“…Tuci6 (1979) carried out long term selection experiments to improve the cold resistance of D. melanogaster at all developmental stages, and then studied the genetic basis for the change, finding genes controlling it located on all major autosomes. Kimura (1982aKimura ( , 1982b and Fukatami (1984) investigated the closely related species, D. takahashii Sturtevant and D. lutescens Okada, of which the latter is the more northerly and, as expected, more resistant to cold stress. Genetic investigation suggested that genes causing this difference in cold resistance are located both on the X chromosome and on the autosomes (Fukatami, 1984).…”

The genetic basis of the difference in cold shock tolerance between the southern temperate Drosophila virilis and its boreal relative D. lummei is studied. After adult eclosion, the parental stocks, reciprocal F1 and backcross hybrids were pretreated for eight days at 18 degrees C or at 6 degrees C. The cold shock used consisted of fast cooling to -10 degrees C and exposure to this temperature for varying lengths of time. D. lummei tolerated such exposure for 40-50% longer than did D. virilis (100-135% after acclimation). Reciprocal F1 females, differing only in their maternal cytoplasm deviated significantly from each other, and the reciprocal F1 males even more so, the contribution of the X chromosome being three to four times that of the cytoplasm. The cold resistance scores of the hybrid males were more extreme than those of the parental stocks. Autosomally heterozygous males with the X chromosome and cytoplasm of virilis were the weakest flies studied. The reciprocal males (X chromosome and cytoplasm of lummei) survived better than the parental lummei stock. The reciprocal differences decreased after cold temperature acclimation. The roles of the four major autosomes were analyzed by backcrossing the reciprocal F1 males with females of the virilis marker stock. The third chromosome of lummei as heterozygous contributed most to cold tolerance, while the other autosomes had a rather weak effect in the opposite direction (virilis homozygotes survived better), which disappeared after acclimation at 6 degrees C. Some of the cold susceptibility of F1 hybrids disappeared in chromosomally identical backcross flies, indicating complex cytoplasm-chromosomal interactions.

“…In contrast to the remarkable difference in cold-hardiness among these species, little or no intraspecific variation was observed in their cold-hardiness, in spite of the considerable variation in winter temperature within the species' ranges (also see Fukatami [1977] and Kimura [1982b]). Therefore, cold-hardiness is likely to be one of the main factors restricting their distributions at high latitudes.…”

The Drosophila melanogaster species group is considered to have originated in the tropics and only recently invaded temperate habitats. The temperate species of this group that were studied here may be subdivided into the warm-temperate species (D. lutescens and D. rufa) and the cool-temperate species (species of the auraria complex). The warm-temperate species were more cold-hardy than were their tropical relatives (D. takahashii or D. melanogaster) at the larval and imaginal stages, and the cool-temperate species were more cold-hardy than the warm-temperate species, although only at the imaginal stage. However, these species showed little or no intraspecific variation in cold-hardiness, in spite of great variation in winter temperature within the species' ranges. It is assumed that cold-hardiness is one of the main factors restricting their distributions at high latitudes and that it is the key for evolution of the warm- and cool-temperate species from their subtropical or warm-temperate ancestors. Both warm- and cool-temperate species had photoperiodically controlled reproductive diapause. In the cool-temperate species, the development of cold-hardiness was affected by diapause, but diapause had little or no effect on cold-hardiness in the warm-temperate species. Critical daylengths and the diapause rates varied from species to species according to variation in their overwintering plans and also varied geographically in consequence of their adaptation to local climates. Species showed different responses to temperature in preimaginal and ovarian development. These differences are considered to reflect adaptation to different environmental temperatures.

“…Variation in resistance to environmental stress has been observed among related species and populations of Drosophila from climatically different regions, particularly for heat (Hosgood and Parsons, 1968; Parsons, 1979;Coyne et al, 1983), and cold shock resistance (Jefferson et al, 1974; Tucic, 1979;Marinkovic et al, 1980;Kimura, 1982;Fukatami, 1984;Heino and Lumme, 1989;Hoffmann and Watson, 1993), and this variation appears to be an evolutionary response to the environment (Hoffmann and Parsons, 1991;Loeschcke et al, 1994). Success in selecting for stress resistance indicates that a significant additive genetic component also is present within populations (Morrison and Milkman, 1978; Kilias and Alahiotis, 1985; b; Jenkins and Hoffmann, 1994; Krebs and Loeschcke, 1996).…”
