9. Lotka-Volterra Competition Models

What will you learn in this lecture:

  • The mathematics underlying the graphical Lotka-Volterra competition model.
  • Ability to construct and interpret them and understand the conditions which lead to species exclusion and coexistence.

Enrolled students of fall 2024 should watch this lecture before October 15.

What questions should you be able to answer now?

  • Why is the model outdated, yet important to learn?
  • What are the variables we need to make the graphical model?
  • How does the model work for different values of K and population size?
