Spinning Happiness

The mighty muskox (Ovibos moschatu) is a survivor from the ice age. Possessing powerful curved horns, which hang down like side bangs from a helmet-like skullcap, muskoxen are actually more closely related to sheep and goats than to cattle and oxen (although all of the above are members of the Bovidae family).

Adult muskoxen weigh from 180 to 400 kg (400 to 900 pounds) but they look much larger on account of their thick coats and large heads. Once muskoxen proliferated throughout the northern hemisphere alongside woolly mammoths, but hunting and habitat loss caused them to retreat further and further into the remotest parts of the north until the end of the nineteenth century when the animals could only be found in the unpopulated wilderness and empty islands of northern Canada and deep in the arctic vastness of Greenland. In these remote locations tiny herds of one to two dozen muskoxen still subsist on grasses, willows, lichens and moss while contending with terrible arctic predators and fearsome cold.

Fortunately the muskox is provisioned with fearsome horns and doughty neighbours to fend off polar bears and wolves. The herd is capable of assembling in a ring formation with horns outward to stand off wolves and ice bears (although such a strategy works less well against humans with our projectile weapons). To fight the cold, the muskoxen have fat reserves and one of the most remarkable insulating coats in the animal world.

A muskox’s coat is divided into two layers: a long stringy layer of coarse outer wool and an inner layer of soft warm undercoat called qiviut (this Inuit word now primarily denotes muskox wool but it was once also used to refer to similarly soft warm inner down of arctic birds). Qiviut is one of the world’s premier luxury fibres: it is allegedly 8 times more effective at insulation than sheep’s wool and yet is softer than cashmere.

The Musk Ox survived when the other greats of the Pleistocene – woolly mammoth, mastodon, sabertoothed cats, giant sloth – all went away. And it returned to Alaska by way of New York Harbour. Now, it turns out, the musk ox could again be the great survivor in our new Arctic age of extinction. Ross MacPhee, a curator in the department of mammalogy at the American Museum of Natural History in New York City, says the musk ox’s homogenous genetic makeup suggests it has been through population stress before and can survive boom-and-bust cycles.

“What we find with living musk oxen is they’re not exactly clones, but they’re so amazingly similar that there’s only one explanation,” MacPhee says. “And that explanation is that they had to have had a very severe pinch on their populations. We estimate that that happened about ten thousand years ago.” But that doesn’t mean it’s all good news for the cold-weather beast, which is most closely related to goats and sheep and can weigh up to 800 pounds. The pace of these changes could challenge even an animal as resilient as the musk ox, scientists say.

Brendan Kelly, an Arctic ecologist and research scientist for the National Oceanic and Atmospheric Administration, says all Arctic species are currently endangered by the rapid speed of climate change. “For organisms to adapt – whether it’s changing body size, or changing the timing that they have their calves, and hence can match when the plants are most nutritious – it really depends on the rate of the environmental change relative to the generation time of the organism,” Kelly says. “So if there’s a really, really rapid environmental change, it’s very hard for there to be an adaptive response.”

As I was reading about Musk Ox I found out that all of the muskox at the Myskoxcentrum in Härjedalen, Sweden, came from Ryøya, near Tromsø, Norway. What?!? Muskox on Ryøya? I knew about the Dovrefjell group and an attempt to introduce muskox on Svalbard, but I had never heard of a group in northern Norway. The search was on.

It turns out that there is a flock of more 40+ animals now running around free on a small island named Ryøya off the coast of Tromsø. NRK’s Ut i naturen television program made a 24-minute show about “Moskusøya” (“Muskox Island”) in 2006. Unfortunately the show is in Norwegian, but even if you don’t speak Norwegian, it’s still worth watching for a while if you want to see muskox running around and scientists trying to catch them. In the Ut i naturen program, we also get to see some historic television clips from the 1960s when the muskox first came to Troms.

In 1969, 25 muskox calves arrived in northern Norway via boat from Greenland. The idea was to raise muskox for their wool as domesticated livestock. The University of Fairbanks in Alaska had some kind of research project related to muskox husbandry (I haven’t looked into that yet) and the idea was transferred to Norway.

The undercoat wool of muskox, known as qiviut, is a highly valuable wool: it is warmer than wool, finer than cashmere and hypoallergenic. Sounds like the perfect winter clothing material, except that muskox are pretty rare and not widely domesticated – which makes it a very, very expensive material

In 1969, the herd was established at a farm in Bardu with the hope that eventually every farm in the area could have 2-3 muskox for a meaningful supplementary income. But by 1975, calls for the end of muskox experiment were being made. According to media reports, a hunter was killed by a muskox and the muskox population was being devastated by a virus (hmmm, sounds familiar, right?). So in 1976, the herd was moved to northern Troms, and five years later, the Tromsø University is taking care of them to preserve the species.

The Department of Arctic and Marine Biology took over the herd and moved them to Ryøya to study their behaviour and adaptation as arctic animals. Muskox as livestock in Norway didn’t work out, but who knows what the future holds. The Qiviut are still here.

While the scientists herd the muskox to collect measurements and/or for transportation to the overwintering station on the mainland, they quickly pull out the qiviut, which they sell to support their research. Qiviut is a bonus of having muskox in Norway — if you can catch them.

Well , don’t you worry I caught some of it for you to support the musk ox population growing not only on the American continent but also in other habitats that are good for them. This will enable the species to grow, get stronger, adapt and hey, probably outlive us all, since they already did that to the woolly mammoth.

Don’t worry, if I EVER find a woolly mammoth, I will share its’ wool with all of you …

As far as rare breeds are concerned and especially with the musk ox, they are being monitored by scientists to see what is happening with the herds and what their health is. A musk ox can be up to two metres long. The animal is characterised by a long and dense coat and wide hooves and drooping horns. Like domestic cows, musk oxen are ruminants, and allow their food to ferment in a separate stomach prior to digesting it. Musk ox are well protected against the cold Arctic winter. They have two layers of hair--a thick undercoat and heavy outer coat of long, dark hair. Musk ox are a key species in the Arctic, but populations are in decline. A new method is helping scientists to monitor these animals in often difficult to reach, remote locations.

A new method of hair analysis reveals what musk ox in the Arctic have been eating in recent years. The hair is sampled from the animals’ buttocks where it is longest and preserves a longer time series of the animals eating habits. Buttock hair also grows continuously throughout the year and so it gives the most representative picture of the animals’ yearly food intake. “Musk ox [are] a key species in the Arctic that we know surprisingly little about,” says lead author Jesper Bruun Mosbacher, a PhD student at the Arctic Research Centre, Aarhus University, Denmark. “We use a new method that has never been applied in this way before. And we can use it to monitor [musk ox] populations in locations where we otherwise wouldn’t visit very often,” says Mosbacher.

Musk ox are found throughout the Arctic, in Greenland, Canada, Alaska, Norway, and Russia. And some local populations are thriving. 

In west Greenland, populations have soared from just 27 in the early 1960s to around 25,000 estimated individuals today, says Mosbacher. But scientists still do not know where most musk ox are or how they are faring. "No one knows how many there are among the [unmanaged] population on the east coast [of Greenland]. The most recent estimate in 1990 was between 2,900 and 4,600 musk ox within the area of the Zackenberg research station," says Mosbacher.

“Understanding the connection between the environment and food is important, because then we can begin to understand what will happen as the climate changes." The muskox project is a collaboration between Arctic Research Centre in the Department of Bioscience, Aarhus University, the Copenhagen Zoo, the Department of Biology and Centre for Permafrost at the University of Copenhagen, and the Norwegian Institute for Nature Research.
