“…However, many experiments that have explicitly tested for beneficial plasticity or acclimation have rejected this hypothesis (Blanckenhorn, 2000;Gibbs et al, 1998;Gibert et al, 2001;Huey et al, 1995;Leroi et al, 1994;Woods, 1999;Woods and Harrison, 2001;Zamudio et al, 1995) or have had mixed results (Bennett and Lenski, 1997;Carter and Wilson, 2006;Stillwell and Fox, 2005). Together these studies suggest that alternative hypotheses, such as "colder/hotter is better," or "optimal developmental temperature" may be evolutionarily more important than beneficial plasticity and acclimation (Huey et al, 1999).…”

“…A large number of recent studies have rejected beneficial plasticity and acclimation (Blanckenhorn, 2000;Gibbs et al, 1998;Gibert et al, 2001;Huey et al, 1995;Leroi et al, 1994;Woods, 1999;Woods and Harrison, 2001;Zamudio et al, 1995), suggesting that these mechanisms are not evolutionarily significant ways for organisms to compensate for their environment. However, most of these studies have only tested performance at the organism's specific developmental temperature, addressing the question, 'do organisms perform better under the conditions that they are reared?'…”

SUMMARYWe use a factorial experimental design to test whether rearing at colder temperatures shifts the lower thermal envelope for flight of Drosophila melanogaster Meigen to colder temperatures. D. melanogaster that developed in colder temperatures (15°C) had a significant flight advantage in cold air compared to flies that developed in warmer temperatures (28°C). At 14°C, cold-reared flies failed to perform a take-off flight ~47% of the time whereas warm-reared flies failed ~94% of the time. At 18°C, cold-and warmreared flies performed equally well. We also compared several traits in cold-and warm-developing flies to determine if colddeveloping flies had better flight performance at cold temperatures due to changes in body mass, wing length, wing loading, relative flight muscle mass or wing-beat frequency. The improved ability to fly at low temperatures was associated with a dramatic increase in wing area and an increase in wing length (after controlling for wing area). Flies that developed at 15°C had ~25% more wing area than similarly sized flies that developed at 28°C. Cold-reared flies had slower wing-beat frequencies than similarly sized flies from warmer developmental environments, whereas other traits did not vary with developmental temperature. These results demonstrate that developmental plasticity in wing dimensions contributes to the improved flight performance of D. melanogaster at cold temperatures, and ultimately, may help D. melanogaster live in a wide range of thermal environments.

“…The 1-or 3-day transient exposures are equivalent to typical weather front durations (Allen et al, 1996;Bosart et al, 1973;Robb and Forbes, 2006). We selected transient temperatures of 18°C and 29°C because these are displaced from the optimal temperature (~25°C) of these flies (Cohet and David, 1978;Huey et al, 1995;Siddiqui and Barlow, 1972), but are not extreme (David et al, 2005). We also maintained some flies at constant temperatures (18°C, 25°C or 29°C) so we could compare the effects of chronic versus transient temperature exposures.…”

“…For example, fecundity increases gradually with temperature to ~25°C and then decreases rapidly at temperatures above 28° to 30°C (David and Clavel, 1969;Huey et al, 1995;McKenzie, 1975;Schnebel and Grossfield, 1986;Siddiqui and Barlow, 1972).…”

SUMMARY The physiological and life history consequences of chronic temperatures are well studied in ectotherms. However, little is known about the consequences of short-term exposure to unusually high or low temperatures, as would occur during a weather front. What are the immediate life-history effects of such thermal transients? Can ectotherms recover quickly or do they suffer carry-over effects that persist after weather returns to normal? We measured the impact of thermal transients on egg and progeny production of Drosophila melanogaster Meigen from Washington State. We reared flies at 25°C and then transferred 3- to 5-day old adults to one of three transient treatments (1 or 3 days at 18°C, 1 day at 29°C) before returning them to 25°C. We monitored daily egg production and egg-to-adult viability before (as a control), during, and after the transient as well as fecundity and viability of flies held at constant 18°, 25° and 29°C. This population appears particularly heat tolerant as neither constant nor transient exposure to 29°C (usually a stressful temperature for this species) affected female fecundity or the viability of her progeny. However, a 1- or 3-day exposure to 18°C reduced female fecundity by 75–90% relative to controls, and eggs laid during the 3-day exposure had greatly reduced viability. When returned to 25°C after transient exposure to 18°C, females immediately matched the fecundity and viability of females maintained constantly at 25°C. Therefore, these flies do not suffer negative carry-over effects from these moderate thermal transients. Surprisingly, fitness (intrinsic rate of population growth) was not depressed by transient temperature exposure. However, the severity and especially the timing of the transient will probably determine the likelihood of carry-over effects as well as its effect on fitness.

“…Thus, poikilothermic animals in expanding populations are expected to favour fast development and early‐age reproduction, both of which are positively influenced by ambient temperature (Taylor 1981; Huey et al . 1995; Dillon, Cahn & Huey 2007), in order to maximize their intrinsic rate of increase (Huey & Berrigan 2001). …”

Cold‐seeking behaviour mitigates reproductive losses from fungal infection in Drosophila

Summary Animals must tailor their life‐history strategies to suit the prevailing conditions and respond to hazards in the environment. Animals with lethal infections are faced with a difficult choice: to allocate more resources to reproduction and suffer higher mortality or to reduce reproduction with the expectation of enhanced immunity and late‐age reproduction. However, the strategies employed to mediate shifts in life‐history traits are largely unknown.Here, we investigate the temperature preference of the fruit fly, Drosophila melanogaster, during infection with the fungal pathogen, Metarhizium robertsii, and the consequence of temperature preference on life‐history traits.We have measured the temperature preference of fruit flies under different pathogen conditions. We conducted multiple fitness assays of the host and the pathogen under different thermal conditions. From these data, we estimated standard measures of fitness and used age‐specific methodologies to test for the fitness trade‐offs that are thought to underlie differences in life‐history strategy.We found that fungus‐infected fruit flies seek out cooler temperatures, which facilitates an adaptive shift in their life‐history strategy. The colder temperatures preferred by infected animals were detrimental to the pathogen because it increased resistance to infection. But, it did not provide net benefits that were specific to infected animals, as cooler temperatures increased lifetime reproductive success and survival whether or not the animals were infected. Instead, we find that cold‐seeking benefits infected animals by increasing their late‐age reproductive output, at a cost to their early‐age reproductive output. In contrast, naive control flies prefer warmer temperatures that optimize early‐age reproductive, at a cost to reproductive output at late ages.These findings show that infected animals exhibit fundamentally different reproductive strategies than their healthy counterparts. Temperature preference can facilitate shifts in strategy, but not without inevitable trade‐offs.
