Selection in environments that vary through time at different scales

Article Abstract:

Experimental evolution in the unicellular chlorophyte Chlamydomonas reinhardtii is discussed as it relates to adaptation and natural selection in environments that vary to a different degree at different times. Selection in variable environments was found to act on the mean performance in each environment, not on the variance in performance across environments, and the cost of being a generalist was a small one.

Variability levels, population size and structure of American and European Drosophila montana populations

Article Abstract:

American and European Drosophila montana populations have been studied relative to population size and structure. The level of silent site variability was significantly lower in the European population than in the American one. A selective sweep at or near fu in the former population.
