摘要(Abstract)：

本文以广西崇左国家级自然保护区弄官山片的白头叶猴(崇左种群)为研究对象,并结合扶绥九重山片和咘遵片猴群(扶绥种群)食性研究结果,比较分析白头叶猴食物组成的区域性差异,探讨白头叶猴对喀斯特石山森林破碎化的食性适应策略。结果表明:白头叶猴2个地理种群共采食181种植物,隶属于63科129属,其中,乔木和灌木121种,藤本46种,草本13种,寄生植物1种。2个地理种群的食物种类重叠率为15.8%,崇左种群的食物多样性指数明显高于扶绥种群(4.1vs 2.7),说明白头叶猴猴群可能通过拓宽食谱(即增加食物种类)来获得足够的食物,以应对栖息地破碎化和人为干扰带来的变化。崇左和扶绥2个地理种群均表现出高度的叶食性,比较发现2个地理种群的觅食部位没有明显的地域差距,可能与严重破碎化栖息地内高质量食物(如果实)极度缺乏有关。

关键词(KeyWords)： 白头叶猴;食物组成;地域差异;破碎化生境
