Thermal Acclimation and Heat Resistance in Drosophila Species

Open access
Levins, Richard·1969·The American Naturalist

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.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
