Scientists resurrect 700-year-old viruses

(Phys.org) —Eric Delwart of the Blood Systems Research Institute in San Francisco and colleagues have found two 700-year-old viral sequences in frozen caribou dung in an arctic ice patch. The researchers isolated part of ...

Clues to Neanderthal hunting tactics hidden in reindeer teeth

Scientists have found that our cousins the Neanderthal employed sophisticated hunting strategies similar to the tactics used much later by modern humans. The new findings come from the analysis of subtle chemical variations ...

Caribou drone study finds 'enormous variation' within herd

Herd animals may not be as conformist as we thought, according to new research published in Philosophical Transactions of the Royal Society B. The first paper to use drones to record the movement of individual animals within ...

Climate change will endanger caribou habitat, study says

Reindeer, from Northern Europe or Asia, are often thought of as a domesticated animal, one that may pull Santa's sled. Caribou, similar in appearance but living in the wilderness of North America, are thought of as conducting ...

Caribou may be indirectly affected by sea-ice loss in the Arctic

Melting sea ice in the Arctic may be leading, indirectly, to fewer caribou calf births and higher calf mortality in Greenland, according to scientists at Penn State University. Eric Post, a Penn State University professor ...

Arctic sea-ice loss has widespread effects on wildlife

With sea ice at its lowest point in 1,500 years, how might ecological communities in the Arctic be affected by its continued and even accelerated melting over the next decades? In a review article in the journal Science, ...

Mountain caribou's ancient ancestry revealed

The declining mountain caribou populations of Canada's southern Rockies are a more distinct breed than scientists previously believed, according to a new study by University of Calgary researchers that is shedding light on ...

Reindeer

many, see text

The reindeer (Rangifer tarandus), also known as the caribou in North America, is a deer from the Arctic and Subarctic, including both resident and migratory populations. While overall widespread and numerous, some of its subspecies are rare and one (or two, depending on taxonomy) has already gone extinct.

Reindeer vary considerably in color and size. Both sexes grow antlers, though they are typically larger in males. There are a few populations where females lack antlers completely.

Wild reindeer hunting and herding of semi-domesticated reindeer (for meat, hides, antlers, milk and transportation) is important to several Arctic and Subarctic people. Even far outside its range, the reindeer is well known due to the myth, probably originating in early 19th century America, in which Santa Claus's sleigh is pulled by flying reindeer, a popular secular element of Christmas. In Lapland, reindeer pull pulks.
