自动温度记录技术在斑尾榛鸡产卵孵卵节律研究中的应用

THE APPLICATION OF DATA LOGGER TECHNIQUE TO THE STUDY OF INCUBATION RHYTHMS OF THE CHINESE GROUSE

以莲花山斑尾榛鸡 (Bonasasewerzowi)的研究结果为例 ,介绍了利用自动温度记录器技术研究鸟类产卵孵卵节律的方法 .研究表明 ,斑尾榛鸡雌鸟每隔 2d产 1枚卵 ,通过分析 1只斑尾榛鸡雌鸟整个孵卵期的孵卵节律 ,发现它平均每天出巢 (5 .5 5± 0 .80 )次 (4～ 7次 ,n =2 2 ) ,平均每次出巢时间为 (17.6± 6 .77)min .雌鸟早晨出巢的时刻平均为 6 :0 7± 2 3min ,傍晚出巢的回巢时刻平均为 19:4 0± 2 2min ,日活动期平均为 (812 .5± 35 .1)min .雌鸟出巢的时间长度与环境温度呈正相关 (Spearman相关检验 ,r =0 .2 6 4 ,p =0 .0 0 4 ) 。

Data logger technique is important for studying the avian laying and incubation rhythms. Data logger technique is introduced to study the egg laying and incubation rhythms of the Chinese grouse, an endemic and endangered bird in the conifer forest in the Qinghai Tibet Plateau. This is the first time to apply this technique in China. One female Chinese grouse lays eggs every two days and spends more time on the nest as the laying period progresses. One Chinese grouse female takes 5.55 recesses per day, and average recess time is (17.6±6.77) min. The active day for the bird is (812.5±35.1) min. The length of recess time is positively correlated to the ambient temperature (Spearman, r=0.264, p =0.004).
