... tolerance, and suggest that natural selection is shaping the structure of the hybrid zone across the Gulf of Maine. Our limited genomic sampling does not eliminate the strong possibility that mito-nuclear co-adaptation may play a role in the differences in thermal phenotypes documented here. Linkage between...

... manipulation energy expenditure natural selection oxygen consumption In birds, the annual peak of energy demand has long been thought to occur when parents provision their offspring with food during the nestling phase. This has lead to the idea that selection on clutch size takes place during...

...Martin E. Feder SUMMARY A longstanding challenge for biologists has been to explain not just how organisms are adapted to diverse environments, but how these adaptations arise. Although natural selection is clearly sufficient to act on heritable variation, is this heritable variation sufficient...

Ecological interactions mediated through phenotypic plasticity are ubiquitous in nature, and the potential evolutionary consequences of these interactions illustrate the complexity inherent in understanding evolution in a community context. e...

BMR was measured six times over a 2.5 year period in captive zebra finches. BMR residuals showed significant repeatabilities over...
