The Dead Zone: Ecology and Oceanography in the Gulf of Mexico

This interrupted case study focuses on the seasonal hypoxic area in the Gulf of Mexico known as the Dead Zone. It follows Sue, a college student, whose father is a commercial fisherman affected by the lack of fish in his usual fishing grounds in the summer. In her quest to determine why the fish disappear, Sue learns about both the biological and physical forces that produce, maintain, and eventually dissipate the hypoxic zone. The case introduces students to the marine food web, the aquatic microbial loop, the impact of exogenous nutrients, and the physical forces that affect oxygen content and water stratification. It could be used in introductory biology or ecology courses or in an oceanography course. (less)

Fish as Fertilizer: The Impacts of Salmon on Coastal Ecosystems

Fish as Fertilizer: The Impacts of Salmon on Coastal Ecosystems

In this case study, students examine data from a number of published ... (more)

In this case study, students examine data from a number of published studies of the effects of Pacific salmon on freshwater and riparian ecosystems. The case focuses on the interesting phenomenon of spawning salmon acting as nutrient conveyor belts, transporting nutrients from the ocean upstream into freshwater spawning areas and, in some cases, even onto land, reversing the more-typical downstream movement of nutrients. As students work at analyzing and interpreting graphical data, they will also increase their understanding of the principles of biogeochemical cycling and gain an appreciation for the interconnectedness of different types of ecosystems. The topic is appropriate for any course covering ecosystem ecology including, for example, general ecology, freshwater or marine ecology, and environmental science. (less)

Fishing for Answers in the Gulf of Mexico's Dead Zone

Fishing for Answers in the Gulf of Mexico's Dead Zone

This "clicker case" addresses the eutrophication of aquatic systems caused by human activities. "Susan" is a biology student working at a seafood restaurant on the Gulf of Mexico. She discovers that the restaurant doesn't serve locally caught shrimp because shrimp populations are in decline. While searching for an explanation, Susan learns about the nitrogen cycle as well as interactions between species, the abiotic and biotic environment, and multiple ecosystems (terrestrial and aquatic). Developed for a large introductory biology course, the case combines the use of student personal response systems ("clickers") with case teaching methods and formats. It is presented in class using a series of PowerPoint slides (~3.8MB) punctuated by questions that students respond to using their clickers. The case could be adapted for use without these technologies. (less)

Is Iron Fertilization Good for the Sea?

Is Iron Fertilization Good for the Sea?

This case study describes experiments to seed the ocean with iron to encourage algae growth. It explores how human activities contribute to greenhouse effects and global warming, proposals to potentially counteract these effects and make the ocean more productive for commercial fishing, and the issues and possible unintended consequences of such activities. The case is appropriate for introductory biology, ecology, environmental biology, microbiology, and environmental microbiology classes as well as courses dealing with environmental policy. (less)

Search for the Missing Sea Otters: An Ecological Detective Story

Search for the Missing Sea Otters: An Ecological Detective Story

Using a progressive disclosure format, this case study teaches students how to ... (more)

Using a progressive disclosure format, this case study teaches students how to apply ecological principles to a real-life ecological problem, namely, the decline in sea otter populations in Alaska. Students interpret data from graphs and tables and practice developing testable hypotheses as they work in groups to solve the mystery of the "missing" sea otters. Designed to serve as a framework for teaching an ecology module to first-year biology majors, the case introduces students to basic concepts of population and community ecology. (less)
