An international team, including scientists from the University of Maryland, created a database called the Arctic Animal Movement Archive (AAMA) to study how animals behave in the Arctic and sub-Arctic regions. This archive includes information from over 8,000 animals in 201 tracking studies and involves contributions from more than 100 organizations in 17 countries.
The research found that caribou are giving birth earlier because of warmer temperatures, with differences shown in various groups of caribou. A study on golden eagles showed that young eagles are arriving in spring sooner after mild winters, which is affected by a climate pattern called the Pacific Decadal Oscillation.
Another study examined bears, caribou, moose, and wolves, showing how different animal species react to changing temperatures and snow conditions, which in turn affects the relationship between predators and their prey.
