calc_E {respirometry}

Calculate E temperature coefficient

Description

An E value is a relatively recent metric to parameterize the temperature-sensitivity of a biological rate (MO2). It is similar conceptually (but not numerically) to Q10.

Usage

calc_E(x, temp)

Arguments

x

a numeric vector of rate values (e.g. MO2) or any other values (e.g. Pcrit).

temp

a numeric vector of temperature values (in Celsius).

Details

E is the slope of the relationship between -ln(x) and 1/(kB T), where kB is the Boltzmann constant expressed in eV/K.
