A biome (/ ˈ b aɪ. oʊ m /) is a distinct geographical region with specific climate, vegetation, and animal life. It consists of a biological community that has formed in response to its physical environment and regional climate . [ 1 ]
The WWF ecoregions are classified by biome type (tropical and subtropical moist broadleaf forests, temperate grasslands, savannas, and shrublands, tundra, etc.), and into one of eight terrestrial realms. Australia, together with New Zealand, New Guinea and neighboring island groups, is part of the Australasian realm. The IBRA bioregions ...
Earth's biosphere is divided into several biomes, inhabited by fairly similar flora and fauna. On land, biomes are separated primarily by latitude. Terrestrial biomes lying within the Arctic and Antarctic Circles are relatively barren of plant and animal life. In contrast, most of the more populous biomes lie near the equator.
A pine forest is an example of a temperate coniferous forest Forest communities dominated by huge trees (e.g., giant sequoia, Sequoiadendron gigantea ; redwood, Sequoia sempervirens ), unusual ecological phenomena, occur in western North America, southwestern South America, as well as in the Australasian region in such areas as southeastern ...
Similarly, another author indicated that there are 14 distinct biomes, including forests, grasslands, and deserts, among the 846 ecoregions that make up the area. Ecoregions vary in size; the island group of St. Peter and St. Paul Rocks in the Atlantic Ocean is only 6 km2, while the East Siberian Taiga is 39 million km2.
They also fall under ten biomes: Deserts and Xeric Shrublands, Flooded Grasslands and Savannas, Mangroves, Montane Grasslands and Shrublands, Temperate Broadleaf and Mixed Forests, Temperate Conifer Forests, Tropical and Subtropical Coniferous Forests, Tropical and Subtropical Dry Broadleaf Forests, Tropical and Subtropical Grasslands, Savannas ...
In physical geography, tundra (/ ˈ t ʌ n d r ə, ˈ t ʊ n-/) is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: Arctic, [2] Alpine, [2] and Antarctic.
Generally speaking, animal communities are reliant on specific types of plant communities. [7] Some plants and animals have habitat requirements which are met in a wide range of locations. The small white butterfly Pieris rapae for example is found on all the continents of the world apart from Antarctica.
