  5. 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，這些研究主要限於生態學、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，並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。
