Across
  1. 3. formal system of naming species of living things by giving each a name composed of two parts
  2. 6. a measure of diversity that accounts for species richness and evenness. The closer to 1 the more diverse an area is.
  3. 8. the natural environment in which an animal or plant usually lives
  4. 9. a measure of diversity also known as relative species abundance
  5. 12. organisms classified as this have a large number of offspring and low parental care
  6. 13. species definition that defines a species as a group of organisms that can interbreed to produce fertile offspring
  7. 14. sampling technique that measure abundance and distribution
  8. 15. classification system that requires abiotic data including PE ratio and annual precipitation
  9. 17. sampling technique that only measures abundance
  10. 20. relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species
  11. 22. an interacting group of various species in a common location
  12. 23. a group of organisms that consists of a common ancestor and all of its descendants
  13. 27. species definition that defines a species as groups of organisms that share a pattern of ancestry and descent and which form a single branch on the tree of life
  14. 28. the number of individuals present
  15. 29. another assumption of cladistics
  16. 31. a nest in a tree is an example of this species interaction
  17. 33. a measure of diversity that uses quadrats and would be good for grass
  18. 34. Linnaeus used differences and similarities in these to determine his classification system
  19. 35. largest taxon in Linnaeus' original classification system
  20. 36. type of species interaction where one party benefits and the other is not impacts
Down
  1. 1. a measure of diversity calculated by counting the total number of different species present
  2. 2. branching point in a cladogram
  3. 4. bees and flowers area an example of this species interaction
  4. 5. smallest taxon in the Linnaean system
  5. 7. a way to reduce bias
  6. 10. species definition that relies on morphological data and emphasizes groups of physical traits that are unique to each species
  7. 11. type of species interaction where the host is harmed and the parasite benefits
  8. 16. a measure of diversity calculated by the formula: number of quadrats where species is present / total number of quadrats
  9. 18. a mule is one of these
  10. 19. classification system that requires the height and the percentage cover only of the tallest plant layer
  11. 21. assumption of cladistics
  12. 24. how individuals within a population are spaced within their region
  13. 25. sampling technique that should be use if multiple types of environments are present in the sampling area
  14. 26. type of species interaction characterised by long term, close relationship and must be between individuals of different species
  15. 30. type of species interaction where one animals eats the other
  16. 32. method of reproduction only requiring one parent and not fusing of gametes
