Calculates the energy rate (grams/year) available for reproduction after growth and metabolism have been accounted for.
getERepro( params, n = params@initial_n, n_pp = params@initial_n_pp, n_other = params@initial_n_other, e = getEReproAndGrowth(params, n = n, n_pp = n_pp, n_other = n_other) )
| 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 |
| 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 |
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.
