We studied the molecular phylogeography and geographical differentiation of Edwards rat Leopoldamys edwardsi(Thomas,1882),a species with wide distribution ranges in the southern China including Hainan Island,on the basis of mitochondrial cytochrome b(Cytb,1140 bp)and cytochrome c oxidase subunit I(CO1,1524 bp)genes.Among 39 haplotypes,three lineages(L1,L2,and L3)were formed consistently in maximum likelihood and the Bayesian phylogenetic inference trees as well as median-joining network analyses with high Kimura-2-parameter divergences(5.2 – 9.3%).

陕西佛坪国家级自然保护区是我国大熊猫(Ailuropoda melanoleuca)分布较多的保护区之一。前人的研究发现，该保护区的大熊猫在当年10 月至次年2 月基本都以巴山木竹(Bashania faberi)竹叶为食。竹叶中除含有丰富的营养物质外，还含有大量的植物次生代谢产物。黄酮类化合物(flavonoids)是竹叶中一种重要的植物次生代谢产物，具有抗氧化、清除自由基等多种生物学功能。

全球大熊猫(Ailuropoda melanoleuca)约有2240 只，其中约1/6 为圈养种群.大多数的圈养单位地处低山平坝区，大熊猫的食物主要靠人为选择和供应，这在一定程度上影响了大熊猫的营养与健康.为了给圈养单位提供合理的营养和饲养方案，本研究选用成都大熊猫繁育研究基地6 只(3♀3♂)健康的成年大熊猫，进行为期2 年(2013.01-2014.12)的饲养实验和消化实验，比较研究圈养雌
Identification of shrews is very difficult mainly due to tiny body,high similarities in morphology and controversial taxonomy.In this study,mitochondrial cytochrome oxidase subunit I(COI)was used as D
