“…Growth-temperature effects on Q 10 also appear to differ between plants exposed to a new thermal regime for several days and leaves and roots that develop under contrasting temperatures. Covey-Crump et al (2002) found that the Q 10 (between 15-23 • C) of Plantago lanceolata root R was greater at low measurement temperatures in plants exposed to 15 • C for 7 d than in plants kept at 23 • C. Similarly, Rook (1969) found that the Q 10 (between 15-30 • C) of leaf R in Pinus radiata seedlings grown at 33 / 28 • C increased following a 2-d exposure to 15 / 10 • C (rates of R measured at 15-30 • C increased significantly, whereas there was no change in R measured at 8 • C). Conversely, shifting of 15 / 10 • C grown plants to 33 / 28 • C resulted in the Q 10 decreasing within 2 d (again, no change in R at 8 • C was observed).…”

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.

“…Acclimation may occur within a few days of a temperature change (Rook 1969;Billings et al 1971;Atkin et al 2000;Bolstad et al 2003;Lee et al 2005;Slot et al 2014a), but longer exposure to a new temperature may result in a greater degree of homeostasis (Smith and Hadley 1974). Longer exposure enables the plant to make a more complete thermal adjustment-for example, through changes in mitochondrial size and density in leaves (Armstrong et al 2006).…”

of origin and growth form, but respiration was not completely homeostatic across temperatures in the majority of cases. Leaves that developed at a new temperature had a greater capacity for acclimation than those transferred to a new temperature. We conclude that leaf respiration of most terrestrial plants can acclimate to gradual warming, potentially reducing the magnitude of the positive feedback between climate and the carbon cycle in a warming world. More empirical data are, however, needed to improve our understanding of interspecific variation in thermal acclimation capacity, and to better predict patterns in respiratory carbon fluxes both within and across biomes in the face of ongoing global warming. Keywords Climate change · Global patterns · Metaanalysis · Plant ecophysiology · Warming IntroductionClimate warming is predicted to increase the release of carbon dioxide (CO 2 ) from the terrestrial biosphere into the atmosphere, thus triggering a positive climate-terrestrial carbon feedback that accelerates warming (Cox et al. 2000;Luo 2007). However, plant respiration (non-photorespiratory mitochondrial CO 2 release) may be downregulated in response to warming of temperature regimes over days to months, and such acclimation may reduce the potential decline in net primary productivity (NPP) (King et al. 2006;Smith and Dukes 2013;Slot et al. 2014a). High and mid-latitude ecosystems experience more rapid, and greater degrees of warming than the tropics (Stocker et al. 2013), and temperature effects on plant and ecosystem functions have been studied more extensively in temperate and boreal ecosystems than in the tropics. Although tropical regions Abstract Respiration is instrumental for survival and growth of plants, but increasing costs of maintenance processes with warming have the potential to change the balance between photosynthetic carbon uptake and respiratory carbon release from leaves. Climate warming may cause substantial increases of leaf respiratory carbon fluxes, which would further impact the carbon balance of terrestrial vegetation. However, downregulation of respiratory physiology via thermal acclimation may mitigate this impact. We have conducted a meta-analysis with data collected from 43 independent studies to assess quantitatively the thermal acclimation capacity of leaf dark respiration to warming of terrestrial plant species from across the globe. In total, 282 temperature contrasts were included in the meta-analysis, representing 103 species of forbs, graminoids, shrubs, trees and lianas native to arctic, boreal, temperate and tropical ecosystems. Acclimation to warming was found to decrease respiration at a set temperature in the majority of the observations, regardless of the biome Communicated by Rowan Sage.

“…When normalized for plant cover, heated communities did indeed exhibit lower values for both CO 2 fluxes than did unheated communities, which is evidence for acclimation to elevated temperatures. Thermal acclimation of CO 2 fluxes was found in several other studies (Rook, 1969;Larigauderie and Körner, 1995;Loveys et al, 2003;Tjoelker et al, 1998;Atkin et al, 2006), although it did not occur in some studies on root respiration (Sowel and Spomer, 1986;Weger and Guy, 1991;Zogg et al, 1996;Burton and Pregitzer, 2003). Unfortunately, we could not partition our measured ecosystem respiratory fluxes into their autotrophic and heterotrophic components and therefore, we cannot state whether thermal acclimation of TER was due to decreased plant respiration, decreased heterotrophic respiration, or both.…”

Vicca (sara.vicca@ua.ac.be) Although photosynthetic and respiratory rates increase with temperature (Larcher, 2003), both processes and their resulting CO 2 fluxes may also acclimate to warming conditions (Rook, 1969;Körner and Larcher, 1988;Bryla et al, 1997Bryla et al, , 2001Atkin et al, 2000aAtkin et al, , 2006Atkin and Tjoelker, 2003;King et al, 2006).

Effects of climate warming and declining species richness in grassland model ecosystems: acclimation of CO<sub>2</sub> fluxes

Abstract.To study the effects of warming and declining species richness on the carbon balance of grassland communities, model ecosystems containing one, three or nine species were exposed to ambient and elevated (ambient +3 • C) air temperature. In this paper, we analyze measured ecosystem CO 2 fluxes to test whether ecosystem photosynthesis and respiration had acclimated to warming after 28 months of continuous heating, and whether the degree of acclimation depended on species richness. In order to test whether acclimation occurred, short term temperature response curves were established for all communities in both treatments. At similar temperatures, lower flux rates in the heated communities as compared to the unheated communities would indicate thermal acclimation. Because plant cover was significantly higher in the heated treatment, we normalized the data for plant cover. Subsequently, down-regulation of both photosynthesis and respiration was observed. Although CO 2 fluxes were larger in communities with higher species richness, species richness did not affect the degree of acclimation to warming. These results imply that models need to take thermal acclimation into account to simulate photosynthesis and respiration in a warmer world.
