Thus localities at lower latitudes have more species than localities at higher latitudes. Etymology[ edit ] The term biological diversity was used first by wildlife scientist and conservationist Raymond F.

Biologists most often define biodiversity as the "totality of genes, species and ecosystems of a region". Latitudinal gradients in species diversity Generally, there is an increase in biodiversity from the poles to the tropics.

However, tetrapod terrestrial vertebrates taxonomic and ecological diversity shows a very close correlation. Dasmann in the year lay book A Different Kind of Country [41] advocating conservation.

Provisioning services which involve the production of renewable resources e. Wilson used it as the title of the proceedings [44] of that forum. The similarity between the curves of biodiversity and human population probably comes from the fact that both are derived from the interference of the hyperbolic trend with cyclical and stochastic dynamics.


Some scientists believe that corrected for sampling artifacts, modern biodiversity may not be much different from biodiversity million years ago. Hotspots[ edit ] A biodiversity hotspot is a region with a high level of endemic species that have experienced great habitat loss. Among other factors, the diversity of all living things biota depends on temperature, precipitation, altitude, soilsgeography and the presence of other species.

Several ecological mechanisms may contribute to the gradient, but the ultimate factor behind many of them is the greater mean temperature at the equator compared to that of the poles.

Over the next million years or so, invertebrate diversity showed little overall trend and vertebrate diversity shows an overall exponential trend. It first appeared in a publication in when sociobiologist E. Hyperbolic model implies a second-order positive feedback. Gilbert White succinctly observed of his Selborne, Hampshire "all nature is so full, that that district produces the most variety which is the most examined.

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. This hypothesis considers temperaturemoistureand net primary production NPP as the main variables of an ecosystem niche and as the axis of the ecological hypervolume.

Selection bias amongst researchers may contribute to biased empirical research for modern estimates of biodiversity.Fukuoka | Japan Fukuoka | Japan.

Biodiversity is not evenly distributed, rather it varies greatly across the globe as well as within regions.

Among other factors, the diversity of all living things depends on temperature, precipitation, altitude, soils, geography and the presence of other study of the spatial distribution of organisms, species and ecosystems, is.
