Calculates the consumption-rate-weighted mean trophic level of each species,
defined as
$$
T_i = \frac{\int r_i(w)\,N_i(w)\,T_i(w)\,dw}
{\int r_i(w)\,N_i(w)\,dw},
$$
where \(r_i(w) = (1 - f_i(w))\,E_i(w)\) is the consumption rate of an
individual of species \(i\) at weight \(w\), \(N_i(w)\) is the
abundance density, and \(T_i(w)\) is the size-resolved trophic level
from getTrophicLevel().
Usage
getTrophicLevelBySpecies(
params,
n = initialN(params),
n_pp = initialNResource(params),
n_other = initialNOther(params),
...
)Arguments
- params
A MizerParams object.
- n
A matrix of species abundances (species x size). Defaults to the initial abundances stored in
params.- n_pp
A vector of the resource abundance by size. Defaults to the initial resource abundance stored in
params.- n_other
A named list of the abundances of other dynamical components. Defaults to the initial values stored in
params.- ...
Unused
