Negligible Senescence during Reproductive Dormancy in Drosophila melanogaster.

摘要: Abstract: Some endemic Drosophila overwinter in a state of adult reproductive diapause where egg maturation is arrested previtellogenic stages. When maintained at cool temperatures, melanogaster enter dormancy, that is, or diapause‐like quiescence. The ability to survive for extended periods typical feature syndromes. In adults this somatic persistence may involve reduced slowed senescence. Here we assess whether reproductively dormant D. age slow rates. Adults were exposed dormancy‐inducing conditions 3, 6, 9 wk. After period, demographic parameters measured under normal and compared the demography newly eclosed cohorts. age‐specific mortality rates postdormancy essentially identical eclosed, young flies. Postdormancy reproduction, contrast, declined with duration treatment; survival during dormancy tradeoff la...
