The Eurasian wolf (Canis lupus lupus), also known as the common wolf, [3] is a subspecies of grey wolf native to Europe and Asia. It was once widespread throughout Eurasia prior to the Middle Ages . Aside from an extensive paleontological record, Indo-European languages typically have several words for "wolf", thus attesting to the animal's ...
The wolf (Canis lupus; [b] pl.: wolves), also known as the grey wolf or gray wolf, is a canine native to Eurasia and North America. More than thirty subspecies of Canis lupus have been recognized, including the dog and dingo , though grey wolves, as popularly understood, only comprise naturally-occurring wild subspecies.
Gray wolf in YellowStone National Park. A clear example of humans ecosynthesiszing would be through the introduction of a species to cause a trophic cascade, which is the result of indirect effects between nonadjacent trophic levels in a food chain or food web, such as the top predator in a food chain and a plant. [4]
The gray wolf, after being extirpated in the 1920s and absent for 70 years, was reintroduced to the park in 1995 and 1996. Since then a three-tiered trophic cascade has been reestablished involving wolves, elk ( Cervus elaphus ), and woody browse species such as aspen ( Populus tremuloides ), cottonwoods ( Populus spp.), and willows ( Salix spp.).
Wolves have naturally migrated in the three state region. As of 2021, the estimated stable population is 4,400 in the three states. [20] Wolves may also disperse across the Great Plains into this region from the northern Rocky Mountain region which includes Wyoming with approximately 300 wolves and Colorado with a small population.
However, the divergence was a much greater 8.0% between gray wolf (C. lupus) mtDNA and eastern/red wolf haplotypes, and 10.0% between gray wolf and coyote haplotypes. The sequence difference observed between eastern Canadian wolf sequences and coyote sequences is consistent with a separation of 150 000 – 300 000 years, using a divergence rate ...
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 Alexander Archipelago wolf (Canis lupus ligoni), also known as the Islands wolf, [4] is a subspecies of the gray wolf.The coastal wolves of southeast Alaska inhabit the area that includes the Alexander Archipelago, its islands, and a narrow strip of rugged coastline that is biologically isolated from the rest of North America by the Coast Mountains.
