In Jpomz/IGPtoy: Simulate Intraguild Predation Dynamics in Three Species Community

Description

Set abundances to 0 when B goes extinct

Usage

B_extinct(N)

Arguments

N	Community abundance matrix with nrow = n_sp = 3 and ncol = n_patch

Details

This is an internal function which sets higher trophic levels (species C and P), to 0 in a patch when the abundance of species B is 0.

Value

Abundance matrix, N.

Examples

n_sp = 3
n_patch = 5
N <- matrix(rpois(n = n_sp*n_patch, lambda = 100), nrow = n_sp, ncol = n_patch)
N
# make a few Row 1 == 0
N[1, 1:2] <- 0
N
