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)
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.
Value
A numeric value for fr

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 )
