Description

This activity guides the analysis of a published scientific figure from a study about Arctic fox populations and their main prey, lemmings.

Population sizes of predators and their prey often rise and fall together, following predictable patterns over time. In this study, scientists compared the population densities of one predator, the Arctic fox, and its prey, the collared lemming, in the High Arctic tundra of northern Greenland. The figure shows the population densities of the lemmings plotted against the corresponding densities of Arctic fox offspring.

The “Educator Materials” document includes a captioned figure, background information, graph interpretation, and discussion questions. The “Student Handout” includes a captioned figure and background information.

Student Learning Targets

  • Analyze and interpret data from a scientific figure. 
  • Describe the cause-and-effect relationship between predator and prey population dynamics.

Estimated Time

Within one 50-minute class period.

Key Terms

density dependence, logarithmic scale, nonlinear regression, population density, scatter plot, time lag
