This opportunistic feeding behavior is a key survival strategy that ensures their continued presence in the demanding ecosystems of Alaska.
5. Reproduction And Life Cycle
The lifecycle of a wolverine is both fascinating and complex, beginning with mating in the late spring or early summer.
Females experience delayed implantation, where the fertilized egg remains dormant before implanting in the uterus later in the winter, ensuring births occur at a time when conditions are more favorable.
Typically, a female will give birth to two to three kits in a secluded den, often burrowed into the snow. These dens provide warmth and protection during the vulnerable early stages of life.
Wolverine mothers are incredibly protective and nurturing, investing considerable energy in raising their young.
The kits are weaned at around ten weeks but remain with the mother for over a year, learning essential skills for survival.
6. Elusive Nature And Challenges Of Study
