1雄性大熊猫尿中睾酮和皮质醇代谢物水平及其与繁殖、笼养和季节的关系(英文)显示文摘收集了雄性大熊猫尿样肾上腺皮质激素和雄性激素代谢物年周期变化基础数据。二月份雄性激素水平最高,与繁殖季节的开始相关。繁殖成功与雄性激素水平无相关,与不同的笼养环境也无相关。与其他熊类物种相比,大熊猫交配和雄性激素水平峰值在一年中的较早时候出现。在大熊猫这样一个多配制物种,这个峰值可以看作与挑战假说相关联。在冬季,肾上腺皮质激素水平逐月升高, 12月份出现峰值。在繁殖季节来临前,肾上腺皮质激素可能扮演了一个预备的角色[动物学报52(2):242-249,2006]。Edith MACDONALD Nancy CZEKALA 王鹏彦 Fernando GUAL-SILL Tatsuko NAKAO 2006动物学报2006,52,2:2
