Population Ecology
Exercise 1: Modeling Population Growth
Questions
A. How many generations did it take to reach a population size of 100?
B. Consider the mode of reproduction modeled in your population. Would sexual reproduction or asexual reproduction likely be the cause of a birth? Are individuals of the species likely or unlikely to have separate male and female sexes?
C. Did the modeled population exhibit linear growth, exponential growth, or no pattern? Use
Data Table 2 to support your answer.
D. Were changes in population size greatest when the population was smaller or larger? Which generation exhibited the greatest change in size? Use Data Table 3 to support your answer.
E. What resource constraints were placed on the modeled population?
F. Could the modeled population exhibit indefinite growth? If so, how? Is indefinite growth observed in nature? Explain why or why not.
Exercise 2: Investigating a Human Population
Questions
A. Which cohort had the greatest probability of death? Which had the least probability? Use the graph in Data Table 7 to support your answer.
B. Overall, does human mortality tend to be greatest at young ages or older ages?
C. How many individuals were male, and how many were female? How many individuals were you unable to assign a gender to?
D. Using the raw data in Data Table 4, calculate the average age at death for males and for females. What inferences can you make about male versus female age at death?
E. If the government made significant cuts in social services, such as prenatal and infant care, how might your data be affected?
