title: Supplement 1. Non-transformed data used in statistical analysis of the effects of temperature and resource utilization on bacterial production in two rivers.

description: File List EEA_data.txt Description The EEA data.txt file is a tab-separated ASCII file. The file contains the non-transformed data used in statistical analyses of the effects of temperature and resource utilization on bacterial production in two rivers. Rates measured in the lab at 20˚C were converted to rates at ambient temperature using the following equations: BP(T) = BP(T<sub>0</sub>)e<sup>-Ea/k</sup><sup>(1/T0-1/T)</sup> and <sup>App</sup>Vmax(T) = <sup>App</sup>Vmax(T<sub>0</sub>)e<sup>-Ea/k</sup><sup>(1/T0-1/T)</sup>, where BP represents bacterial production, <sup>App</sup>Vmax is the observed maximum extracellular enzyme activity (EEA) rate, T denotes ambient stream temperature (in K), and T<sub>0</sub> equals 293 K (or 20 ˚C); E<sub>a</sub> is the activation energy (eV) of the process, and k is Boltzmann's constant (8.62 x 10<sup>-5</sup> eV K<sup>-1</sup>). The activation energy (E<sub>a</sub>) was assumed to be 0.5 eV for bacterial production and maximum EEA rates.
