CrashCourse
Key Concepts
- Conservation biology
- Restoration ecology
- Biodiversity (species, genetic, ecosystem)
- Extinction vortex
- Minimum viable population (MVP)
- Structural restoration
- Bioremediation
- Biological augmentation
Learning Objectives
- Define conservation biology and restoration ecology.
- Explain the importance of biodiversity at different levels (species, genetic, and ecosystem).
- Describe the concept of the extinction vortex and its impact on small populations.
- Calculate the minimum viable population size.
- Compare and contrast different restoration ecology strategies (structural restoration, bioremediation, and biological augmentation).
- To analyze case studies of conservation and restoration projects and evaluate their effectiveness.
Educator Instructions
- Introduction (5 mins)
Begin by introducing the topic of conservation and restoration ecology. Briefly explain how human activities have impacted ecosystems and the importance of protecting and restoring them. Show the Crash Course video. - Video Viewing and Note-Taking (13 mins)
Instruct students to watch the Crash Course video 'Conservation and Restoration Ecology'. Encourage them to take notes on key concepts, definitions, and examples provided in the video. - Discussion: Types of Biodiversity (10 mins)
Lead a class discussion focusing on the different types of biodiversity (species, genetic, and ecosystem). Ask students to provide examples of each and explain why each type is important for ecosystem health and resilience. - Activity: Case Study Analysis - Milltown Dam (15 mins)
Divide students into small groups and assign them the task of analyzing the Milltown Dam restoration project presented in the video. Ask them to identify the problem, the solutions implemented, and the potential benefits of the restoration efforts. - Explanation: Conservation Strategies (10 mins)
Explain small population conservation and declining population conservation. Discuss extinction vortex and how Minimum Viable population is calculated. - Explanation: Restoration Strategies (10 mins)
Explain structural restoration, bioremediation, and biological augmentation with examples. - Wrap-up and Quiz (7 mins)
Summarize the key concepts covered in the lesson. Administer the multiple choice quiz and the fill-in-the-blank quiz.
Interactive Exercises
- Create a Conservation Plan
Imagine a local ecosystem is threatened by development. Work in small groups to create a conservation plan. Include specific actions to protect the ecosystem and increase biodiversity. Present your plan to the class.
Discussion Questions
- How does habitat fragmentation affect genetic diversity within a species?
- What are some of the ethical considerations involved in restoration ecology (e.g., deciding which historical state to restore to)?
- Why is it considered easier to protect ecosystems than trying to fix them?
Skills Developed
- Critical thinking
- Problem-solving
- Data analysis
- Collaboration
- Scientific communication
