Severe environmental change can put a population at risk of extinction. However, the population can be 'rescued' by adaptive evolution if it adapts rapidly enough to the new conditions. Evolutionary rescue is thus a race between population decline and adaptive evolution with the additional complication that evolution and demography interact with each other. Mathematical models are key in gaining insight into the factors that influence the outcome and in making predictions for specific systems. In this talk, I will discuss what determines the probability of rescue, highlight the role of stochasticity, and introduce a classic modeling framework. I will then show applications to bacterial adaptation and the evolution of antibiotic resistance, which constitutes an instance of undesired evolutionary rescue.
