乔旭  杨贵生  张乐  邢璞  李敏 《动物学杂志》2011,46(2):126-136
2009年4月至2010年3月对内蒙古乌海市的鸟类区系及群落结构进行了调查研究。共记录到鸟类132种,隶属于17目37科。其中留鸟26种,夏候鸟71种,旅鸟27种,冬候鸟8种。繁殖鸟有97种,其中古北界鸟类有83种,占繁殖鸟类种数的85.6%。研究发现不同季节、不同生境中的鸟类群落特征差异较大。春季的鸟类多样性指数和均匀度指数均最高;湿地的鸟类多样性指数最高。本文基于研究结果提出了对乌海市鸟类及其生存环境的保护建议。  相似文献

漫谈中国古鸟类研究   总被引:1,自引:0,他引:1  
侯连海 《化石》2000,(2):23-24
借世界第五届古鸟类及进化会议即将在北京召开之机 ,向广大古生物爱好者 ,特别是目前众多热爱古鸟类化石的读者 ,简要介绍我国研究古鸟类的历史及主要成果、它们在鸟类演化中的意义 ,或许是有益的。中国鸟类化石的研究始于1895年 ,但在1932年以前均为外国学者所报道 ,实际是一种半殖民地性质的掠夺 ,他们采集的化石全带出国外了 ,1932年首次由我国古脊椎动物学奠基人、中国科学院学部委员(院士)、著名古生物学家杨钟健先生报道北京周口店一白肩雕头骨化石 ,其后他又多次报道鸵鸟蛋化石。新中国建立后 ,我国古鸟类的研究才获得…  相似文献

天津地区主要资源鸟类调查   总被引:11,自引:0,他引:11  
天津地区主要资源鸟类同芦苇变化有着密切的关系,由于芦苇地及其芦苇收购数量的变化,认为芦苇是影响本地区主要资源鸟类资源很重要的因素之一。 主要资源鸟类在本地区有明显的季节性和地域性,因此在迁徙期鸟类的数量比较多,特别是鸭科一类鸟类,调查主要资源鸟类共有34种,分别隶属于二目、二科。  相似文献

四川白坡山自然保护区冬季鸟类群落调查   总被引:2,自引:0,他引:2  
杨彪  冉江洪  蔡国  曾宗永 《四川动物》2006,25(3):509-515
2003年12月对四川白坡山自然保护区的鸟类群落的种类和数量进行了调查,实际发现鸟类151种,结合历史文献23种,保护区鸟类共有174种,隶属于12目41科。保护区有国家级重点保护鸟类14种,四川省保护鸟类2种,我国特有鸟类5种。保护区鸟类区系以东洋界成分为主。利用多样性指数分析了不同群落的鸟类多样性,结果表明:地处1300~2600 m的中山云南松及其混交林群落鸟类多样性最高,原因是该群落中生境类型丰富多样。  相似文献

动物贸易是生物多样性丧失的重要原因,在物种的繁殖期进行捕捉和贸易对种群更是不利。为分析和评价贵阳本地鸟类在繁殖期间的生存现状和保护需求,于2014年3—6月调查了贵阳市油榨街花鸟市场上被交易的鸟类。共记录到114种当地鸟类,种数超过贵阳当地鸟类总数的50%,其中7种为保护物种。用于"斗鸟"的灰喉鸦雀Paradoxornis alphonsianus被交易的数量最高,画眉Garrulax canornus、红嘴相思鸟Leiothrix lutea、暗绿绣眼鸟Zosterops japonicas、红尾水鸲Rhyacornis fuliginosus和黄喉鹀Emberiza elegans等数量次之。接近80%的陆栖或半陆栖的鸟类及其雏鸟在繁殖期间都面临着很高的被捕捉风险。除了开展人工繁育,还建议开展野生鸟类的性别识别和性比研究,以减少野生雌鸟的损失和评价鸟类物种保护的优先性,同时加大宣传,将笼养鸟类者发展为支持鸟类研究和保护的重要力量。  相似文献

Summary Serum immunoglobulin concentration and skin reactivity to at least three recall antigens were determined in 210 patients with chronic myeloid leukemia (CML). Immunoglobulin concentration was normal in the great majority of the patients. Skin tests were negative in 50 of 210 cases (24%). No relationship could be demonstrated between skin reactivity, age, time since diagnosis, WBC, lymphocyte count, and splenectomy. Prior antileukemic therapy was a major factor in determining the response to skin tests.S. Tura (Chairman) and M.

Summary A prospective randomized trial compared the administration of intrapleural plus intravenous Corynebacterium parvum (C. parvum) versus placebo in patients with resected Stage I and Stage II non-small cell bronchogenic carcinoma. Treatment consisted of 7 mg C. parvum injected into the pleural space and 7 mg C. parvum intravenously once between days 6 and 12 postoperatively and 7 mg intravenously every 3rd month during the 1st year. Intrapleural administration of 35 cc of saline served as the placebo and the flush after intrapleural C. parvum.Of the 303 patients entered into this study, 286 were evaluable, with an average follow-up time of 3.5 years. More complications, especially fever, were observed in patients receiving C. parvum. A fever greater than 38 °C was observed in 9% of the patients assigned to placebo and 76% of the patients assigned to C. parvum. There was no significant difference between the treatments with respect to disease-free interval or survival.M. Kaufmann, J. Stjernswärd**, A.

Summary A detailed revision of the zoogonid subfamily Lepidophyllinae is presented, using morphological characters discussed in an earlier paper. Twelve genera and 50 species are treated in detail with keys and cladograms to genera and species. The genera and species covered are: Lepidophyllum steenstrupi, L. appyi, L. armatum, L. brachycladium, L. cameroni, L. pleuronectini, L. pyriforme, L. schantaricum, Urinatrema hispidum, U. hirudinacea, Panopula cavernossa, P. bridgeri, P. spinosa, Limnoderetrema minutum (Manter, 1954) [formerly Deretrema] n.g. (in freshwater fishes; genital pore at oral sucker or pharynx level), n. comb., Brachyenteron peristedioni, B. acropomatis, B. campbelli, B. doederleiniae, B. magnibursatum, B. parexocoeti, B. pycnorganum, Steganodermatoides kergeleni, S. agassizi, S. allocytti, S. maceri, Neosteganoderma glandulosum, N. infundibulum, Proctophantastes abyssorum, P. gillissi, Deretrema (Deretrema) fusillus, D. (D.) cholaeum, D. (D.) pacificum, D. (Spinoderetrema) plotosi, D. (S.) acutum, D. (S.) fellis, D. (S.) ovale, D.(S.) sebastodis, D. (Luxitrema) philippinensis, D. plagiorchis, Pseudochetosoma salmonicola, Overstreetia sodwanaensis, Steganoderma (Steganoderma) formosum, S. (S.) atherinae, S. (Lecithostaphylus) retroflexum, S. (L.) depauperati (Yamaguti, 1970) n. comb., S. (L.) hemirhamphi, S. (L.) nitens, S. (L.) parexocoeti, S. macrophallos, S. oviformis. Most zoogonids were found to exhibit some level of predilection for a particular piscine host group, but little general information on the zoogeography of the group was discovered. Ultrastructural evidence is presented suggesting that the membranous egg-capsule of the zoogonines shows vestiges of the three layers of a normal tanned egg-shell.  相似文献
