中文摘要	广泛分布在北疆的绢蒿荒漠作为重要的春秋牧场,承担着两季的放牧压力。由于该区域气候干燥,放牧家畜的粪便分解强烈依赖于各类粪甲虫。为确定绢蒿荒漠中粪甲虫数量的季节性变化及物种多样性特征,进行了野外调查和取样。结果表明:在石河子紫泥泉种羊场典型绢蒿荒漠放牧地家畜粪便中采集到粪甲虫14797头;其中,捕获的金龟子分属3科19种,蜉金龟科10种,金龟科8种,粪金龟科1种;4-6月物种丰富度逐渐上升,6月物种丰富度最高,优势种为黄缘蜉金龟(Aphodius sublimbatus);春秋放牧季(4-5、9-10月)个体数量多于夏季(7-8月);其中,10月物种丰富度最低,但优势种直蜉金龟(Aphodius rectus)个体数量显著多于其他时间所有物种个体数量;对捕获到的19种金龟子进行DNA的提取及目的基因的扩增和测序结果表明,基于16S rRNA的分类结果与形态学分类结果一致;构建的进化树呈现2个明显分支:第一分支包含蜉金龟科10个物种,均属D型生态功能类群,物种的粪便处理方式在种间具有明显趋同性;第二分支包含了金龟亚科和粪金龟科的9个物种,从生态功能类群上看,存在7个T型物种和2个R型物种,Onthophagus gibbulus、Onthophagus nuchicornis、Gymnopleurus mopsus、Gymnopleurus flayellates虽然亲缘关系接近,但分属两个生态功能类群,在粪便处理方式上表现出种间趋异。
英文摘要	Seirphidium-dominated desert,widely distributed in northern Xinjiang,bears grazing pressure in both spring and autumn.Due to the dry climate,the decomposition of feces of grazing livestock strongly depends on dung beetles.In this study,we recorded the seasonal variation and species diversity of dung beetles in the Seirphidium-dominated desert grassland.A total of 14797 dung-eating insects were captured,belonging to 19 species and 3 families,in which there were 10 species from Aphodiidae,8 species from Scarabaeidae,1 species from Geotrupidae.The species richness gradually increased from April to June.The dominant species was Aphodius sublimbatus.The beetle abundance in spring and autumn grazing season(April to May,September to October)was greater than that in summer(July to August).The species richness was the lowest in October,but the abundance of the dominant species Aphodius rectus was significantly higher than that of all other species.The results of 16S rRNA based classification were consistent with morphological classification.The established evolutionary tree was divided into two distinct branches.The first branch contained 10 Aphodiinae species,which belonged to Dweller.The fecal disposal of species has obvious convergence.The second branch included nine species of Scarabaeidae and Geotrupidae.From the perspective of functional groups,there are seven Tunnelers and two Rollers.Although Onthophagus gibbulus,Onthophagus nuchicornis,Gymnopleurus mopsus,and Gymnopleurus flayellates have close genetic relationship,they were belonged to two functional groups and showed interspecific divergence in fecal disposal.
