Sea turtles are vulnerable to climate change since their reproductive output is influenced by incubating temperatures, with warmer temperatures causing lower hatching success and increased feminization of embryos. Their ability to cope with projected increases in ambient temperatures will depend on their capacity to adapt to shifts in climatic regimes. Here, we assessed the extent to which phenological shifts could mitigate im...

Treelines in Alaska are advancing in elevation and latitude because of climate warming, which is expanding the habitat available for boreal wildlife species, including snowshoe hares ( Lepus americanus ). Snowshoe hares are already present in tall shrub communities beyond treeline and are the main browser of white spruce ( Picea glauca ), the dominant tree species at treeline in Alaska. We investigated the processes involved i...
