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