BACKGROUNDProgress in understanding senescence requires information about age-dependent changes in individual organisms. However, for experimental systems such as Drosophila melanogaster we usually do not know whether population trajectories are an a

Populations of Drosophila melanogaster that have been artificially selected for late age of reproduction evolve longer life spans and, in some cases, reduced early fecundity. The negative correlation is widely interpreted as evidence of antagonistic

Among mammals, body size and life span tend to vary inversely within species, but the pattern is less clear in invertebrates. Here, we report on survival and weight of male flies from 29 laboratory strains of Drosophila melanogaster. Natural variatio

We measured age-specific metabolic rates in 2861 individual Drosophila melanogaster adult males to determine how genetic variation in metabolism is related to life span. Using recombinant inbred (RI) lines derived from populations artificially select

We examined the association between body mass and metabolic rate in Drosophila melanogaster under a variety of conditions. These included comparisons of body mass and metabolic rate in flies from different laboratory lines measured at different ages,

An approach towards analyzing survivorship data is proposed for the study of changes in stress resistance with age in the population of Drosophila melanogaster. This is based on the model of heterogeneous mortality (frailty model). Results of the dat

The use of model organisms, such as Drosophila melanogaster, provides a powerful method for studying mechanisms of aging. Here we report on a large set of recombinant inbred (RI) D. melanogaster lines that exhibit approximately a fivefold range of av

We have constructed a set of 120 recombinant inbred lines for use in studies of the genetics of lifespan in Drosophila. The lines are derived from Luckinbill and Clare's (Heredity 55 (1985) 9) artificial selection experiment for increased lifespan. I

Adult lifespans, age-specific survival, age-specific mortality, survival times on paraquat, and survival times on DDT were assayed in seven lines of Drosophila melanogaster, including two genetically heterogeneous wild lines recently collected from n

Age-specific mortality rates decelerate at older ages in both genetically homogenous and heterogeneous populations of Drosophila . One explanation proposed for deceleration is population heterogeneity. This hypothesis suggests that a population consi
