“…Like the compensatory adjustments of metabolic rate that occur during temperature acclimation, the protective effects of RCH, and therefore the underlying physiological mechanisms, also require time to develop Coulson and Bale, 1990). We hypothesized that the metabolic rate would be elevated during RCH if energy were required for this response.…”

“…Previously, investigators hypothesized that RCH allows an insect's overall cold tolerance to track rapid environmental temperature shifts, especially during the spring and autumn months when diurnal temperature extremes are most dramatic Coulson and Bale, 1990;Kelty and Lee, 1999). However, Kelty and Lee (2001) showed that cooling D. melanogaster from 23°C to 16°C induces an RCH response that increases sub-zero survival.…”

“…Adjustments in metabolic rate may provide clues to the underlying mechanisms responsible for RCH. Coulson and Bale (1990) speculated that compensatory shifts in the metabolic rate might account, at least in part, for the observed effects of RCH. If so, the time required to reach a stable metabolic rate at a lower temperature after transfer from the rearing temperature should be less in RCH flies since the compensatory changes are already in place.…”

SUMMARY The primary objectives of this study were to determine (1) whether rapid cold-hardening (RCH) preserves reproductive behaviors during modest cooling,(2) whether increased mating success at a lower temperature comes at the cost of decreased performance at a higher temperature and (3) whether RCH is associated with an elevated metabolic rate. Drosophila melanogaster(Diptera: Drosphilidae) were rapidly cold-hardened by a 2-h exposure to 16°C prior to experiments. A temperature decrease of only 7°C(23°C to 16°C) prevented half (11/22) of the control pairs of D. melanogaster from engaging in any courtship activity. By contrast, most RCH pairs courted (17/20). Additionally, the 7°C transfer prevented mating in every pair of control flies, whereas more than half (11/20) of the RCH pairs mated. There was no evidence of impaired courtship or mating performance when RCH pairs were tested at 23°C. Finally, RCH is apparently not an energy-demanding process because no increase in the metabolic rate was detected during its induction. Overall, these data demonstrate that RCH serves to constantly fine-tune an insect's physiological state to match slight changes in environmental temperature. Furthermore, the RCH response is not restricted to cryoprotection and survival in the cold but also preserves more subtle behaviors, such as courtship, at moderate to high temperatures throughout the year.

“…The ability of insects to rapidly cold-harden was first reported by Lee et al (1987). Many studies have since characterised the advantages and limitations of this response in a range of species groups (Broufas and Koveos, 2001;Coulson and Bale, 1990;Czajka and Lee, 1990;Larsen and Lee, 1994;Powell and Bale, 2004). Most of these studies have regarded rapid coldhardening and seasonal (winter) acclimation as separate processes.…”

“…Although summer-acclimated insects may have a greater potential to demonstrate a RCH response, in the Northern Hemisphere, the ecological importance of this ability is more associated with low-temperature survival, either in autumn and spring, when seasonal acclimation is incomplete or receding, or during periods with rapidly fluctuating temperatures (Lee et al, 1987;Coulson and Bale, 1990;Kelty and Lee, 1999). In other words, in natural environments, the conditions under which rapid cold-hardening might be induced are likely to be part of a trend of decreasing, or generally low, temperatures that would have already triggered the start of seasonal cold acclimation.…”

SUMMARY In contrast to previous studies of rapid cold-hardening (RCH), which have investigated the responses of insects maintained under `summer conditions'(20° to 25°C), this study focuses on the ability of low-temperature acclimated insects to undergo RCH. When the grain aphid Sitobion avenae Fabricus was low-temperature acclimated by rearing for three generations at 10°C, the discriminating temperatures (temperature that results in approximately 20% survival after direct transfer from the rearing temperature to a sub-zero temperature for a period of 3 h), of first instar nymphs and adult aphids were –11.5° and –12°C,respectively. Maximum rapid cold-hardening was induced by cooling aphids at 0°C for 2 h (nymphs) or 30 min (adults), resulting in survival at the respective discriminating temperatures increasing from 26% to 96% (nymphs) and 22% to 70% (adults). Cooling from 10° to 0°C at 1°, 0.1° and 0.05°C min-1 significantly increased survival of nymphs at the discriminating temperature, but not of adults. There were no `ecological costs' associated with rapid cold-hardening at 0°C, or with exposure of rapidly cold-hardened aphids to the discriminating temperatures; fecundity and longevity, in both nymphs and adults were either similar to control aphids or significantly increased. The study demonstrates that rapid cold-hardening ability is retained in aphids that have already undergone cold-acclimation, as would be the case in overwintering aphids. Both rapid cold-hardening and subsequent exposure at previously lethal temperatures can enhance fitness in surviving individuals.

Understanding how thermal selection affects phenotypic distributions across different time scales will allow us to predict the effect of climate change on the fitness of ectotherms. We tested how seasonal temperature variation affects basal levels of cold tolerance and two types of phenotypic plasticity in Drosophila melanogaster. Developmental acclimation occurs as developmental stages of an organism are exposed to seasonal changes in temperature and its effect is irreversible, while reversible short-term acclimation occurs daily in response to diurnal changes in temperature. We collected wild flies from a temperate population across seasons and measured two cold tolerance metrics (chill-coma recovery and cold stress survival) and their responses to developmental and short-term acclimation. Chill-coma recovery responded to seasonal shifts in temperature, and phenotypic plasticity following both short-term and developmental acclimation improved cold tolerance. This improvement indicated that both types of plasticity are adaptive, and that plasticity can compensate for genetic variation in basal cold tolerance during warmer parts of the season when flies tend to be less cold tolerant. We also observed a significantly stronger trade-off between basal cold tolerance and short-term acclimation during warmer months. For the longer-term developmental acclimation, a trade-off persisted regardless of season. A relationship between the two types of plasticity may provide additional insight into why some measures of thermal tolerance are more sensitive to seasonal variation than others.
