Arctic Animals’ Movement Patterns are Shifting in Different Ways as the Climate Changes

11.20.2020
Seasonal cues, such as warmer spring temperatures or cooler temperatures in the fall, tell animals when to migrate, when to mate, and when and where to find food. Predators and prey, birds and mammals alike follow this natural schedule, and an overall shift of just a few days or weeks could have unknown impacts on these animals and ecosystems.
