Influence of Environmental Variability on Root Dynamics in Northern Forests (2009, background): “…net primary production (Pregitzer et al., 1995; King et al., 1999b; Allen et al., 2000; Matamala and Schlesinger, 2000; Pregitzer et al., 2000a; Pregitzer et al., 2000b; Tingey et al., 2000; King et al., 2001; Pregitzer, 2002; Pendall et al., 2004; Wan et al., 2004; Heath et al., 2005; King et…”
The response of two Glomus mycorrhizal fungi and a fine endophyte to elevated atmospheric CO2, soil warming and drought (2004, background): “If, for example, mycorrhizal hyphae respond in a similar manner to eCO2 and soil temperature as do fine roots (i.e. by an increase in turnover) (Pregitzer et al., 2000; Tingey et al., 2000; Edwards et al., 2004), then clearly the amount of carbon entering the soil could be substantially increased.”
The likely impact of elevated [CO2], nitrogen deposition, increased temperature and management on carbon sequestration in temperate and boreal forest ecosystems: a literature review. (2007, background): “, 2005), although this does not appear to be the case universally (Tingey et al., 2000).”
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).”
Soil CO2 efflux in a boreal pine forest under atmospheric CO2 enrichment and air warming (2004, background): “Furthermore, the biomass and net CO2 assimilation of woody plants increase under conditions of elevated atmospheric CO2 (Curtis & Wang, 1998; Saxe et al., 1998), accompanied by increased root growth and consequent carbon inputs to the soil (Matamala & Schlesinger, 2000; Tingey et al., 2000).”
Below‐ground responses of silver birch trees exposed to elevated CO2 and O3 levels during three growing seasons (2005, background): “In most studies, CO2 enrichment has enhanced root growth and mycorrhiza formation or increased mycorrhizal biomass and soil microbial biomass (O’Neill et al., 1987; O’Neill 1994; Ineichen et al., 1995; Paterson et al., 1997; Tingey et al., 2000; Treseder & Allen 2000; Zak et al., 2000; Langley et al”
Global patterns of root turnover for terrestrial ecosystems (2000, background): “Studies with minirhizotrons have shown that a subset of roots in both grasslands and forests is highly dynamic, having a lifespan of days to weeks (Hendrick & Pregitzer, 1997; Gill, 1998; Arnone et al., 2000; Tingey et al., 2000).”
