  1. The LAST Quiz! Lecture Quiz 6 Jeopardy

  2. `

  3. Provide the equations for geometric growth, exponential growth,and logistic growth.

  4. Geometric: Nt= NoλtExponential: dN/dt= rmaxNLogistic: dN/dt= rmaxN(1-N/K)

  5. Compare and contrast three adaptations of predators and prey

  6. Predators: Acute senses, Forward-facing eyes, VenomPrey: Adapted coloration, Defensive structures, Outward-facing eyes

  7. Explain a scenario that describes the confusion effect

  8. Many prey together get attacked by a predator. All prey run in different sporadic directions, and the predator can’t lock onto one to attack. Increases the chance for prey survival.

  9. Contrast interference competition and resource competition, and provide one example of a species experiencing that competition for each

  10. Interference – Active behavior to alter competitors’ use of a resource (Damselfish compete for space)Resource – Use of the same resources (Trees sharing light or nurients)

  11. Provide the equations used to calculate each of these factors:Net Reproductive RateMean Generation TimePer Capita Rate of IncreasePopulation Size Change Over Time

  12. Net Repro Rate: Ro =∑lxmxAvg. Gen Time: T = ∑ xlxmx / RoPer Cap. Rate Increase: r = ln Ro / TPop Size Change: dN/dt = B - M + I - E

  13. The concept of a Hypervolume of a niche belongs to who?

  14. G.E. Hutchinson

  15. Provide all of the beneficial/harmful types of predator prey interactions (+/-/0) and provide a real-life example of one of them

  16. 0 0 neutralism- - competition+ + mutualism+ - predation, parasitism+ 0 commensalism- 0 amensalism

  17. Define the Competitive Exclusion Principle

  18. Strongly competing species cannot persist (one will be eliminated)

  19. Provide a definition for each of the following variables pertaining to population growth:RoxlxMxTr

  20. Ro = Net reproductive ratex = Age interval in yearslx = % pop. surviving to each age (x)Mx = Average number eggs produced by each individual in each age categoryT = Average Generation Timer = Per Capita Rate of Increase

  21. List the 3 types of defensive mechanisms used by prey against predators

  22. BehaviorChemicalsMorphology

  23. Provide one example of predator prey interactions discussed in class, and explain whether or not that predator affects the population size of its prey completely

  24. Snowhare-Lynx:Predators alone did not control prey population size, but predation coupled with food supply had a large effect

  25. Define allelopathy

  26. Plants produce chemicals that inhibit competing plant growth

  27. Define Elton’s concept of a niche and explain what might happen if two species share the same niche

  28. The functional role of an organism in its community. Two species sharing a niche will experience interspecies competition

  29. Distinguish cryptic from aposematic coloration

  30. Cryptic: Camouflage to blend in with its surroundingAposematic: Warning coloration to deter predators

  31. List the 3 types of mimicry, and explain the scenario in which they would occur

  32. Batesian: Palatable mimics unpalatableMullerian: Unpalatable mimics unpalatableMertensian: Deadly mimics unpalatable

  33. Define Pollination Syndrome

  34. A match between pollinator morphology and flower morphology

  35. Define the term carrying capacity (K)

  36. The number of individuals of a population the environment can support

  37. Why are some plants predators?

  38. To manually acquire nutrients

  39. List the 3 hunting types, and provide on example of an animal that performs that type for each.

  40. Pursuit (Hawk)Stalk (Crane)Ambush (Alligator)

  41. Define Ectomycorrihzae and Arbuscular mycorrhizae

  42. Ectomycorrhizae: form a sheath around plant roots; grow between root cells; some may penetrate into root cells Arbuscular mycorrhizae: penetrate into cortex of the root, form special structures called arbuscules
