Abstract: To know the home range utilization and group dynamics of all-male band, GS band was followed daily in Luobai from September 2000 to August 2001, which was composed of four subadult males. The result showed that the home range of GS band was about 62.4 ha, with 73.8% overlapped those of neighboring bisexual troops. The overlapped areas made the home range of GS band larger than those of bisexual troops. There were significant seasonal changes in the percent of time GS band spent in different part of the home range.

Key words: white-headed langur, all-male band, home range utilization

摘要: 为了解白头叶猴全雄群的巢域利用状况及其未来走向,从2000年9月至2001年8月,作者对一个新形成的全雄群GS群进行了为期一年的跟踪观察。通过最小面积法确定GS群的巢域总面积为62.4 ha,其中与邻群的重叠巢域占总面积的73.8%,这很可能是其巢域远大于已知一雄多雌群的直接原因。通过分析群在巢域各部分活动的月时间比例,发现GS群对特有巢域和重叠巢域的利用存在显著的季节性差异。
