QUESTIONS LIST:

• critical load : amount of added nutrient, usually nitrogen or phosphorus, that can be absorbed by plants without damaging ecosystem integrity.
• extinction vortex : a downward population spiral in which inbreeding and genetic drift combine to cause a small population to shrink.
• biological magnification : organisms at high trophic levels experience higher concentrations of toxic compounds.
• conservation biology : integrating ecology, physiology, molecular biology, genetics, and evolutionary biology to conserve biological diversity at all levels.
• introduced species : species that humans move intentionally or accidentally from the species' native locations to new geographic regions.
• movement corridor : narrow strip or small clumps of habitat connecting otherwise isolated patches.
• greenhouse effect : warming of earth due to the atmospheric accumulation of carbon dioxide and certain other gases.
• hot spot : relatively small area with numerous endemic species.
• sustainable development : economic development that meets the needs of people today without limiting the ability of future generations to meet their needs.
• assisted migration : translocation of a species to a favorable habitat beyond its native range to protect the species from human-caused threats.
