DESCRIPTION OF A KUBANOCHOERUS SKULL FROM TONGXIN, NINGXIA   总被引:1,自引:1,他引:0  
<正> A rich Middle Miocene mammalian fauna was discovered in a gully named Maerzuizi Gou, Tongxin County, Ningxia Hui Autonomous Region, in the winter of 1985. Among the fossils is a well preserved skull evidently belonging to Kubanochoerus. It is the third and, as far as we know, the best preserved of its kind so far in the world. A careful study of the skull has enabled us not only to review all the fossils previously discovered and assigned either to Listriodon or to Bunolistriodon in China, but also to clarify in certain degree the evolutionary trend and the classification of that particular group.  相似文献

<正> Rather abundant sample of Alloptox, including skulls, maxillae, mandibles and isolated teeth, was collected from the middle Miocene of Tongxin County, Ningxia Hui Autonomous Region during the two field seasons in 1985 and 1986, when reconnaissance and geological mapping of the middle Miocene in this region were conducted by a joint party of the Institute of Vertebrate Paleontology and Paleoanthropology, Academia Sinica (IVPP) and the Bureau of Geology, Ningxia Hui Autonomous Region. The specimens came from 18 localities pertaining to 9 levels in a sequence of middle Miocene fluviatile sediments with a thickness of ca. 200m. Except for the specimens assigned to Alloptox sp. from locality Taoziliang, all are recognized as Alloptox gobiensis. The present paper deals with only their dental morphology which is probably phylogenetically significant. Altogether 327 specimens of Alloptox gobiensis and 27 specimens of Alloptox sp. have been described. The text figures are drawn by the authors and Mrs. Yang Mingwan. All teeth are presented as left ones, the abbreviatd word "inv" is used under the figures of right teeth. All specimens are stored in IVPP under the inventory number V8822-V8839. The authors are much obliged to Prof. Qiu Zhanxiang for reading and correcting the English version of this paper.  相似文献

Aims Our objective was to explore the vegetation carbon storages and their variations in the broad-leaved forests in the alpine region of the Qinghai-Xizang Plateau that includes Qinghai Province and Xizang Autonomous Region. Methods Based on forest resource inventory data and field sampling, this paper studied the carbon storage, its sequestration rate, and the potentials in the broad-leaved forests in the alpine region of the Qinghai-Xizang Plateau. Important findings The vegetation carbon storage in the broad-leaved forest accounted for 310.70 Tg in 2011, with the highest value in the broad-leaved mixed forest and the lowest in Populus forest among the six broad-leaved forests that include Quercus, Betula, Populus, other hard broad-leaved species, other soft broad-leaved species, and the broadleaved mixed forest. The carbon density of the broad-leaved forest was 89.04 Mg•hm2, with the highest value in other hard broad-leaved species forest and the lowest in other soft broad-leaved species forest. The carbon storage and carbon density in different layers of the forests followed a sequence of overstory layer > understory layer > litter layer > grass layer > dead wood layer, which all increased with forest age. In addition, the carbon storage of broad-leaved forest increased from 304.26 Tg in 2001 to 310.70 Tg in 2011. The mean annual carbon sequestration and its rate were 0.64 Tg•a1 and 0.19 Mg•hm2•a1, respectively. The maximum and minimum of the carbon sequestration rate were respectively found in other soft broad-leaved species forest and other hard broad-leaved species forest, with the highest value in the mature forest and the lowest in the young forest. Moreover, the carbon sequestration potential in the tree layer of broad-leaved forest reached 19.09 Mg•hm2 in 2011, with the highest value found in Quercus forest and the lowest in Betula forest. The carbon storage increased gradually during three inventory periods, indicating that the broad-leaved forest was well protected to maintain a healthy growth by the forest protection project of Qinghai Province and Xizang Autonomous Region.  相似文献

<正> From the same beds in the east of Tongxin County, Ningxia Hui Autonomous Region, where the large Kubanochoerous had been found (Qiu et al., 1988), some Bunolistriodon jaws and teeth were recently discovered. These specimens have been assigned to B. intermedius. The new material enables us to discuss in more detail the possible relationships between the so-called intermediate "Listriodon" and lophodont listriodons.  相似文献

One hundred and two isolates of Chaetomium spp. have been identified from 2563 soil samples collected from permanent pasture at Nappan, Nova Scotia. Chaetomium umbonatum was the Chaetomium species most commonly isolated. Fifty-six of the Chaetomium isolates were grown in the laboratory and the cultures examined for the production of toxic metabolites. The culture filtrates of 12, and extracts of mycelium of 18, of these isolates inhibited bacterial growth. Chetomin was detected in nine mycelium extracts and isolated from four of the mycelium extracts. Chaetoglobosins were isolated from three mycelium extracts.  相似文献

During the last 50y, the carcinogenic mycotoxin sterigmatocystin (ST) has been reported in several phylogenetically and phenotypically different genera: Aschersonia, Aspergillus, Bipolaris, Botryotrichum, Chaetomium, Emericella, Eurotium, Farrowia, Fusarium, Humicola, Moelleriella, Monocillium and Podospora. We have reexamined all available strains of the original producers, in addition to ex type and further strains of each species reported to produce ST and the biosynthetically derived aflatoxins. We also screened strains of all available species in Penicillium and Aspergillus for ST and aflatoxin. Six new ST producing fungi were discovered: Aspergillus asperescens, Aspergillus aureolatus, Aspergillus eburneocremeus, Aspergillus protuberus, Aspergillus tardus, and Penicillium inflatum and one new aflatoxin producer: Aspergillus togoensis (=Stilbothamnium togoense). ST was confirmed in 23 Emericella, four Aspergillus, five Chaetomium, one Botryotrichum and one Humicola species grown on a selection of secondary metabolite inducing media, and using multiple detection methods: HPLC-UV/Vis DAD, - HRMS and - MS/MS. The immediate precursor for aflatoxin, O-methylsterigmatocystin was found in Chaetomium cellulolyticum, Chaetomium longicolleum, Chaetomium malaysiense and Chaetomium virescens, but aflatoxin was not detected from any Chaetomium species. In all 55 species, representing more than 11 clades throughout the Pezizomycotina, can be reliably claimed to be ST producers and 13 of these can also produce aflatoxins. It is not known yet whether the ST/aflatoxin pathway has been developed independently 11 times, or is the result of partial horizontal gene transfer.  相似文献

Summary It was shown that Chaetomium was isolated from four types of soil; Cinebar, Ephrata, Milville, and quartz sand, more frequently when using alcohol agar as the growth medium than it (Chaetomium) was isolated from these soils when using either Czepak's-Dox agar or peptone-dextrose agar plus rose bengal and streptomycin. This isolation method proved to be one which permits identification of the Chaetomium species without further culturing.This paper is based on work performed under United States Atomic Energy Commission Contract AT (45-1)-1830.  相似文献

During the camera-trapping survey at Wanghuannan, Erlonghe and Hongxia Forest Farms in the Liupan Mountain National Nature Reserve in Guyuan City, Ningxia Hui Autonomous Region, 49 independent detections of Reeve’s muntjac, Muntiacus reevesi were captured by eight infrared-triggered camera-traps with 274 photographs and 12 video clips from July, 2017 to August, 2018. The Reeve’s muntjac is an endemic species of China and mainly distributed in south China, such as Jiangxi, Guangdong, Guangxi, Hunan, Hubei, Yunnan, Sichuan, Guizhou and Taiwan Provinces, and also distributed in Shaanxi and Gansu Provinces adjacent to Ningxia Hui Autonomous Region. This species was for the first time recorded in Ningxia Hui Autonomous Region, so its distribution range has been expanded in China. This discovery has enriched the distribution information of Reeve’s muntjac. This discovery will also play an important role in the study of biodiversity and species integrity in the area of Liupan Mountain.  相似文献

甘肃仓鼠的分类地位   总被引:1,自引:0,他引:1  
自1928年Allen发表采自甘肃卓尼的甘肃仓鼠(Cansumys canus)以来,对其分类地位的争论就没有停止,不同学者从形态学和生态学方面研究得出了不同的结论。为了确认Allen所命名的甘肃仓鼠的分类地位,本研究利用形态性状和遗传性状,比较研究了甘肃、宁夏标本(包括模式产地标本)与华北、东北大仓鼠标本共计169只。结果显示:甘肃、宁夏地区标本身体及头骨量度与大仓鼠指名亚种、东北亚种间大多无显著性差异;地理分布连续,其间无隔离,也无地理重叠;生态特征与华北、东北的大仓鼠相似;基于线粒体DNA D-loop区序列的遗传变异分析表明,甘肃、宁夏地区种群与大仓鼠东北亚种种群关系较大仓鼠东北亚种种群与指名亚种种群关系更近;单倍型演化关系显示,指名亚种种群和东北亚种种群分别独立地由甘肃种群单倍型衍生而来,并且三个种群单倍型之间的分歧较浅,没有形成种上的分歧程度。据此,甘肃、宁夏地区“甘肃仓鼠”应为大仓鼠甘肃亚种[Cricetulus triton canus(Allen),1928]。  相似文献
