Conservation Biology
Integrates ecology, physiology, molecular biology, genetics, and evolutionary biology to conserve biological diversity at all levels.
Endangered species
In danger of extinction throughout all or a significant portion of its range.
Threatened species
Those that are considered likely to become endangered in the near future.
Ecosystem services
Encompass all the processes through which natural ecosystems help sustain human life.
Introduced species
A non-native or exotic species.
Extinction vortex
A small population vulnerable to inbreeding and genetic drift.
Minimum viable population
The minimal population size at which a species is able to sustain numbers.
Biodiversity hot spot
A relatively small area with numerous endemic species and large number of endangered and threatened species.
Movement corridor
Narrow strips or series of small clumps of habitat connecting otherwise isolated patches.
Zoned reserve
An extensive region that includes relatively undisturbed by humans surrounded by areas that have been changed by human activity and are used for economic gain.
Critical Load
The amount that can be absorbed by plants without damaging ecosystem integrity.
Biological magnification
Biomass at any given tropic level is produced from a much larger biomass.
Assisted migration
The translocation of a species to a favorable habitat beyond it's native range to protect the species from human-caused threats.
Sustainable environment
Economic development that meets the needs of people today without limiting the ability of future generations to meet their needs.
