Unusual
Number of Grizzly and Hybrid Bears Spotted in High Arctic
Two
Canadian biologists have reported sighting a handful of grizzly bears and
hybrid grizzly/polar bears at unusually high latitudes in the Arctic,
indicating that the interbreeding of the two bear species is becoming more
common as the climate warms and grizzlies venture farther north. The sightings
of three grizzly bears and two hybrid bears, made in late April and May,
represent an unprecedented cluster of these animals at such high latitudes. The
biologists even took DNA samples from a grizzly bear at 74 degrees North
latitude.
