Description

Discrete-time model with an allee effect for alpha > 1 with harvest control

Usage

1
Myer_harvest(x, h, p)

Arguments

x

the current population level

h

total harvest level

p

vector of parameters c(r, alpha, K)

Details

A Beverton-Holt style model with Allee effect. Unharvested carrying capacity is: K <- p[1] * p[3] / 2 + sqrt( (p[1] * p[3]) ^ 2 - 4 * p[3] ) / 2 The (unharvested) allee theshold is given by: x = p[1] * p[3] / 2 - sqrt( (p[1] * p[3]) ^ 2 - 4 * p[3] ) / 2

Value

the population level in the next timestep
