The decline of moose population followed sooner or later by a decline in the wolves population because the is less for the wolves.
The wolves and the moose on Isle Royale have a predator-prey relationship.
The wolf population declines following a decrease in the moose population primarily due to a reduction in available food sources. Moose are a key prey species for wolves, and when their numbers drop, wolves struggle to find enough sustenance to support their packs. This can lead to starvation, lower reproductive rates, and increased mortality among wolves, ultimately resulting in a decline in their population. Additionally, a smaller prey base can disrupt the social structure and dynamics within wolf packs, further exacerbating their decline.
It is difficult to provide an exact number, but it is estimated that there are around 200,000 to 500,000 arctic wolves left in the world. The population is considered stable overall, but threats such as habitat loss and climate change could impact their numbers in the future.
Declining wolf populations can lead to an increase in the moose population since wolves are their natural predator. This increase in moose numbers can then impact vegetation abundance and diversity, as moose overgrazing can cause shifts in plant communities and ecosystem dynamics. Maintaining a healthy wolf population is important for balancing the ecosystem and ensuring the sustainability of all species within it.

The wolves and the moose on Isle Royale have a predator-prey relationship.
The wolf population on Isle Royale in Lake Superior decreased significantly from 50 to only 14 individuals between 1975 and 1985. This decline was due to a combination of factors including genetic issues from a small population size, disease, and a lack of prey.
In the Great Lakes area, moose are often a large part of the diet of wolves. Therefore a decline in the wolf population would naturally follow the decline of the moose population on Isle Royale.
Ninety-nine percent of Isle Royale is designated as a federal wilderness area and as the island's top predator, wolves are essential to controlling the island's moose population.
A wolf pair arrived on the island in 1949.
If the number of wolves increased, then the population of caribou would decrease. Wolves are a predator of the caribou, so the population of the caribou would drop if more wolves were around.
The prey in the predator-prey relationship on Isle Royale are moose, which are herbivores that graze on vegetation. The predators are wolves, which hunt and feed on the moose population as their primary food source.
"Wolves: Behavior, Ecology, and Conservation" and "The Wolves of Isle Royale" are two non-fiction books about wolves by L. David Mech. Other books in that genre include: "Three Among Wolves: A Couple and Their Dog Live a Year with Wolves in the Wild" by Helen Thayer, "Of Wolves and Men" by Barry Lopez, "The Wolves of Yellowstone" by Michael K. Phillips.
There are gray wolves, red wolves, and white wolves(To my knowledge). There might be more colors though.
Other than those in Alaska: Yellowstone. Grand Teton. Isle Royale. Voyageurs. Glacier. Seeing wolves in the wild is a rare treat, usually possible only in Yellowstone in the winter.
There are about 150,000 wolves left in the world. They used to be at a large risk for extinction, but they are steadily increasing in population.
