VRM can be used to assess the level of decay of logs decayed in natural conditions.
The quantity of sawdust (DecSD_{p}) (MgC·ha(^{-1})) in the logging unit p at the year of logging (t0_p) is: begin{aligned} DecSD_{p} = (1-f_{SW}) times Ext_p end{aligned} (3 Sawnwood decay is approximated with an exponential decay.
We recorded the diameter and decay class of logs >7.62 cm diameter for any piece >1 m in length that intersected any transect.
A clear linear decay fit the log-log data well (with a R value of 0.78) in the case of GC pairs.
The level of decay of 60 small-diameter silver fir logs degraded in natural conditions in the French Northern Alps was assessed using both methods.
Consistent with the observed exponential decay, the log of distance from the freeway/ highway to a residence was a better predictor of NOx than the linear distance in univariate regressions.
To select genes whose mRNA were either destabilized or stabilized in differentiated cells in both LIF− and RA conditions, we used one standard deviation cut-off of log decay rates (Supplementary Fig. S5A).
The sensitivity analysis reveals three main sources of uncertainty in our model: deforestation, large woody necromass decay and logging damage (Fig. 10).
The quite slow decay of these woody debris and harvested logs is a long-term source of carbon to the atmosphere.
The second logging unit (with high logging intensity) has high emissions from damage decay in the first 8 years after logging, that exceed carbon accumulation from forest recovery: the carbon balance of the logging unit increases.
