Competitive Exclusion Calculator
Apply the Lotka-Volterra competition model to predict whether species will coexist or one will exclude the other.
Species 1 Parameters
Species 2 Parameters
Competition Coefficients
Lotka-Volterra: dN/dt = rN(K-N-αN')/K
α = competitive effect of other species relative to conspecifics
Competition Outcome
Stable coexistence possible
Niche overlap: 69.3%

Coexistence Conditions
K1 > α12 × K21000 > 640
K2 > α21 × K1800 > 600
Gause's Principle:
Species partition resources sufficiently - stable coexistence is possible
