“…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.

“…Acclimation results in R dark being of similar magnitude in plants grown at different temperatures when measured at their respective growth temperatures (Larigauderie and Körner, 1995;Atkin and Tjoelker, 2003) and also results in R dark at 25 • C, increasing upon cold acclimation and declining upon acclimation to warmer temperature . Growth temperature-dependent changes in R dark at a standard temperature can occur over periods of 1-3 days (Atkin et al, 2000;Bolstad et al, 2003;Lee et al, 2005;Zaragoza-Castells et al, 2007;Armstrong et al, 2008). A data synthesis of global patterns in R dark showed that geographic variation in R dark at growth temperature from the tropics to the tundra is much smaller than would be expected on the basis of enzyme kinetics.…”

Thermal acclimation of leaf photosynthetic traits in an evergreen woodland, consistent with the coordination hypothesis

et al. 2018

Abstract. Ecosystem models commonly assume that key photosynthetic traits, such as carboxylation capacity measured at a standard temperature, are constant in time. The temperature responses of modelled photosynthetic or respiratory rates then depend entirely on enzyme kinetics. Optimality considerations, however, suggest this assumption may be incorrect. The "coordination hypothesis" (that Rubisco-and electron-transport-limited rates of photosynthesis are co-limiting under typical daytime conditions) predicts, instead, that carboxylation (V cmax ) capacity should acclimate so that it increases somewhat with growth temperature but less steeply than its instantaneous response, implying that V cmax when normalized to a standard temperature (e.g. 25 • C) should decline with growth temperature. With additional assumptions, similar predictions can be made for electron-transport capacity (J max ) and mitochondrial respiration in the dark (R dark ). To explore these hypotheses, photosynthetic measurements were carried out on woody species during the warm and the cool seasons in the semi-arid Great Western Woodlands, Australia, under broadly similar light environments. A consistent proportionality between V cmax and J max was found across species. V cmax , J max and R dark increased with temperature in most species, but their values standardized to 25 • C declined. The c i : c a ratio increased slightly with temperature. The leaf N : P ratio was lower in the warm season. The slopes of the relationships between log-transformed V cmax and J max and temperature were close to values predicted by the coordination hypothesis but shallower than those predicted by enzyme kinetics.

Climate change effects on northern Great Lake (USA) forests: A case for preserving diversity

et al. 2014

Abstract. Under business as usual (BAU) management, stresses posed by climate change may exceed the ability of Great Lake forests to adapt. Temperature and precipitation projections in the Great Lakes region are expected to change forest tree species composition and productivity. It is unknown how a change in productivity and/or tree species diversity due to climate change will affect the relationship between diversity and productivity. We assessed how forests in two landscapes (i.e., northern lower Michigan and northeastern Minnesota, USA) would respond to climate change and explored the diversityproductivity relationship under climate change. In addition, we explored how tree species diversity varied across landscapes by soil type, climate, and management. We used a spatially dynamic forest ecosystem model, LANDIS-II, to simulate BAU forest management under three climate scenarios (current climate, low emissions, and high emissions) in each landscape. We found a positive relationship between diversity and productivity only under a high emissions future as productivity declined. Within landscapes, climate change simulations resulted in the highest diversity in the coolest climate regions and lowest diversity in the warmest climate region in Minnesota and Michigan, respectively. Simulated productivity declined in both landscapes under the high emissions climate scenario as species such as balsam fir (Abies balsamea) declined in abundance. In the Great Lakes region, a high emissions future may decrease forest productivity creating a more positive relationship between diversity and productivity. Maintaining a diversity of tree species may become increasingly important to maintain the adaptive capacity of forests.
