devRateIBMparam: Forecast ectotherm phenology as a function of temperature and development rate models using known parameters

Description

Forecast ectotherm phenology as a function of temperature and development rate models using known parameters

Usage

devRateIBMparam(
  tempTS,
  timeStepTS,
  eq,
  myParam,
  numInd = 10,
  stocha,
  timeLayEggs = 1
)

Value

A list with three elements: the table of phenology for each individual, the models used (nls objects), and the time series for temperature.

Arguments

tempTS

The temperature time series (a vector).

timeStepTS

The time step of the temperature time series (a numeric with 1 = one day).

eq

The name of the equation (e.g., lactin2_95).

myParam

The known parameters for the equation (a list of list for each life stage).

numInd

The number of individuals for the simulation (an integer).

stocha

The standard deviation of a Normal distribution centered on development rate to create stochasticity among individuals (a numeric).

timeLayEggs

The delay between emergence of adults and the time where females lay eggs in time steps (a numeric).

Details

Please note that this function is experimental and only works for the briere2_99 equation.

Examples

# with only one life stage
forecastX <- devRateIBMparam(
  tempTS = rnorm(n = 20, mean = 20, sd = 1),
  timeStepTS = 10,
  eq = briere2_99,
  myParam = list(
    list(
      aa = 0.0002,
      Tmin = 10,
      Tmax = 36.1,
      bb = 2.84)
  ),
  numInd = 10,
  stocha = 0.015,
  timeLayEggs = 1
)
# with two life stages
forecastXX <- devRateIBMparam(
  tempTS = rnorm(n = 20, mean = 20, sd = 1),
