The entities of interest are usually individual plants or animals, and the measure of abundance can be, for example, number of individuals, biomass or coverage. 2. Ecological theory predicts that a complex community formed by a number of species is inherently unstable, guiding ecologists to identify what maintains species diversity in nature. Here, using a multispecies dynamical model of ecological communities including various interaction types (e.g. An area with four different ecosystems (say boreal, tundra, temperate grasslands, and temperate forests) has greater ecosystem diversity than the same size area with only two ecosystems (say temperate grasslands and forests). Ecosystems are most natural in wilderness areas. Cultured methanogens are Earlier studies often assumed a community with only one interaction type, either an antagonistic, competitive, or mutualistic interaction, leaving open the question of what the diversity of interaction types contributes … India is one of the 12 centres of diversity and origin of several cultivated plants in the world.

Ecological theory predicts that a complex community formed by a number of species is inherently unstable, guiding ecologists to identify what maintains species diversity in nature. Values of biodiversity can be categorized as follows: Biodiversity or biological diversity simply means the variety and variability among living organisms and the ecological complexes in which they occur. It means degree of change in species composition between sites or communities or along gradients. It is the variation of genes within the species. ... After several years, the forest showed diversity in tree species. Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity.
