Summary

ABSTRACT: The duration of Drosophila melanogaster larval and pupal periods was measured in laboratory thermal lines and in populations collected along a latitudinal transect in eastern Australia. In replicated laboratory lines kept for 9 years at 16.5" C or 25" C the duration of larval development had continued to diverge compared with 4 and 5 years previously, with more rapid larval development, and hence reduced total duration of pre-adult development, in the low temperature lines at both experimental temperatures. After 4 years of separate evolution, lines derived from the 25" C lines and subsequently cultured at 29" C showed no evidence of significant divergence in the duration of any part of the pre-adult period. The geographic populations showed a decrease in the duration of larval development, and hence of the total pre-adult period, with increasing latitude. In both laboratory and field populations, evolution at lower temperature was associated with more rapid larval development to a larger adult body size, the opposite genetic correlation between these traits to that found within a single temperature. The indications are that lower temperatures may be permissive of more efficient growth in D. melanogaster. It will be important to discover if evolution in response to temperature induces similar correlations in other ectotherms.
