Dolphin and Union Caribou, [1] Dolphin and Union caribou herd, [1] Dolphin-Union, locally known as Island Caribou, [2] are a migratory population of barren-ground caribou, Rangifer tarandus groenlandicus, that occupy Victoria Island in the Canadian Arctic Archipelago and the nearby mainland. They are endemic to Canada.
Michipicoten Island has plentiful wildlife (notably beaver, woodland caribou, and birds). It is located in the Great Lakes-St. Lawrence Forest region. [10] The island is made up of ancient lava bedrock related to volcanism of the Midcontinent Rift System [3] and is heavily forested, with over 20 inland lakes. It has a rugged interior ...
Caribou Island is an uninhabited island in the eastern end of Lake Superior, 40 kilometres (25 mi) south of Michipicoten Island. It lies entirely within the territorial waters of Canada although only about five kilometres from the international border between Canada and the United States .
The Peary caribou (Rangifer arcticus pearyi) is a subspecies of caribou found in the High Arctic islands of Nunavut and the Northwest Territories in Canada. They are the smallest of the North American caribou, with the females weighing an average of 60 kg (130 lb) and the males 110 kg (240 lb). [3]
The population of caribou within the reserve is one of the most threatened in Quebec, due to a variety of factors, such as its size, fragmentation, isolation and predation by the wolf. Although the reserve itself has an area of 434.19 km 2 (167.64 sq mi), the habitat used by the caribou extends to between 1,200 km 2 (460 sq mi) and 2,000 km 2 ...
The migratory woodland caribou refers to two herds of Rangifer tarandus (known as caribou in North America) that are included in the migratory woodland ecotype of the subspecies Rangifer tarandus caribou or woodland caribou [1] [2] that live in Nunavik, Quebec, and Labrador: the Leaf River caribou herd (LRCH) [3] [4] and the George River caribou herd (GRCH) south of Ungava Bay.

The mountain caribou diet consists of tree-dwelling lichens predominantly. They are unique in this aspect as in the far northern regions of their habitat zones ...
Barren-ground caribou have evolved to match their calving period with the period in which lichen has traditionally bloomed. [25] [23] [20] [24] The phenological process and timing between birthing and easily accessible lichen is critical to the survival rate of the subspecies. The trophic mismatch, due to abnormal temperature variations linked ...
