Description

Updates the species' population size. This change is a function of the number of individuals that grow out of their present size class and the number that remain.

Usage

1
calc_population_growth(nSize, nSpecies, N, probGrowOut)

Arguments

nSize

Number of size class intervals species can grow through

nSpecies

Number of species in the model

N

A matrix (nSize x nSpecies) of species abundance (number of individuals)

probGrowOut

A matrix (nSize x nSpecies) of proportions. Note: probGrowOut = 0 for size classes in which a species does not reach and probGrowOut = 0 for largest size class. It is not possible to grow out of the largest size class since it is determined by Linf. See calc_phi

Value

A list is returned

N

A matrix (nSize x nSpecies) of abundance (number of individuals)
