Temperature-dependent trade-offs between longevity and fertility in the Drosophila mutant, methuselah.

Abstract excerpt

Single gene, hypomorphic mutations which extend the life spans of cold-blooded animals, such as the methuselah (mth) mutation in the fruit fly, Drosophila melanogaster, may have additional, deleterious effects on overall fitness. The hypotheses tested here were: (i) that the extension of life span by mth might be temperature-dependent, and (ii) that it might be associated with depression of reproductive output,...
