In 1978 Social Science and Medicine published Barbara L.K. Pillsbury's article, "'Doing the Month': Confinement and Convalescence of Chinese Women After Childbirth," which summarized the results of Pillsbury's study on Chinese childbirth customs. Pillsbury, a professor of cultural anthropology at San Diego State University in San Diego, California, conducted over eighty interviews with people i...

BACKGROUND Ability to resist temperature shock is an important component of fitness of insects and other ectotherms. Increased resistance to temperature shock is known to affect life-history traits. Temperature shock is also known to affect reproductive traits such as mating ability and viability of gametes. Therefore selection for increased temperature shock resistance can affect the evolution...

the spider mite, t. turkestani, is considered as one of the most important polyphagous pests of many crops. its reproductive ability, developmental time, preimaginal mortality and reproduction rate were determined on kidney bean at 20, 25 and 30°c,70±5% rh and 16l:8d. female longevity and immature developmental period (6.74 and 5.8 days, respectively) were shorter at 30°c than at 20 and 25°c. t...

In order to reproduce successfully, animals must integrate multiple environmental cues to synchronize breeding with favorable conditions. In temperate, seasonally breeding rodents, photoperiod acts as the primary seasonal cue. Long days are associated with reproductive development and maturation of the gonads whereas short days induce gonadal regression. The neuropeptide kisspeptin has potent s...

Diet has a profound direct and indirect effect on reproductive success in both sexes. Variation in diet quality and quantity can significantly alter the capacity of females to lay eggs and of males to deliver courtship. Here, we tested the effect of dietary resource limitation on the ability of male Drosophila melanogaster to respond adaptively to rivals by extending their mating duration. Prev...
