    Study Notes

    Conservation Biology

    • Conservation biology is an interdisciplinary field that aims to halt biodiversity loss, maintain ecosystem functions, and restore degraded ecosystems.
    • It was created in the mid-1980s by Michael Soule and other natural scientists.

    Biological Diversity

    • Biological diversity (biodiversity) refers to the variety of animals, plants, and microorganisms that exist on Earth.
    • It also includes the variation of ecosystems and genetic variations within and between species.

    Ecosystem Processes

    • Ecosystem processes maintain viable populations of plants, animals, and microorganisms.
    • Examples of ecosystem processes include nutrient cycling, soil respiration, pollination, fire disturbances, food web dynamics, and symbiotic relationships between species.

    Population Viability Analysis (PVA)

    • Conservation biologists conduct PVA to collect information on the level of extinction risk, causes of population decline, sources of future threats, and necessary management actions to reverse population decline.
    • PVA is often conducted in collaboration with natural science specialists.

    Focal Species

    • Conservation biologists use focal species to guide their protection of Earth's biodiversity.

    • There are six types of focal species:

      Keystone Species

      • An animal that plays a larger role in influencing the structure of its biological community.
      • Example: Grey Wolves.
      • Grey wolves prey on elk, ensuring only strong elk survive, and maintaining a balance in the ecosystem.

      Umbrella Species

      • A species with a wide ranging habitat, where conservation of its domain leads to the protection of many other species.
      • Example: Greater Sage-Grouse.
      • Conservation of the Greater Sage-Grouse's habitat leads to the protection of 82% more vertebrate species.

      Flagship Species

      • An animal that appeals to human emotions, making it a prime example of why to protect an ecosystem.
      • Example: Polar Bears.
      • Polar bears are used to influence the general populace to make moves towards protecting them and their habitat.

      Indicator Species

      • An animal whose presence level yields critical information about the biological community's environmental condition.
      • Example: Frogs.
      • Frogs are sensitive to ecological disturbances, and their population decline or alterations can indicate environmental problems.

      Economically Important Species

      • Plants and animals that are used by humans for food, medicine, tourism, pet trade, etc.
      • Example: Cinchona Tree.
      • The cinchona tree's bark produces quinine, used to treat malaria.

      Vulnerable Species

      • Plants and animals that lack adequate access to a specific resource(s).
      • Example: Giant Panda.
      • The giant panda is a vulnerable species that eats primarily bamboo, and its habitat is fragmented due to China's infrastructure development.

    Types of Conservation

    • Conservation biologists use two types of conservation:

      In Situ Conservation

      • Protecting species in their natural environment.
      • Includes habitat protection, restoration, and management, as well as population enhancement activities.
      • Examples: habitat protection, restoration, and management; creating corridors to facilitate wildlife movement.

      Ex Situ Conservation

      • Protecting species outside of their natural environment.
      • Includes captive breeding, colony relocation, and education.
      • Examples: zoos, aquariums, and botanical gardens; captive breeding and relocation programs.

    Sustainability

    • Sustainability is the outcome of successful biological conservation efforts.
    • It occurs when humans interact with a natural resource in a manner that lets the species reproduce in the wild, enhance its population's genetic diversity, and continue its ecological role within the ecosystem.
