t_corr: Temperature Correction factor

Description Usage Arguments Value Warning Author(s) References Examples

Description

calculates de correction factor for the parameters and variables that are temperature dependent at the given temperature/s. DEB theory uses the Arrhenius concept of enzyme activation to incorporate the effect of temperature on the metabolic processes. The DEB model uses alternative variations of Arrhenius / van 't Hoff equations to calculate a curve for temperature sensitivity given by 5, 3 or only 1 parameter.

Usage

1
t_corr(p, Ti)

Arguments

p

a list containing a vector t.pars, as the one yielded using the function 'get_DEB_pars'. Alternative a vector containing 2 (T_ref, T_A), 4 (T_ref, T_A, T_L, T_AL) or 6 (T_ref, T_A, T_L, T_H, T_AL, T_AH) parameters

Ti

a single value or a vector containing the aimed temperature or temperature/s in Kelvins

Value

TC

A single value or a vector containing the correction factor/s for the given temperature/s

Warning

Temperature parameters should be given in the same order referred in the argument section
