In conservation biology, latent extinction risk is a measure of the potential for a species to become threatened. Latent risk can most easily be described as the difference, or discrepancy, between the current observed extinction risk of a species (typically as quantified by the (Red List )) and the theoretical extinction risk of a species predicted by its biological or life history characteristics.〔.〕 ==Calculation== Because latent risk is the discrepancy between current and predicted risks, estimates of both of these values are required (See population modeling and population dynamics). Once these values are known, the latent extinction risk can be calculated as ''Predicted Risk - Current Risk = Latent Extinction Risk.'' When the latent extinction risk is a positive value, it indicates that a species is currently less threatened than its biology would suggest it ought to be. For example, a species may have several of the characteristics often found in threatened species, such as large body size, small geographic distribution, or low reproductive rate, but still be rated as "least concern" in the IUCN Red List. This may be because it has not yet been exposed to serious threatening processes such as habitat degradation. Conversely, negative values of latent risk indicate that a species is already more threatened than its biology would indicate, probably because it inhabits a part of the world where it has been exposed to extreme endangering processes. Species with severely low negative values are usually listed as an endangered species and have associated recovery and conservation plans.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Latent extinction risk」の詳細全文を読む スポンサード リンク
