See biodiversity.

A method of controlling pests such as insects, mites, weeds and plant diseases using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs.

See also 'Biodiversity conservation'. Application of science to conservation problems addressing the biology of species, communities and the ecosystem that are perturbed either directly or indirectly by human or other agents. Its goal is to provide principles and tools for preserving biological diversity. The branch of biology that deals with threats to biodiversity and with preserving the biologic and genetic diversity of animals and plants.

The field of biogeochemistry deals with the effect of biological organisms on the chemistry of the Earth.

Biogeochemical cycles involve the fluxes of chemical elements among different parts of the Earth: from living to non-living, from atmosphere to land to sea, and from soils to plants.

Compounds that include organic atmospheric trace gases other than carbon dioxide and carbon monoxide; isoprenoids (isoprene and monoterpenes) are among the most prominent BVOC emitted (Kesselmeier & Staudt, 1999).

See 'Biofuel'.

A future greenhouse gas mitigation technology which produces negative carbon dioxide emissions by combining bioenergy (energy from biomass) use with geologic carbon capture and storage.

Land-based climate change mitigation strategy involving the planting of bioenergy crops or trees, which are burned in power stations or converted to biofuels, and the released CO2 being captured for long-term underground storage in geological reservoirs.
