Chapter 51 Flashcards
Conservation Biology
application of biology to counter the loss of biodiversity
Restoration Ecology
To restore or recover different ecologies and environments
Genetic Diversity
sum total of all the different forms of genetic information carried by all organisms living on Earth today
Species Diversity
number of different species in the biosphere
Endangered Species
This is a species that is about to become extinct
Threatened Species
A species that is going to become endangered
Small population Approach
An approach to species conservation concerned with the factors that drive a small population to extinction, such as genetic drift, inbreeding, etc.
Extinction Vortex
A downward population spiral in which positive-feedback loops of inbreeding and genetic drift cause a small population to shrink, and unless reversed, become extinct.
Declining Population Approach
A proactive approach to species conservation that focuses on detecting, diagnosing and preventing population declines in order to keep the population above a minimum viable size.
Movement Corridor
a series of small clumps or a narrow strip of quality habitat (usable by organisms) that connects otherwise isolated patches of quality habitat
Zoned Reserve
area of land that is relatively undisturbed by humans and is surrounded by buffer zones that are minimally impacted by humans
Bioremediation
the act of treating waste or pollutants by the use of microorganisms (as bacteria) that can break down the undesirable substances
Biological Augmentation
uses organisms to add essential materials to a degraded ecosystem
Sustainable Development
Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
