getERepro: Get energy rate available for reproduction

Description

Calculates the energy rate (grams/year) available for reproduction after growth and metabolism have been accounted for.

Usage

getERepro(
  params,
  n = initialN(params),
  n_pp = initialNResource(params),
  n_other = initialNOther(params),
  e = getEReproAndGrowth(params, n = n, n_pp = n_pp, n_other = n_other)
)

Arguments

params

A '>MizerParams object

n

A matrix of species abundances (species x size).

n_pp

A vector of the resource abundance by size

n_other

A list of abundances for other dynamical components of the ecosystem

e

The energy available for reproduction and growth (optional). A matrix of size no. species x no. size bins. If not supplied, is calculated internally using getEReproAndGrowth().

Value

A two dimensional array (prey species x prey size) holding $$\psi_i(w)E_{r.i}(w)$$ where \(E_{r.i}(w)\) is the rate at which energy becomes available for growth and reproduction, calculated with getEReproAndGrowth(), and \(\psi_i(w)\) is the proportion of this energy that is used for reproduction. This proportion is taken from the params object and is set with setReproduction().

Examples

# NOT RUN {
params <- newMultispeciesParams(NS_species_params_gears, inter)
# Project with constant fishing effort for all gears for 20 time steps
sim <- project(params, t_max = 20, effort = 0.5)
# Get the energy at a particular time step
getERepro(params,sim@n[21,,],sim@n_pp[21,])
# }
