Lesson 7: Keystone Species & Ecosystem Resilience
Duration of Days: 3
Lesson Objective
Explain how the presence or removal of a keystone species or top predator impacts the short-term and long-term structure of an ecosystem.
Describe the direct relationship between ecosystem diversity and its resilience to environmental disturbances
Why do certain species exert disproportionately large control over their community structure relative to their abundance?
How does genetic, species, and ecosystem diversity influence a community's resilience to environmental change?
