Many large marine megavertebrates (e.g. sharks, turtles, mammals, seabirds) are particularly vulnerable to anthropogenic mortality due to their complex life history characteristics, including long lifespans, delayed maturity, low fecundity, and extended migrations [ 1– 4].
These data demonstrate that rapid age-dependent decline and short lifespan are natural characteristics of this species.
The seed production potential of plants has often been studied in relation to three connected characteristics: lifespan, self-incompatibility, and genetic load (the presence of deleterious recessive alleles in a population).
To separate natal from current environmental effects on recruit production, we also included individual characteristics (lifespan and age at first reproduction) and environmental effects (natal total population size, local natal population density, current breeding agriculture, and current rainfall) that might affect current reproductive success.
However, cell cycle checkpoint stringency may be associated with parameters other than lifespan which are characteristic of a particular species.
Substrate potential, plasma-po1ymerized hexamethy1disiloxane (PPHMDS) film adhesion strength, partial discharge characteristics, and lifespans of composite films exposed to partial discharges in a sphere-plane electrode system were investigated.
Specifically, electrochemical capacitor is an energy facilitator that exhibits an efficient/economical charging and discharging characteristics with long lifespan.
There have been several studies investigating characteristics of root lifespan of both woody and herbaceous species.
The increase in root lifespan exhibited spatial and temporal characteristics such that it increased lifespan for roots distributed in the top two soil layers and for roots born in summer and spring, but it had no effect on lifespan of roots in the deep soil layer and born in autumn.
Subjects were sampled from the Personality and Total Health Through Life (PATH) project, a large longitudinal study of ageing aimed at investigating the course of mood disorders, cognition, health, and other individual characteristics across the lifespan [ 53].
As mentioned above, body size is an important life history characteristic for male bighorn sheep as it relates to access to females, while larger females have been found to have longer lifespans [ 64].
