Across
  1. 2. Endangered species of burrowing vertebrate found in the North American desert
  2. 6. Individuals arranged in space following a pattern where they are equally spaced apart from one another
  3. 9. Competition between individuals of the same species
  4. 11. J-shaped growth curve, where the RATE of growth (slope) increases as population size increases
  5. 12. Measure of offspring an individual or a population is able to produce over a given time period
  6. 14. Graph describing the survival of a group of individuals in a population from birth to death of the last member in the group
  7. 15. Communal courtship area males use to attract and mate with females
  8. 16. Individuals arranged in space following a pattern where they aggregate in certain areas
  9. 18. Set of populations linked by dispersal or movement of individuals among them
  10. 20. Group of individuals of the same age
  11. 21. Total range of environmental conditions under which a species could survive and reproduce (hint: type of niche)
  12. 22. Type of sampling design where survey points are randomly located within predefined areas [to look at population estimates]
  13. 23. Form of mimicry where one palatable species mimics an unpalatable one
  14. 25. Movement out of an area or population
  15. 27. Type of sampling design where surveyed points are laid out in a grid [to look at population estimates]
Down
  1. 1. S-shaped growth curve, where the RATE of growth (slope) decreases once population size increases beyond K/2
  2. 3. Relative number of males to females in a population
  3. 4. Interaction between 2 species where one benefits while the other is harmed, but not killed directly
  4. 5. Age-specific statistical summary of a population's survival patterns
  5. 7. Competition between individuals of different species
  6. 8. Relative measure of a population size or density
  7. 10. The number of individuals in a population the environmental resources of a given area can support
  8. 13. Individual produced via sexual reproduction (arising from a single fertilized egg)
  9. 17. Form of plant chemical defense which is abundant in the plant & reduces nutritional quality or palatability
  10. 18. Measure of individual deaths in a population over a given time period
  11. 19. Individual produced asexually (clonally)
  12. 24. Number of individuals in a population per unit area
  13. 26. Actual range of environmental conditions that a species exploits based on interspecific interactions (hint: type of niche)
