Study Notes
Global Change Ecology Exam Study Guide
- Exam Format: Multiple choice, approximately 80-85 questions. No short answer questions.
- Content Focus: Primarily from PowerPoint slides (lectures 1-11 and since midterm), readings, quizzes, previous exams, and visitor presentations.
- Emphasis: First 4 course lectures and 7 lectures since the midterm. Graphs and images from PowerPoints, especially those crucial for understanding. Some recent "in the news" or student-presented slides will not be on the exam.
-
Key Lecture Concepts:
- Biodiversity: Four components (genetic, species, ecosystem, and functional).
- Population Size Importance: Small populations at greater risk of inbreeding, diversity loss, and extinction.
- Eutrophication: Nutrient runoff (nitrogen, phosphorus) causing algal blooms and oxygen depletion.
- Nutrient Cycles: Nitrogen fixation and phosphorus cycling from atmosphere and rock weathering, essential to organisms and ecosystems.
- Greenhouse Gases: CO2, CH4, N2O, and H2O vapor, properties, relative abundance, and warming potential.
- Ozone Layer Function: Blocks harmful UV radiation.
- Biodiversity Loss Drivers: Habitat loss, overexploitation, pollution, invasive species, and climate change.
- Coral Reef Decline: Bleaching from warming oceans, acidification, and pollution.
- Ocean Acidification: CO2 absorption lowers pH, harms marine life.
- Sustainable Harvesting: Practices to prevent depletion.
- Maximum Sustainable Yield (MSY): Largest sustainable yield a resource can provide.
- Tragedy of the Commons: Overuse of shared resources.
- Ecosystems: Impacts of exotic/invasive species, biotic homogenization, and strategies for increasing crop yields.
- Food Production: Dietary transitions, greenhouse gas emissions from different aspects (food production, storage, transport, and waste reduction), methods for minimizing pest damage.
- Climate Change and Global Warming: Extreme temperature changes and impacts on different ecosystems like polar regions.
- Ecological Catastrophe: Possible impact caused by exceeding boundary limits.
- Biodiversity Loss Drivers: Major drivers of mass extinctions- (meteor strikes, marine anoxia, ecological dominance of a single species, periods of elevated CO2 levels, and periods of elevated volcanic activity).
- Keystone Species: Crucial to ecosystem function.
- Conservation Techniques: Re-wilding, in-situ and ex-situ conservation.
- People in Study Guide: Greta Thunberg, Elizabeth Kolbert, Gene Likens, Margaret Meade, James Porter, Doug Tallamy.
- Readings and Videos to Review: Several videos and readings, including "Death by a Thousand Cuts" (Wagner) and "Greenland" (Kolbert).
- Important Videos/Readings Links: Provided.
