The oribatid mite Scheloribates moestus (Acari: Oribatida) alters litter chemistry and nutrient cycling during decomposition (2011, background): “Recent studies have shown that ecosystemN enrichment (Neff et al., 2002; Gallo et al., 2005; Grandy et al., 2008) and agricultural conversion (Grandy et al.”
Integrating microbial ecology into ecosystem models: challenges and priorities (2012, background): “In addition, C and N fluxes into the recalcitrant pool are allowed to increase as N availability rises, based on empirical findings from natural ecosystems (e.g., Neff et al. 2002; Nowinski et al. 2009).”
Microbial nitrogen limitation increases decomposition. (2007, background): “…that ecosystem C storage would increase with greater N availability as mining of recalcitrant C for N was suppressed, which might explain observed declines in decomposition with N addition (Berg and Matzner 1997, Magill and Aber 1998, Neff et al. 2002, Hagedorn et al. 2003, Wang et al. 2004).”
Evolutionary-Economic Principles as Regulators of Soil Enzyme Production and Ecosystem Function (2010, background): “Thus, the enzyme-mediated effect of N deposition on soil C cycling depends on the chemical quality of the litter and soil organic matter in a given ecosystem (Carreiro et al. 2000; Neff et al. 2002; Waldrop et al. 2004b).”
The Role of Microbial Communities in the Formation and Decomposition of Soil Organic Matter (2010, background): “…declines in the decomposition of soil humus (Berg and Matzner 1997; Michel and Matzner 2002) and increases in formation of refractory soil carbon (Neff et al. 2002; Resh et al. 2002; Dijkstra et al. 2004; Hagedorn et al. 2003) under conditions of high nitrogen deposition, fertilization, or…”
Fifteen years of climate change manipulations alter soil microbial communities in a subarctic heath ecosystem (2007, background): “…N additions to alpine tundra soil of the Rocky Mountains reduced microbial biomass and activity (Schmidt et al., 2004), although the decomposition of light soil C fractions including polysaccharide and lignin plant biomarkers was stimulated (Neff et al., 2002), which would indicate the opposite.”
Soil carbon stocks in experimental mesocosms are dependent on the rate of labile carbon, nitrogen and phosphorus inputs to soils (2008, neutral): “Indeed, SOC is not a single entity but rather a conglomeration of multiple pools of C cycling at different rates (Agren & Bosatta 2002; Kirschbaum 2004; Eliasson et al . 2005; Knorr et al . 2005b), each of which may respond differently to changes in resource availability (Cardon et al . 2001; Neff ”
Ecosystem feedbacks and cascade processes: understanding their role in the responses of Arctic and alpine ecosystems to environmental change (2009, background): “However, Neff et al. (2002) demonstrated that, in addition to increased productivity, decomposition of the light fraction of SOM increased, resulting in no statistically significant changes in SOM pools.”
Functional Matrix: A Conceptual Framework for Predicting Multiple Plant Effects on Ecosystem Processes (2003, background): “Just as with recalcitrant litter, degradation of organic matter can be influenced by labile C inputs or inorganic N availability (Bottner et al. 1999, Mueller et al. 1998), with the effects of these differing depending on the pools of C being degraded (Neff et al. 2002).”
The role of wood decay fungi in the carbon and nitrogen dynamics of the forest floor (2006, background): “In the field, application of nitrogen has variable effects on litter decomposition (Neff et al., 2002; Micks et al., 2004), and on enzymic activities of decomposers, including polyphenol oxidation and polysaccharide hydrolysis (Sinsabaugh et al.”
Cheaters, diffusion and nutrients constrain decomposition by microbial enzymes in spatially structured environments (2005, background): “Melillo et al. 1982) and EnzModel confirms that N could limit decomposition through constraints on degradative enzyme synthesis [but see Berg & Matzner (1997) and Neff et al. (2002) ].”
Microbial enzyme activities in leaf litter, humus and mineral soil layers of European forests (2004, neutral): “SOM with decadal turnover times (Hagedorn et al., 2001; Neff et al., 2002).”
Ecosystem carbon storage in arctic tundra reduced by long-term nutrient fertilization (2004, background): “In ecosystems at lower latitudes, natural and manipulated nutrient concentrations have had a positive, a negative, or no effect on the decomposition of litter and soil organic C (SOC”
