Transcript of Arctic Wolf
a. Kingdom: Animalia
b. Phylum: Chordate
c. Class: Mammal
d. Order: Carnivora
e. Family: Canidae
f. Genus: Canis
g. Species: Canis Lupus
What biome does the Arctic Wolf call home?
Tundra: extremely cold, icy, low biotic diversity, energy and nutrients in the form of dead organic material
Is the Arctic Wolf K-Selected or R-Selected?
: a species with a low intrinsic growth rate that causes the population to increase slowly until it reaches carrying capacity
: a species that has a high intrinsic growth rate, which often leads to population overshoots and die-offs
The Arctic Wolf is a K-selected species:
Long life span
Long time to reproductive maturity
Few numbers of reproductive events
Few numbers of offspring
Large size of offspring
Present parental care
Slow population growth rate
Density dependent population regulation
Stable population dynamics
Within that biome, what is the Arctic Wolf's specific habitat?
Canada, Alaksa, and the eastern and northern shores of Greenland
How is the Arctic Wolf's population organized?
They are scattered across a large area but live in packs of 7-10
With what organisms does the Arctic Wolf compete?
What organisms does the Arctic Wolf use for resources? How does it get food?
What organisms use the Arctic Wolf for resources? How does it avoid being hunted?
Does the Arctic Wolf have any symbiotic relationships?
Is the Arctic Wolf a keystone species?
They eat muskox, arctic hares, and caribou
The Arctic Wolf is a keystone species. Their gray wolf subspecies is a keystone species because once they kill animals they leave behind food for other animals after they are done eating. By doing this, the play a larger part in the ecosystem.
They compete with foxes for food
They compete with arctic foxes and polar bears for food
How is the Arctic Wolf uniquely adapted to its environment?
The Arctic Wolf has adapted to its environment by having two layers of fur. Their noses, ears, and legs are smaller than their subspecies the gray wolf in order to reduce heat loss. Their furry tail also keeps their nose warm.
The Arctic Wolf can live in complete darkness for up to 5 months
They are the only wolves left that are not on the endangered species list
Reach speeds of 40 mph while chasing prey.
Communicate through tale tale movements and growling.

Unlike other species of wolf, the Arctic wolf rarely comes into contact with human so does not face the threat of hunting or persecution. However, the greatest threat to the Arctic wolf is climate change. Extreme weather variations in recent years have made it difficult for populations of muskox and Arctic hares to find food, and this has caused a decline in numbers. In turn, this has reduced the traditional food supply of the Arctic wolf.
Industrial development also poses a threat to the wolf, as an increasing number of mines, roads and pipelines encroach on the wolf’s territory, and interrupt its food supply.
In tundra, parasites affects various mammalian species including reindeer, Arctic foxes, musk oxen, Arctic wolves, etc. Of the several parasites that affect these species, one of the most common is the tapeworm. In animals suffering from liver tapeworm cysts, tapeworms develop inside the body of the host organism and start feeding on food that the organism eats, thus leading to malnutrition and possibly death of the host.
