Climate Change and Food Webs


A video of the Howard Hughes Medical Institute (HHMI) Biointeractive that describes the threats of climate change on the ecosystem of the Yellowstone National Park, USA. In this video, Elizabeth Hadley, Stanford University, discusses how climate change can lead to changes in habitats and species interactions.

Students will learn about how a warming climate potentially causes organisms to change their behaviour and alter the food web. They will understand these changes through an example of interactions between the whitebark pine trees, bark beetles, squirrels and grizzly bears in Yellowstone National Park, USA. They will also learn about aquatic habitat loss and threats to amphibian populations in the park.

Use this tool to help your students find answers to:

  1. Discuss how climate change is causing changes to the ecosystem of the Yellowstone National Park
  2. How is climate change affecting the food web? Discuss using the example of the bark beetle.
