To foster student understanding of this concept, instructors can choose an illustrative example such as:
• Invasive and/or eruptive species
• Human impact
• Hurricanes, floods, earthquakes, volcanoes, fires
• Water limitation
Mathematical models and graphical representations are used to illustrate population growth patterns and interactions.
Evidence of student learning is a demonstrated understanding of each of the following:
1. Reproduction without constraints results in the exponential growth of a population.
2. A population can produce a density of individuals that exceeds the system’s resource availability.
3. As limits to growth due to density-dependent and density independent factors are imposed, a logistic growth model generally ensues.
4. Demographics data with respect to age distributions and fecundity can be used to study human populations.
