calcDensityDependentDeathRate: Calculate Density-dependent Larval Mortality

Description

Calculate $\alpha$, the strength of density-dependent mortality during the larval stage, given by: $$\alpha =(\frac{1/2\ast \beta \ast {\theta }_e\ast A{d}_{eq}}{R_m-1})\ast (\frac{1-({\theta }_l/R_m)}{1-({\theta }_l/R_m{)}^{1/T_l}})$$

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, $A{d}_{eq}$

populationGrowthRate

Population growth in absence of density-dependent mortality $R_m$
