title: Life span of springtail on 12-hr shifts at varying intervals of 12-hr alternation in ambient temperature.
abstract: The effect of shifts at different intervals of a regimen of quasioptimal and nonoptimal ambient temperatures alternating at 12-hr intervals was tested on the springtail, Folsomia candida. Life span data demonstrate that shifts of the temperature regimen can be optimized to prolong life rather than to shorten it or to leave it unaffected. Optimal shift intervals are 7 days apart, in keeping with the results on effects of shifts of a regimen of alternating light and darkness in a giant alga, Acetabularia mediterranea, and in the face fly, Musca autumnalis.
