In padpadpadpad/TeamPhytoplankton: For studies into thermal adaptation

Description

Models the thermal performance curve for metabolism using a modified thermal performance curve which includes inactivation of the rate at both low and high temperatures.

Usage

schoolfield(ln.c, Ea, El, Tl, Eh, Th, temp, Tc)

Arguments

ln.c	The specific rate of metabolism (log scale)
Ea	Activation energy
El	Low temperature deactivation energy
Tl	Temperature at which enzyme is 1/2 active and 1/2 low temperature suppressed
Eh	High temperature deactivation energy
Th	Temperature at which enzyme is 1/2 active and 1/2 high temperature suppressed
temp	Temperature in K
Tc	Standardisation temperature (in ºC, arbitrary)

Value

Returns a value of metabolism b(T) across the range of temperatures set based on the parameter values
