Integrative Biology 102: Lecture Outline Population Ecology Lecture Objectives By the end of the lecture, you should be able to: 1. list and explain factors that produce changes in population size. 2. contrast a J-shaped population growth curve with an S-shaped population growth curve. 3. indicate which part of an S-shaped growth curve represents biotic potential, environmental resistance, and carrying capacity. 4. distinguish between density-dependent and density-independent factors and give examples of each using plants and people. 5. contrast the effects of density-dependent and -independent factors on population growth. 6. Contrast r- and K-selected species. Reading: Ch. 6.
