On the other hand,there has been so far no mapping method and software that can be used to map dominant-recessive markers obtained from F2 population of lepidopteran species.To resolve this problem,two-point and three-point maximum likelihood methods for mapping dominant-recessive markers using F2 population of this type of species were developed in this paper.At,the same time:we also gave a general method for constructing the gene linkage map of this type of species using F2 population.
另外,目前还没有任何方法和软件可以用杂交F2群体来作图鳞翅目类昆虫,如家蚕等连锁图谱,为了解决这一问题,本文发展了用F2群体作图这类昆虫连锁图谱的两点和三点极大似然法,同时还给出了大群体作图形态基因连锁图谱的一般方法。

This study deals with butterfly diversity and conservation of rare as well as insect fauna species in Baishuijiang Natural Reserve in Gansu Province. The research includes field investigation, observation at certain time and places, captive breeding in experimental area etc. Butterfly species diversity in Baishuijiang Natural Reserve and variation regulation of butterfly diversity in different areas are studied. The relationof butterfly diversity with environmental factors such as vegetation destruction, human disturbance are strenthened in Bifeng Gully. The biology of two rare butterfly species is studied. Meanwhile, this study deals with insect α-diversity and β-diversity in Baishuijiang Natural Reserve and inquire into the mechanisms of ecological control by protecting and recovering vegetation. The research includes field capture with sweeping net, light trap, transect investigation.

The results showed that fishes of 11 orders, 18 families, and 46 species were represented in Changshu section of the Yangtze river. After the season, the total catch per unit effort increased sharply in the section; the dominant species were mainly commercial fishes such as Coilia ectenes, Mugil cephalus and Parabramis pekinensis and the annual change of dominant species was not obvious. The CPUE of Coilia ectenes had risen up and the trend of resource deterioration had been kept within limits. The caught rate of pintsized and juvenile fish rose markedly. The Margalef's index and Wilhm's index had an evident tendency of rising, while McNaughton's index and Pielou's index waved slightly.
研究结果表明:4~6月间常熟江段出现的鱼、虾、蟹类渔获物共有11目、18科、46种;春禁后,该江段总CPUE显著增加;优势种更替不明显,历年以刀鲚、鲻鱼、长春鳊等经济鱼类为主;刀鲚CPUE有所回升,资源衰退受到遏制;小型鱼类、幼鱼在渔获物中的比例明显上升; Margalef物种丰富度指数、Wilhm改进指数呈明显上升趋势,均匀度指数J′、优势度数Dw在窄幅范围波动。

The results showed that the total dissoluble proteins hands of 8% and 10% gel were 91 and 97, respectively, and the seed salt soluble proteins bands of 10% gel were 69; All of the five alfalfa species have their own characteristic bands, which are different in number, distribution, width, and concentration; Among three methods, the five species' seed dissoluble protein fingerprints of 10% gel' bands is relatively more, which genetic diversity scattered in A, B and C regions, and can be repeated in different experiments. So it's the best fingerprint. The fingerprints of the seed dissoluble proteins and seed salt soluble proteins of five species are unanimous, which showed that: the hybrid has the nearest genetic distance with Medico go sativa cv.
结果显示:5/个种10%和8%凝胶电泳的种子可溶性蛋白总带数分别为97和91, 10%凝胶电泳的种子盐溶蛋白共有69条谱带;5种苜蓿在种子可溶性蛋白和盐溶蛋白电泳图上都具有各自的特征谱带,谱带数目、位置、宽窄和颜色深浅都存在明显的差异;10%凝胶的可溶性蛋白指纹图谱谱带数目相对较多,种间遗传差异在A、B、C区均有分布,谱带的重复性好,是鉴别种的最好图谱。5种苜蓿种子可溶性蛋白和盐溶蛋白指纹图谱一致,表明杂交种和敖汉苜蓿的谱带相似性最大。

The rate of repetitive sequences was 2.55% and no SINEs, LINEs, LTR anti-transcription elements or DNA transposon elements were found, although one11 microsatellite was found. 2 In the P1 promotor region, sequence homology between the Tibetan sheep and mouflon, goat, cattle and European bison was 99.7%, 94.2%, 85.9% and 86.5%, respectively, while that for exon 1A was 99.0%, 97.0%, 92.7% and 94.6%, respectively. 3 The molecular phylogenetic tree among these species, constructed by the neighborhood joining method based on the sequences of no-coding region of the GHR genes, placed the two Bovinae species on one branch and the three Caprinae species on the other.
