SNC1D Glossary terms 3

  1. Biodiversity
    The number and variety of organisms found in a specific region
  2. Protect
    To legally guard 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
  4. Community
    All the populations of the different species that live 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
  6. Keystone Species
    A species that can greatly affect population numbers and the health of an ecosystem but is not necessarily abundant e.g. Sea Otter
  7. Captive Breeding
    The breeding of rare or endangered wildlife in controlled settings to increase the population size
  8. Ecosystem Engineer
    A species that causes such  dramatic changes to landscapes that it creates a new ecosystem e.g. Human
  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
  11. Deforestation

  12. Alien Species
    A species that is accidentally or deliberately introduced to a new location, usually as a result from human activity
  13. Invasive Species
    A species that can take over the habitat of native species or can take over their bodies
  14. Overexploitation
    The use or extraction of a resource until it is depleted e.g. Fisherman often fish too many Atlantic Cod causing overexploitation
  15. Extinction
    The death of all the individuals of a species
  16. Biodiversity Crisis
    The current accelerated rates of extinction 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 of an undesirable species
  20. Bioremediation
    The use of living organisms to clean up contaminated areas naturally
  21. Bioaugmentation
    The use of living organisms to add essential nutrients to depleted soils
