We analyze mathematical models to examine how the genetic basis of fitness affects the
persistence of a population suddenly encountering a harsh environment where it would go …

Understanding population responses to novel environments is a central concern of both
evolutionary biology and ecology (Maynard Smith 1989; Bradshaw 1991; Hoffman and …

Because of the ubiquity of genetic variation for quantitative traits, virtually all populations
have some capacity to respond evolutionarily to selective challenges. However, natural …

Environmental variation is commonplace, but unpredictable. Populations that encounter a
deleterious environment can sometimes avoid extinction by rapid evolutionary adaptation …

What factors shape the evolution of invasive populations? Recent theoretical and empirical
studies suggest that an evolutionary history of disturbance might be an important factor. This …

We investigate the evolutionary rescue of a microbial population in a gradually deteriorating
environment, through a combination of analytical calculations and stochastic simulations …

Evolutionary rescue describes a situation where adaptive evolution prevents the extinction
of a population facing a stressing environment. Models of evolutionary rescue could in …

Theories of adaptation typically ignore the effect of environmental change on population
size. But some environmental challenges—challenges to which populations must adapt …

Novel environments can cause strong selection and rapid adaptation. The genetic basis of
such rapid adaptation tends to be composed of few loci of large effect. Current theory …

No environment is constant over time, and environmental fluctuations impact the outcome of
evolutionary dynamics. Survival of a population not adapted to some environmental …
