NOTES ON THE CORTICIACEAE OF NORTHERN CHINA

<正> 98 species of Corticiaceae s.l.are reported from Changbai shah forestreserve in Northern China.Phlebia pellucida Hjortst.& Ryv.is described as new.The newcombinations Amylosporomyces subasperisporus,Boidinia propingua,and B.peroxydata are pro-posed.The genus Boidinia is discussed and a key is given to accepted species.Many rarespecies are reported such as Amylocorticium laceratum,Ceraceomyces sulphurinus,Hyphodontiaaltaica,Laeticorticium ussuricum,Lobulicium occultum,Sistotrema athcloiides and Tubulicrinissceptiferus.The flora is boral and most of the species have a wide distribution in the Nor-thern coniferous zone.In a previous paper species of Polyporaceae were reported from Northern China(Ryvarden et al.,1986).Most of the species were collected during a short expedition tothe Changbai Shun forest reserve in the Jilin Province.This paper reports the species ofCorticiaceae (s.lato) from the same expedition.There are duplicates of all species bothin Oslo University Herbarium and the Herbarium of Mycologicum,Academia Sinica(HMAS)the Institute of Microbiology in Beijing.The knowledge of the Corticiaceae of China is veryfragmentary and many of the names indicated in previous reports are now replacedby othernames,and the identification of the collections in many cases are dubious.Thus,we havenot tried to establish how many of these species which previously have not been reportedfrom China.Such a list would be of little interest since very few has collected Corticiacritically in recent times,and the flora is still more or less unknown with regard to thisgroup of fungi.The following list must therefore be regarded as a first contribution tolist the Corticiaceae of China based on the same species concepts and names as currentlyused in Europe and North America,see Eriksson et al.(1976—84)Jiilich and Stalpers(1984),Gilbertson (1974).List of collections all from 11—17 Sept.1983.Nos.21315—21407/21696—21814.Jilin Prov.,Changbai Shah,Forest Reserve,Hangcong gou,750 m.a.s.l.Nos,21408—21603.JilinProv.,Changbai Shah,Forest Reserve,Huang Song Pu,1200 m.a.s.l.Nos.21619—21695.Jilin Prov.,Changbai Shun,Forest Reserve,Bai Shun Station,1100m.a.s.l.     

金屏山地区斑翅蝗科—新属新种(直翅目:蝗总科)

本文记述四川省凉山彝族自治州金屏山地区斑翅蝗科壮蝗属Ochyracris Zheng新属及红胫壮蝗Ochyracris rufutibialis Zheng新种。该新属近似于赤翅蝗属CelesSaussure,主要区别为:头侧窝短三角形,在头顶顶端相距较远;后翅基部淡黄色;后足胫节红色。 模式种:红胫壮蝗Ochyracris rufutibialis Zheng新种。     

山猪群体钙调蛋白酶抑制蛋白基因遗传变异研究

目的：研究猪钙调蛋白酶抑制蛋白（CAST）基因在山猪群体的遗传变异情况,为山猪肉质研究奠定基础。方法：应用PCR-SSCP技术和测序方法检测山猪及其杂种猪CAST基因的遗传多态性,并与其他品种猪相应序列进行比较。结果：用pCT1引物在山猪及其杂种群体中检测到2个多态位点（A,B）,用pCT2引物检测到3个多态位点（C,D,E）;序列分析表明,C和E位点共同拥有6处变异。结论：通过与其他猪品种比较,发现山猪的CASTMsp基因型分布与梅山猪的基因型分布完全一样,而与国外品种猪的基因型分布差异明显。     

Uniform growth trends among central Asian low- and high-elevation juniper tree sites

We present an analysis of 28 juniper tree-ring sites sampled over the last decades by several research teams in the Tien Shan and Karakorum mountains of western central Asia. Ring-width chronologies were developed on a site-by-site basis, using a detrending technique designed to retain low-frequency climate variations. Site chronologies were grouped according to their distance from the upper timberline in the Tien Shan (∼3,400 m a.s.l.) and Karakorum (∼4,000 m), and low- and high-elevation composite chronologies combining data from both mountain systems developed. Comparison of these elevational subsets revealed significant coherence (r = 0.72) over the 1438–1995 common period, which is inconsistent with the concept of differing environmental signals captured in tree-ring data along elevational gradients. It is hypothesized that the uniform growth behavior in central Asian juniper trees has been forced by solar radiation variations controlled via cloud cover changes, but verification of this assumption requires further fieldwork. The high-elevation composite chronology was further compared with existing temperature reconstructions from the Karakorum and Tien Shan, and long-term trend differences discussed. We concluded that the extent of warmth during medieval times cannot be precisely estimated based on ring-width data currently available.

新疆洛浦山普拉古墓人骨的种系问题

新疆洛浦山普拉古墓地的古代居民在体质形态特点上应是接近长颅欧洲人种地中海东支类型而不是具有“大蒙古人种大部分特征,但也有欧罗巴人种一些较明显特征”的混血类型。
