Thoracic trident pigmentation in natural populations of Drosophila simulans: a comparison with D. melanogaster


By contrast with Drosophila melanogaster, wild living D. simulans adults generally do not exhibit a thoracic dark pigmentation with a trident shape. This trident however appears when development occurs at low temperature. A study of 26 natural populations from various parts of the world revealed a significant latitudinal cline, expressed only at 17° C. The… (More)
