Description

This resource is a case study learning activity to accompany the HHMI Video Some Animals Are More Equal than Others: Keystone Species and Trophic Cascades.

Notes

Despite the focus on terrestrial trophic cascades, the material was easy to apply to the water ecology course I utilized it in.  Students were then asked to apply the concepts to algae we were learning to identify and their predators in freshwater systems.
