Within naturally occurring temperature ranges, ecosystem respiration typically shows an exponential response to temperature29,30as described by the Arrhenius equation31(Methods). While components of ecosystem r
The Nernst equation was used to estimate the redox potential of each redox couple. This equation relates the change in free energy of the transfer of electrons to the voltage of an electrochemical cell, and can be expressed as:(2)ΔE=ΔE°−RTnFlnQ.ΔE° is the electromotive force under...
The empirically derived weighted model II equation (Fig.1b) of O2vs.TOC removal rates resulted in an intercept of −0.12 ± 0.02 µM O2 d−1, inferring that there were processes—other than complete bacterioplankton oxidation of DOM—contributing to the excess removal of O2rel...
Write the net equation for cellular respiration. How many ATP are produced? Balance the following equation for photosynthesis. CO2 + H2O arrow C6H12O6 + O2 What is the chemical equation for photosynthesis? Write it in symbols. What is the overall balanced chemical equation for p...
We simulated the dynamics of Re and its components during the growing season with a multi-factor equation, Rx = a exp (b PAR + c Ts + d SWC + e GLAI) (Table2). The goodness-of-fit values of the multi-factor equation were greater than 0.8 for Re, Ra, and Raa...
In the equation, α, r0, v, and Q10 are parameters, i is a chamber, and RWCi is the relative water content estimated using Eq. (2):(2)RWCi(t)=SWCi(t)−WPFC−WP In the equation, SWCiis measured soil water content, FCis field capacity, and WPis wilting point. We used 0.25...

Then, one-way anovas with Duncan's multiple-range tests were performed across all response variables to compare the effects of N and acid enrichment. Second, structural equation modelling (SEM) was performed to analyse different hypothetical pathways that may explain N enrichment linkages to soil ...
