2 key strategies in restoration ecology

Back 31

Bioremediation
Biological Augmentation

Back 36

IUCN red list

human        kind  

Front 38

___%of all species that have occurred on the earth
are Extinct

In conservation biology is trying to conserve ________

Back 43

focuses on population size, genetic diversity, and critical habitat
are going to come in contact with one or two of the biotic factors in a population

Front 58

positive feedback system

Back 58

extinction vortex

Front 59

Some level population size that if it get below
it. the species is doomed. This is due to                                        inbreeding
and other population effects

Back 59

MVP

Front 60

calculate MVp we must look at the

Effecive population size

Front 62

causes isolation- genetic diversity is low

Back 62

Look at the geographic range where the most
endangered species live

Back 63

biodiversity hot spot

attempts to
restore degraded ecosystems and returning it to a native state


                    Have to restore has to
convert the species to its natural area

Back 64

restoration Ecology

Front 65

Bio remediation

Back 65

using organisms to detoxify and area-taking bacteria that can take a toxin and convert it back into something useable in and environment

Back 66

uses
organism to add things back into our system


                    ex.
