Ecosystem Dynamics: Seasonal Changes and Disturbances Analysis

Explore the impacts of seasonal changes and disturbances on ecosystems through computer modeling. Understand carbon transformations, energy fluxes, and ecosystem resilience. Compare different models, learn about carrying capacities, and analyze the effects of press and pulse disturbances. Engage in environmental literacy discussions to grasp the dynamic nature of ecosystems.

  3. Computer Model for Seasons and Disturbances Read the handout until Section A to review the Constant Flux and Changing Fluxes Simulations. What did you learn from the first two simulations? How is Model 3 different?

  4. The Seasons Model 3 without seasonal variation • Carrying capacity = 90 kg/yr • Atmospheric pool = 500 kg • Organic carbon pool = 500 kg

  5. Question 1

  6. The Seasons Model 3 with seasonal variation • Carrying capacity = 90 kg/yr • Atmospheric pool = 500 kg • Organic carbon pool = 500 kg

  7. Question 2

  8. Question 3

  9. Press and Pulse Disturbances

  10. Disturbances in Real Ecosystems Read about disturbances in real ecosystems. What are some examples of press and pulse disturbances? Record your answer for Question 6 on your worksheet.

  11. Discussion • How do the pools and fluxes change during seasons? Why? • How do disturbances affect ecosystems?
