The effect of developmental temperature (18°C versus 25°C) on the body size and territorial success of male fruit flies, Drosophila melanogaster, in paired contests was examined. [...] Key Result When tested at ambient temperatures of either 18°C or at 27°C, adult males raised at 25°C were relatively small in size but nevertheless had greater territorial success (control of a food/oviposition resource) than males raised at 18°C.Expand

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. Expand
Increased body size confers greater fitness at lower experimental temperature in male Drosophila melanogaster
TLDR
The results imply that thermal selection for larger adult males is at least in part responsible for the evolution of larger body size at lower temperatures in this species. Expand
Developmental temperature, body size and male mating success in fruit flies, Drosophila melanogaster (Diptera: Drosophilidae)
TLDR
It is concluded that when body size is significantly induced by temperature variability, it is not correlated with male mating success. 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
AN INTERACTION BETWEEN ENVIRONMENTAL TEMPERATURE AND GENETIC VARIATION FOR BODY SIZE FOR THE FITNESS OF ADULT FEMALE DROSOPHILA MELANOGASTER
TLDR
There was a strong interaction between temperature and size selection for both survival and lifetime reproductive success, with larger females living significantly longer and producing more offspring over their lifetime only when reared and tested in the colder environment. Expand
LOCOMOTOR PERFORMANCE OF DROSOPHILA MELANOGASTER: INTERACTIONS AMONG DEVELOPMENTAL AND ADULT TEMPERATURES, AGE, AND GEOGRAPHY
TLDR
Speed was generally greatest for flies reared at an intermediate developmental temperature, contrary to the beneficial acclimation hypothesis, which predicts that speed would be greatest when influenced by interactions involving population. Expand
Temperature dependence of fitness components in geographical populations of Drosophila melanogaster: changing the association between size and fitness
TLDR
This study considers both preadult and adult fitness components, and shows that large adults from a cold adapted population significantly outperform small adults fromA warm adapted population only when tested at low temperature and low larval density. Expand
THERMAL EVOLUTION OF EGG SIZE IN DROSOPHILA MELANOGASTER
TLDR
It is not clear which life‐history traits are direct targets of thermal selection and which are showing correlated responses, and disentangling these is a task for the future. Expand
TEMPERATURE‐INDUCED SHIFTS IN ASSOCIATIONS OF LONGEVITY WITH BODY SIZE IN DROSOPHILA MELANOGASTER
TLDR
The results suggest that trait associations (including the commonly observed trade‐off between body size and DT) can greatly depend on temperature, as a shift in the sign of the correlation is possible at low temperature. Expand

TLDR
Robertson (1957) examined the nature of genetic variation and covariation between body size and egg production in a large, genetically variable laboratory population of Drosophila melanogaster under benign and uniform rearing conditions, in a characteristically rigorous and detailed study. 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
Heritable variation for territorial success in two Drosophila melanogaster populations
Abstract Male fruitflies from stocks from two localities were artificially selected for defence of a food area against intruding males. Both stocks showed a rapid replicable response to selectionExpand
Lifetime mating success of male fruitflies (Drosophila melanogaster) is related to their size
TLDR
A laboratory population of fruitflies, which showed considerable variance for size, associated with adult emergence at different times after the introduction of food sources to a population cage, showed that larger males had higher lifetime mating success than smaller males. Expand
Temperature-Related Divergence in Experimental Populations of DROSOPHILA MELANOGASTER. I. Genetic and Developmental Basis of Wing Size and Shape Variation.
TLDR
Temperature-directed selection was identified for both wing size and shape of Drosophila melanogaster, and both wing and cell areas show genetic divergence, particularly in the posterior compartment. Expand
Territoriality in Drosophila melanogaster as a conditional strategy
TLDR
The findings suggest that D. melanogaster males are more likely to express territorial behaviour when territory defence is associated with a mating advantage. Expand
Ecology of body size in Drosophila buzzatii: untangling the effects of temperature and nutrition
TLDR
Measurements of adult flies emerging from individual breeding substrates show that there is substantial variation among these substrates in the nutrition available to larvae, and this method will allow study of spatial and temporal variation in the temperature of larval substrates and in the nutritional resources available to flies in natural populations.

THE RESPONSES OF DROSOPHILA MELANOGASTER TO ARTIFICIAL SELECTION ON BODY WEIGHT AND ITS PHENOTYPIC PLASTICITY IN TWO LARVAL FOOD ENVIRONMENTS
To investigate the potential response to natural selection of reaction norms for age and size at maturity, fresh body weight at eclosion was mass selected under rich and poor larval food conditionsExpand
Male size and mating success in Drosophila melanogaster and D. pseudoobscura under field conditions
TLDR
Results on Drosophila in the field confirm and extend those previously obtained in the laboratory, and in both species larger males delivered more courtship and in D. pseudoobscura they won more aggressive encounters. Expand
A laboratory study of male territoriality in the sibling species Drosophila melanogaster and D. simulans
TLDR
Defence of food cups by males of the fruiflies Drosophila melanogaster and D. simulans was examined in the laboratory, and territorial males were more successful in mating than non-territorial males. Expand
The ecological genetics of growth in Drosophila 6. The genetic correlation between the duration of the larval period and body size in relation to larval diet.
TLDR
The pattern of larval growth suggests a flexible system which can be adjusted to different ecological conditions since the same body-size can be attained by adjusting the amount of growth effected before or after the critical stage. Expand
