  1. Biodiversity
    - The number and variety of life forms including species, found within a specific region as well as all the number and variety ecosystems within and beyond that region
  2. Protect
    - To guard legally from harm, a species that is listed as endangered, threatened, or of special concern
  3. Biodiversity hotspot
    - A place where there is an exceptionally large number of species in a relatively small area

    e.g Carolina Canada
  4. Community
    - All the populations of the different species that interact in a specific area or ecosystem

    e.g fish,coral, and sponges are a community
  5. Dominant species
    • - Species that are so abundant that they have the biggest biomass of any community member
    • - Are normally producers
  6. Keystone species
    • - A species that can greatly affect population numbers and the health of an ecosystem
    • - Generally not abundant
    • - Can be plants or animals
  7. Captive breeding
    -The breeding of rare or endangered wildlife in controlled settings to increase the population size

    e.g Black-footed ferret
  8. Ecosystem engineers
    - A species that causes such dramatic changes to landscapes that it creates a new ecosystem

    • e.g beavers

  9. Sucession
    -The series of changes in an ecosystem that occur over time, following a disturbance 

    e.g Beavers- forest to flooded forest to sunny pond to abandoned pond that becomes beaver meadow, wolf packs use beaver meadows
  10. Habitat loss
    - The destruction of habitats, which usually results from human activities 

    e.g forest destruction for living space
  11. Deforestation
    - The practice of clearing forests for logging or other human uses, and never replanting them
  12. Alien species
    - A species that is accidentally or deliberately introduced into a new location

    e.g Zebra mussels to Canada, Rabbits to Australia
  13. Invasive species
    - A species that can take over the habitat of native species

    • e.g Zebra mussels
    • Image Upload
  14. Overexploitation
    - The use or extraction of a resource until it is depleted

    Image Upload
  15. Extinction
    - The death of all the individuals of a species

    e.g Dinosaurs
  16. Biodiversity crisis
    - The current accelerated rate of extinctions
  17. Restoration ecology
    - The renewal of degraded or destroyed ecosystems through active human intervention
  18. Reforestation
    - The regrowth of a forest, either through natural processes or through the planting of seeds or trees in an area where a forest was cut down
  19. Biocontrol
    - The use of a species to control the population growth or spread of an undesirable species

    e.g Ladybugs for aphids
  20. Bioremediation
    - The use of living organisms to clean up contaminated areas naturally

    e.g Toxic metals, such as mercury (II), can be converted into nontoxic forms, such as mercury (0), by bacteria.
  21. Bioaugmentation
    - The use of organisms to add essential nutrients to depleted soils
