    A. a and b only

    C. both species gain an advantage (in terms of survival and reproduction) from other species

    f. all of the above
    (this multiple choice question has been scrambled)

  9. In the yucca/yucca moth mutualism, yucca plants abort seed pods in which too many yucca moth larvae are maturing (and hence, only a very small number (or no) seeds). This is an example of:
    one species in a mutualism penalizing the other for "cheating"
  10. In models of disease, the threshold density of susceptible individuals (ST) is:
    can be reduced by adding susceptible (healthy) individuals to the population
  11. In disease ecology "SIR" models indicate that:
    host population size, as well as reproductive, death, and disease-recovery rates, are all important in predicting the negative consequences of different diseases in that population
  12. Which of the following is NOT a characteristic of metapopulation:
