重庆市蝶类新记录

This paper reports 13 newly recorded butterflies found in Chongqing,including 6 species of skippers,6 species of blues,and 1 species of metalmark.The sum of Chongqing butterfly species increases to 472 species.Among the taxa mentioned in the present work,Chrysozephyrus fujiokai Koiwaya and Howarthia hishikawai Koiwaya were not listed in the 2513 species of butterflies in the comprehensive catalogue "Systematic Butterfly Names of the World" by Shou,Chou and Li(2005)

枯叶蛱蝶中华亚种基因组Survey分析

通过第二代高通量测序手段对枯叶蝶的基因组进行Survey分析,研究枯叶蛱蝶的起源、进化及适应性,明确适合该物种全基因组深度测序和组装策略.通过低覆盖度测序预测枯叶蝶基因组大小,并利用生物信息学方法估计该种的杂合率、重复序列和GC含量等基因组信息.结果显示:(1)枯叶蛱蝶中华亚种(Kallima inachus chinensis Swinhoe)的基因组大小估计为545.05 Mb, GC含量为35.24%,测序深度为52×;(2)除略小于Maniola jurtina (614.74 Mb)和翠袖锯眼蝶(Elymnia shypermnestra)(566.93 Mb)外,明显大于其余蛱蝶的基因组;(3)K-mer分析(K=17)结果显示枯叶蝶基因组具有明显的杂合峰,杂合率为1.22%,重复序列比例为48.03%.
