1. The need to manage exposure to oxidative stress, which can damage macromolecules, is thought to influence the resolution of life-history trade-offs. Oxidative damage is expected to increase with age as a consequence of changes in the optimal inves

Glucocorticoids, including corticosterone (CORT), have been suggested to provide a physiological link between ecological conditions and fitness. Specifically, CORT, which is elevated in response to harsh conditions, is predicted to be correlated with

Personality predicts behavioral flexibility in a fluctuating, natural environment

In captivity, personality types differ in behavioral flexibility: "fast" (neophilic, exploratory, and aggressive) types quickly form routines, whereas "slow" types continually adjust their behavior with environmental changes. If these differences ext

Parental age influences offspring telomere loss

1. The age of the parents at the time of offspring production can influence offspring longevity, but the underlying mechanisms remain poorly understood. The effect of parental age on offspring telomere dynamics (length and loss rate) is one mechanism

Personality in captivity reflects personality in the wild

Publikováno v: Animal Behaviour. 79:835-843

To investigate the ecological significance of personality, researchers generally measure behavioural traits in captivity. Whether behaviour in captivity is analogous to behaviour in the wild, however, is seldom tested. We compared individual behaviou
