ftemp_inst_rd: Calculates the temperature response of dark respiration

Description

Given the dark respiration at the reference temperature 25 degress Celsius, this function calculates its temperature-scaling factor following Heskel et al. 2016.

Usage

ftemp_inst_rd(tc)

Value

A numeric value for \(fr\)

Arguments

tc

Temperature (degrees Celsius)

Details

To correct for effects by temperature Heskel et al. 2016, and given the reference temperature \(T0 =\) 25 deg C, this calculates the temperature scaling factor to calculate dark respiration at temperature \(T\) (argument tc) as: $$ fr = exp( 0.1012 (T0-T) - 0.0005(T0^2 - T^2) ) $$ where \(T\) is given in degrees Celsius.

Examples

## Relative change in Rd going (instantaneously, i.e. not 
## acclimatedly) from 10 to 25 degrees (percent change):
print( (ftemp_inst_rd(25)/ftemp_inst_rd(10)-1)*100 )
