biome

bi·ome

(bī′ōm′) A large community of plants and animals that occupies a distinct region defined by its climate and dominant vegetation. Grassland, tundra, desert, tropical rain forest, and deciduous and coniferous forests are all examples of biomes.

Translations

Biome

A major community of plants and animals having similar life forms or morphological features and existing under similar environmental conditions. The biome, which may be used at the scale of entire continents, is the largest useful biological community unit. In Europe the equivalent term for biome is major life zone, and throughout the world, if only plants are considered, the term used is formation. See Ecological communities

Each biome may contain several different types of ecosystems. For example, the grassland biome may contain the dense tallgrass prairie with deep, rich soil, while the desert grassland has a sparse plant canopy and a thin soil. However, both ecosystems have grasses as the predominant plant life form, grazers as the principal animals, and a climate with at least one dry season. Additionally, each biome may contain several successional stages. A forest successional sequence may include grass dominants at an early stage, but some forest animals may require the grass stage for their habitat, and all successional stages constitute the climax forest biome. See Desert, Ecological succession, Ecosystem, Grassland ecosystem

Distributions of animals are more difficult to map than those of plants. The life form of vegetation reflects major features of the climate and determines the structural nature of habitats for animals. Therefore, the life form of vegetation provides a sound basis for ecologically classifying biological communities. Terrestrial biomes are usually identified by the dominant plant component, such as the temperate deciduous forest. Marine biomes are mostly named for physical features, for example, for marine upwelling, and for relative locations, such as littoral. Many biome classifications have been proposed, but a typical one might include several terrestrial biomes such as desert, tundra, grassland, savanna, coniferous forest, deciduous forest, and tropical forest. Aquatic biome examples are fresh-water lotic (streams and rivers), fresh-water lentic (lakes and ponds), and marine littoral, neritic, upwelling, coral reef, and pelagic.

Biome

An entire community of living organisms in a single major ecological area.

Biome

an aggregation of plant and animal species that make up the living population of a particular region. The term is used mainly in foreign ecological and biogeographic literature. The term “biota,” which is applied to wider areas of the earth’s surface, expresses a similar idea.

biome

[′bī‚ōm] (ecology) A complex biotic community covering a large geographic area and characterized by the distinctive life-forms of important climax species.

biome

[bi´ōm] a large, distinct, easily differentiated community of organisms arising as a result of complex interactions of climatic factors, flora, fauna, and substrate; usually designated according to kind of vegetation present, such as tundra, coniferous forest, deciduous forest, or grassland.

bi·ome

(bī'ōm), The total complex of biotic communities occupying and characterizing a particular geographic area or zone. [bio- + -ome]

biome

(bī′ōm′)n. A major regional or global biotic community, such as a grassland or desert, characterized chiefly by the dominant forms of plant life and the prevailing climate.

biome

An ecosystem with a distinct climate, organisms and substrates, all of which interact to produce a distinct and complex biotic community.

bi·ome

(bī'ōm) The total complex of biotic communities occupying and characterizing a particular geographic area or zone.

biome

a major regional ecological community of organisms usually defined by the botanical habitat in which they occur and determined by the interaction of the substrate, climate, fauna and flora. The term is often limited to denote terrestrial habitats, e.g. tundra, coniferous forest, grassland. Oceans may be considered as a single biome (the marine biome), though sometimes this is subdivided, e.g. coral reef biome. There is no sharp distinction between adjacent biomes.
