Sentence examples for patterns of lifespan from inspiring English sources

These studies have highlighted how natural and sexual selection can generate divergent patterns of lifespan if the sexes are subject to different rates or sources of mortality, or if trade-offs between complex traits and longevity are resolved differently in each sex.

The perturbation analysis of the Siler model indicates that the conspicuously diverging patterns of lifespan variation by age are due to the differential impact of mortality reduction in childhood and adulthood on the distribution of ages at death.

(D ) The pattern of lifespan modulation by food abundance is maintained across the range of standard C. elegans culture temperatures.

As can be seen in the simulation-based panels in Figure A1, a Gompertz model that includes a term for declines in age-specific mortality over time fails to produce a divergent age-pattern of lifespan variability trends.

These flies lived longer than when housed singly and fed from capillaries, but the pattern of lifespan, egg production and egg production rate in relation to dietary P C ratio was the same.

Perturbation analysis has enabled a more detailed quantification of the influence of changing demographic parameters on the pattern of lifespan variability at all ages, highlighting the impact of declining childhood mortality on the reduction of lifespan variability, and the impact of later improvements in adult survival on the rising variability of lifespans at older ages.

Because a background mortality component that is not age-dependent has not been investigated as thoroughly as mortality specific to childhood or adulthood, we paid special attention to its pattern of decline relative to the other two components, and to its influence on the age-pattern of lifespan variability trends.

Because of its greater capacity to replicate the empirical pattern of diverging lifespan variability trends, the Siler model was used in the subsequent analysis to examine the sensitivity of the age-specific variability measures to actual changes in each parameter over time.

These dynamics across time and age are essential for understanding the patterns of change in life expectancy as well as in the variability of lifespans.

We further tested for a correlation of lifespan and coloration pattern, because all GRZ and MZM-0403 males we have observed to date showed a distinct coloration.

DNA methylation has long been considered as a stable epigenetic mark resulting in maintenance of DNA-methylation patterns throughout the lifespan of an organism.
