Knowra Caribou Caribou Caribou are North American populations of Rangifer tarandus, a deer species whose males and females both grow antlers. Wild caribou include migratory tundra herds and woodland populations.
Rangifer tarandus : A circumpolar deer species known as caribou in North America and reindeer in Eurasia. Caribou are the North American populations of this species.
Caribou foraging : The seasonal selection and consumption of plants, lichens, and other foods by caribou. Shifting diets let caribou use changing tundra and boreal resources.
Caribou hunting : The harvesting of caribou for food and other uses by Indigenous communities and other hunters. Hunting is a source of food and a central management concern.
Caribou population cycles : Long-term rises and declines in the abundance of caribou populations. Population fluctuations affect predator food supplies, harvests, and conservation priorities.
Reindeer : The Eurasian name for Rangifer tarandus, including domesticated and wild populations. The same species is called reindeer across Eurasia, though usage and management differ.
Caribou migration : Seasonal movement by caribou between ranges used for calving, summer feeding, and winter survival. Long-distance migrations define many tundra populations and their annual life cycle.
Caribou locomotion : The ways caribou travel across land and water, including adaptations for snow and long-distance movement. Broad hooves and efficient travel help them cross snow, wetlands, and rivers.
Caribou conservation : Efforts to maintain caribou populations, habitats, and ecological relationships. Many populations face pressures that require coordinated habitat and harvest decisions.
Predator–prey dynamics : The reciprocal effects of predators and prey on one another's populations and behavior. Caribou abundance can alter wolf populations and predator pressure.
Moose : The largest living deer species, native to northern forests of Eurasia and North America. Moose share northern habitats with caribou but differ in size, diet, and social behavior.
