Cheaters, diffusion and nutrients constrain decomposition by microbial enzymes in spatially structured environments (2005, background): “However, constraints on enzyme production and function probably do limit the turnover of large quantities of organic matter (e.g. Freeman et al. 2001).”
Cell-wall polysaccharides play an important role in decay resistance of Sphagnum and actively depressed decomposition in vitro (2011, background): “In phenolics-dominated litter the shut-down of phenol oxidase under anaerobic water-logged conditions is an important latch on C-mineralization (Freeman et al. 2001) which is far less effective in polysac-”
RNA Stable Isotope Probing, a Novel Means of Linking Microbial Community Function to Phylogeny (2002, background): “, in peatland soils) represents a mechanism maintaining a significant sink in the global carbon budget (11).”
Effects of climate extremes on the terrestrial carbon cycle: concepts, processes and potential future impacts (2015, background): “The large carbon stocks stored in peatlands are mainly protected by decomposition-limiting low temperatures and/or high water levels (Freeman et al., 2001).”
Climate change feedbacks to microbial decomposition in boreal soils (2011, background): “Overall, these results suggest that decomposition of permafrost C is limited by low microbial activity, but high potential enzyme activity and an abundance of available C could result in rapid losses of soil C following permafrost thaw (Freeman et al. 2001, 2004).”
Biogeochemical cycles and biodiversity as key drivers of ecosystem services provided by soils (2015, background): “…periods, SOM decomposition is decreased, but after rewetting there may be an accelerated pulse of CO2 emission in aerobic soils (Borken and Matzner, 2008), whereas drought and lowering water tables may increase decomposition in naturally anaerobic peats (Freeman et al., 2001; Clark et al., 2012).”
Linking soil process and microbial ecology in freshwater wetland ecosystems (2006, background): “Finally, enzy- matic degradation of large polymers such as cellulose or chitin is particularly of interest in wetland and riparian soils as an indicator of biogeochemical cycling, and as a potential source of soil feedback to climate change (Dick and Tabatabai 1992; Freeman et al. 1997, 2001).”
Long-term increases in surface water dissolved organic carbon: observations, possible causes and environmental impacts. (2005, background): “Laboratory peat warming experiments showed increased phenol oxidase activity, DOC, and proportion of phenolic compounds within this DOC (Freeman et al., 2001b; Fenner, 2002), implying both a temperature effect on DOC production, and increased recalcitrance of that DOC, likely to limit further…”
