Abstract
Most studies on wild ornate box turtles (Terrapene ornata) estimate maximum age in the 30s with some data suggesting that individuals may live beyond 50. We present data from a 29-yr study of 374 marked turtles in which at least 44% lived into their 30s and at least 3.5% survived into their 40s. Females may survive longer than males. Older turtles can affect reproductive potential of the population; therefore, conservation and management for this state-threatened species should account for longer lifespans than previously assumed.
期刊介绍：
Chelonian Conservation and Biology is a biannual peer-reviewed journal of cosmopolitan and broad-based coverage of all aspects of conservation and biology of all chelonians, including freshwater turtles, marine turtles, and tortoises. Manuscripts may cover any aspects of turtle and tortoise research, with a preference for conservation or biology. Manuscripts dealing with conservation biology, systematic relationships, chelonian diversity, geographic distribution, natural history, ecology, reproduction, morphology and natural variation, population status, husbandry, community conservation initiatives, and human exploitation or conservation management issues are of special interest.
