Dynamics of fine root carbon in Amazonian tropical ecosystems and the contribution of roots to soil respiration (2006, unknown): “However, estimates of ﬁne root production made with observations of root growth and death (for example through minirhizotrons) suggest that at least some of the ﬁne root pool is much more dynamic (Pregitzer, 2002; Tierney & Fahey, 2002).”
Endogenous and exogenous controls of root life span, mortality and nitrogen flux in a longleaf pine forest: root branch order predominates (2008, background): “…to separate roots with different turnover rates (Gill & Jackson 2000; Pregitzer et al. 2002), and there is evidence linking root life span to diameter (Wells & Eissenstat 2001; Tierney & Fahey 2002; Matamala et al. 2003), the choice of diameter classes is inherently arbitrary (Pregitzer 2002).”
Use of stored carbon reserves in growth of temperate tree roots and leaf buds: analyses using radiocarbon measurements and modeling (2009, methodology): “Past studies have used hemispheric 14C atmospheric records (i.e., Burchuladze et al., 1989; Levin & Kromer, 1997, 2004; Levin & Hesshaimer, 2000) as estimates of local atmospheric 14CO2 (Gaudinski et al., 2001; Tierney & Fahey, 2002; Trumbore et al., 2006).”
Soil respiration and soil carbon balance in a northern hardwood forest ecosystem (2005, methodology): “These measurements were conducted in the lower hardwood zone plot adjacent to our minirhizotron site at the HBEF (Tierney and Fahey 2002).”
Fine root architecture, morphology, and biomass of different branch orders of two Chinese temperate tree species (2006, background): “…chemistry (e.g., nitrogen and total nonstructural carbohydrates) and lifespan among fine roots (Wells and Eissenstat 2001; Pregitzer et al. 2002; Tierney and Fahey 2002; Guo et al. 2004), it is clear that roots of different orders are turning over at markedly different rates, and returning…”
Dynamics of Fine Root, Fungal Rhizomorphs, and Soil Respiration in a Mixed Temperate Forest: Integrating Sensors and Observations (2008, background): “Th e minirhizotron may emphasize the more rapidly cycling 1° roots, while our radiocarbon data tend to refl ect 2° to 4° fi ne roots that persist much longer in the soil, and branching order is important to estimate fi ne root radiocarbon age (Gaudinski et al., 2001; Tierney and Fahey, 2002).”
