Glossary Terms 1.3
Show Answers:

  1. Biodiversity
    • The number and variety of organisms found in specific regions.
    • Example: Pine trees, berry bushes, bunnies, deer, tigers, bears, sparrows, bacteria.
  2. Protect
    • To legally guard from harm  a species that is listed as endangered, threatened, or of special concern.
    • Example: Black rhino, cross river gorilla.
  3. Biodiversity Hotspot
    • A place where there is an exceptionally large number of species in a relatively small area.
    • Example: Amazon, coral reefs.
  4. Community
    All the populations of the different species that interact in a specific area or ecosystem.
  5. Dominant Species
    • A species that is so abundant that it has the biggest biomass of any community member.
    • Example: Humans, plants.
  6. Keystone Species
    • A species that can greatly affect population numbers and the health of an ecosystem.
    • Example: Kelp, sea otter.
  7. Captive breeding
    • The breeding of rare or endangered wildlife in controlled settings to increase the population size.
    • Example: Arabian Oryx
  8. Ecosystem Engineer
    • A species that causes such dramatic changes to landscapes that it creates a new ecosystem.
    • Example: Beavers, kelp
  9. Succession
    • The series of changes in ecosystems that occurs over time following a disturbance.
  10. Habitat Loss
    • The destruction of habitats, which usually results from human activities.
    • Example: Deforestation, dumping in bodies of water.
  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 to a new location, usually as a result of human activity.
    • Example:Rats, cane toads, cats.
  13. Invasive Species
    • A species that can take over the habitat of native species or invade their bodies.
    • Example: Zebra muscles, the black rat.
  14. Overexploitation
    • The use or extraction of a resource until it is depleted.
    • Example: Fish, forests.
  15. Extinction
    • The death of all of the individuals of a species.
    • Example: Dodo birds, mammoths.
  16. Biodiversity Crisis
    The current accelerated rate of extinctions on earth.
  17. Restoration Ecology
    The renewal of degraded or destroyed ecosystems through active human intervention.
  18. Reforestation
    • The regrowth of a forest, either 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.
    • Example: Cane toads, cats, monitor lizard.
  20. Bioremediation
    The use of living organisms to clean up contaminated areas naturally.
  21. Bioaugmentation
    • The use of organisms to add essential nutrients to depleted soils.
    • Example: Bacteria
