Sentence examples for mean stem biomass from inspiring English sources
Data represent mean stem biomass composition with standard error of the mean shown in parentheses.
The stem BEF value was 0.7334 Mg m−3, which meant that stem biomass (in Mg) was 0.7334-fold larger than stem volume (in m3).
The stem BEF value was 0.7334 Mg m−3, which meant that stem biomass (in Mg) was 0.7334-fold larger than stem volume (in m).
(3) In the secondary plots, there were no stems larger than 29 cm dsh at breast height, which lead to a much smaller mean stem size and lower basal area, above-ground biomass, and canopy closure compared to the primary plots at both sites.
In terms of the mean absolute percentage error (MAPE), AGB, total biomass and stem biomass were estimated with less error (MAPE <20%) compared to coarse root dry weight (MAPE = 21%).
Where radial gradients are present, mean stem density increases or decreases with stem size and thus estimates of stem biomass and in turn carbon based on a mean species density become inaccurate (Nogueira et al., 2008).
As for stem wood biomass, since the difference between stem wood and stem biomass is negligible.
Stem wood volume was then multiplied by the basic stem density to estimate stem biomass.
The whole tree biomass in stem, branches, foliage, and roots was estimated by multiplying stem biomass by EF.
(2) The mean stem size was similar between the primary Maquipucuna plots and the Yanacocha plot, but the Yanacocha plot had more total stems and more stems in each size category, which lead to more basal area, above-ground biomass, and canopy closure at Yanacocha compared to Maquipucuna.
