Basal rates of soil respiration are correlated with photosynthesis in a mixed temperate forest (2007, background): “When substrate availability limits SR, changes in substrate availability affects the apparent Q10 (Davidson et al., 2006) (apparent Q10 5 Q10 derived from field measurements of SR and temperature).”
Thermal acclimation of organic matter decomposition in an artificial forest soil is related to shifts in microbial community structure (2014, background): “(2013), and supports the established temperature-dependency of soil extracellular enzymes when other factors such as soil moisture and substrate availability remain constant (Davidson et al., 2006; Henry, 2012; Burns et al., 2013).”
Thermal adaptation of soil microbial respiration to elevated temperature. (2008, background): “Dose–response experiments confirmed these amounts were in excess of demand, which avoided the confounding effect of substrate-limitation when assessing the response of enzyme-catalyzed reactions to temperature (Davidson et al. 2006).”
REVIEW: Time lag between photosynthesis and carbon dioxide efflux from soil: a review of mechanisms and controls (2010, background): “However, defining the classical effect of temperature on rates of decomposition processes with the Q10 function has recently been challenged (Davidson et al., 2006; Davidson & Janssens, 2006).”
Stability and dynamics of enzyme activity patterns in the rice rhizosphere: Effects of plant growth and temperature (2017, background): “Such a general reduction in temperature sensitivity (Q10) confirms theoretical predictions (Davidson et al., 2006) and experimental observations at low substrate concentrations (Razavi et al., 2015; Blagodatskaya et al., 2016).”
Effect of temperature on metabolic activity of intact microbial communities: Evidence for altered metabolic pathway activity but not for increased maintenance respiration and reduced carbon use efficiency (2011, background): “…related to microbial energetics: how do increased C inputs and higher temperatures change the balance between ATP production and consumption, and thereby CO2 production, N mineralization, and soil organic matter formation (De Graaff et al., 2006; Hungate et al., 2009; Van Groenigen et al., 2006)?”
A conceptual and practical approach to data quality and analysis procedures for high‐frequency soil respiration measurements (2008, methodology): “SR is influenced by several factors, primarily temperature, soil moisture, root growth and substrate supply ( Davidson, Janssens & Luo 2006; Liu et al . 2006).”
Consistent temperature dependence of respiration across ecosystems contrasting in thermal history (2012, methodology): “…also revealed that the Q10 was a constant function of measurement temperature, in contrast to observations in terrestrial plants (Atkin et al., 2000; Atkin & Tjoelker, 2003) and soils (Davidson & Janssens, 2006; Davidson et al., 2006), and contrary to expectations from the Arrhenius equation.”
Soil respiration in perennial grass and shrub ecosystems: Linking environmental controls with plant and microbial sources on seasonal and diel timescales (2008, background): “Over both timescales, soil respiration is still largely described with empirical models based on site-specific relationships [ Davidson et al. , 2006].”
Whole ecosystem metabolic pulses following precipitation events (2008, background): “the exponential term in Eq. 1). E a A main critique of research examining biological temperature sensitivities has highlighted the dynamic temperature sensitivity of biologic systems (Luo et al . 2001; Clarke & Fraser 2004; Yuste et al . 2004; Davidson, Janssens & Luo 2006 ).”
Investigating biological control over soil carbon temperature sensitivity (2009, background): “Q10 values for soils have shown wide ranges (Davidson et al., 2006).”
Thermal performance curves, phenotypic plasticity, and the time scales of temperature exposure. (2011, background): “A number of models, largely generated by plant biologists, take this effect into account (reviewed by Atkin and Tjoelker 2003; Davidson et al. 2006; Kruse et al. 2011).”
Response of mycorrhizal, rhizosphere and soil basal respiration to temperature and photosynthesis in a barley field (2007, background): “water status and assimilate supply (Högberg et al., 2001; Davidson and Janssens, 2006; Davidson et al., 2006).”
Bringing the Kok effect to light: A review on the integration of daytime respiration and net ecosystem exchange (2013, background): “…Q10 values are nonlinear, and using fixed values could lead to over- or under-estimation of ER over longer time scales (Tjoelker et al. 2001, Davidson et al. 2006, Xu et al. 2007), and temperatures experienced during the day are warmer than experienced at nighttime and represent a portion…”
