AP Biology - Ch. 52-56

Integrates ecology, physiology, molecular biology, genetics, evolutionary biology to conserve biological diversity at all levels

Applies ecological principles to return ecosystems that have been disturbed by human activity to a condition as similar as possible to natural state

Genetic diversity, Species, diversity, Ecosystem diversity

Provides different crops, fibers, medicines,natural resources

Encompass all processes where natural ecosystems help sustain human life on Earth (ex: purify air/water)

-habitat loss-introduced species-overexploitation (overhunting)

Small population -- inbreeding/genetic drift -- loss of genetic variability -- reduction in individual fitness/adaptability -- lower reproduction -- higher mortality -- even smaller pop....

Minimal pop size at which a species can sustain its numbers and survive

Breeding-capable individuals of a pop

-small pop approach-declining pop approach

Determine what's making pop decline, help solve that in ecosystem

Where two ecosystems meet/blend together -- forms special ecosystems, very important to preserve

Areas where so many endangered species live in high concentration

-saved areas in a sea of habitat degraded by human activity-area that includes areas relatively undisturbed by humans surrounded by human populated areas

Use of organisms (fungi,plants,prokaryotes) to detoxify polluted ecosystems
