Abstract:

This case study has students analyze real population and climate data to address a problem in conservation. Many elephant populations exist in Africa, but if a conservation group had funding to supply a grant to just one population, which one should it be? This activity uses a jig-saw approach in which students first assume the role of a conservation grant applicant, using data sheets (examples included in the teaching notes) and performing additional research about their assigned country to determine the elephant population for which they will advocate. Students then change roles and adopt the viewpoint of a conservation grant program representative who must determine which country should receive the grant. This activity was originally designed for a non-majors environmental science course and a science majors introductory organismal biology course. It is also suitable for use at the high school level.

Objectives:
  • Graph a natural population growth curve.
  • Explain if a natural population fits an exponential model, logistic model, or neither.
  • Estimate a natural population's carrying capacity.
  • Predict density dependent and independent factors that regulate a population.
  • Analyze climate data.
  • Use data to make informed conservation decisions.
  • Develop a visually-appealing and persuasive infographic.
