What challenges does a snowshoe hare face in the tundra?

Snowshoe hares in the tundra face several challenges, including extreme cold temperatures and a limited food supply during winter months. Their white fur provides camouflage against snow but can make them vulnerable to predators when the snow melts. Additionally, climate change poses a threat by altering their habitat and food availability, as well as affecting the timing of seasonal changes that influence their survival strategies. Predation by species like lynx and foxes also remains a significant challenge.
