Threats to biodiversity have adverse effects on the ecosystem. Species diversity is the number of species and number of individuals of each species in a given area. Number of species increases with lake area, more time and more rapid evolution permits the evolution of more species, more species can tolerate the climatically favorable conditions in the tropics; conversely, fewer species can tolerate the climatically unfavorable conditions in temperate and polar regions, larger areas and physically or biologically complex habitats furnish more niches, species richness is limited by the partitioning of production or energy among species; therefore more productive habitats can support more species, competition affects niche partitioning and predation retards competitive exclusion, moderate disturbance retards competitive exclusion.
