Implication

Comparative analysis reveals variable longevity benefits across captive mammals, indicating that slow-living species gain less survival advantage in zoos.

Key Points

To test whether living in zoos confers a survival advantage over wild conditions across diverse mammalian species and life histories.
Evaluated four survival metrics—longevity, baseline mortality, onset of senescence, and rate of senescence—between free-ranging and captive populations.
Analyzed demographic data for both sexes across more than 50 mammalian species.
Mammals in zoo populations outlived their wild counterparts across 84% of evaluated species.
Longevity gains were greatest for fast-paced species facing high wild mortality and predation, whereas slow-paced species exhibited substantially smaller survival benefits in captivity.
