2006年12月,在广西西南部靖西县底定自然保护区考察时,采到一号雀形目鸟类标本,经鉴定为白眶鹟莺(Seicercus affinis),是广西鸟类新纪录。从2005年1月-2007年5月,在多次鸟类考察过程中都观察到野外活动的白眶鹟莺。在底定,白眶鹟莺通常多在常绿阔叶林的林下灌丛和山间农耕地周边的灌丛中活动,其栖息地海拔高度大致在500-700 m。全世界记录有2亚种,我国现已知仅有白眶鹟莺的一个亚种分布。该标本经鉴定为Seicercus affinis intermedius。文中还就白眶鹟莺在中国的分布情况作了讨论。标本现保存于广西大学动物科学技术学院动物标本室。 相似文献

中国柳莺属鸟类分类研究进展 总被引:2,自引:1,他引:1
柳莺属(Phylloscopus)是广泛分布于旧大陆地区的小型食虫鸟类,目前全世界已知66种,其中约50种见于亚洲。该属鸟类外部形态十分相近且同域分布种数较多,历来是鸟类分类学中的研究难点及热点。2003年贾陈喜等介绍了20世纪90年代以来发表的分布于我国的柳莺属鸟类新种及相关分类学变动,涉及3个新描述种和9个由亚种提升的种,共计30种26亚种。2003年以来关于柳莺属鸟类的分类学研究取得了许多新的成果,同时我国境内也发现了一些新的分布记录。综合最新的文献及分布资料,整理得知我国现有柳莺属鸟类41种31亚种,与2003年的状况相比已有较大的变化。主要表现在:新描述种方面,德国学者Martens等2008年描述了黄腹柳莺(P.affinis)种组中的一新种———华西柳莺(P.occisinensis);2010年瑞典学者Alstrm等报道在越南和老挝地区新发现的灰岩柳莺(P.calciatilis)已被证实在我国有分布;亚种提升为种方面,如日本柳莺(P.xanthodryas)自极北柳莺(P.borealis)中独立,冠纹柳莺(P.claudiae)和西南冠纹柳莺(P.reguloides)分开等;分类地位再评议方面,如灰头鹟莺(Seicercusxanthoschistos)实为灰头柳莺(P.xanthoschistos)等;新分布纪录方面,如欧柳莺(P.trochilus)在内蒙古达里诺尔湖地区发现确切记录等。现今对柳莺属鸟类分类学方面的研究已明显呈现出传统形态学、分子遗传学、声谱分析及野外鸣声回放实验等新老技术手段相整合,多方面多角度地阐述问题的局面。中国是世界柳莺属鸟种分布最多的国家(其中有9种仅在或主要于我国境内繁殖),但我国鸟类学者关于该属鸟类的研究工作并不多见。柳莺属鸟类在分类学和进化生物学等领域具有重要的研究价值,我国鸟类学工作者应当引起足够的重视和关注。 相似文献

中国柳莺属分类现状 总被引:2,自引:1,他引:1
柳莺属Phylloscopus一直是中国鸟类分类学中问题最多,研究最不完善的类群。在上世纪末的10年中,新增加了12种柳莺,包括新发现的3种和亚种被提升到种地位的9种。本文回顾和介绍了我国柳莺属分类研究概况,包括四川柳莺P.sichuanensis,海南柳莺P.hainanus和峨眉柳莺P.emeiensis3个新发现种。黄腰柳莺青藏亚种P.proregulus chloronotus和甘肃亚种P.p.kansuensis,黄腹柳莺P.affinis subaffinis亚种。黄腰柳莺青藏亚种P.proregulus chloronotus和甘肃亚种和P.c.sindianus亚种,黄眉柳莺P.inormatus humei亚种等的分类地位已由亚种升为种,但黑眉柳莺P.ricketti goodsoni亚种分类地位仍存在着争议,最后提出了目前我国柳莺属分类上尚存在的一些问题。 相似文献

峨眉山的旅游业近年发展很快,评估其鸟类的资源价值,是保护此自然资源、完善其旅游活动内容的现实需要。现将我们对此所作的尝试报告如下,供讨论和研究参考。1种类考查郑作新等(1963)记载峨眉山鸟类255种(以往记录的长尾鹩鹛或系斑翅鹩鹛之误,未计入)。其后,李桂垣(1982)补记16种。此外,我们还先后从当地采得鹌鹑Coturnix coturnix japonica(Ⅳ月,1000米),灰卷尾Dicrurus leucophaeus hopwoodi(Ⅶ,900),异色树莺Cettia flavolivacea dulcivox(Ⅵ—Ⅶ,2300—3000),白斑尾柳莺Phylloscopus davisoni disturbans(Ⅵ,3000)和黑尾蜡嘴雀Eophons… 相似文献

Twenty one species of ticks belonging to five genera of the family Ixodidae (Order Acari, sub-order Ixodida) - Amblyomma, Haemaphysalis, Hyalomma, Ixodes and Rhipicephalus (including the sub-genus Rhipicephalus (Boophilus)) - were collected from 1260 mammals, representing 29 species, 14 families and 6 orders, in four vegetation zones in Ghana during the period 1971-1978. Four other species were collected from humans in 1977. In all, eight species appeared to be new records for Ghana: Amblyomma tholloni Neumann; Dermacentor circumguttatus Neumann; Haemaphysalis houyi Nuttall & Warburton; Ixodes loveridgei Arthur; Ixodes oldi Nuttall; Ixodes vanidicus Schultze; Rhipicephalus complanatus Neumann; Rhipicephalus cuspidatus Neumann. The updated list of tick species in Ghana given here includes 41 species of ixodid ticks and four species of argasid ticks. Most species have been found in neighbouring regions of West Africa but 56 of the 121 different combinations of ixodid tick species and host species found in the collection described here have not apparently been reported before. The new combinations recorded here bring the total number of different combinations of ixodid tick species and mammalian host species now reported in Ghana to 151. The tick species found on wild mammals in Ghana mostly differed from those reported from domestic stock by other authors. The data showed that different tick species occurred in different vegetation zones and that most species displayed a pronounced preference for certain groups of related host species. Some tick species were found in the savanna feeding mainly on large bovids and/or suids; others were found in forests feeding mainly on small bovids, large rodents or small carnivores. 相似文献

退田还湖对洞庭湖湿地鸟类的影响 总被引:2,自引:0,他引:2
对洞庭湖湿地退田还湖前后湿地鸟类群落结构进行对比分析,阐述了湿地鸟类群落结构的变化趋势.洞庭湖湿地鸟类群落结构的变化表明,鸟类的数量在退田还湖后明显上升,与1992年洞庭湖湿地鸟类名录相比增加2目16科174种,尤其是雁鸭类、鹬鹆类、隼类和鸣禽的种数增加迅速.优势种退田还湖前只有32种,退田还湖后增加到74种.不同的湖区因生态环境异质性,退田还湖前后鸟类的群落结构也有差异.在记录的312种鸟类中,其中东洞庭湖分布有297种,南洞庭湖164种,西洞庭湖217种,共有鸟类138种,东洞庭湖特有鸟类较多(48种).经调查,退田还湖(垸)区鸟类群落结构变化更为明显,青山垸分布13目33科77种,西畔山洲垸分布8目20科37种,两垸共有鸟种33种,青山垸特有鸟类有41种,西畔山洲垸5种. 相似文献

During an investigation of the biodiversity and structure of parasite communities among native populations of the erythrinid fish Hoplias malabaricus (Characiformes) from 7 rivers in Brazil, the following monogenoidean (Dactylogyridae) species were found: Urocleidoides malabaricusi n. sp., Urocleidoides naris n. sp., Urocleidoides cuiabai n. sp., Urocleidoides brasiliensis n. sp., and Urocleidoides eremitus Kritsky, Thatcher, and Boeger, 1986. Specimens considered as a new genus of Dactylogyridae were also found. The new species are mainly distinguished from the other 14 species of Urocleidoides in the general morphology of their copulatory and anchors/bar complexes. These new species and the new dactylogyrid genus are described, as well as supplemental observations and new illustrations of U. eremitus are provided. The present findings expand the known geographical distribution of species of Urocleidoides to southeastern and midwestern Brazil. A high speciation of this genus in the tropics is hypothesized, and it is briefly discussed. 相似文献

In two short surveys of lignicolous, fruitbody-forming ascomycetes in Thailand and southern China, six species were found, of which five were new to science. Two fungi with affinity to the Dothideomycetes, one from Thailand and one from China, are described here in the new genus ALIQUANDOSTIPITE: and included in the new family Aliquandostipitaceae. Aliquandostipite khaoyaiensis was found in a tropical rain forest in Thailand and A. sunyatsenii in a small stream in southern China. Both new species are closely related based on morphological and molecular characteristics and with uncertain affinity to other taxa of the Euascomycetes based on phylogenetic analyses of SSU rDNA sequences. The distinguishing features of the new species are the presence of both sessile and stalked ascomata side by side on the substratum and the widest hyphae known from ascomycetes. 相似文献

The genus Lenormandia is composed of nine species from Australia and New Zealand. Some of the these are well known, but others are rare, obscure and ill-defined. We have examined material of all described species and found that they fall into two discrete groups that differ in apex morphology and position of reproductive structures. Plants of the first group, containing the type species L. spectabilis , have a cleft apex and reproductive structures produced directly on the blade surface, whereas those of the second group have a strongly inrolled apex and produce reproductive structures dorsally on small branchlets which arise either from the margins or the midrib. The groups were also found to form discrete clades on analysis of 18S rRNA sequences. All the members of the first group are endemic to Australia, whereas the second group, designated by the new genus name Adamsiella , contains two previously described New Zealand species and a single Australian representative. In addition, two new species are described in this group from New Zealand. Members of the closely related genus Lenormandiopsis were also examined and the type species, L. latifolia , was found to conform in apex morphology and position of reproductive structures to the genus Lenormandia. Accordingly Lenormandiopsis has been subsumed within Lenormandia. The remaining three members of the former genus Lenormandiopsis , however, were found to differ from both the type species and the genus Lenormandia and consequently have been transferred to the separate genus Geraldia , along with a new species from Geraldton, Western Australia which is designated as the type. 相似文献
