Are Isle Royale's Wolves Chasing Extinction?

Sarah Crespi recently conducted an interview with Christine Mlot on Science Magazine about the current condition of the wolves living on Isle Royale. Isle Royale is an island just north of the Upper Peninsula in Michigan and is the habitat and breeding ground for these wolves. However, as of recently the numbers have been going down due to two factors. These two factors are the canine parvovirus infection and most importantly climate change. During the winter, the lake freezes over and wolves actually come from Ontario, Canada and keep the reproduction of wolves going. As of recently the lake has not been freezing over and this has affected the wolf population. Mlot states that the last freeze over happened in 2008 and these freeze overs are vital to the existence of these wolves. Now, the question is whether or not to intervene in the situation presented at hand by placing wolves in the area in order to increase the population or instead, let the wolf population be and risk having this species die off. The main reason behind keeping the wolves is the moose population. This population will sky rocket if the wolf population is not there due to the moose having no predators. If the moose population goes up then they will wreck havoc on the forest. Climate change has greatly impacted the living condition of both the wolves and the moose in the area and something needs to be done in order to keep this species alive.
