“…Similarly, there is evidence that within species, genotypes from cold habitats can exhibit inherently faster leaf R dark than genotypes from warmer habitats (Mooney, 1963;Oleksyn et al, 1998). However, the pattern (both among and within species) is far from consistent (Chapin & Oechel, 1983;Atkin & Day, 1990;Collier, 1996).…”

SummaryLeaf dark respiration (R dark ) is an important yet poorly quantified component of the global carbon cycle. Given this, we analyzed a new global database of R dark and associated leaf traits. Data for 899 species were compiled from 100 sites (from the Arctic to the tropics). Several woody and nonwoody plant functional types (PFTs) were represented. Mixed-effects models were used to disentangle sources of variation in R dark .Area-based R dark at the prevailing average daily growth temperature (T) of each site increased only twofold from the Arctic to the tropics, despite a 20°C increase in growing T (8-28°C). By contrast, R dark at a standard T (25°C, R dark 25 ) was threefold higher in the Arctic than in the tropics, and twofold higher at arid than at mesic sites. Species and PFTs at cold sites exhibited higher R dark 25 at a given photosynthetic capacity (V cmax 25 ) or leaf nitrogen concentration ([N]) than species at warmer sites. R dark 25 values at any given V cmax 25 or [N] were higher in herbs than in woody plants.The results highlight variation in R dark among species and across global gradients in T and aridity. In addition to their ecological significance, the results provide a framework for improving representation of R dark in terrestrial biosphere models (TBMs) and associated land-surface components of Earth system models (ESMs).

“…Differences in the rate of R at standard measurement temperatures are also commonly exhibited by plants that grew and developed under contrasting temperature regimes (either in the laboratory or in the field) (e.g. Figs 1, 3; Billings and Mooney 1968;Chabot and Billings 1972;Körner and Larcher 1988;Collier and Cummins 1990;Semikhatova et al 1992;Collier 1996;Goldstein et al 1996;Arnone and Körner 1997;Zha et al 2002). In some cases, acclimation is associated with a change in the rate of R primarily at moderate to high measuring temperatures, with little or no change in R at low measuring temperatures (i.e.…”

This paper is part of The Evans Review series, named for Dr Lloyd Evans. The series contains reviews that are critical,state-of-the-art evaluations that aim to advance our understanding, rather than being exhaustive compilations of information, and are written by invitation.Abstract. When predicting the effects of climate change, global carbon circulation models that include a positive feedback effect of climate warming on the carbon cycle often assume that (1) plant respiration increases exponentially with temperature (with a constant Q 10 ) and (2) that there is no acclimation of respiration to long-term changes in temperature. In this review, we show that these two assumptions are incorrect. While Q 10 does not respond systematically to elevated atmospheric CO 2 concentrations, other factors such as temperature, light, and water availability all have the potential to influence the temperature sensitivity of respiratory CO 2 efflux. Roots and leaves can also differ in their Q 10 values, as can upper and lower canopy leaves. The consequences of such variable Q 10 values need to be fully explored in carbon modelling. Here, we consider the extent of variability in the degree of thermal acclimation of respiration, and discuss in detail the biochemical mechanisms underpinning this variability; the response of respiration to long-term changes in temperature is highly dependent on the effect of temperature on plant development, and on interactive effects of temperature and other abiotic factors (e.g. irradiance, drought and nutrient availability). Rather than acclimating to the daily mean temperature, recent studies suggest that other components of the daily temperature regime can be important (e.g. daily minimum and / or night temperature).In some cases, acclimation may simply reflect a passive response to changes in respiratory substrate availability, whereas in others acclimation may be critical in helping plants grow and survive at contrasting temperatures. We also consider the impact of acclimation on the balance between respiration and photosynthesis; although environmental factors such as water availability can alter the balance between these two processes, the available data suggests that temperature-mediated differences in dark leaf respiration are closely linked to concomitant differences in leaf photosynthesis. We conclude by highlighting the need for a greater process-based understanding of thermal acclimation of respiration if we are to successfully predict future ecosystem CO 2 fluxes and potential feedbacks on atmospheric CO 2 concentrations.

“…1996). However, a lack of evidence for differences in R d between plants native to habitats of varying mean annual temperature has also been found (Larigauderie & Körner 1995; Collier 1996; Lavigne 1996; Teskey & Will 1999; Bolstad, Reich & Lee 2003). Our earlier experiments with Quercus alba (largely in laboratory settings) suggested that acclimation is significant, rapid (occurring as soon as 2 days after exposure to changed temperature regimes) and reversible; however, cold‐origin populations were no more plastic in their acclimation response than were warm‐origin populations (Bolstad et al .…”

1.Rates of plant respiration are sensitive to temperature, and modulated by acclimation to prevailing temperature and adaptation to the climate of origin. 2. Our objective was to evaluate the rapidity and magnitude of acclimation of leaf respiration ( R d ) to natural temperature events in field-grown tree seedlings and to assess inter-and intraspecific variation across seasons and years. 3. We measured R d and associated traits of seedlings of three temperate deciduous species, Quercus alba L., Quercus rubra L. and Acer rubrum L., growing in a common garden in St Paul, Minnesota, USA. Seedlings of each species were derived from populations spanning their range from cool/dry (Minnesota/Wisconsin) to warm/moist (North Carolina/Louisiana) regions. 4. Measurements at a common temperature (24 ° C) were made during consecutive cool-and warm-weather systems (differing by 7-10·5 ° C) across two growing seasons. 5. R d rates following the warmest temperatures were 62% lower, on average, than those following cool temperatures. There was little evidence that respiration per se , or its response to temperature, depended on adaptation to climate of origin. 6. Temperature, specific leaf area, and leaf soluble sugar and nitrogen concentrations were important predictors of R d and together explained 77% of the variation across species and populations. 7. To predict forest CO 2 exchange responses to global change accurately, parameters are needed that account for the acclimation of respiration to prevailing temperature.
