Calculate Density-dependent Larval Mortality

Calculate \(\alpha\), the strength of density-dependent mortality during the larval stage, given by: $$\alpha=\Bigg( \frac{1/2 * \beta * \theta_e * Ad_{eq}}{R_m-1} \Bigg) * \Bigg( \frac{1-(\theta_l / R_m)}{1-(\theta_l / R_m)^{1/T_l}} \Bigg)$$

Usage

calcDensityDependentDeathRate(
  fertility,
  thetaAq,
  tAq,
  adultPopSizeEquilibrium,
  populationGrowthRate
)

Arguments

fertility

Number of eggs per oviposition for wild-type females, \(\beta\)

thetaAq

Vector of density-independent survival probabilities of aquatic stages, \(\theta_{e}, \theta_{l}\)

tAq

Vector of lengths of aquatic stages, \(T_{e}, T_{l}, T_{p}\)

adultPopSizeEquilibrium

Adult population size at equilibrium, \(Ad_{eq}\)

populationGrowthRate

Population growth in absence of density-dependent mortality \(R_{m}\)
