蜉寄蝇属Phorocera隶属于双翅目Diptera寄蝇科Tachinidae追寄蝇业科Exoristinae追寄蝇族Exoristini,一般寄生于鳞翅口毒蛾科,夜蛾科和尺蛾科的幼虫;主要分布于古北区和新北区.该属区别于追寄蝇族Exoristini 其它属的特征为:眼后鬃列后方具黑毛,复眼具淡黄色长毛,单眼鬃位于前单眼后方,背中鬃3+3,翅内鬃0+3,腹部背板具心鬃.本文系统研究了中国蜉寄蝇属的4个已知种,勺肛蜉寄蝇P.assinilis,锥肛蜉寄蝇P.grandis,直条蜉寄蝇P.normalis和昏暗蜉寄蝇P.obscura;并首次描述了直条蜉寄蝇的雄性和采自我国辽宁本溪的1新种,辽宁蜉寄蝇Phorocera liaoningensis sp.nov.;编制了古北区本属6种雄性检索表.新种区别于近缘种勺肛蜉寄蝇的特征为:第4腹板后缘钝圆,中脉心角至中肘横脉的距离略长于心角至翅后缘的距离,雄性肛尾叶后面观端半部均匀变窄.     

The Apionidae (Coleoptera: Curculionoidea) of New Caledonia, genus Caledonapion Wanat

The New Caledonian endemic weevil genus Caledonapion is revised, with one new species, C . assimile , described. Diagnoses, a key and distribution maps are provided for both species of the genus. An association of Caledonapion with the plant genus Hedycarya (Monimiaceae) is suggested from field observations.     

Fishes of the family Ipnopidae (Teleostei: Aulopiformes) collected on the Brazilian continental slope between 11° and 23° S

A collection of fishes from the Brazilian continental slope between 11° and 23° S obtained through trawling revealed nine species of Ipnopidae. Bathypterois bigelowi and Bathytyphlops marionae represent first records from the south-western Atlantic Ocean and Bathypterois grallator is reported off Brazil for the first time. Four species have their distribution extended in Brazilian waters: Bathypterois phenax , Bathypterois quadrifilis , Bathypterois viridensis and Ipnops murrayi . An identification key of Ipnopidae species from the south-western Atlantic Ocean is included.     

New and reassessed species of Strobilanthes (Acanthaceae) in the flora of China

Several problems in Strobilanthes Blume (Acanthaceae: Ruelliae) are clarified as a result of collaboration between Chinese and western botanists. Examination of pollen has permitted clear delimitation of four morphologically similar species, Strobilanthes szechuanica (Batalin) J. R. I. Wood & Y. F. Deng, S. labordei H. Lév., S. wakasana Wakasugi & Naruhashi and S. wilsonii J. R. I. Wood & Y. F. Deng, the latter described for the first time in this paper, although first collected more than a hundred years ago. A key is provided to help distinguish these species. The globose, echinulate pollen found in several species from China and Japan and assigned to the genus Championella by Bremekamp is shown by SEM photography to be distinct from other pollen hitherto regarded as the same. Three new species, S. abbreviata Y. F. Deng & J. R. I. Wood, S. lihengiae Y. F. Deng & J. R. I. Wood and S. vallicola Y. F. Deng & J. R. I. Wood are described. S. austinii C. B. Clarke ex W. W. Sm. is lectotypified to show that it is conspecific with S. lamiifolia (Nees) T. Anderson, a species demonstrating trans-Himalayan links. New combinations are made for four species as the authors recognize only a single genus, Strobilanthes within the Strobilanthinae as defined by Bremekamp. S. gongshanensis Tsui and S. aenobarba W. W. Sm. are shown to be only varieties of S. inflata T. Anderson. Illustrations are provided for all new species.  © 2006 The Linnean Society of London, Botanical Journal of the Linnean Society , 2006, 150 , 369–390.     

中国小香菇属新记录种

报道了小香菇属2个中国新记录种,即耳状小香菇Lentinellus auricula和海狸色小香菇 Lentinellus castoreus,并确认粗毛小香菇 Lentinellus vulpinus在中国的分布。对上述3种进行了详尽的形态学描述并提供特征线条图,编写中国小香菇属Lentinellus已知种分种检索表。     

我国珍稀濒危植物保护红线的划定

本文依据《国家生态保护红线——生态功能基线划定技术指南(试行)》原则和植物保护的具体情况, 探讨了我国珍稀濒危植物保护红线划定的原则与方法。研究选取《国家重点保护野生植物名录》中收录的所有物种作为研究对象。将其定义为红线保护植物, 其中的I级保护植物定义为红线关键植物, 并基于文献资料及标本记录等数据建立了我国植物的属性数据库和地理分布数据库。在GIS支持下, 以建立的数据库为基础研究了我国红线保护植物的地理分布特征; 基于保护生物学理论, 结合我国自然保护区的就地保护现状进行了分析和评价; 以热点地区和GAP分析为理论基础, 在其分布地中识别具有代表性的热点区域以及不同属性植物分布的重点区域, 进而结合土地利用和人类干扰因素, 划定我国珍稀濒危植物生境整体保护的红线。通过在全国尺度上的分析, 得出我国珍稀濒危植物的整体保护红线面积为71.63万km², 占陆域国土面积的7.45%。植物生境保护红线划定的原则、方法和划定方案的研究对于更准确地划定生态安全预警红线具有重要意义, 同时可以为我国国土生态安全格局的构建提供依据。     

微生物降解芘过程中的关键细菌

【目的】探究在渤海沉积物中参与降解芘的关键细菌及他们之间潜在的相互关系。【方法】构建以芘为唯一碳源的微宇宙培养体系驯化来自渤海的表层沉积物,借助Illumina Hiseq 2500获取驯化过程中的细菌群落组成,基于CCLasso算法及相对丰度数据预测细菌之间的相互作用关系以构建微生物生态网络。【结果】30 d后芘的降解率为(67.07±2.37)%,细菌群落结构也发生了明显改变:Alphaproteobacteria、Flavobacteriia、Planctomycetia等的相对丰度明显增加,而Deltaproteobacteria、Anaerolineae及Spirochaetes等则明显减少。本研究获得一个由29个点143条边构成的微生物生态网络。分类已知的属中,Erythrobacter及Planctomyces等拥有较高的点度中心度。较强的互作关系发生在Erythrobacter与Flavobacteriaceae、Alphaproteobacteria中的未知属之间。【结论】在芘的微生物降解过程中,关键细菌之间存在紧密互作。Erythrobacter为关键细菌的代表属。
