Summary

ABSTRACT: Latitudinal clines have been demonstrated for many quantitative traits in Drosophila and are assumed to be due to climatic selection. However, clinal studies are often performed in species of Drosophila that contain common cosmopolitan inversion polymorphisms that also show clinal patterns. These inversion polymorphisms may be responsible for much of the observed clinal variation. Here, we consider latitudinal clines for quantitative traits in Drosophila simulans from eastern Australia. Drosophila simulans does not contain cosmopolitan inversion polymorphisms, so allows the study of clinal selection on quantitative traits that are not confounded by associations with inversions. Body size showed a strong linear cline for both females and males. Starvation resistance exhibited a weak linear cline in females, whereas chillcoma recovery exhibited a significant nonlinear cline in females only. No clinal pattern was evident for development time, male chill-coma recovery, desiccation or heat resistance. We discuss these results with reference to the role inversion polymorphisms play in generating clines in quantitative traits of Drosophila.

Datasets

  • 77 Arthur et al. 2008, Cold resistance

    This data file contains cold recovery time (minutes) for females and males of 10 Drosophila simulans populations collected in 2004. For each population, 11-15 lines were tested for females and 9-15 lines for males (Fig. 1). Note longitudes in data are approximate.

  • 78 Arthur et al. 2008, Desiccation resistance

    This data file contains desiccation resistance (time to death in hours) for individual females of 10 Drosophila simulans populations collected in 2004. For each population, 12-15 lines were tested (Fig. 3). Note longitudes in data are approximate.

  • 79 Arthur et al. 2008, Development time

    This data file contains egg-to-adult development time (hours) for 10 Drosophila simulans populations collected in 2004. For each population, 12-15 lines were tested (Fig. 4). Note longitudes in data are approximate.
