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):
$$\mu_s(w) = \frac{-E_r(w)}{w} {\tt starv\_coeff} $$
The proportionality constant starv_coeff is set with setStarvation().
Usage
getStarvMort(
params,
n = initialN(params),
n_pp = initialNResource(params),
n_other = initialNOther(params),
t = 0,
...
)
starvMort(params, n, n_pp, n_other, t = 0, ...)Arguments
- params
A mizer::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
- t
The time for which to do the calculation. Defaults to 0.
