Estimate the critical thermal minimum of a thermal performance curve

Description

Estimate the critical thermal minimum of a thermal performance curve

Usage

get_ctmin(model)

Arguments

model

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

Details

Optimum temperature is calculated by predicting over a temperature range 50 degrees lower than the minimum 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 value so the estimate of the critical thermal minimum should be accurate up to 0.001 ºC.

Value

Numeric estimate of critical thermal minimum (ºC)
