Detailed explanation-1: -Factors that affect biodiversity in an ecosystem include area, climate, and diversity of niches.
Detailed explanation-2: -The size of a habitat is another factor in the great diversity of the rainforest. Area increases diversity because a larger plot is likely to have more habitats, hence niches, to support a greater variety of species. In addition, many species require a large range for adequate prey or seed forage.
Detailed explanation-3: -We found that patch size has a positive effect on phylogenetic diversity, presumably because environmental heterogeneity and niche opportunities are greater in bigger patches. Also, phylogenetic diversity was positively affected by edge density.
Detailed explanation-4: -As a general rule, increasing biodiversity can be achieved by diversifying the range of habitats or vegetation structures available at a site. This can be achieved by, for example, varying mowing regimes, planting or seeding with native tree and shrub species, or occasional soil disturbance.
