<正>Dear Editor,Shortly after initiating the"Physical Anthropological Research on Han Chinese"research project,we applied uniform sampling methods as well as methods and instruments of measurement to obtain a complete set of measurements of physical anthropological indicators among Han populations across China.Among these measurements,body stature was a key indicator.Currently,there should be reliable 相似文献

There is some discrepancy in the classification of different species of Hylopetes, particularly regarding systematic status of H. electilis and H. phayrei and their relationship to other species. In the present study, for the first time we have brought together six of the nine Hylopetes species and performed statistical analysis of 14 measurable cranial variables, analyzing in total 89 specimens,including H. electilis, H. alboniger, H. phayrei, H. lepidus, H. spadiceus, and H. nigripes. Both univariate and multivariate analysis results indicate that H. electilis can not only be obviously distinguished from H. phayrei, but also clearly differs from the other four Hylopetes species. These results sustain the contention that H. electilis is neither a synonym nor subspecies of H. phayrei, but should be considered a distinct and valid species. Subsequently, a straightforward discussion on the biogeography of Hylopetes in southeastern Asia gives further insight into the differentiation and variety of species belonging to this genus. 相似文献

不同间作枣园害虫的群落结构与动态 总被引:11,自引:0,他引:11
对5种不同间作枣园的害虫群落结构特征进行了研究,结果表明,在不同的间作枣园中,害虫的科、种与个体数是各不相同的,其多样性、均匀度和Berger-Parker指数也有明显差异(p<0.05)。间作牧草或保留杂草的枣园,害虫的科与种以及多样性和均匀度明显(p<0.05)大于间作小麦、大豆和单作枣园,而个体数和Berger-Parker指数则显著(p<0.05)小于单作枣园。枣园害虫个体数的时序动态随季节交替而有明显(p<0.05)的变化,4~8月份害虫的个体数明显(p<0.05)大于3月份、9~10月份。在枣园间作作物、牧草或者适当保留一定数量的杂草,不仅能够充分有效地利用枣园的空间和自然资源,而且增加了生物的多样性,改善了枣园的生态环境,同时提高了有害生物相互制约的能力和枣园单位面积的纯收入。 相似文献

Jk (kidd) blood group antigens are carried by the urea transporter UT-B[1,2]. The Jknull phenotype, lack-ing urea permeability in erythrocytes[3,4], has a very low frequency in all populations except Polynesians and Finns[5]. In Japan, only 14 individuals with Jk (a-b-) phenotype were identified from 638460 screened donor’s blood samples using the 2 mol/L urea solution hemolysis test[6]. The frequency of Jknull is 0.27% in Polynesian, about 0.03% in Finland[7], and extremely rare in Fran… 相似文献

Copyright by Science in China Press 2005 Primary hepatocarcinoma is one of the most fre-quent digestive-tract cancers, particularly in China. The incidence and death rate of primary hepatocarci-noma in China is the highest in the world, with about 1100 thousands people dying from primary hepatocar-cinoma per year[1]. Although the chemotherapeutic agents are the main therapeutic approach for hepato- carcinoma, they are relatively ineffective and result in many toxic and side effects. Accordin… 相似文献

Cucumber (Cucumis sativus L. 2n = 2x = 14), thatbelongs to Cucurbitaceae family, is one of majorvegetables with a planting area second to that of to-mato in the world[1]. Due to its economical importanceplant breeders and geneticists have paid much atten-tion to the genetic study on this important vegetablecrop, but the research progress in cucumber is muchless than that in tomato. In 1990, Pierce[2] reviewed allthe reported genes of cucumber that had been geneti-cally analyzed since the 1930… 相似文献
