Summary:
- Researchers have found that caribou migration patterns in North America are shrinking due to climate change and human activity.
- The study analyzed data from over 50 years and found that caribou are now traveling shorter distances and spending less time in their traditional migration routes.
- This decline in migration patterns is concerning as it can impact the overall health and survival of caribou populations, which are an important part of the ecosystem and a vital food source for Indigenous communities.
