Nearctic biogeographical realm comprises North America and Greenland. It is also commonly known as New World ecoregion. Nearctic poses various terrestrial and freshwater ecosystems and it is particularly renowned for its vast contiguous track of temperate coniferous and broadleaf forests of United States and Canada. Historically speaking, nearctic was joined with palearctic 180 million years ago and collectively both palearctic and nearctic was part of Laurasia which is one of the supercontinents after the split of Pangaea- the mega-supercontinent that split 180 million years ago. The other super-continent was Gondwanaland that comprised south America, Africa and part of Asia.
Majority of our nearctic members are either from United States or from Canada and their roles in Species Ecology is manifold due to broad representation of ecologically unique biomes that nearctic holds. Some of our nearctic members are honorary executives due to their ground breaking contribution relating to conservation biology in general and socio-ecological science in particular.
