Topics Explored: K- and r- Selected Species, Survivorship Curves, Carrying Capacity, Population Growth, Endangered Species, Human Activities on Biodiversity, Math

This case study explores the population journey of the canada goose, hunted from an estimated population of 1 million to 100,000 by the late 1800s. With protection, the bird's population has exploded to over 7 million in 2023.   Answer key included.

    AP® Environmental Science Learning Objectives:
    3.2 Identify differences between K- and r-selected species.
    3.3 Explain survivorship curves.
    3.4 Describe carrying capacity. Describe the impact of carrying capacity on ecosystems.
    3.5 Explain how resource availability affects population growth.
    8.5 Explain the environmental effects of excessive use of fertilizers and detergents on aquaticecosystems.
    8.14 Identify sources of human health issues that are linked to pollution.
    9.9 Explain how species become endangered and strategies to combat the problem.
    9.10 Explain how human activities affect biodiversity and strategies to combat the problem.

    AP® Environmental Science Practices:
    1: Explain environmental concepts, processes, and models presented in written format. 
    2: Analyze visual representations of environmental concepts and processes. 
    3: Analyze sources of information about environmental issues. 
    4: Analyze research studies that test environmental principles. 
    5: Analyze and interpret quantitative data represented in tables, charts, and graphs.
    6: Apply quantitative methods to address environmental concepts.
    7: Propose and justify solutions to environmental problems.

    IB Environmental Systems Learning Objectives:
    2.1 A species interacts with its abiotic and biotic environments, and its niche is described by theseinteractions. Populations change and respond to interactions with the environment. Any systemhas a carrying capacity for a given species.
    2.2 The interactions of species with their environment result in energy and nutrient flows.
    2.3 Ecosystems are linked together by energy and matter flows.
    3.2 Environmental change gives new challenges to species, which drives the evolution of diversity
    4.4 Water pollution, both to groundwater and surface water, is a major global problem, the effects ofwhich influence human and other biological systems.
