The only time at which the wolf migrates is during the wintertime when there is complete darkness for 24 hours. This makes Arctic wolf movement hard to research. About 2,250 km (1,400 mi) south of the High Arctic, a wolf movement study took place in the wintertime in complete darkness, when the temperature was as low as −53 °C (−63 °F).
The Arctic wolf spider can live for at least two years, grows as long as 1.6 inches (4 centimeters), and is a carnivore. [3]A 10-year study of the Arctic wolf spider revealed that the exoskeleton thickness averaged 0.104 inch (2.65 millimeters), a 2 percent increase over the 0.102 inch (2.6 millimeters) commonly found in the early years of the study, possibly the result of longer summers.
This wolf is native to the interior of Alaska, United States, and the Yukon, Canada save for the tundra region of the Arctic Coast. [4] Yukon wolves' main habitats are boreal forests, alpine, subalpine, and Arctic tundra. The population in Canadian Yukon is estimated to be 5,000, which ranges in all of Yukon except for Kluane National Park.
The gray wolf (C. lupus), the Ethiopian wolf (C. simensis), eastern wolf (C. lycaon), and the African golden wolf (C. lupaster) are four of the many Canis species referred to as "wolves". [37] Species that are too small to attract the word "wolf" are called coyotes in the Americas and jackals elsewhere. [ 38 ]
It is recognized as a subspecies of Canis lupus in the taxonomic authority Mammal Species of the World (2005). [4] It was formally discovered, classified, and named after Peter Bernard, sailing master of the gas schooner Mary Sachs of the Canadian Arctic Expedition and collected four other specimens of Canis Lupus Bernardi, and Joseph F. Bernard, his nephew, who made voyages into the Arctic as ...
Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest ) and tundra . [ 2 ]
Wolf howls can under certain conditions be heard over areas of up to 130 km 2 (50 sq mi). [15] Wolf howls are generally indistinguishable from those of large dogs. [16] Male wolves give voice through an octave, passing to a deep bass with a stress on "O", while females produce a modulated nasal baritone with stress on "U".
Illustration of a Pleistocene wolf cranium that was found in Kents Cavern, Torquay, England [1]. It is widely agreed that the evolutionary lineage of the grey wolf can be traced back 2 million years to the Early Pleistocene species Canis etruscus, and its successor the Middle Pleistocene Canis mosbachensis.
