How do populations change in the Hudson River ecosystem, and how do these changes affect the larger ecological community? Using video, data, and hands-on investigations, students will explore how food webs and the abiotic resources and conditions of the ecosystem have changed in response to the zebra mussel invasion. This case study allows students to understand community level changes, which they can then apply to other systems.
