  • That means genetic diversity in crested ibises can be sustained , and on the base the populations " adaptive capacity and evolutionary potential should be promoted . in this way , the rare bird will be protected more successfully
    根據譜系而在繁殖酉己付時盡可能地避免近交,將增進個體間的基因交流,使種群的遺傳多樣性得以維持,并有可能提高其生存能力與進化潛力,最終達到更好地保護這一稀世珍禽的目的。
  • Crested ibis ( nipponia nippori ) , a kind of peculiar wading bird in east asians facing its extinction because of humanbeings " economic activities . seven crested ibises found at yong county shaanxi province in 1981 were the all wild individuals left in the world then . to protect this rare bird , scholars have carried out a great deal of researches on it in many areas . however , till now , studies is mainly confined to some areas such as ecology and morphology , little was done in the area of molecular biology . phenomina such as disable individuals increasing and adults " producing ability decreasing occurred more frequent in recent years . these badly affected the existence and development of this species . so , getting the information about crested ibis " gene and genetic diversity through studies at molecular level and setting up scientific producing and protecting projections are becoming urgent tasks
    為保護這?瀕危鳥類,我國學者對朱?展開了多方位的研究。然而迄今為止,這些研究主要限于生態學、形態學等方面,分子生物學領域則很少涉及。近年來朱?種群頻繁出現諸如殘疾幼鳥增多、成鳥繁殖力下降等問題,已嚴重影響到種群的生存與發展,因此,從分子水平對朱?進行研究,了解其基因信息和遺傳多樣性,并確定個體之間的親緣關系,從而制定科學、合理的繁殖計劃與保護對策,已成為當務之急。
  • Similarity coefficient and genetic distances between two arbitrary individuals were caculated according to the data of experiments , the pedigree was constructed by two means ( they were upgma and parsimony ) , and genetic diversity was discussedbased on selecting the best conditions of pcr with opg and opa primers from operon company , we obtained 163 bands using 24 random primers . in other words , 163 sites in crested ibis " genome were detected . the bands from 23 primers showed polymorphism . minimurn of polymorphic ratio was 0 , maximum was 85 . 71 % , and average was 48 . 99 % . in the population which was composed by 37 individuals , most of genetic distances between two arbitrary individuals were less than 0 . 1 . the results showed that the degree of similarity among crested ibises was high while genetic diversity in the population was low accordingly
    我們在對operon公司opg系列和opa系列引物進行優化篩選的基礎上,用24條隨機引物共擴增出163條譜帶,即檢測了朱?基因組中的163個位點,其中23條引物的擴增結果具有多態性;譜帶的多態比率最小為0 ,最大為85 . 71 ,平均為48 . 99 ;在由37只朱?組成的種群中,任意兩個個體之間的遺傳距離絕大多數在0 . 1以下。這些結果表明,目前朱?個體間的相似程度很高,種群的遺傳多樣性水平較低。
