Snowshoe hares (Lepus americanus) maintain seasonal camouflage by molting to a white
winter coat, but some hares remain brown during the winter in regions with low snow cover …

The genetic basis of adaptive traits has rarely been used to predict future vulnerability of
populations to climate change. We show that light versus dark seasonal pelage in white …

As duration of snow cover decreases owing to climate change, species undergoing
seasonal colour moults can become colour mismatched with their background. The …

Most examples of seasonal mismatches in phenology span multiple trophic levels, with
timing of animal reproduction, hibernation, or migration becoming detached from peak food …

Hybridization may often be an important source of adaptive variation, but the extent and long-
term impacts of introgression have seldom been evaluated in the phylogenetic context of a …

Adaptation is a central focus of biology, although it can be difficult to identify both the
strength and agent of selection and the underlying molecular mechanisms causing change …

Anthropogenic climate change has created myriad stressors that threaten to cause local
extinctions if wild populations fail to adapt to novel conditions. We studied individual and …

Maintenance of biodiversity in a rapidly changing climate will depend on the efficacy of
evolutionary rescue, whereby population declines due to abrupt environmental change are …

Conservation for species impacted by climate change often occurs at scales impractical for
local land managers. Snowshoe hares (Lepus americanus) are one of the most well …

The transformation of wild animals into domestic ones available for human nutrition was a
key prerequisite for modern human societies. However, no other domestic species has had …
