Moose and caribou are two very important animals to both subsistence and sport hunting economies in Alaska. Their survival and reproduction is dependent on sufficient winter habitat and food sources, which may be threatened by climate change. During the winter, caribou eat lichens (organisms made up of algae and fungus) that grow on the snow-covered ground. Lichens will likely have a complex response to climate change, affected in different ways by factors like changing precipitation, wildfire, and competition with plants. For example, as temperatures warm, there will likely be less snow cover, exposing more of the lichen to caribou. Simultaneously, increased fire frequency could reduce lichen availability. Moose,...
