Sentence examples for litter fractions from inspiring English sources

SOM formation through a microbial-driven pathway cannot be ruled out for any biochemical fraction evaluated, but it seems more relevant for HWE and CF. In short-term, substrate biochemistry exerts a strong influence on the conversion of eucalypt litter fractions into either CO2 or SOM.

Carbon inputs estimated as NPPtotal (Table 2) and from the different litter fractions (Table 3) provided comparable results for organic soils (1206 and 1185 g C m−2 yr−1 for NPPtotal and NPPcombined, respectively).

According to the double exponential model, median leaf litter decay coefficients of the recalcitrant and the labile litter fraction were 0.006 d−1 (−0.017 to 0.016) and 0.15 d−1 (0.06–0.86), respectively.

The chronosequences showed that few species had significant effects with elapsed time since burning; the dominant Calluna vulgaris increased in the above-ground litter fraction which acted as a barrier to seed transfer to the underlying peat.

The above ground vegetation was sorted into the live fractions of functional groups (namely: grasses, herbs, Equisetum sp., deciduous shrubs and mosses) and the litter fraction was separated into the non-photosynthesising part of the moss (here after denoted 'brown' moss) and vascular plant litter.

The forest products techniques for analysis of litter C fractions were used to determine litter lignin and cellulose content [40].

Cells of fraction 1 (total ∼ 0.5 1×10 cells from five Col10CreYFP+ pups from the same litter) and fraction 2 (2 4×10 cells) were plated at 3 5×10 cells/well (F1) or 2 4×10 cells/well (F2) on fibronectin coated 12-well dishes for cell sorting of YFP+ cells.

The results reveal that although the main above-ground biomass was constrained in three fractions (litter, Calluna and bryophytes) there was no significant effect of sheep-grazing or its interaction with prescribed burning (graze × burn) on any biomass variables or vegetation height.

From this perspective of HFA, our results help understanding mechanisms of leaf litter soil feedbacks in grassland, including the return of carbon (C) to the soil through litter decomposition and fraction in functional microbial groups.

The variation due to litter explained a fraction of 0.07±0.009 of the total variation, much smaller than the genetic.
