  • Exploring Trophic Cascades

    Exploring Trophic Cascades

    Click & Learn

    This interactive explores examples of what can happen when there are changes in the population size of one species in an ecosystem. How are species at other trophic levels affected? How does the ecosystem change?

  • Human Impacts on Biodiversity

    Human Impacts on Biodiversity

    Activity

    In this activity, students will use trail camera data to answer a scientific research question about the impacts of humans on species diversity in Gorongosa.

  • Discovering Keystone Species

    Discovering Keystone Species

    Poster

    This classroom poster illustrates Robert Paine’s pioneering experiment that demonstrated the importance of top-down regulation of ecological communities by predators and led to his coining of the term keystone species.

  • Film Guide for Some Animals are More Equal than Others

    Film Guide for Some Animals are More Equal than Others

    Film Guide

    The following classroom-ready resources complement the film Some Animals Are More Equal Than Others: Trophic Cascades and Keystone Species. It tells the story of the bold experiments by Robert Paine and James Estes, which established the importance of keystone species in regulating ecological communities and the cascades of effects set in motion by their removal.

  • Some Animals Are More Equal than Others: Keystone Species and Trophic Cascades

    Some Animals Are More Equal than Others: Keystone Species and Trophic Cascades

    Short Film

    (19 min 29 sec) Keystone species and trophic cascades are fundamental concepts in ecology. This short film tells the story of how these concepts were first established through the pioneering experiments of two young researchers: Robert Paine and James Estes.

  • Lesson 8 - WildCam Gorongosa: Data Analysis

    Lesson 8 - WildCam Gorongosa: Data Analysis

    Activity

    In this activity, students will collect actual data from WildCam Gorongosa and use those data to create graphs and answer an ecological question of their choice.

  • Lesson 7 - Observations Across Habitats

    Lesson 7 - Observations Across Habitats

    Activity

    In this lesson, students will compare wildlife in two different habitats by making observations using sets of trail camera photos. They will then use these observations to formulate questions for further study.

  • Lesson 4 - Gorongosa's Food Webs

    Lesson 4 - Gorongosa's Food Webs

    Activity

    In this lesson, students will learn about how food webs are constructed and trophic levels in an ecological community. They will then use animals that they identify in WildCam Gorongosa to construct food chains and food webs, and study the impacts of disturbances.
