Competition - The theory of competition is an extension of the logistic growth model 𝑑𝑁 𝑑𝑡 ( = 𝑟𝑁 1 − 𝑁 𝐾 ) As population size approaches carrying capacity, the population becomes stable and an equilibrium is reached Extending the logistic growth model 𝑑𝑁 1 𝑑𝑡 𝑑𝑁 𝑑𝑡 2 =𝑟 =𝑟 1 2 𝑁 𝑁 ( ( 1 2 1− 1− 𝑁 1+𝑎𝑁 𝐾 1 𝑁 1+𝑏𝑁 𝐾 2 1 2 ) ) Competition coefficients - two variables that convert ( number of individual of species 1 and 2) A- effect of species 2 on species 1 A- effect of species 1 on species 2 Zero population growth isocline - population sizes at which a population experiences zero growth Solve for species 1 : N1=K1-aN2
