A taxonomic study on the genus Harpapion Voss, 1966 from China (Coleoptera,Apionidae)

Harpapion safranum sp. n. and Harpapion borisi sp. n. are described and figured. Harpapion vietnamense (Korotyaev, 1987) is recorded as new for China. The genitalia andterminalia of H. considerandum, H. coelebs andH. vietnamense are redescribed and redrawn. The diagnostic characters of Harpapion are defined. A key to the known species of the genus Harpapion from China is provided. Affinities with the genus Flavopodapion Korotyaev, 1987 are discussed.     

Three new species of the genus Probles F?rster (Hymenoptera,Ichneumonidae, Tersilochinae) from?South Korea

Three closely related species of the genus Probles Förster, P. fulgida sp. n., P. korusa sp. n. and P. rukora sp. n., belong to the subgenus Euporizon Horstmann and differ from other Palearctic species of the genus by a combination of long and apically weakly sinuate ovipositor and short temple. These three species are assigned to a newly designated fulgida species-group, and a portion of the key for identification of this species-group is provided. Based on the shape of the ovipositor apex, the fulgida species-group resemble members of the subgenus Microdiaparsis Horstmann but are distinct in having a much shorter temple.     

Heptageniidae (Insecta,Ephemeroptera) of Thailand

Nine genera and twenty-two species of heptageniid mayflies from Thailand are defined in this present work as well as one suggested further subgenus, Compsoneuria (Siamoneuria) kovaci (species “incertae sedis”) including some particular characters. Taxonomic remarks, diagnoses, line drawings of key characters, distribution, habitat and biological data, and a larval key to the genera and species are provided. The chorionic eggs of eight genera and eight species were observed and shown using a scanning electron microscope.     

Aegilops (Poaceae) in Italy: taxonomy,geographical distribution,ecology, vulnerability and conservation

ABSTRACT

Aegilops L. includes wild species from which, over millennia, man has cultivated forms of Triticum L. Ten species of Aegilops occur in Italy. Three species are allochthonous and eight out of ten species are recorded in the Apulia region. Five out of the ten species have been included in Red Lists. Each taxon is presented and discussed, citing old and new sites of occurrence, by examining specimens from many different herbaria, and describing their ecology and habitats, according to the Directive 92/43 EEC. A new taxonomic key, for the identification of all Aegilops species growing in Italy, is provided. The occurrence of Aegilops caudata L., A. peregrina (Hack. in J. Fraser) Maire & Weiller and A. speltoides Tausch in Italy is doubtful.     

Molecular identity,morphology and taxonomy of the Rhynchospio glutaea complex with a key to Rhynchospio species (Annelida,Spionidae)

Rhynchospio glutaea (Ehlers, 1897 Ehlers, E. 1897. Polychaeten. Ergebnisse der Hamburger Magalhaensischen Sammelreise 1892/93. L. Friederichsen & Co., Hamburg, Germany. [Google Scholar]), Rhynchospio arenincola Hartman, 1936 Hartman, O. 1936. New species of Spionidae (Annelida Polychaeta) from the coast of California. University of California Publications in Zoology 41, 45–52. [Google Scholar] and Rhynchospio arenincola asiatica Chlebovitsch, 1959 Chlebovitsch, V.V. 1959. Species of Polychaeta worms from the Kurile Islands, which are new or recorded for the first time in the USSR fauna. Zoologichesky Zhurnal 38, 167–181. [Google Scholar], originally described from Strait of Magellan, California, and South Kurile Islands respectively, appear similar to each other in adult morphology. These species and subspecies have been considered by some authors as subjective synonyms and are here referred to as members of the R. glutaea complex. Sequence data of four gene fragments (2465 bp in total) of the mitochondrial 16S rDNA, nuclear 18S and 28S rDNA, and Histone 3 have shown that R. glutaea complex individuals from the South West Atlantic (Argentina), North East Pacific (British Columbia and Oregon) and North West Pacific (South Korea) were genetically distant and not conspecific. These data also indicate that R. arenincola from North America and R. aff. asiatica from South Korea are more closely related to each other, and both are closer to R. glutaea from South America than to R. nhatrangi from Vietnam: nhatrangi (glutaea (arenincola-aff. asiatica)). Adults of the R. glutaea complex are hermaphrodites and the arrangement of gametes is suggested to be a crucial reproductive character for distinguishing these species. Based on this character, two species of the complex are apparent in the North West Pacific: R. asiatica Chlebovitsch, 1959 Chlebovitsch, V.V. 1959. Species of Polychaeta worms from the Kurile Islands, which are new or recorded for the first time in the USSR fauna. Zoologichesky Zhurnal 38, 167–181. [Google Scholar] stat. nov. from the Kurile Islands (not analysed here) and an unnamed species from the mainland coast of Asia (here referred to as R. aff. asiatica). Adult morphology of R. asiatica stat. nov. is briefly described and illustrated. The lectotype and the type locality of the species on Iturup Is. are established for the first time. An identification key is provided to the 10 currently recognized Rhynchospio species.     

基于文献计量分析的珊瑚礁研究现状与热点

珊瑚礁生态系统在全球海洋生态中扮演着重要角色,它为热带海洋动物提供栖息地,为人类提供食物药物资源,是全球生产力最高的生态系统之一。为了解当前国内外珊瑚相关研究的现状与热点,利用文献计量的方法统计分析了珊瑚的相关研究。文章分别以WEB OF SCIENCE数据库和中国期刊全文数据库(CNKI)中期刊论文为国际和国内的数据源,从文献计量的角度出发,利用Excel按年份统计论文的发文数量,通过Bibexcel得出高频词共词矩阵,并用Ucinet和Netdraw得出共词网络可视化图谱。利用SPSS进行聚类分析,分别将国内外相关研究分为四大类,分析珊瑚相关研究趋势与热点。研究表明:①国际与国内的珊瑚研究除个别年份有所回落,均基本成逐年上升趋势,大致于20世纪90年代开始进入成熟阶段,但国内的研究略迟于国际;②国际上对珊瑚的研究更倾向于探究珊瑚礁退化的原因,而国内则以提高珊瑚礁的造礁能力为研究热点;③通过共词分析得出,国际研究高频词中的coral reefs,corals,climate change,sedimentation,一定程度上也可视为研究热点;④通过聚类分析,国内外的珊瑚研究有一定的相似性,主要集中在珊瑚礁生态系统、影响珊瑚的环境因子、气候因子等几个方面,但国内外研究又各有侧重。总结得出,有关珊瑚、珊瑚礁研究在国内外均以珊瑚礁为重点,近年来和未来珊瑚礁研究注重于珊瑚礁修复或帮助珊瑚礁生态系统自行恢复。
