  1. Chapter 55: Conservation Biology & Restoration Ecology • What is conservation biology? • The integration of all aspects of biology to conserve biological diversity at all levels • Ecology, physiology, molecular biology, genetics & evolutionary biology • What is restoration ecology? • Applies ecological principles to return humanly disturbed ecosystems back • to their natural state • What is biodiversity? • Biological diversity • 3 levels • Genetic diversity • Genetic variation within a population & genetic variation • between populations • Species diversity • The variety of species in an ecosystem or throughout the biosphere • Threatened species – species likely to be considered endangered • in the foreseeable future • Endangered species – species in danger of becoming extinct • within their range • Ecosystem diversity • The variety of biosphere’s ecosystems • Extinction of 1 species can impact its community & ecosystem

  2. Genetic diversity in a vole population Species diversity in a coastal redwood ecosystem Community and ecosystem diversity across the landscape of an entire region Figure 55.2 Three levels of biodiversity

  3. Chapter 55: Conservation Biology & Restoration Ecology • What is conservation biology? • What is restoration ecology? • What is biodiversity? • What things are threatening biodiversity? • Habitat loss • Introduced species • Overexploitation

  4. Figure 55.1 Tropical deforestation in West Kalimantan, Borneo Habitat loss

  7. Chapter 55: Conservation Biology & Restoration Ecology • What is conservation biology? • What is restoration ecology? • What is biodiversity? • What things are threatening biodiversity? • What’s the difference between fragmentation, an edge, and a corridor? • Fragmentation – division of natural habitat • Edge – boundary between ecosystems – species rich • Corridor – movement strip that connects habitats

  8. Figure 55.16 An artificial corridor
