“…Given that previous physiological research and our own correlations described above suggest that only some mechanisms are shared between long-term and short-term acclimation (10,19), we expect that the degree of genetic overlap between RCH and DACC responses will be small or undetectable. We found no SNPs overlapping among RCH at 25°C (61 SNPs), RCH after DACC at 18°C (103 SNPs), and DACC (66 SNPs, P < 10…”

“…The longer-term DACC response may induce a larger degree of change in any mechanisms that overlap between DACC and RCH and also may induce additional mechanisms unique to DACC (10,19,26). There is substantial variation in the timing and number of extreme swings in temperature, such as those associated with fastmoving cold fronts, from year to year.…”

“…Acclimation responses, a form of adaptive phenotypic plasticity, are particularly important for mitigating thermal stress in ectotherms. Although studies of plasticity often consider responses that occur over moderately long time scales-termed "developmental acclimation" (DACC)-acclimation responses can occur over both longer and very short time scales (7)(8)(9)(10). Rapid cold hardening (RCH) is one such short-time-scale plastic response wherein ectotherms exposed to mild low temperatures for minutes to hours suffer less from subsequent exposure to lower temperatures (7,8,11,12).…”

“…Despite its ecological importance, the physiological and genetic mechanisms underlying RCH have been challenging to unravel using physiological, transcriptomic, or metabolomic techniques, particularly because the physiological responses are both fast and transient (20)(21)(22)(23)(24)(25). Thus, there is substantial debate about how much the mechanisms of developmental and rapid thermal acclimation overlap (10,14,19,26).…”

Seasonal and daily thermal variation can limit species distributions because of physiological tolerances. Low temperatures are particularly challenging for ectotherms, which use both basal thermotolerance and acclimation, an adaptive plastic response, to mitigate thermal stress. Both basal thermotolerance and acclimation are thought to be important for local adaptation and persistence in the face of climate change. However, the evolutionary independence of basal and plastic tolerances remains unclear. Acclimation can occur over longer (seasonal) or shorter (hours to days) time scales, and the degree of mechanistic overlap is unresolved. Using a midlatitude population of Drosophila melanogaster, we show substantial heritable variation in both short-and long-term acclimation. Rapid cold hardening (short-term plasticity) and developmental acclimation (long-term plasticity) are positively correlated, suggesting shared mechanisms. However, there are independent components of these traits, because developmentally acclimated flies respond positively to short-term acclimation. A strong negative correlation between basal cold tolerance and developmental acclimation suggests that basal cold tolerance may constrain developmental acclimation, whereas a weaker negative correlation between basal cold tolerance and short-term acclimation suggests less constraint. Using genome-wide association mapping, we show the genetic architecture of rapid cold hardening and developmental acclimation responses are nonoverlapping at the SNP and corresponding gene level. However, genes associated with each trait share functional similarities, including genes involved in apoptosis and autophagy, cytoskeletal and membrane structural components, and ion binding and transport. These results indicate substantial opportunity for short-term and long-term acclimation responses to evolve separately from each other and for short-term acclimation to evolve separately from basal thermotolerance.

“…In particular, cold may be divided into acute (short, intense) and chronic (longer and less intense) exposures, which seem to result in different forms of injury -through membrane phase transition in acute, intense exposures, and through ion equilibration in more chronic exposures (although we note that phase transition would also result in ion equilibration). Most RCH investigations have involved acute cold exposure, although Shintani and Ishikawa (2007) reported a reduced RCH effect in Psacothea hilaris eggs exposed to a relatively mild temperature (which necessitates a longer exposure time), compared to a more acute exposure to a lower temperature. This implies that RCH may not impart increased tolerance to chronic cold exposure, although this hypothesis has not been explicitly tested.…”

We quantified the variation and plasticity in cold tolerance among four larval stages of four laboratory strains of Drosophila melanogaster in response to both acute (<2 hours of cold exposure) and chronic (∼7 hours of cold exposure) cold exposure. We observed significant differences in basal cold tolerance between the strains and among larval stages. Early larval instars were generally more tolerant of acute cold exposures than 3 rd instar larvae. However, wandering larvae were more tolerant of chronic cold exposures than the other stages. Early stages also displayed a more pronounced rapid cold-hardening response than the later stages. Heat pre-treatment did not confer a significant increase in cold tolerance to any of the strains at any stage, pointing to different mechanisms being involved in resolving heat-and cold-elicited damage. However, when heat pre-treatment was combined with rapid cold-hardening as sequential pre-treatments, both positive (heat first) and negative (heat second) effects on cold tolerance were observed. We discuss possible mechanisms underlying coldhardening and the effects of acute and chronic cold exposures.
