Simulate the Lotka-Volterra competition model for two populations.
1 |
n01 |
initial population for the superior competitor species. |
n02 |
initial population for the inferior competitor species. |
tmax |
maximum simulation time. |
r1 |
intrinsic growth rate for the superior competitor species. |
r2 |
intrinsic growth rate for the inferior competitor species. |
k1 |
carrying capacity for the superior competitor species. |
k2 |
carrying capacity for the inferior competitor species. |
alfa |
alfa coefficient. |
beta |
beta coefficient |
The Lotka-Volterra competition model follows the equations:
SP1:
dN_1/dt = r_1*N_1*((K_1-N_1-alpha*N_2)/K_1)
SP2:
dN_2/dt = r_2*N_2*((K_2-N_2-beta*N_1)/K_2)
'compLV' returns a graph of the population size in time, and a graph with the isoclines of the equilibrium for both species. 'compLV' also returns an invisible matrix with the population size of each species in time.
