Biodiversity is that the variety and variability of life on Earth. Biodiversity is usually a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is typically greater near the equator, which is that the results of the nice and cozy climate and high primary productivity. Biodiversity isn't distributed evenly on Earth, and is richest within the tropics. Marine biodiversity is typically highest along coasts within the Western Pacific, where sea surface temperature is highest, and within the mid-latitudinal band altogether oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but are going to be likely to slow within the future. Ecosystem services are the suite of advantages that ecosystems provide to humanity. The natural species, or biota, are the caretakers of all ecosystems. It is as if the natural world is an enormous bank account of capital assets capable of paying life sustaining dividends indefinitely, but only if the capital is maintained. Biodiversity's relevance to human health is becoming a world political issue, as scientific evidence builds on the worldwide health implications of biodiversity loss. The top journals are peer reviewed scholarly journals. These provide high quality, meticulously reviewed and rapid publication, to cater the insistent need of scientific community.
