Soil Microbial Community Responses to Multiple Experimental Climate Change Drivers (2009, background): “For example, researchers have found that changes in CO2 do not predictably alter microbial biomass (35, 62).”
Soil microbial activity in a Liquidambar plantation unresponsive to CO2-driven increases in primary production (2003, background): “Increases in root exudation and fine root turnover have been observed in many studies ( Zak et al., 2000 ).”
Mycorrhizal mediation of plant N acquisition and residue decomposition: Impact of mineral N inputs (2006, background): “, 2004), may facilitate residue decomposition by stimulating microbial activity through enhanced labile C availability from the host plant (Zak et al., 2000; Nakano et al., 2001).”
Elevated atmospheric CO2 increases microbial growth rates in soil: results of three CO2 enrichment experiments (2010, background): “…communities – DNA content, total PLFA and diversity estimated based on PLFA analysis – registered no or only a subtle effect of elevated CO2 (Griffiths et al., 1998; Zak et al., 2000b; Ebersberger et al., 2004; Lipson et al., 2006; Denef et al., 2007; Kanerva et al., 2008; Paterson et al., 2008).”
Soil microbial indices as bioindicators of environmental changes in a poplar plantation (2005, background): “Terrestrial ecosystems response to CO2 fertilization is therefore linked to the knowledge of belowground processes and particularly those performed by the microbial pool ( Zak et al., 2000 ).”
Extracellular Enzyme Activity Beneath Temperate Trees Growing Under Elevated Carbon Dioxide and Ozone (2002, background): “…crease), even though microbial respiration generally in- and impair stomatal function (Tjoelker et al., 1995), creases in response to elevated CO2 (Zak et al., 2000b). which can lower the allocation of C to root growth (Scagel After 2 yr of CO2 and O3 enrichment of the atmosphere, and Andersen,…”
Building roots in a changing environment: implications for root longevity (2000, background): “Elevated CO # might increase mycorrhizal colonization (Tingey et al., 2000), reduce root palatability by decreasing N concentration, and cause large changes in the soil biota (Zak et al., 2000).”
Laccases: toward disentangling their diversity and functions in relation to soil organic matter cycling (2010, background): “Lignin mineralization involves two sequential processes: (a) the primary attack and breakdown of aromatic polymers to oligo- or monomers and (b) the complete degradation of these products to CO2, H2O, and minerals (Talbot et al. 2008).”
Elevated CO2 stimulates net accumulations of carbon and nitrogen in land ecosystems: a meta-analysis. (2006, unknown): “Increased C input into soil (Zak et al. 2000) (Fig.”
Assessment of 10 years of CO2 fumigation on soil microbial communities and function in a sweetgum plantation (2009, background): “Fine root turnover may provide a labile pool of easily metabolized C to microbial communities (Zak et al., 2000a).”
Progressive N limitation of plant response to elevated CO2: a microbiological perspective (2006, background): “…activities Because soil microbes are in general C-limited (Smith and Paul 1990), CO2-enhancement of C inputs through either root rhizodeposition or lit- ter can stimulate the growth and/or activities of saprophytes (Diaz et al. 1993; Paterson et al. 1997; Hu et al. 1999; Zak et al. 2000b).”
