Course Description 

This course is an introduction to ecology and ecosystem dynamics using a systems thinking lens. Learners will explore how scientists study various ecosystems around the world—from Mozambique's Gorongosa National Park, to the Hudson River in New York, to Caribbean coral reefs—and investigate the complex array of factors that inform management efforts. At the end of the course, learners will be able to grapple with real-world conservation questions, such as whether an ecosystem can recover from anthropogenic disruption and what role humans can, and should, play in that recovery.

Weekly Overview and Expectations

Week 1: Can an ecosystem recover?

We begin in Gorongosa National Park, Mozambique, and pose the question: Can this ecosystem recover after a 15-year civil war? To answer this question, learners must first consider what they need to know—what are the parts that make up this ecosystem, and how do they interact and work together? How do ecosystems react to disruption? How do we know? We will begin to explore the ecosystem as a dynamic whole rather than as a collection of parts, considering  how changes might affect the system in a variety of ways. This application of a systems thinking lens to understanding ecosystems will be a common theme throughout the course.

Learners will:

• Define what an ecosystem is and apply this definition to a real-life example, identifying some of an ecosystem’s unique components and the relationships among them.

• Reflect on how changes in an ecosystem can have varying effects, and begin to consider the system as a dynamic whole rather than a collection of parts.

Week 2: How do we study populations?

This week, we narrow the focus to populations within ecosystems. Who or what populates an ecosystem, and what are their roles? How do these roles change over time? What happens when a species is removed from a system? How do scientists study the populations within an ecosystem, from its largest to its smallest inhabitants? Learners will look for patterns in their own observations using the Wildcam Gorongosa (a series of remote trail cameras throughout Gorongosa National park) and then use the week’s resources to understand population dynamics. Learners will explore the important roles different species can play—such as ecosystem engineers, keystone species, and indicator species—and how they shape their ecosystems.

Learners will:

• Explore how species are adapted to their environments.
• Describe or predict how a population will change over time -- graphically, verbally, or quantitatively.
• Illustrate the different roles species can play and how these help shape a system (e.g., keystone species, indicator species).

Week 3: How do species coexist?

Last week we looked at what happens when a population is removed from an ecosystem, but what happens when you add a population? How does it affect the other players? This week we focus on community ecology and further explore the interactions between species in an ecosystem. We begin a two-week investigation into the Hudson River ecosystem, where a zebra mussel invasion has had cascading effects. Learners will apply their new understanding of species interactions to interpret real data on the dynamics within the river community.  

Learners will:

• Classify interactions between species by how they affect each other directly, indirectly and whether in positive, negative or neutral ways, and reflect on the complex, shifting nature of these classifications.
• Predict the impact of the addition or loss of a species on an ecosystem.
• Describe the different ways a habitat can be partitioned as species occupy different niches, such as spatially, temporally, or by diet.

Week 4: How is an ecosystem a system?

This week, learners will further their understanding about what makes an ecosystem a system by examining the flow of energy and matter through different parts of the environment. This includes understanding the interactions of biotic and abiotic factors within an ecosystem and the services each component provides. Continuing our investigation into the Hudson River ecosystem, learners will look at the short-term and long-term impacts of a disturbance on an aquatic ecosystem and its resilience. We will also be introduced to the complicated effects of both abiotic (climate change) and biotic (herbivory) interactions within a coastal salt marsh system, touching on ecological concepts of thresholds in a system and ecosystem resistance and resilience.

Learners will:

• LG1: Describe how matter and energy move in an ecosystem, connecting biotic and abiotic components and reflecting on the complexity of interactions.
• LG2: Explore how the interactions within an ecosystem results in functions and services, and consider the factors that influence an ecosystem’s resilience to change.
• LG3: Study a real-life case of a functioning ecosystem and analyze how its response to disturbance exhibits system-like properties.

Week 5: How are humans part of the ecosystem?

This week we turn to the role of humans in ecosystems: how humans interact with and are shaped by their environments. We explore the meaning of the “anthropocene” (the title given to the current geological age in recognition of significant impact of human activities) and investigate management approaches that balance human needs and biodiversity. A case study looks at the interplay of  biodiversity conservation and  local fishery activities using marine reserves. Learners will begin to grapple with the difficulty of implementing conservation solutions in the face of complex or “wicked” problems.

Learners will:

• Investigate the concept of the “anthropocene” and how humans influence—and are influenced by —their environments.
• Explore how humans manage their environments and evaluate the trade-offs between conservation and development goals, for a particular case study.

Week 6: Reprise: Can an ecosystem recover?

We return to Gorongosa National Park to wrap up the course. The conversation shifts from "Can an ecosystem recover?" to "Should it recover?" and "What does a successful recovery look like?" We explore how conservation might have to adjust to future challenges such as climate change, extinctions, and human population growth. We also introduce the idea that a spectrum of conservation approaches is necessary, from the preservation of land and species, to the integration of biodiversity into market economies, to the creation and management of “novel” ecosystems. Learners return to their concept maps from the beginning of the course to incorporate their new expertise.

Learners will:

• Appreciate how the diversity of human values and culture affects decisions about ecosystem management.
• Reconsider the implications of ecosystem recovery and reflect on what changed in their understanding of ecosystems and their dynamics.
• Demonstrate how course participants can apply the concepts from the course to their teaching of ecology.
