Description

Calculates the impact of prey on predator reproduction; see equation 12 of Punt et al. 2016

Usage

1
calc_phi(predator, Dy)

Arguments

predator

A Predator object

Dy

The relative (scaled) biomass of prey available to the predator. Note: we're using one set of thetas for all prey species, but we could potentially make them different for each prey (Punt et al. set them all equal in the base scenario.)

Value

The parameter phi
