A function for continuous logistic growth with the Allee effect, for use with ode
in the deSolve
package.
1 |
t |
Time points for which N wll be returned. |
y |
N, population size |
p |
a vector of logistic growth (r, alpha) and Allee effect parameters (a, tau); a is the threshold population size. |
The user does not put these directly into this function, but rather uses codeode in the deSolve
package.
The function is based on the logistic growth equation
\frac{dN}{dt} = rN≤ft(1-α N\right)≤ft(1 - \frac{a+τ}{N+τ}\right)
with a being the threshold population size.
