【摘要】 粪便由于容易辨识来源,方便收集并且可以提供动物食性分析、肠道寄生虫、种群数量、群体遗传学方面的信息而成为野生动物非损伤性采样的主要方式而被广泛采用。在食性分析方面,使用粪便残渣,同位素分析,植物表皮烷类蜡质,近红外以及DNA条码技术,能够获得不易观察的动物的食性数据;利用粪便中的寄生虫幼虫或虫卵可以调查野生动物肠道寄生虫侵染情况;在种群数量统计方面,粪堆计数法由于简便而广被使用,另一种粪便种群研究方法是非损伤标记重捕法,该法虽然会受到DNA质量的困扰,但是由于可以获得家域、性别比信息而成为今后的发展方向;在群体遗传学方面,通过对粪便DNA反复扩增,能够保证遗传信息的准确性。更多还原

【Abstract】 Study of faeces is widely used as a noninvasive sampling method for analysis of diet,intestinal parasites,population size and genetics,and various studies of wildlife because faeces are readily identified to species and easily collected.Examination of plant fragments,isotopes,natural alkanes of cuticular wax.near-infrared reflectance spectroscopy and DNA bar codes were the most useful methods for diet analysis.Larvae or eggs from parasite in faeces could be used to survey intestinal parasite infections of wildlife.Pellet group counts method is widely used for demographic studies,while.noninvasive tagging re-sample is increasingly popular for multi-use in home range and sex-ratio studies,even though it is affected by quality of faeces DNA.Beyond those uses,study of variations in population genetics relies on the quality of DNA in faeces by repeating experiment.更多还原
