This implements differential equation model for aquatic mosquito ecology. The equations have been modified slightly from a version published by Smith DL, et al. (2013); this version includes delayed maturation i in response to mean crowding.

Variables:

  • L: the density of mosquito larvae in each habitat

Parameters and Terms:

  • η or eta: egg deposition rate (from F_eggs)

  • ψ or psi: maturation rate

  • ξ or xi: delayed maturation parameter in response to mean crowding

  • ϕ or phi: density-independent death rate

  • θ or theta: the slope of the mortality rate in response to mean crowding

Dynamics:

dL/dt=η(ψeξL+ϕ+θL)L

Per-capita mortality is thus ϕ+θL, and the emergence rate of adult mosquitoes is ψeξLL

Usage

# S3 method for class 'basicL'
dLdt(t, y, pars, s)

Arguments

t

current simulation time

y

state vector

pars

an xds object

s

the species index

Value

a numeric vector
