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
