Wolves have been present in Alaska for about
500,000 years and presently occur throughout most of mainland Alaska, on Unimak
Island in the Aleutians, and in most parts of southeastern Alaska. I remember
being Docked on the other side of Unimak Island and seeing a pack of wolves on
the hillside searching for food. Wolves
normally breed in February and March and litters averaging about five pups are
born in May or early June. Most female wolves first breed when 22 months old but
usually have fewer pups than do older females. Wolves have a high reproductive
rate. Nearly all of Alaska's wolf packs raise at least one litter of four to
seven pups successfully each year The
Alaska Department of Fish & Game periodically estimates wolf numbers, and in
1994-95 approximately 7,500 to 10,000 wolves in from 700 to 900 packs were
believed to be in the state. Population densities range from about one wolf per
25 to 75 square miles in southern and interior areas to one wolf per 150 square
miles in the coastal areas of northern and western Alaska. The
wolf was once a much maligned animal. In the western world, people feared and
hated wolves, and this legacy is reflected in stories such as
Little Red Riding Hood and
The Boy Who Cried Wolf. In these popular
children's tales the wolf is made out to be a marauder and a killer of livestock
and people.
There is some basis for The Boy Who Cried Wolf,
for wolves have killed cattle and sheep. But what of
Little Red Riding Hood? There are no
records of wolves killing humans in Canada or the United States. Yet, when
wolves were spotted near rural communities, fear used to grip the populace. Over
time this has become less prevalent. Today, many people know that scientists
studying wolves have lived very close to dens where there were pups without
being attacked. They have even taken pups from a den without being molested. The
parents have usually run away, returning later only to take their young to a
more private den or to a rendezvous site (a place where the pack meets).
In areas where wolves are hunted or trapped they fear people and are very wary.
However, in remote places, such as in the Canadian Arctic, they show little fear
and will often allow people to live near them "Oh, they look just
like dogs," is an appropriate comment often heard near wolf pens in a zoo, for
dogs are descendants of wolves.
It is virtually impossible to describe the typical appearance of wolves. Wolves
of many large arctic islands and Greenland usually appear snow-white from a
distance, but closer up often reveal gray, black, or reddish shades. Wolves of
northern North America and Eurasia vary in color. A single pack may contain
animals that are black, shades of gray-brown, and white. Wolves in the heavily
forested areas of eastern North America are more uniform in color. They are
often a grizzled gray-brown like some German shepherd dogs.
This colour variation is a good example of natural selection, which enables
those animals best suited to a particular environment to survive. On the arctic
islands, where much of the ground is snow-covered for at least nine months of
the year, being white is a distinct advantage, so wolves in the Arctic may be
nearly white. In the mottled grey, green, and brown world of the eastern forests
the normal coat of the wolf is an effective camouflage. As a wolf moves
stealthily, or rests, it blends into the background and is hardly seen.
Wolves in the Arctic have extremely dense underfur, which insulates them against
rigorous winters. Another adaptation to environment is their habit of hunting in
packs, or groups, which enables them to kill large animals -- deer, elk, moose,
caribou, bison, and muskox. |
