We explored the extent to which a phenotypic trait (walking speed) of Drosophila melanogaster is influenced by population, developmental temperature, adult temperature, and age. Our goals were to estimate the importance of these factors and to test the beneficial acclimation hypothesis. We measured speed of flies from two populations (the Congo and France) that developed at different temperatures (18, 25, and 29 C) and were tested at different temperatures (18, 25, and 29°C) and ages (2, 7, 13… Expand
Reproductive fitness of Drosophila is maximised by optimal developmental temperature
TLDR
The results show that flies from both populations raised at an intermediate developmental temperature have comparable or higher early fecundity and fertility at all tested adulthood temperatures, while lower (17°C) or higher developmental temperatures did not entail any advantage under the tested thermal regimes. Expand
Temperature‐specific acclimation effects on adult locomotor performance of inbred and crossbred Drosophila melanogaster
TLDR
Investigation of whether inbreeding affects the capacity to reach a food source in male Drosophila melanogaster Meigen 1830 reared at 20, 25 or 30 °C suggests complex traits such as locomotor performance in a maze are highly informative in the evaluation and detection of inbreeding depression under different thermal conditions. Expand
The effect of developmental temperature fluctuation on wing traits and stressed locomotor performance in Drosophila melanogaster, and its dependence on heterozygosity
TLDR
Performance mostly declined if the flies were reared under the fluctuating temperature regime versus the constant temperature regime with the same mean, and crossbred genotypes compared across constant temperatures also showed greater plasticity in wing aspect. Expand
Investigating thermal acclimation effects before and after a Cold shock in Drosophila melanogaster using behavioural assays
TLDR
The results provide support for both the beneficial acclimation hypothesis and the optimal developmental temperature hypothesis, but the results are highly context dependent and change with the temperature experienced by the individual during its lifetime. Expand
COMPLEX PATTERNS OF PHENOTYPIC PLASTICITY: INTERACTIVE EFFECTS OF TEMPERATURE DURING REARING AND OVIPOSITION
TLDR
The higher elevation population was larger and matured sooner than the low-elevation population when raised at the lower temperature, but the reverse was true at the higher temperature suggesting that these populations have adapted to local temperature. Expand
Thermal acclimation of swimming performance in newt larvae: the influence of diel temperature fluctuations during embryogenesis
TLDR
Evidence is provided that diel temperature fluctuations induce acclimation of thermal dependence of locomotor performance in ectotherms experiencing diel cycles in environmental temperatures, and this plastic response may act as an important pacemaker in the evolution of thermal sensitivity. Expand
Laboratory selection for increased longevity in Drosophila melanogaster reduces field performance
TLDR
Control lines were better able to locate a resource compared to longevity selected lines of the same age, suggesting that longevity comes at a cost in early life field fitness, supporting the antagonistic pleiotropy theory of ageing. Expand
The relative contributions of developmental plasticity and adult acclimation to physiological variation in the tsetse fly, Glossina pallidipes (Diptera, Glossinidae)
TLDR
This study demonstrates that the stage at which acclimation takes place has significant, though often different, effects on several adult physiological traits in G. pallidipes, and therefore that it is not only important to consider the form of plasticity but also the direction of the response and its significance from a life-history perspective. Expand
The influence of developmental diet on reproduction and metabolism in Drosophila
TLDR
The findings suggest that the observed differences in the adult physiology induced by early-life diet likely result from inevitable and general effects of nutrition on the development of reproductive and metabolic organs, rather than from adaptive mechanisms. Expand
Transgenerational and within‐generation plasticity shape thermal performance curves
TLDR
It is found that both, environmental thermal variability and high temperature experienced during early ontogeny shaped the fruit fly TPC sensitivity, and since TPC parameters are not fixed, cautiousness is suggested when using TPCs to predict the impact of climate change on natural populations.

THE EFFECT OF TEMPERATURE ON BODY SIZE AND FECUNDITY IN FEMALE DROSOPHILA MELANOGASTER: EVIDENCE FOR ADAPTIVE PLASTICITY
TLDR
It is found that female D. melanogaster reared to adulthood at 18°C versus 25°C showed a 12% increase in dry weight, which breaks the usual positive correlation between body size and fecundity, and the finding that the temperature treatments resulted in a trade‐off between early fecundities and longevity, a trade-off that parallels the known genetic correlation.

WITHIN‐ AND BETWEEN‐GENERATION EFFECTS OF TEMPERATURE ON THE MORPHOLOGY AND PHYSIOLOGY OF DROSOPHILA MELANOGASTER
TLDR
The existence of significant within‐ and between‐generation effects suggests that comparative studies need to standardize thermal environments for at least two generations, that attempts to estimate “field” heritabilities may be unreliable for some traits, and that predictions of short‐term evolutionary responses to selection will be difficult. Expand
Thermal Sensitivity of Drosophila melanogaster: Evolutionary Responses of Adults and Eggs to Laboratory Natural Selection at Different Temperatures
TLDR
Fitness at moderately high temperatures is genetically coupled with tolerance of extreme high ( but not of low) temperature, and long‐term natural selection has led to divergence in thermal sensitivity of some (but not of all) traits and may have had more of an impact on adults than on eggs. Expand
Within- and between-generation effects of temperature on early fecundity of Drosophila melanogaster
TLDR
It is demonstrated that early fecundity is extraordinarily sensitive to laying temperature, but is relatively well buffered against developmental and cross-generational effects (maximum effect only 7 per cent, for sire temperature). Expand

TLDR
These experiments demonstrate that developmental temperatures, both within and between generations, influence territorial success in male flies. Expand

TLDR
It is shown that the general, all purpose method of polynomial adjustment provides a convenient way for the description of the norms and shows that the shapes of the reaction norms are genetically variable and suggest adaptive responses to the environment. Expand

TLDR
Results show that Gpdh can be considered a minor polygene affecting quantitative variation in the power output during flight and that genotype-by-environment interaction is an important component of that effect. Expand

TLDR
Chill coma and its recovery seem to imply a modification of the nervous system, analogous in several aspects to what is observed with usual anaesthetics such as CO 2 . Expand

TLDR
Estimations of flight muscle mechanical power output yields a peak performance of 110 W kg−1 muscle tissue for short-burst flight that was measured at an ambient temperature of 30 °C, similar to those that were published for flight under tethered flight conditions. Expand
