Topics Explored: Biodiversity, Food Chains, Survivorship Curves, Ocean Warming

This case study explores the life history of the North Atlantic right whale (Eubalaena glacialis) and the history of whaling. Students will encounter a series of traditional and non-traditional representations of data, and compare and contrast K-selected species and r-selected species, survivorship curves, and the impact of human activities on whale populations. Answer key included.

    HS-LS2-1. Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.
    HS-LS2-2. Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales.
    HS-LS2-6. Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem.
    HS-ESS2-7. Construct an argument based on evidence about the simultaneous coevolution of Earth’s systems and life on Earth.
