What is Holarctic?
[[File:Holartico.png|thumb|250px|Holarctic]] The '''Holarctic''' [[ecozone]] refers to the [[habitat]]s found throughout the northern [[continent]]s of the world as a whole. This region is divided into the [[Palearctic]] and the [[Nearctic]]. The palearctic is Northern Africa and all of Eurasia, with the exception of Southeast Asia and the Indian subcontinent. The [[Nearctic]] is [[North America]] north of southern [[Mexico]]. These are further subdivided into a variety of [[ecoregion]]s. Many [[ecosystem]]s, and the animal and plant communities that depend on them, are found across multiple continents in large portions of this [[ecozone]]. The continuity of these ecosystems results from the shared glacial history of this ecozone. Also, during glacial periods, [[mammal]] [[fauna]] was able to cross from [[Asia]] to [[North America]] via the [[Bering Strait]]. {{geo-stub}} [[Category:Ecozones]]
