  1. Biodiversity
    The number and variety of organisms found in a specific region

    eg. In our ecosystem the Biodiversity is very large
  2. Protect
    To legally guard from harm a species that is listed as endangered, threatened, or of special concern

    eg. Legally keeping a Tiger as a pet
  3. Biodiversity Hotspot
    A place where there is an exceptionally large number of species in a relatively small area

    eg. The Himalayas in India are a Biodiversity HotspotImage Upload
  4. Community
    All the populations of the different species that interact in a specific area or ecosystem

    eg. Our community is mostly filled with humans, however we have a lot of different species
  5. Dominant Species
    A species that is so abundant that it has the largest biomass of any community member

    eg. The highest food chain member is the most dominant
  6. Keystone Species
    A species that can greatly affect population numbers and the health of an ecosystem

    eg. Sea Otters are Keystone Species

  7. Captive Breeding
    The breeding of rare or endangered wildlife in controlled settings to increase the population size

    eg. Zoo's are Captive Breeding Centers
  8. Ecosystem Engineer
    A species that causes such dramatic changes to a landscape that it creates a new ecosystem

    eg. Beavers are Ecosystem Engineers
  9. Succession
    The series of changes in ecosystems that occurs over time following a disturbance

    eg. Lava is an example of Succession

  10. Habitat Loss
    The destruction of habitats, which usually results from human activities

    eg. When trees are cut down, all the species who lived in those trees are now suffering from Habitat Loss
  11. Deforestation
    The practice of clearing forests for logging or other human uses, and never replanting them

    eg. Wood cutters, cut trees and supply the timber to paper manufacturing companies to make paper, they never come back to replant them
  12. Alien Species
    A species that is accidentally or deliberately introduced to a new location, usually as a result of human activity

    eg. Zebra Mussels are Alien Species to some Aquatic Ecosystems, they are brought in by ships" Ballast water
  13. Invasive Species
    A species that can take over the habitat of native species or invade their bodies

    eg. A lot of Invasive species are fish and other organisms entering the ecosystems by Ballast waterImage Upload
  14. Overexploitation
    The use or extraction of a resource until it is depleted

    eg. Fishing is overexploitation because some fish become extinct due to being caught by fishers a lot
  15. Extinction
    The death of all of the individuals of a species

    eg. Dinosaurs are extinct
  16. Biodiversity Crisis
    The current accelerated rate of extinctions on earth

    eg. The current Biodiversity Crisis of the earth is pretty moderate
  17. Restoration Ecology
    The renewal of degraded or destroyed ecosystems through active human intervention

    eg. Recycling is an example of Restoration Ecology
  18. Reforestation
    The regrowth of a forest, either through planting of seeds or trees in an area where a forest was cut down

    eg. When environmental programs go to forests to plant trees
  19. Biocontrol
    The use of a species to control the population growth or spread of an undesirable species

    eg. Using lizards to eat unwanted bugs
  20. Bioremediation
    The use of living organisms to clean up contaminated areas naturally

    eg. growing certain plants in toxic areas, so they can clean up the soils by consuming the toxins
  21. Bioaugmentation
    The use of organisms to add essential nutrients to depleted soils

    eg. Planting clovers to replenish the nitrogen levels in soils
