Chapter 56Terms and Ideas
Genetic diversity-genetic variation within a population and between populations
Species diversity-variety of species in an ecosystem
Ecosystem diversity-community interactions, extinction of one species has a negative impact on the species richness of the community
Habitat loss-single greatest threat to biodiversity
Introduced species-no natural predators so they outcompete native species
Overexploitation-human harvesting of wild organisms at rates exceeding the ability of populations to rebound
Extinction vortex Fragmentation and edges Movement corridor Protected areas Biodiversity hot spots Nature reserves Zoned reserves
Bioremediation Biological augmentation Restoration Sustainable development
