The wildlife of Canada or biodiversity of Canada consist of over 80,000 classified species, [a] and an equal number thought yet to be recognized. [3] Known fauna and flora have been identified from five kingdoms: [ 4 ] protozoa represent approximately 1% of recorded species; chromist (approximately 4); fungis (approximately 16%); plants ...
The colonies of Prince Edward Island and British Columbia joined shortly after, and Canada acquired the vast expanse of the continent controlled by the Hudson's Bay Company, which was eventually divided into new territories and provinces. [3] Canada evolved into a fully sovereign state by 1982. [4]
Modern-day zoogeography also places a reliance on GIS to integrate a more precise understanding and predictive model of the past, current, and future population dynamics of animal species both on land and in the ocean. Through employment of GIS technology, linkages between abiotic factors of habitat such as topography, latitude, longitude ...
Beginning of animal evolution. [54] [55] 720–630 Ma Possible global glaciation [56] [57] which increased the atmospheric oxygen and decreased carbon dioxide, and was either caused by land plant evolution [58] or resulted in it. [59] Opinion is divided on whether it increased or decreased biodiversity or the rate of evolution. [60] [61] [62 ...
Most recent mammal species have a greatly varied evolutionary history: [41] Mammals that lived on the land masses of Northern Canada, able to survive in the polar deserts are the polar bear (Ursus maritimus), and the Arctic fox (Vulpes lagopus). Recent statistics show there are 26,000 polar bears worldwide, of which two of the three largest sub ...
The terrestrial ecoregions of Canada are all within the Nearctic realm, which includes most of North America. The Nearctic, together with Eurasia's Palearctic realm, constitutes the Holarctic realm of the Northern Hemisphere. [1] British Columbia is the most biodiverse province with 18 ecoregions across 4 biomes.
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time.Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area. [1]
This is a list of the mammal species recorded in Canada.There are approximately 200 mammal species in Canada. [1] Its large territorial size consist of fifteen terrestrial and five marine ecozones, ranging from oceanic coasts, to mountains to plains to urban housing, mean that Canada can harbour a great variety of species, including nearly half of the known cetaceans.
