Case study explores the interactions of wolves and moose on Isle Royale. Students examine data on population growth and spinal deformities caused by inbreeding.
This activity asks students to calculate the population change (births – deaths) and then graph the number of deer and the number of wolves.
This case study examines evolution in guppies as evidenced by color variation in populations. It is based on an iconic study performed by John Endler where he collected data on guppies by scoring the size, number, and brightness of spots. Students progress though the slides (lecture and discussion), and examine details of Endler’s study, such as where…
