(2) We quantified the relationship between survival over a three-year period and plasma corticosterone concentrations: (1) baseline, (2) stress-induced, (3) after induction of negative feedback via dexamethasone injection and (4) after maximal adrenal stimulation via adrenocorticotropin hormone injection.
(3) Only stress-induced corticosterone predicted survival, with higher concentrations being associated with lower survival. However, this effect differed significantly between the sexes, being present only in males.
(4) Stress-induced corticosterone concentration is the sum of baseline corticosterone and the corticosterone increase in response to the standardised stressor, and both components were similarly associated with male survival in a model that included both variables. This implies that baseline corticosterone itself also exerts an effect on male survival, but this was only revealed when the stress induced corticosterone increase was included in the model, presumably because this increased statistical power.
(5) Given that corticosterone concentrations are highly repeatable in our study population and independent of manipulated foraging conditions, these data suggest that endocrine stress reactivity may be a major component determining male lifespan, presumably also in wild populations.
The data package contains one dataset:
- sd is the abbreviation for the standardized variables as they were used in the statistical analyses. M: male; F: female.
