  1. a close relationship between two or more unrelated organisms:
    symbiosis (symbiotic relationship)
  2. when two organisms benefit from each other:
  3. when each species can only live in the presence of the other:
    obligative mutualism
  4. when each species benefits from the presence of the other, but can still survive without the other:
    facultative mutualism
  5. when one species lives in close association with another, and benefits; while the other does not gain benefit but is not harmed:
  6. when one species spends a significant portion of its life cycle in close association with another organism (host) and the host is negatively affected:
  7. when a female lays an egg into the nest of another individual:
    avian brood parasitism
  8. the resource and conditions present in an area that produce occupancy:
  9. the way an animal uses the physical and biological resources in a habitat:
    habitat use
  10. a series of innate and learned behavioral decisions made by an animal about what habitat it would use:
    habitat selection
  11. What can affect habitat selection:
    • angle of sun
    • species of vegetation
    • height, spacing, and density of vegetation
    • predator presence
    • competition
    • availability of lookouts
    • visibility
  12. a consequence of habitat selection, resulting in the disproportional use of some resources over others:
    habitat preference
  13. accessibility and attainability of physical and biological components of a habitat by animals:
    habitat availability
  14. the ability of the environment to provide conditions appropriate for individual and population persistence:
    habitat quality
  15. Habitat is:
  16. the unique combinations of vegetation existing in a specific area:
    plant communities
  17. What determines plant communities?
    • soil components/particles
    • temperature
    • elevation
    • solar radiation
    • slope
    • aspect
    • precipitation
  18. critters supported by the various combinations of plant communities:
    animal community
  19. area where two communities or successional stages overlap, creating a distinct community:
  20. the mixing of communities or successional stages:
  21. the progressive replacement of one dominant species or community by another in an ecosystem until a stable climax community is established:
  22. the entire sequence of ecological communities successively occupying an area from the initial stage to the climax community
    sere (seer)
  23. What are the seral stages?
    • primary succession
    • secondary succession
    • climax community
  24. What is a first order selection?
    physical or geographical range of a species
  25. What is a second order selection?
    home range of an individual or social group within that geographical range
  26. What is a third order selection?
    • related to species of how the components of the habitat within the home range are used
    • (foraging, bedding, breeding, parturition)
  27. What grasslands grow where?
    • shortgrass prairies grow to the west
    • mixed prairie grow in the middle
    • tallgrass prairies grow to the east
