Much of the work of demography is directed at the study of lifespan.
The effects of density dependence on the evolution of lifespan and mortality remain largely unexplored.
One particular area of progress is the molecular genetics of lifespan.
This paper finishes by discussing the findings from the perspectives of lifespan, monitoring, ownership, and standardization.
GLM univariate procedure revealed higher contribution of Ap to the variance of lifespan compared to season of death.
And that's based on "conservative" estimates of lifespan, not those that factor in rapid technological advances.
SIR2 was the first identified evolutionarily conserved gene which had been implicated in the expansion of lifespan.
The species were characterised on the basis of lifespan into various categories like annuals, biennials and perennials.
This susceptibility to heart attacks, heart failure and other heart conditions is likely at the root of lifespan differences.
In fact, a significant extension of lifespan could not be observed in either sex.
Certainly, the direct association of lifespan with suppressed adiposity is of interest for further study.
