getStarvMort: Get starvation mortality

In sizespectrum/mizerStarvation: Starvation mortality for mizer

Description

There is no starvation mortality as long as the energy income rate E_r is positive. For details of this rate see mizer::getEReproAndGrowth(). Once this rate is negative, the per-capita mortality is proportional to this rate and inversely proportional to body weight (and therefore also lipid reserves):

mu_s(w) = -E_r(w)/w * starv_coeff

The proportionality constant starv_coeff is set with setStarvation().

Usage

getStarvMort(
  params,
  n = params@initial_n,
  n_pp = params@initial_n_pp,
  n_other = params@initial_n_other,
  ...
)

Arguments

params	A MizerParams object
n	A matrix of species abundances (species x size).
n_pp	A vector of the plankton abundance by size
n_other	A list of abundances for other dynamical components of the ecosystem
...	Unused

Value

A two dimensional array of instantaneous starvation mortality (species x size).
