Sentences with phrase «slow decomposition rate»

It seems especially important in the light of the research and findings by Lehmann et al on black carbon in soils --- its very slow decomposition rate ---- and the fact that climate models may be over-estimating their global warming predictions, if they are not including «realistic stocks of black carbon in prediction models».

Ecologist team finds leaf litter has slower decomposition rate in warm temperatures than previously estimated

Not exact matches

They found that high rates of carbon accumulation in lake sediments were stimulated by several factors, including «thermokarst erosion and deposition of terrestrial organic matter, -LSB-...] nutrient release from thawing permafrost that stimulated lake productivity, and by slow decomposition in cold, anoxic lake bottoms.»

Wood decomposition rates also slowed; apparently, isopods can help counteract the effects of rising temperatures on the carbon stored in the world's forest soils.

Emissions of CO2 were highest from peat incubated in the localized permafrost feature, suggesting that slow organic matter accumulation rates are due, at least in part, to rapid decomposition in surface permafrost peat.
