calcDensityDependentDeathRate function

Calculate Density-dependent Larval Mortality

Calculate $\alpha$, the strength of density-dependent mortality during the larval stage, given by: [REMOVE_ME]$\alpha=\Bigg( \frac{1/2 * \beta * \theta_e * Ad_{eq}}{R_m-1} \Bigg) * \Bigg( \frac{1-(\theta_l / R_m)}{1-(\theta_l / R_m)^{1/T_l}} \Bigg) [REMOVE_ME_2]$

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 $R_{m}$

Description
