|
Nonnative species that migrate or are introduced by humans into a new ecosystem; also called exotics.
|
alien species
|
|
|
Total number of species, the variability of their genes, and the communities in which they live.
|
biodiversity
|
|
|
Regions of the world that contain unusually large concentrations of species.
|
biodiversity hotspots
|
|
|
Computer technologies used to study the genome.
|
bioinformatics
|
|
|
Scientific discipline that seeks to understand the effects of human activities on species, communities, and ecosystems and to develop practical approaches to preventing the extinction of species and the destruction of ecosystems.
|
conservaiton biology
|
|
|
Phenomenon in which the edges around a landscape patch provide a slightly different habitat than the favorable habitat in the interior of the patch.
|
edge effect
|
|
|
A species that is in peril of immediate extinction throughout all or most of its range (e.g., California condor, snow leopard).
|
endangered species
|
|
|
Species that evoke a strong emotional response in humans; charismatic, cute, regal (e.g., lions, tigers, dolphin, panda).
|
flagship species
|
|
|
Use of computers to discover places where biodiversity is high outside of preserved areas.
|
gap analysis
|
|
|
Predicted increase in the Earth's temperature due to human activities that promote the greenhouse effect.
|
global warming
|
|
|
Species whose activities significantly affect community structure.
|
keystone species
|
|
|
A number of interacting ecosystems.
|
landscape
|
|
|
Population subdivided into several small and isolated populations due to habitat fragmentation.
|
metapopulation
|
|
|
When the number of individuals taken from a population is so great that the population becomes severely reduced in numbers.
|
overexploitation
|
|
|
Any environmental change that adversely affects the lives and health of living things.
|
pollution
|
|
|
Calculation of the minimum population size needed to prvent extinction.
|
population viability analysis
|
|
|
Subdiscipline of conservation biology that seeks ways to return ecosystems to their former state.
|
restoration ecology
|
|
|
Population that is found in an unfavorable area where at best the birthrate equals the death rate; sink populations receive new members from source populations.
|
sink population
|
|
|
Population that can provide members to other populations of the species because it lives in a favorable area, and the birthrate is most likely higher than the death rate.
|
source population
|
|
|
Management of an ecosystem so that it maintains itself while providing services to human beings.
|
sustainable development
|
|
|
Species that is likely to become an endangered species in the foreseeable future (e.g., bald eagle, gray wolf, Louisiana black bear).
|
threatened species
|
