Abstract:
中文摘要:食物是影响野生动物生存的关键因子之一,食性研究是了解野生动物与其生存环境关系的重要内容,也是评价动物生存状况和栖息地质量的基础工作。通过粪便显微分析法对内蒙古赛罕乌拉国家级自然保护区中华斑羚 Naemorhedus griseus的食物季节性构成分析,发现中华斑羚全年取食植物16科27属31种,冬季取食植物种类与其他各季节的差异有高度统计学意义( χ 2=28.865, P<0.001),食物种类明显低于其他3个季节。各季节取食乔木的比例均最低,且冬季取食乔木种类仅1种。全年取食非禾本科草本种类各季节的差异有高度统计学意义( χ 2=17.213, P<0.001),冬季明显低于其他季节。Shannon-Wiener多样性指数和食物生态位宽度由高到低依次为夏季、秋季、春季、冬季,而Pielou均匀度指数由高到低依次为夏季、秋季、冬季、春季。本研究结果表明,中华斑羚的食物选择对栖息地的植被变化具有一定适应性,受植物丰富度和可食部位,以及自身的季节性活动范围和能量平衡等因素的综合影响。
英文摘要:Food is one of the key factors affecting wildlife survival. Food habits study helps us to understand the important relationship between wildlife and their living environment, and can also be used to evaluate the quality of the animals' living conditions and their habitats. The seasonal diet variation of the Chinese goral ( Naemorhedus griseus) was studied through microscopic analysis of the fecal contents in Saihanwula National Nature Reserve. The results showed that 31 plant species belonging to 27 genera and 16 families were foraged by N. griseus in the whole year. The composition of plant species was extremely significant different from other 3 seasons, which was extreme significantly lower during winter ( χ 2=28.865, P<0.001). The proportion of arborous plants in goral's diet were the lowest in all seasons, and the species of arborous plants in winter was the least with only 1 species. Additionally, the proportion of forbs had extremely significant seasonal changes ( χ 2=17.213, P<0.001), which was consumed less in winter than in other seasons. The Shannon-Wiener diversity index and food niche width from high to low were summer, autumn, spring and winter, while Pielou's evenness index in order (from high to low) were summer, autumn, winter and spring. The results showed that the feeding habits of N. griseus had certain adaptability to the seasonal changes of vegetation, and could be affected by an integrative factor of plants richness, arable parts, seasonal activities and energy budget of the animal. 2018,37(3): 311-316 收稿日期:2017-11-24 DOI:10.11984/j.issn.1000-7083.20170375 分类号:Q959.8 基金项目:国家林业局野生动物保护救护繁育项目 作者简介:唐书培,男,硕士研究生,研究方向为动物行为生态学,E-mail:tangshupei@outlook.com *通讯作者:鲍伟东,E-mail:wdbao@bjfu.edu.cn 参考文献: 昶野. 2010. 贺兰山岩羊食性分析[D]. 哈尔滨:东北林业大学. 高中信, 陈化鹏, 王筱平. 1991. 粪便分析法测定植食动物食性的评价[J]. 兽类学报, 11(3):186-193. 郭相保, 王振龙, 陈菊荣, 等. 2011. 河南太行山自然保护区猕猴冬春季食性分析[J]. 生态学杂志, 30(3):483-488. 蒋志刚, 马勇, 吴毅, 等. 2015. 中国哺乳动物多样性及地理分布[M]. 北京:科学出版社. 蒋志刚, 江建平, 王跃招, 等. 2016. 中国脊椎动物红色名录[J]. 生物多样性, 24(5):500-551. 蒋志刚. 2004. 动物行为原理与物种保护方法[M]. 北京:科学出版社. 李邦, 林恭华, 谢久祥, 等. 2014. 托勒南山半圈养白唇鹿食性分析[J]. 四川动物,
