulnerable to disturbance closer to the tipping point. Fluctuations of population density increased in size and duration near the tipping point, in agreement with the theory.Below is the "phase diagram" of the model.
Our results suggest that indicators of critical slowing down can provide advance warning of catastrophic thresholds and loss of resilience in a variety of dynamical systems.
