Description

Models the thermal performance curve for metabolism using a modified thermal performance curve.

Usage

1
schoolfield.high(ln.c, Ea, Eh, Th, temp, Tc)

Arguments

ln.c

the specific rate of metabolism (log scale).

Ea

activation energy (eV)

Eh

high temperature de-activation energy (eV)

Th

temperature at which enzyme is 1/2 active and 1/2 suppressed due to high temperatures

temp

temperature in K

Tc

standardisation temperature (in degrees centigrade, arbitrary)
