Models for Physiological and Genetic Adaptation to Variable Environments
The challenge of a temporally or spatially varying environment to a population can be met at the individual level, at the population level, or at both. Individual organisms may adjust physiologically to the entire range of conditions. Populations may systematically change in gene frequencies (where the environmental variation is sufficiently predictable). Likewise, both physiological and genetic changes may occur in space and time.
