"John McCain has been in Congress 25 years — no doubt about that — if this is a longevity measure, then John McCain wins," Mr. Obama said.
Epidemiologically, the most important life history attribute of female Anopheles vectors of human malaria is their life span, i.e., their longevity measured in days.
However, these genes account for only a small portion of the genetic contribution to longevity measured through family heritability studies [ 49].
Analysis of (A) the effect of aphid line on cumulative fecundity (linear mixed model), (B) the effect of resistance to parasitism on cumulative fecundity (linear mixed model), (C) the effect of aphid line on aphid longevity (repeated measures MANOVA), (D) the effect of aphid resistance on longevity (repeated measures MANOVA).
Stayability is an indicator of longevity that measures the proportion of animals remaining productive to a fixed time endpoint [ 1].
In addition, the phenotypic effects of growth hormone (GH) transgenesis in fish and mice include shorter lifespans compared to wild-type controls, further supporting a trade-off between investments in growth and longevity assurance measures (e.g. [ 5– 7]).
Measurement theory notifies that the TTO method cannot be classified as an accurate (unidimensional) measurement method for health states, because two distinct phenomena (health status, longevity) are measured simultaneously.
The research determined a link's longevity by measuring its half life — the point at which it has received half the clicks it will receive online.
Reasoning that mating might have an effect on longevity, we measured the life span of mated and non-mated groups respectively.
Longevity was measured as days from eclosion through death in mated males and females housed singly up through four flies per vial and transferred to fresh, yeasted vials with every 2 5 days.
