| 1 | 建设当代植物标本馆体系的探索——以上海辰山植物标本馆(CSH)为例显示文摘21世纪已进入第三个十年,世界范围内的维管植物系统发育研究工作的大框架已基本完成,属级、种级和群体的系统发育学研究正在深入。但是,自地球进入人类世以来,大片原生森林遭到破坏,地表植被发生了深刻变化,多个植物种群萎缩甚至濒于灭绝,这使得野外第一手材料的采集变得越来越困难。此外,国内外对于植物资源的保护意识在不断加强,这虽有利于植物保育,但也给正常的科研交流造成了一定程度的障碍。经过4个多世纪的发展与积累,全球标本馆馆藏标本已达3.97亿份,在分子生物学技术不断迭代和完善的背景下,这些系统性收集与科学馆藏的标本正在成为开展属级、种级和群体系统发育研究的重要科研材料。因此,当下探讨当代植物标本馆体系建设如何适应学科发展的需求恰逢其时。该文通过回顾世界与中国植物标本馆概况,结合上海辰山植物标本馆(CSH)建设的经验,提出6个方面的思考:(1)革新标本管理者的理念,转变“等人来”的被动式服务习惯,通过各种渠道吸引业内外人士来访,提升标本馆的人气。(2)规范合理规划标本馆功能区域,为标本提供安全的馆藏环境,为来访者营造舒适的研究氛围。(3)秉承开放共享的理念不断提升馆藏物数字化覆盖率,注重数据标准化,保证数据的科学有效性。(4)合理利用信息技术替代重复性工作岗位,让标本馆工作更富成效和吸引力。(5)按照国家级平台要求不断提升馆藏物收藏多样性和馆藏环境,时刻为能在国家级或国际平台展示馆藏资源做好准备。(6)积极响应社会发展需求,让标本馆成为集信息咨询、资源服务、培训教育于一体的多元化机构,成为国家或地方的植物资源科技服务平台。 | 葛斌杰 陈彬 钟鑫 陈建平 李晓晨 | 2022 | 广西植物2022,42,S01: | 0 |
| 2 | Two new species from Sulawesi and Borneo facilitate phylogeny and taxonomic revision of Engelhardia(Juglandaceae)显示文摘Engelhardia,a genus of Juglandaceae(the walnut family),is endemic to tropical and subtropical Asia.The rich Cenozoic fossil records and distinctive morphological characters of the living plants have been used to explore the evolutionary history and geographic distribution of Juglandaceae.However,the taxonomy of this genus has been suffered from a lack of in-depth investigation and good specimens across its distribution ranges.Species delimitation of Engelhardia was defined with seven species in 2020,but detailed information on the circumscription of the species still remains poorly understood.In this study,two new species are described from Sulawesi and Borneo,Engelhardia anminiana and E.borneensis.We also revised and reconstructed the phylogeny within Engelhardia using morphological,molecular(plastid and ribosomal),and distribution data.We sampled 787 individuals in 80 populations,and all the samples were genotyped using plastid regions,trnS-trnG,rps16,trnL-trnF,psbA-trnH,and rpl32-trnL;one ribosomal region,nuclear ribosomal internal transcribed spacer(nrITS).The all datasets were used to reconstruct the phylogenetic relationships.Then,the molecular analyses were combined for 738 sheets of specimens with 15 morphological characteristics to further explore the morphological clusters of Engelhardia.Cluster analysis using morphological data confirmed the delimitation of nine Engelhardia species.Also,phylogenetic analysis based on molecular data(i.e.,plastid and ribosomal)supported the monophyly of Engelhardia and generated phylogenetic trees that included E.fenzelii,E.roxburghiana,E.borneensis,E.hainanensis,E.anminiana,E.serrata,E.villosa,E.apoensis and the varieties of E.spicata(i.e.,E.spicata var.spicata,E.spicata var.rigida,E.spicata var.aceriflora,and E.spicata var.colebrookeana).Our comprehensive taxonomic revision of Engelhardia will provide an insight into understanding the plant diversity in tropical and subtropical Asia. | Hong-Hu Meng Can-Yu Zhang Shook Ling Low Lang Li Jian-Yong Shen Nurainas Yu Zhang Pei-Han Huang Shi-Shun Zhou Yun-Hong Tan Jie Li | 2022 | Plant Diversity2022,44,6: | 0 |
