Human activities affect evolutionary ecology of wildlife

Alteration of habitats by human activities leads to degraded or novel environments that animals must physiologically and behaviourally react to. These altered landscapes can have profound sub-lethal consequences for individuals, and can affect traits that are important for fitness.
Forest resource extraction and urbanization are two ways that humans alter natural landscapes. Using the eastern chipmunk (Tamias striatus) and the raccoon (Procyon lotor) as models, we examined the effects of resource extraction (logging) and urbanization on traits including behaviour, base-line glucocorticoids and energy metabolism. Habitats altered by human activities do not have a universally negative effects on individuals, suggesting the complex effects of human activities on biodiversity.
