The resilience of coastal wetlands – an optimistic look to the future

Loss estimates for coastal wetlands by the end of the century are severe. Coastal communities depend on these critical systems for the services they provide. With rising sea levels and encroaching human populations, the fate of coastal wetlands remains uncertain. However, a new study suggests that there is hope for these habitats even if the direst rates of sea-level rise occur. As long as coastal wetlands are given space to build upwards and migrate inland, we could preserve these habitats and the benefits they provide.

Winter coat color determines species survival in a changing climate

We’ve all seen pictures of a bright white arctic fox or snowshoe hare in a snowy landscape. But did you know, these same animals actually have brown coats during the summer? The ability of animals to change their seasonal coat color enables them to camouflage themselves against the landscape year round. A decrease in the duration of winter snow cover is one of the most widespread signals of climate change. Without snow, bright white arctic foxes and snowshoe hares will be obvious to predators and have decreased survival. A recent study reports that populations that have a mix of individuals with either brown or white winter coats may be better able to adapt and persist during this age of climate change.
