solve_muAqua {MGDrivE2}R Documentation

Solve for Constant Aquatic Mortality

Description

In MGDrivE, the model was typically solved at equilibrium assuming the density-independent mortality was constant over aquatic stages (eggs, larvae, pupae), given a daily growth rate, rMr_{M}. Given that growth rate, it solved for that mortality μAqua\mu_{Aqua} by relating it with RMR_{M}, the per-generation growth rate of the population, calculable from rMr_{M} and the mean duration of life stages. This function uses uniroot to solve for muAquamu_{Aqua}.

Usage

solve_muAqua(params, rm)

Arguments

params

a named list of parameters

rm

the daily growth rate

Details

This function needs the following parameters in params:

Value

location of the root, as provided from uniroot

Examples

theta <- list(qE = 1/4, nE = 2, qL = 1/5, nL = 3, qP = 1/6, nP = 2, muF = 1/12,
             beta = 32, phi = 0.5);
muAqatic <- solve_muAqua(params = theta, rm = 1.096)
