Since the Mayan apocalypse is due to hit on Thursday (or is it Friday?), I figure I should get at least one more post out before we are all (possibly) wiped out. Just in case we aren’t, and you are interested in volunteering on a post-apocalypse wolverine project, the Friends of Scotchman Peaks Wilderness in Idaho are looking for people to help them run live traps and cameras this winter. Information can be found here.
The first recorded case of rabies in a wolverine has been documented in Alaska, and an article on the Alaska Fish and Game website provides a thorough explanation of the circumstances. The female wolverine was carrying a strain of Arctic fox rabies and apparently fought with and infected a wolf shortly before she died (she also had a goose egg in her stomach, proving once again that wolverines are indeed versatile in their eating habits.) The incident is notable because it represents a first instance of recorded infection in a species, but the article is worth reading for its deeper exploration of rabies epidemiology in Alaskan fox species, the relationship between rabies outbreaks and ecological processes, and the possible connection between climate change, displacement of Arctic foxes by red foxes, and a potential related change in rabies prevalence.
Several interesting reports and papers have come out over the past few weeks – the 2012 report for the North Cascades Project was released, as well as the most recent update to the Idaho Recreation study. Both are available at the Wolverine Foundation website. And a new paper from Sweden looks at habitat selection in areas where lynx and wolverine overlap. I have not yet had a chance to read through all of these in detail but will report back once I do – provided, of course, that we have not met with fiery doom in the meantime.
