know everything else about these models, including what they predict, what assumptions they are
based upon, examples of populations that show these patterns of growth, etc. 8. Pay particular attention to the distinction between the population growth parameters: r(or rmaxR0, dN/dt, dN/Ndt. At what time scale is growth measured? When do you use R0or r? What are the units of time upon which they are measured?9. For r-selection and k-selection theory, know the following: 1) what does natural selection favor in each case, 2) under what circumstance (environmental conditions) should each type of selection be expected to occur, 3) what are the consequences for the loser in each type of selection, 4) what kind of traits should rand kselected species possess, 5) an example of a species that is either ror selected. 6) an example of a species that doesn’t fit perfectly into this dichotomy.), k6
10. For all topics that I have discussed in class I have tried to give examples from nature. For example, global human and black noddy populations grow in an exponential fashion. Make sure that you can also provide real-life examples of such things as directional natural selection, genetic drift, logistic growth, coevolution, intraspecific competition, etc. Only examples that have been scientifically demonstrated (in your lecture notes, or published in a peer-reviewed journal) will be accepted. You do not need to know the name of the author who conducted the study.11. Know your axes labels. You may be called upon to draw a survivorship curve, exponential growth curve, logistic growth curve or other assorted graphs. You will need to correctly label the axes. 12. STUDY YOUR NOTES! Unless I specifically stated otherwise, everything I said in class is fair game for your exam. Good luck with your studies!Example questions (drawn from quizzes and elsewhere):***Note: I will not post answers to these questions.1. See life table exercise (and answer key) I posted in Moodle.2. Based on John Endler’s (1980) work, what form of natural selection is operating on spot number in guppies?3. What is adaptive evolution? Provide one circumstance in which natural selection WILL NOT lead to adaptive evolution?4. Demographers often use the data from life tables to predict the long-term growth of a population. What are 2 of the major reasons why this can lead to erroneous predictions?
