The Impact of Population Bottlenecks on Microbial Adaptation

Population bottlenecks—sudden, severe reductions in population size—are ubiquitous in nature. Because of their critical implications for conservation genetics, the effects of population bottlenecks on the loss of genetic diversity have been well studied. Bottlenecks also have important implications...

Description
Summary:Population bottlenecks—sudden, severe reductions in population size—are ubiquitous in nature. Because of their critical implications for conservation genetics, the effects of population bottlenecks on the loss of genetic diversity have been well studied. Bottlenecks also have important implications for adaptation, however, and these effects have been addressed more recently, typically in microbial populations. In this short review, we survey both experimental and theoretical work describing the impact of population bottlenecks on microbial adaptation. Focusing on theoretical contributions, we highlight emerging insights and conclude with several open questions of interest in the field.
