For each species, returns the rate at which biomass is lost due to predation mortality.

Usage

getM2B(params)

Arguments

params

A MizerParams object

Value

A named vector of biomass loss rate due to predation mortality for each species

Details

This is calculated as $$M2B_i = \int_{w_0}^{w_{max}} \mu_{p.i}(w) N_i(w) w dw$$ where \(\mu_{p.i}(w)\) is the predation mortality rate of an individual of species \(i\) and weight \(w\) (obtained with getPredMort) and \(N_i(w)\) is the number density of species i at weight w.
