Title: Chapter 55: Conservation Biology


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

Ecology
  • What is conservation biology?
  • What is restoration ecology?
  • What is biodiversity?
  • What things are threatening biodiversity?
  • Habitat loss
  • Introduced species
  • Overexploitation
  • Disruption of interaction networks (honeybee /
    pollination)

Chapter 55 Conservation Biology Restoration
Ecology
  • What is conservation biology?
  • What is restoration ecology?
  • What is biodiversity?
  • What things are threatening biodiversity?
  • Whats 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
