Ecology of animal migration

Area of Science:

• Zoology
• Ecology
• Animal Behavior

Background:

• Many animal species exhibit migratory behaviors, traveling between distinct habitats for survival and reproduction.
• Migrations are crucial for numerous species, including marine mammals, sea turtles, fish, birds, insects, and terrestrial mammals.

Purpose of the Study:

• To provide an overview of the diverse and extensive migrations undertaken by various animal groups.
• To highlight the remarkable distances and strategies employed by animals during their annual or multi-year journeys.

Main Methods:

• Compilation and synthesis of existing data on animal migration distances and patterns.
• Categorization of migratory animals based on locomotion: swimming, flying, running, and walking.

Main Results:

• Whales undertake long annual migrations between warmer calving grounds and cooler feeding areas.
• Arctic terns and bar-tailed godwits exhibit exceptionally long annual and non-stop flights, respectively.
• Insects like monarch butterflies and globe skimmers undertake multi-generational migrations over thousands of kilometers.
• Terrestrial mammals like caribou, zebras, and wildebeest cover shorter distances compared to marine and avian migrants.

Conclusions:

• Animal migration is a widespread phenomenon involving incredible feats of endurance and navigation across various taxa.
• Migration strategies vary significantly, with flying and swimming animals often covering greater distances than terrestrial ones.
