The biological characteristics of 58 crested ibis marked with color plastic rings have been observed for 9 years.Of all the marked birds,6 were captured and raised,2 were intentionally killed,another 2 were killed by natural enemy,still another 13 missed,and 28 survived in open fields.The birds raised and the ones in open fields respectively reproduced 13 and 17 birds.The birds mated naturally showed the avoidance of inbreeding,and began to reproduce at the age of 2.In addition,the birds mating relationship...

The biological characteristics of 58 crested ibis marked with color plastic rings have been observed for 9 years.Of all the marked birds,6 were captured and raised,2 were intentionally killed,another 2 were killed by natural enemy,still another 13 missed,and 28 survived in open fields.The birds raised and the ones in open fields respectively reproduced 13 and 17 birds.The birds mated naturally showed the avoidance of inbreeding,and began to reproduce at the age of 2.In addition,the birds mating relationship and the places to nest were relatively stable.Disease,natural enemy and forest denudation were primarily attributed to the birds extinction.

1987~1995年对58只20~25日龄的环志朱进行了生物学特性观察,其中捕回进行人工饲养3对,繁殖一代朱13只;人为杀害2只,天敌致死2只,因病死亡6只,失踪13只,野外存活28只,繁殖一代朱17只;朱在自然配对时有近亲繁殖的回避性,最早繁殖年龄为2岁,配偶与营巢地点有相对稳定性;疾病、天敌和林区破坏是朱濒临灭绝的主要因素。

The histological structure of the digestive system in a crested ibis died from an accident is observed.The results are as follows:The wall of the digestive tract consists of common 4 layer structure.Concentrated acinar glands are present in the mucusa of esophagus,which is characterized by vigorous secretion.Developed muscle layer is observed in proventricus and ventriculus which lack tunica muscularis.There are vigorous bundles of smooth muscle in the proper lamina and long villi of small intestine.No...

对一只意外死亡朱的消化系统各器官进行组织学观察,结果发现:消化管均具有一般的四层结构,但食管粘膜内有密集的泡状腺,分泌物丰富;腺胃和肌胃均未见粘膜肌,但肌层很发达;小肠绒毛较长,未见中央乳糜管构造,固有膜及绒毛内有丰富的平滑肌束;盲肠亦有短的绒毛,且淋巴组织发达,可形成淋巴小结。肝小叶间结缔组织少,小叶界线不清。

By studying the literature on the research and proteetion of crested ibis,the trend of research and protection of crested ibis were summaried systematically.At present,the numbers of crested ibis have reached about total 100 individuals distributed in Yang County and Beijing zoo,including about 40 wild crested ibis.Wild crested ibis can only be found in Yang County.Shaanxi Province,China.Finally,according to existing problem of crested Ibis protcction,the strategy has been...

By studying the literature on the research and proteetion of crested ibis,the trend of research and protection of crested ibis were summaried systematically.At present,the numbers of crested ibis have reached about total 100 individuals distributed in Yang County and Beijing zoo,including about 40 wild crested ibis.Wild crested ibis can only be found in Yang County.Shaanxi Province,China.Finally,according to existing problem of crested Ibis protcction,the strategy has been proposed.

目前,朱的种群总数量已突破100只,分布在洋县和北京动物园,其中包括野生种群40多只,野生朱仅分布在陕西省洋县境内。通过查阅朱研究和保护的有关文献,全面系统地综述了朱研究和保护的动态,并就存在的问题提出了相应的对策。
