modelBriere1999: Briere 1999 Model

In aleblancbio/timescale: A package for development time calculation and other time scalings

Briere 1999 Model

Description

Correspond to the non-linear model of Briere et al. (1999), describing growth rate in function of temperature.

Usage

modelBriere1999(temp, param = list(a, T0, TL, m), control = list())

Arguments

temp	numeric vector of temperature (in celcius)
param	list of parameters named: T0 the base temperature under which no development occurs, TL the temperature above which no development occurs, a a normalizing factor such as development is completed at 1, m a constant determining the shape of the function.
control	list of arguments that control the behaviour of the model; empty, kept for consistency with the general structure of rate models.

Details

The function correspond to equation of (2) of Briere et al. (1999), the rate is r(T) = a*T*(T-T0)*(TL-T)^(1/m) if T0 <= T <= TL and zero otherwise. Setting m = 2 correspond to equation (1) of the paper.

Value

return a vector of rate associated to each element of temp.

Examples

modelBriere1999(temp = seq(8,32,2), param = list(a = 1/100, T0 = 10, TL = 30, m = 2))
