Presentation Transcript

  1. Conservation Biology and Restoration Ecology Chapter 56 Terms and Ideas

  2. Three Levels of Biodiversity • 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

  3. Threats to Biodiversity • 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

  4. Conservation • Extinction vortex • Fragmentation and edges • Movement corridor • Protected areas • Biodiversity hot spots • Nature reserves • Zoned reserves

  5. Restoration Ecology • Bioremediation • Biological augmentation • Restoration • Sustainable development
