Wolves Wolves are adapted to Isle Royale well. Some strategies they've adapted are hunting and eating in packs. They also live in packs for a higher chance of survival. They are also one of the top predators on the island, so they have that advantage.
Moose Unfortunately, moose have a hard time adapting to the winters on Isle Royale. They die due to cold temperatures. Ticks also cause them to lose fur, so it's easier for them to decease.
Balsam Fir Fir trees have adapted well. They don't need as much energy as other trees since their leaves are small. They also have an advantage in the winter. They're small, spiky, cone-shaped leaves are what helps them survive. The leaves are strong and small, so they survive heavy snowfalls.
Ticks The existence of the moose tick(Dermacentor albipictus) depends entirely on the existence of the moose population. It feeds of the blood of only the moose on Isle Royale. They've adapted to living off the moose on the island. They cause moose to lose their hair, which makes them subjected to die easily from the extreme cold temperatures in the winter. When ticks lay eggs, they lay them in soil and on fir trees. The moose also use the fir trees as a source of food.
