“…Such cross-generational plasticity most frequently involves interactions between mothers and their offspring, and has also been demonstrated in relation to temperature (maternal effects; Mousseau & Fox 1998, AmarilloSuárez & Fox 2006, Steigenga & Fischer 2007, Kjaersgaard et al 2010, this Special, Scharf et al 2010. Finally, spatial and/or temporal temperature variation may, over the long term, induce evolutionary (genetic) adaptation.…”

Variable thermal environments experienced by most organisms warrant mechanisms to adjust the expression of phenotypic values to environmental needs. Here we explored short-(mainly developmental plasticity) and long-term effects (genetic differentiation across altitudes) of temperature variation using copper butterflies as model organisms. Lower compared to higher developmental temperatures yielded predictable variation by increasing development time, body size, total food consumption, the efficiency of converting digested food into body matter, and cold stress resistance, but decreasing daily food consumption, assimilation efficiency, body fat and protein content, weight loss at metamorphosis, the proportion of directly developing individuals, pupal melanisation and heat stress resistance. While variation in temperature stress resistance and developmental pathways is likely to reflect adaptive phenotypic plasticity, the reasons underlying variation in other traits are less clear. High-altitude populations showed increased development time, egg size, flight performance, wing and pupal melanisation and cold stress resistance, but decreased body fat content and heat stress resistance, compared to low-altitude populations. The differences seem to be mainly caused by thermal adaptation and seasonal time constraints. Cold stress resistance was related to variation at the phosphoglucose isomerase locus, and variation in heat stress resistance showed patterns similar to variation in the expression of stress-inducible heat shock proteins. High-altitude populations showed clearly reduced plasticity in heat stress tolerance, which may pose a substantial problem, given the rising temperatures at a global scale.

“…Larvae were kept in gauze sleeves and fed on maize in groups of approximately 20 individuals per plant. This density is relatively low compared to what has been used in other studies (e.g., Stelgenga and Fischer 2007;Bauerfeind and Fischer 2009), as the aim was to rear the larvae at this stage under optimal nonstressful conditions. The small sleeve cages also ensured that larval food was never limited, and the sleeves were checked daily and fresh plants were provided to ensure ad lib.…”

The experience of environmental stress during development can substantially affect an organism's life history. These effects are often mainly negative, but a growing number of studies suggest that under certain environmental conditions early experience of such stress may yield individuals that are less sensitive to environmental stress later on in life. We used the butterfly Bicyclus anynana to study the effects of limited larval and adult food and forced flight on individual performance measured as reproduction and adult life span. Larvae exposed to food stress showed longer development and produced smaller adults. Thus, they were not able to fully compensate for the food deprivation during development. Females that experienced food stress during development did not increase tolerance for adult food limitation. However, females exposed to food stress during development coped better with forced flight compared with the control group. The apparent absence of costs of flight in poor-quality females may be a by-product of an altered body allocation, as females experiencing both food stress treatments had increased thorax ratios, compared with controls, and increased flight performances. The results reveal an important plasticity component to variation in flight performance and suggest that the cost of flight depends on an individual's internal condition.

Moreover, it is increasingly clear that the different timescales of thermal exposure may result in different underlying responses and mechanisms (e.g.…”

The influence of thermal history on temperature-dependent flight performance was investigated in an invasive agricultural pest insect, Ceratitis capitata (Diptera: Tephritidae). Flies were exposed to one of four developmental acclimation temperatures (T acc : 15, 20, 25, 30°C) during their pupal stage and tested at these temperatures (T test ) as adults using a full-factorial study design. Major factors influencing flight performance included sex, body mass, T test and the interaction between T test and T acc . Successful flight performance increased with increasing T test across all acclimation groups (from 10% at 15°C to 77% at 30°C). Although T acc did not affect flight performance independently, it did have a significant interaction effect with T test . Multiple comparisons showed that flies which had been acclimated to 15°C and 20°C performed better than those acclimated to 25°C and 30°C when tested at cold temperatures, but warm-acclimated flies did not outperform cold-acclimated flies at warmer temperatures. This provides partial support for the 'colder is better' hypothesis. To explain these results, several flight-related traits were examined to determine whether T acc influenced flight performance as a consequence of changes in body or wing morphology, whole-animal metabolic rate or cytochrome c oxidase enzyme activity. Although significant effects of T acc could be detected in several of the traits examined, with an emphasis on sex-related differences, increased flight performance could not be explained solely on the basis of changes in any of these traits. Overall, these results are important for understanding dispersal physiology despite the fact that the mechanisms of acclimation-related changes in flight performance remain unresolved.
