get_ctmax {rTPC}

Estimate the critical thermal maximum of a thermal performance curve

Description

Estimate the critical thermal maximum of a thermal performance curve

Usage

get_ctmax(model)

Arguments

model

nls model object that contains a model of a thermal performance curve

Details

Critical thermal maximum is calculated by predicting over a temperature range 50 ºC beyond the maximum value in the dataset. The predicted rate value closest to 0 is then extracted. When this is impossible due to the curve formula (i.e the Sharpe-Schoolfield model), the temperature where the rate is 5 percent of the maximum rate is estimated. Predictions are done every 0.001 ºC so the estimate of the critical thermal maximum should be accurate up to 0.001 ºC.

Value

Numeric estimate of critical thermal maximum (ºC)
