Abstract
Biomes are climatically and geographically defined as similar climatic conditions on the Earth, such as communities of plants, animals and soil organisms and are often referred to as ecosystems. Some parts of the earth have more or less the same kind of abiotic and biotic factors spread over a large area creating a typical ecosystem over that area. Such major ecosystems are termed as biomes. Biomes are defined by factors such as plant structures (such as trees, shrubs and grasses), leaf types (such as broadleaf and needleleaf), plant spacing (forest, woodland, savanna) and climate. Unlike ecozones, biomes are not defined by genetic, taxonomic, or historical similarities. Biomes are often identified with particular patterns of ecological succession and climax vegetation (quasi equilibrium state of the local ecosystem). An ecosystem has many biotopes and a biome is a major habitat type. A major habitat type, however, is a compromise, as it has an intrinsic inhomogeneity. The biodiversity characteristic of each biome, especially the diversity of fauna and subdominant plant forms, is a function of abiotic factors and the biomass productivity of the dominant vegetation. In terrestrial biomes, species diversity tends to correlate positively with net primary productivity, moisture availability and temperature. Ecoregions are grouped into both biomes and ecozones. A fundamental classification of biomes is: 1. Terrestrial (land) biomes - 2. Aquatic biomes (including Freshwater biomes and Marine biomes) Biomes are often known in English by local names. For example, a temperate grassland or shrubland biome is commonly known as steppe in central Asia, prairie in North America and pampas in South America. Tropical grasslands are known as savanna in Australia, whereas in Southern Africa it is known as veldt (from Afrikaans) nation's. Sometimes an entire biome may be targeted for protection, especially under an individual important climatic factors are Biodiversity Action Plan. Climate is a major factor determining the distribution of terrestrial biomes.
