Thermal Acclimation and Heat Resistance in Drosophila Species
Year: 1969
Type: article
Abstract: Physiological and developmental acclimation to dry heat as measured by survival at 38⚬ C was studied in several species of Drosophila. Physiological acclimation occurs rapidly (about half-completed in 12 hr), is quickly lost, and does not depend on water uptake. In broad-niched species, and especially in D. melanogaster, adaptation to different climates depends mostly on individual flexibility and less on genetic differences among populations. None of the narrow-niched species acclimate. The D. willistoni, a moderately broad-niched species, does not acclimate nor show much genetic variation. It is suggested that this species avoids desiccation stress behaviorally.
