摘要
通过为期一年的标志重捕研究,获得了农田优势种黑线姬鼠与臭鼩的巢区、活动距离、领域性等资料,分析了种间领域性及空间分布的关系。并观察到随着捕获次数增多,对动物的可捕性产生影响,再结合对重捕期体重变化的分析,发现长期标志重捕对两种动物产生了正与负的效应。
Some ecological data of Apcdemus agrarius and Suncus murinus were obtained from a mark-recapture method carried out on the faimland between Nov.,1986 and Oct., 1987. The average home range size of A, agrarius was 2271±204.1m2 for males and 1841 + 183.1m2 for females. There was no territoriality in males, but females showed feme evidence of territoriality. The home range size of males of Suncus murinus ave-raged 1227±263.0m2, and that of females 241.4±50.3m2. However, ro territoriality was found in the shrews.
The two species showed overlap in their home ranges although the areas preferred -by A. agrarius seldom overlapped those preferred by S.murinus.
A.agrarius was confirmed to be capture-prone. The mean body weight of A.agrar-ius did not change significantly within one retrapping period (10 days),but S,murinus showed a decrease of body weight due to marking and capturing.
