Mortality
downin animals1−15% mortality risk with each standard deviation increase in tl
Early-life telomere length lowers the risk of mortality (15% reduction in mortality risk with each standard deviation increase in TL).
“Overall, the effect of early-life TL on mortality was significant, corresponding to a 15% reduction in mortality risk with each standard deviation increase in TL.”

Early-life telomere length is associated with lifetime reproductive success in M. coronatus.
“early-life TL was positively related to breeding duration, contribution to population growth and lifetime reproductive success because of their association with lifespan.”
