神农架两个大小不同的川金丝猴群的家域变化:对食物竞争的启示

Home range variation of two different-sized groups of golden snub-nosed monkeys (Rhinopithecus roxellana) in Shennongjia, China: implications for feeding competition

  • 摘要: 家域大小对理解一个物种或种群的行为和社会生态学、以及改善其保护策略有重要意义。我们研究了神农架两个大小不同的川金丝猴群(Rhinopithecus roxellana)的家域大小。大群包含236只个体,在2007年9月至2008年7月间的家域达到22.5 km2,而小群包含62只个体,在2008年11月至2009年7月间的家域为12.4 km2。两个猴群的家域大小都呈现明显的季节性变化,这种现象可能与食物可获得性和食物分布的季节性变化有关。在任何季节(冬季、春季、夏季或冬季+春季+夏季),大群的家域都比小群的家域大。由于两个猴群生活在同一区域,从而食物可获得性的混淆效应最小化,因此家域大小和群体大小之间的正相关关系暗示大群个体间的食物竞争更为激烈。

     

    Abstract: Knowledge on the home range size of a species or population is important for understanding its behavioral and social ecology and improving the effectiveness of conservation strategies. We studied the home range size of two different-sized groups of golden snub-nosed monkeys (Rhinopithecus roxellana) in Shennongjia, China. The larger group (236 individuals) had a home range of 22.5 km2 from September 2007 to July 2008, whereas the smaller group (62 individuals) occupied a home range of 12.4 km2 from November 2008 to July 2009. Both groups exhibited considerable seasonal variation in their home range size, which was likely due to seasonal changes in food availability and distribution. The home range in any given season (winter, spring, summer, or winter+spring+summer) of the larger group was larger than that of the smaller group. As the two groups were studied in the same area, with the confounding effects of food availability thus minimized, the positive relationship between home range size and group size suggested that scramble feeding competition increased within the larger group.
