RickerRDD {mizer}

Ricker function to calculate density-dependent reproduction rate

Description

Takes the density-independent rates R_{di} of egg production and returns reduced, density-dependent rates R_{dd} given as

R_{dd} = R_{di} \exp(- b R_{di})

Usage

RickerRDD(rdi, species_params, ...)

Arguments

rdi

Vector of density-independent reproduction rates R_{di} for all species.

species_params

A species parameter dataframe. Must contain a column ricker_b holding the coefficient b.

...

Unused

Value

Vector of density-dependent reproduction rates.
