| 1. | Chinese alligator ( alligator sinensis ) is an endemic endangered species in china 扬子鳄是一濒危物种,也是中国特有的珍稀爬行动物。 |
| 2. | The high polymorphism of mhc genes in chinese alligator would be of great benefit to gene tic conservation in the captive population of chinese alligator 本文的研究结果表明扬子鳄mhc基因的多态性较高,这对扬子鳄饲养种群的遗传保护将非常有利。 |
| 3. | The effect of temperature on the reproduction laying eggs of the chinese alligator in an artificial hibernant environment during a deep hibernation is reported in this paper 摘要本文报道了扬子鳄在人工越冬环境条件下,深眠期的温度值对越冬后繁殖的影响。 |
| 4. | On the basis of 6 years of research , this result showed that adult chinese alligators could lay eggs in the next year if the temperature 5 ~ 8 during a deep hibernation for them 6年的研究表明扬子鳄在深眠期的温度处在5 ~ 8时,扬子鳄越冬后能够成功繁殖产卵。 |
| 5. | In summer and autumn of 2003 , the author introduced target objective observation and scan sampling methods to research behaviors and time budgets of chinese alligator 2003年夏秋两季,采用扫描取样法和目标动物取样法,对饲养条件下扬子鳄的个体行为和活动时间分配进行了研究。 |
| 6. | Dna extraction from different specimens is the foundation of conservation genetics . it is difficult to extract total dna from tannage of chinese alligator with usual method 利用不同的实验材料提取适合研究的dna是保护遗传学研究的基础,而对于鞣制皮革,用常规的dna提取方法很难提到适合于研究的dna样品。 |
| 7. | This paper researched the behaviors and time budgets of captive - bred chinese alligator , and discussed the taxonomical status of chinese alligator ( alligator sinensis ) and the phylogeny of the reptiles based on the sequences of nt - 3 and bdnf genes 本论文对涉及饲养条件下夏秋两季扬子鳄的行为和活动时间分配进行了研究,同时基于nt - 3和bdnf基因部分序列探讨了扬子鳄的分类地位和爬行动物的系统发生。 |
| 8. | In order to study mhc genes of chinese a igator ( alligator sinensis ) , a pair of degenerate primers were used to amplify the segments of mhc class ii b genes from the genomic dna of chinese alligator . ten 166 bp ( one 160bp ) - long different nucleotide sequences , which were divided into two groups ( a , b ) , were obtained from cloning and sequencing 为了研究扬子鳄( alligatorsinensis )的mhc基因,本文利用一对简并引物扩增出扬子鳄mhc类b基因第二外元的部分片段,并对其进行了克隆及序列分析,结果得出10种不同序列,片段长166bp (其中一种为160bp ) 。 |
| 9. | By the end of 1995 china had set up 175 zoological gardens and zoological exhibition sites in public parks , 227 artificial breeding centers for wild animals , more than 60 large botanical gardens and 255 wild plant gene and cell banks to ensure the continuation of rare and endangered species of plants and animals , including the giant panda , chinese alligator , chinese sturgeon , white - flag dolphin , manchurian tiger , crested ibis , cathay silver fir , dovetree , cycas revoluta and camellia chrysantha tuyama 到1995年底,中国共建动物园和公园动物展区175个、各种野生动物繁殖中心(场) 227个,建立大型植物园60多个、野生植物引种保存基地255个,使大熊猫、扬子鳄、中华鲟、白暨豚、东北虎、朱? 、银杉、珙桐、苏铁、金花茶等珍稀濒危动植物得到保护。 |
| 10. | In this paper , total dna from tannage , tail skin , scales and the skin treated with salt were successfully extracted with an improved method for dna extraction . to verify the results , four pairs of primers , which were universal primers for 12s rrna gene , diagnostic primers of chinese alligator meat , microsatellite primers and rapd primer , were used to do pcr amplifications . some amplified fragments were sequenced , either 本文研究出一种改进的dna提取方法,成功地从扬子鳄鞣制皮革中提取了总dna ,同时对不同的组织标本如鳞片、盐腌生皮及尾尖皮等进行了dna提取:并利用12srrna基因扩增的通用引物、扬子鳄鉴定性引物、微卫星引物及rapd引物进行pcr扩增,且对部分pcr扩增结果进行测序,以检验提取效果。 |
