SubarcticThe subarctic zone is a region in the Northern Hemisphere immediately south of the true Arctic, north of humid continental regions and covering much of Alaska, Canada, Iceland, the north of Scandinavia, Siberia, and the Cairngorms. Generally, subarctic regions fall between 50°N and 70°N latitude, depending on local climates. Precipitation is usually low, and vegetation is characteristic of the taiga. Daylight at these latitudes is quite extreme between summer and winter due to its high latitude.
InnuThe Innu / Ilnu ("man", "person") or Innut / Innuat / Ilnuatsh ("people"), formerly called Montagnais from the French colonial period (French for "mountain people", English pronunciation: ˌmɔːntənˈjeɪ), are the Indigenous inhabitants of territory in the northeastern portion of the present-day province of Labrador and some portions of Quebec. They refer to their traditional homeland as Nitassinan ("Our Land", ᓂᑕᔅᓯᓇᓐ) or Innu-assi ("Innu Land").
Holarctic realmThe Holarctic realm is a biogeographic realm that comprises the majority of habitats found throughout the continents in the Northern Hemisphere. It corresponds to the floristic Boreal Kingdom. It includes both the Nearctic zoogeographical region (which covers most of North America), and Alfred Wallace's Palearctic zoogeographical region (which covers North Africa, and all of Eurasia except for Southeast Asia, the Indian subcontinent, the southern Arabian Peninsula). These regions are further subdivided into a variety of ecoregions.
Mountain goatThe mountain goat (Oreamnos americanus), also known as the Rocky Mountain goat, is a cloven-footed mammal that is endemic to the remote and rugged mountainous areas of western North America. A subalpine to truly alpine species, it is a sure-footed climber commonly seen on sheer rock faces, near-vertical cliffs and icy passages. Mountain goats generally avoid venturing down into lower elevations—except during seasonal food shortages or during particularly bad weather—as the extreme elevation which they inhabit is their primary defense against predators such as black and brown bears, pumas and wolves.
Embryonic diapauseEmbryonic diapause ( delayed implantation in mammals) is a reproductive strategy used by a number of animal species across different biological classes. In most species, the process occurs at the blastocyst stage of embryonic development and is characterized by a dramatic reduction or complete cessation of mitotic activity, arresting most often in the G0 or G1 phase of division.
