It’s mid-March, the grizzlies are up and about, and wolverine research season is drawing to a close. Wolverine kits all over the Rockies (and presumably the world) are marking their one-month birthdays, and wolverine researchers are gearing up for the tasks that can be accomplished during the snow-free months – investigating GPS collar food sites and exploring possible den locations, trekking back to Mongolia to interview herders and explore summer snow-patch methods for finding tracks, writing up the winter’s results, and, of course, preparing for next season’s work.
Among the interesting projects in store this summer, Evergreen College student Dallas LaDucer is preparing for a Wolverine World Tour to study the interactions of captive wolverines in zoos around the world. As a researcher and as a writer, the wolverine fixation can be challenging, because we have very few opportunities to interact face-to-face with wolverines. The animal’s elusiveness is part of its mystique, but it also leaves us with big gaps in both scientific understanding and compelling narrative about individual animals. Dallas, on the other hand, is one of the fortunate people who get to spend a lot of time with actual wolverines. From raising a captive female kit, to working as a zookeeper, to his current senior project investigating the interactions of wolverines to better understand their body language and social life, he’s spent a lot of time with gulos, and has observed that interactions vary according to the individual personalities of the animals, as opposed to strict gender or age hierarchies. He has looked at only a very small sample, however, because so few zoos in North America have more than one captive wolverine. His senior project will take him to Europe to watch wolverines in zoos in Russia, Finland, and Sweden. The major application of the work may be to help zookeepers better understand how to care for captive animals, but more knowledge about wolverine sociability could also inform conservation efforts. And, from an authorial perspective, I simply want to know more about what makes individual wolverines tick, because that information helps make good stories. So there are a lot of reasons to be interested in this project, and I am eager to hear how things go. Dallas is fundraising for the project here, so if anyone is interested in contributing, check it out.
A few other news items of interest have, as usual, slipped by me in the rush of activity that comes with spring. Skiers at Whitefish outside of Glacier National Park, Montana, should keep their eyes open for a wolverine that was spotted there earlier this week. Keep a camera handy too and maybe someone will be lucky enough to get a photo of a wild wolverine. Meanwhile, in Glacier National Park, British Columbia, Canada (not to be confused with the previously mentioned Glacier National Park, Montana) a wolverine photographed and videoed itself playing with a rope or cable that was part of a camera-trapping effort. It’s a brief glimpse of the wolverine’s playful side, although one of the scientists involved with the Trans-Canada Highway study, of which this particular camera-trap was a part, apparently takes issue with the notion of anthropomorphizing wolverines to the point of admitting that they play. In an article on the project in the Revelstoke Times Review, scientist Kelsey Furk states that she thinks that the rope was just smelly and therefore drew the wolverine’s attention, although no one seems to object to the repeated reference to the wolverine “dancing” with the rope. Play behavior has been demonstrated in many mammal species and I’m pretty convinced that wolverines not only enjoy messing around with stuff for the sake of messing around with it, but that they also have a particular mustelid sense of humor. I’m spending enough time playing with a 20-month-old human boy these days to understand that flinging a smelly rope around in the snow is no less intellectually edifying (and, in fact, is perhaps more so) than repeatedly plugging in and unplugging various electronics. Bottom line: if the kid’s behavior counts as play, so does the wolverine’s.
On a more serious note, the article about the Trans-Canada Highway project highlights an important study that will help us better understand the effects of transportation corridors on wolverines. The journalist repeats a few things as fact, however, that are actually still speculative. The most important is the idea that wolverines are disturbed by recreation. There are limited anecdotal suggestions that this might be true, but there’s also an intimation from on-going research that it might not be true. We still don’t know.Until we do, we need to be careful about the claims that we make.
