“…Such temperature-induced plasticity that results in larger offspring at lower temperatures seems to be a near universal rule in ectotherms (Azevedo et al, 1996;Yampolski and Scheiner, 1996;Fox and Czesak, 2000). However, as most previous studies did not distinguish between the effects of larval versus adult temperature, much less is known about the sensitive periods for the induction of the plastic response (Fox and Czesak, 2000).…”

“…However, as most previous studies did not distinguish between the effects of larval versus adult temperature, much less is known about the sensitive periods for the induction of the plastic response (Fox and Czesak, 2000). Likewise, the underlying mechanisms remain obscure (Azevedo et al, 1996;Blanckenhorn, 2000;Ernsting and Isaaks, 2000;Fox and Czesak, 2000). From previous experiments that disentangled developmental plasticity from acclimation in the adult stage, we do know that low oviposition temperatures result in larger eggs (eg Avelar, 1993; Huey et al, Minimum adequate models were constructed by removing the nonsignificant interaction terms.…”

“…Likewise, egg size in ectotherms was commonly found to increase in colder regions and colder seasons (Azevedo et al, 1996;Yampolski and Scheiner, 1996;Blanckenhorn, 2000), and insects lay larger eggs at lower temperatures under laboratory conditions (eg Avelar, 1993;Crill et al, 1996;Sheader, 1996;Ernsting and Isaaks, 1997;Blanckenhorn, 2000). The underlying mechanisms shaping this temperature-size rule as well as its adaptive significance are largely unknown (Azevedo et al, 1996;Crill et al, 1996;Blanckenhorn, 2000;Fox and Czesak, 2000).…”

Genetic and environmental sources of egg size variation in the butterfly Bicyclus anynana

By dividing families of the tropical butterfly, Bicyclus anynana, among different larval (including early pupal) and adult (including late pupal) temperatures, we investigate the genetic and environmental effects on egg size. Both sources of variation affected egg size to similar extents. As previously found in other arthropods, egg size tended to increase at lower temperatures. Our data suggest that the plastic response in egg size can be induced during the pupal stage. Females reared as larvae at the same high temperature tended to lay larger eggs when transferred to a lower temperature, either as prepupae or pupae, compared to those remaining at the high temperature. Additionally, females reared as larvae at different temperatures, but maintained at the same temperature from the early pupal stage onwards, laid larger eggs after larval growth at a low temperature. Heritability estimates for egg size were about 0.4 (parent-offspring regression) and 0.2 (variance component estimates using the full-sib families). Although there seemed to be some variation in the plastic response to temperature among families, genotype-environment interactions were nonsignificant.

Quantitative genetic analysis of natural variation in body size in Drosophila melanogaster

Latitudinal, genetic variation in body size is a commonly observed phenomenon in many invertebrate species and is shaped by natural selection. In this study, we use a chromosome substitution and a quantitative trait locus (QTL) mapping approach to identify chromosomes and genomic regions associated with adaptive variation in body size in natural populations of Drosophila melanogaster from the extreme ends of clines in South America and Australia. Chromosome substitution revealed the largest effects on chromosome three in both continents, and minor effects on the X and second chromosome. Similarly, QTL analysis of the Australian cline identified QTL with largest effects on the third chromosome, with smaller effects on the second. How-

“…First, it is generally believed to be closely related to fitness (Fox & Czesak 2000;for B. anynana see Fischer et al 2003a). Second, it is known to respond readily to differences in both developmental and adult temperature (Azevedo et al 1996;Crill et al 1996;Ernsting & Isaaks 1997;Blanckenhorn 2000;Fischer et al 2003a).…”

We use a full factorial design to investigate the effects of maternal and paternal developmental temperature, as well as female oviposition temperature, on egg size in the butterfly Bicyclus anynana. Butterflies were raised at two different temperatures and mated in four possible sex-by-parental-temperature crosses. The mated females were randomly divided between high and low oviposition temperatures. On the first day after assigning the females to different temperatures, only female developmental temperature affected egg size. Females reared at the lower temperature laid larger eggs than those reared at a higher temperature. When eggs were measured again after an acclimation period of 10 days, egg size was principally determined by the prevailing temperature during oviposition, with females ovipositing at a lower temperature laying larger eggs. In contrast to widely used assumptions, the effects of developmental temperature were largely reversible. Male developmental temperature did not affect egg size in either of the measurements. Overall, developmental plasticity and acclimation in the adult stage resulted in very similar patterns of egg size plasticity. Consequently, we argue that the most important question when testing the significance of acclamatory changes is not at which stage a given plasticity is induced, but rather whether plastic responses to environmental change are adaptive or merely physiological constraints.
