摘要我们报告了36只人工繁殖的山鸡在加蓬Lékédi公园首次放归的结果。释放后第一年的死亡率为33%，由于环境压力和营养不良，受抚养的婴儿是受影响最严重的年龄组。一项供应方案确保个人保持良好的身体状况。第二年死亡率降至4%，婴儿6个月存活率为100%。随着时间的推移，山鹬扩大了对公园的空间利用，尽管它们的探索仍然有限。我们的研究结果表明，供应和缺乏知识的新的，复杂的季节性栖息地的生态特征是这种情况的可能原因。2年后，繁殖和生存似乎稳定。虽然生境保护和就地物种保护是最好的保护办法，但释放项目可能是某些物种的可行的短期解决办法。在这种情况下，这第一次释放圈养繁殖的山鸡可以在未来保护这一脆弱物种中发挥作用。
Abstract We report the results of the first release project of 36 captive-bred mandrills into the Lékédi Park, Gabon. A mortality rate of 33% was recorded in the first year post-release, with dependent infants the most affected age class, as a result of environmental stress and malnutrition. A programme of provisioning ensured that individuals remained in a good physical condition. During the second year the death rate decreased to 4%, and 6-month survival rate of infants was 100%. Over time the mandrills extended their spatial use of the park, although their exploration remained limited. Our results demonstrate that provisioning and the lack of knowledge of ecological characteristics of the new, complex seasonal habitat were the likely causes of this situation. After 2 years, reproduction and survival appear stable. While habitat preservation and in situ species protection are the best conservation options, release projects may constitute a viable short-term solution for particular species. In this context, this first release of captive-bred mandrills could play a role in the future conservation of this Vulnerable species.
