Adaptation prevents the extinction of Chlamydomonas reinhardtii under toxic beryllium.

ABSTRACT: The current biodiversity crisis represents a historic challenge for natural communities: the environmental rate of change exceeds the population's adaptation capability. Integrating both ecological and evolutionary responses is necessary to make reliable predictions regarding the loss of biodiversity. The race against extinction from an eco-evolutionary perspective is gaining importance in ecological risk assessment. Here, we performed a classical study of population dynamics-a fluctuation analysis-and evaluated the results from an adaption perspective. Fluctuation analysis, widely used with microorganisms, is an effective empirical procedure to study adaptation under strong selective pressure because it incorporates the factors that influence demographic, genetic and environmental changes
