| 1 | Genetic Diversity and Population Structure for the Conservation of Giant Spiny Frog(Quasipaa spinosa)Using Microsatellite Loci and Mitochondrial DNA显示文摘The giant spiny frog(Quasipaa spinosa) is an endangered species with a relatively small distribution limited to southern China and Northern Vietnam. This species is becoming increasingly threatened because of over-exploitation and habitat degradation. This study provides data on the genetic diversity and population genetic structure of the giant spiny frog to facilitate the further development of effective conservation recommendations for this economically important but threatened species. We examined 10 species-specific microsatellite loci and Cyt b genes(562 bp) collected from 13 wild populations across the entire range of this species. Results of 10 microsatellite loci analysis showed a generally high level of genetic diversity. Moreover, the genetic differentiation among all 12 populations was moderate to large(overall F_(ST) = 0.1057). A total of 51 haplotypes were identified for Cyt b, which suggests high haplotype nucleotide diversities. Phylogeographic and population structure analyses using both DNA markers suggested that the wild giant spiny frog can be divided into four distinct major clades, i.e., Northern Vietnam, Western China, Central China, and Eastern China. The clades with significant genetic divergence are reproductively isolated, as evidenced by a high number of private alleles and strong incidence of failed amplification in microsatellite loci. Our research, coupled with other studies, suggests that Q. spinosa might be a species complex within which no detectable morphological variation has been revealed. The four phylogenetic clades and some subclades with distinct geographical distribution should be regarded as independent management units for conservation purposes. | Danna YU Rongquan ZHENG Qinfang LU Guang YANG Yao FU Yun ZHANG | 2016 | Asian Herpetological Research2016，7，2： | 5 |
| 2 | Overview of Researches on Social Capital,Human Capital and Social Integration of New Generation Migrant Workers显示文摘With urbanization and socio-economic development,new generation migrant workers play an increasingly important role in urban construction. However,for a long time,their social integration situation in inflow places is not ideal. Academic circle has done a lot of researches,but no effective strategy is so far put forward. Through analysis of domestic and foreign researches,it is found that social capital and human capital have an important influence on social integration of new generation migrant workers. This paper takes this as starting point,combines characteristics of new generation migrant workers,and overviews theories and empirical researches of domestic and foreign famous scholars,to explore the relationship between social capital and human capital and social integration of new generation migrant workers. | Wenjing LUAN Honghong LU Yulin TONG Danna LU | 2013 | Asian Agricultural Research2013，5，3： | 2 |
| 3 | Epidemiological,Clinical and Serological Characteristics of Children with Coronavirus Disease 2019 in Wuhan:A Single-centered,Retrospective Study显示文摘Dear Editor,In December 2019,SARS-Co V-2 was first detected in the samples obtained from three adult patients who suffered from an unknown viral pneumonia in Wuhan(Li et al.2020).This unknown viral pneumonia is further named as coronavirus disease 2019(COVID-19)by the World Health Organization. | Dan Luo Zhi Xia Heng Li Danna Tu Ting Wang Wei Zhang Lu Peng Wenfu Yi Sai Zhang Junhua Shu Hui Xu Yong Li Buyun Shi Chengjiao Huang Wen Tang Shuna Xiao Xiaolan Shu Yan Liu Yuan Zhang Shan Guo Zhi Yu Baoxiang Wang Yuan Gao Qinxue Hu Hanzhong Wang Xiaohui Song Hong Mei Xiaoqin Zhou Zhenhua Zheng | 2020 | Virologica Sinica2020，35，6： | 0 |
