mizer (version 2.0.0)

mizerPredMort: Get total predation mortality rate needed to project standard mizer model

Description

Calculates the total predation mortality rate \(\mu_{p,i}(w_p)\) (in units of 1/year) on each prey species by prey size: $$\mu_{p.i}(w_p) = \sum_j {\tt pred\_rate}_j(w_p)\, \theta_{ji}.$$

Usage

mizerPredMort(params, n, n_pp, n_other, pred_rate, ...)

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

pred_rate

A two dimensional array (predator species x predator size) with the feeding level.

...

Unused

Value

A two dimensional array (prey species x prey size) with the predation mortality
