【摘要】 甘肃兴隆山国家级自然保护区的野生马麝分娩从 5 月开始产仔, 分娩季节 (75%的分娩累计完成时间) 长27天, 平均分娩日期为5月31日±1 85天, 气候和食物的季节变化决定野生马麝的分娩定时和同期化格局; 保护区内的圈养马麝多在6月分娩, 分娩季节长54天, 同期化比野生马麝为弱, 圈养马麝的分娩时间格局受气候、食物等因子的影响。此外, 圈养种群内个体间的相互作用及各饲养区的管理模式也对马麝的分娩定时产生效应, 性经历影响其分娩的时间格局, 初产雌麝 (primiparous) 的平均分娩日期 6 月 29 日±4 29 天, 比经产雌麝 (multiparous) 迟 (6月19 日±1 47天)。更多还原

【Abstract】 This study was conducted from 1997 to 2000 in Xinglongshan National Nature Reserve, Gansu Province. The birth dates of wild and captive Alpine musk deer were examined to determine fawning patterns, and potential influencing factors discussed. In the wild, parturition shows strong seasonality, and occur in three months from May to July.Most of the births (75%) occurs within 27 days period.In captivity,parturition shows constancy between years and seasonality, although with later initiation and a longer season than in the wild. Although the parturition pattern is not strongly related to age of the captives, an individuals reproductive history seems to influence parturition timing and synchrony, and the birth date is not strongly related to the survival of the newborn.更多还原
