Discussion of trends in the wildebeest population over time is included

Discussion of possible factors that could cause an animal population, like wildebeest, to increase is included

Description of the trends in rinderpest prevalence over time and how the trends relate to the vaccination program that began in the 1950s is included

Explanation of how vaccinating cattle, but not wildebeest, could have caused the change in rinderpest prevalence in wildebeest is included

Discussion of what was limiting (i.e., regulating) the wildebeest population before 1960, identification as a density-dependent or density-independent factor, and explanation are included

Carrying capacity of the wildebeest population is identified with justification of trends from the graph

Discussion of what was limiting (i.e., regulating) the wildebeest population after 1980, identification as a density-dependent or density-independent factor, and explanation are included

Model that includes rinderpest, wildebeest, grass, fire, and trees, arrows to show the positive or negative effects (not energy flow), arrow labels with + or - to indicate positive or negative effects are included
