云南菜食花植物资源与食花文化调查

为了摸清云南省菜食花植物资源种类、自然分布与食用地区、食用方法等土著知识,对云南省16个地州102个县(市)农贸市场、地方菜餐馆、民间食花者进行了访问调查,对菜食花植物进行了植物学实地鉴定。调查到云南省菜食花植物140种,隶属52科108属,其中木本植物82种,草本植物58种;人工栽培76种,人工驯化栽培14种,野生资源50种。首次报道苦绳(Dregea sinensis Hemsl.)、云南山楂(Crataegus scabrifolia(Franch.)Rehder)、滇海水仙花(Primula pseudodenticulata Pax)、长毛黄葵(Abelmoschus crinitus Wall.)、尖叶美容杜鹃(Rhododendron caloplytum var.openshawianum(Rehd.et Wils.)Chamb.)、大纽子花(Vallaris indecora(Baill.)Tsiang et P.T.Li)、大花虫豆(Cajanus grandiflorus(Benth.ex Baker)Maesen Vaniot der Maesen)、须弥葛(Pueraria wallichii DC.)、白花灯笼(Clerodendrum fortunatum L.)等9种植物的花可以做菜食用。菜食花植物自然分布区与食用地区并非完全重叠,食用地区一般分布有该植物,而分布有该植物的地区不一定食用;食用种类具有从南向北逐渐减少的特点,与食花植物丰富度和少数民族有一定的关系;食花习俗具有一定的民族性,主要体现食花的种类和烹饪口味上。不同菜食花食用的部位不同,烹饪方式也呈多样化。本文针对食用花传统文化的消失与野生菜食花资源的开发利用提出了相关建议。     

Promoting regional sustainability by eco-province construction in China: A critical assessment

The regional level has been recognized as a good scale for implementing actions towards sustainable development (SD). An important pathway to improve regional sustainability is to locally carry out long-term ecological planning. In order to reduce environmental impacts from fast economic growth, several eastern provinces of China began Ecological Province Construction (EPC) at the end of 1990s. This paper presented a case for analyzing the progress of EPC in China via both qualitative and quantitative methods. We studied Shandong Eco-province Construction (SEPC) and evaluated its outcomes with its pre-set indicators in 2003–2010. A further evaluation with eco-efficiency and de-linking indices was conducted. The results indicated the pre-set indicators could not effectively reflect of the ecological province construction. It was recommended to introduce an evaluated framework combined with eco-efficiency and de-linking indices to indicate ecological planning at the regional scale.     

Response of instream animal communities to a short-term extreme event and to longer-term cumulative impacts in a strategic water resource area,South Africa

Disturbance plays an integral part in generating heterogeneity required for ecosystem persistence, but the increased amplitude and duration of disturbances linked to drivers of global change could result in ecosystem shifts or collapse. Biomonitoring over time provides insights into trajectories of ecosystem change. The responses of two instream animal taxa to two contrasting disturbance events, a major flood event and the long-term cumulative effects of land-use changes, were assessed in 1999–2012 by quantifying variation and change in abundance of functional groups based on flow rate sensitivity, water quality and metrics of ecological condition. All metrics recovered to pre-flood conditions within seven months after the flood event. Similarly, cumulative impacts of land use effected significant decreases in some but not all metrics. Indices that did not change, including SASS total score and ASPT, were the result of insufficient consideration of the decrease in the abundance of sensitive taxa specifically, and the abundance of all taxa in general. The decrease in abundance of sensitive taxa could signal imminent collapse in certain metrics. Evidence is also provided for a shift in the structure of fish assemblages linked to the decrease and loss of taxa sensitive to ecosystem degradation caused by the longer-term impacts of land-use change.

山东苔藓植物新记录

该研究通过对采自山东的苔藓植物标本进行鉴定,首次发现裂齿藓[ Dichodontium pellucidum (Hedw.) Schimp.]和粗疣藓[ Fauriella tenuis (Mitt.) Cardot]在山东的分布,这也是昂氏藓科(Aongstroemiaceae)裂齿藓属( Dichodontium Schimp.)和粗疣藓属( Fauriella Besch.)的苔藓植物在山东的首次发现。文中还详细描述了裂齿藓和粗疣藓的形态特征,绘制了墨线图,并进行了相应的讨论。     

山西省健康人群的肠道菌群组成特征

目的探索山西省健康人群的肠道菌群组成特征及性别和年龄对肠道菌群组成的影响。方法应用16S rRNA基因测序技术,对山西省99名健康个体的粪便细菌DNA进行测序分析。结果山西省健康人群的肠道菌群在属水平分为两个集群,相对丰度最高的分别是拟杆菌属和普氏菌属;在区分这两个集群中,拟杆菌属与普氏菌属的曲线下面积（AUC）分别是0.97、1.00。男性组与女性组的物种丰富度（richness）和多样性（diversity）差异都无统计学意义（均P>0.05）,基于Bray-Curtis距离的主坐标分析（PCoA）图显示两组人群的样本分布没有明显分离（相似性分析：r=-0.0296,P>0.05）,LEfSe分析显示与性别分组有关的细菌很少。30-39岁、40-49岁和50-59岁三组人群的物种丰富度和多样性差异都无统计学意义（均P>0.05）,基于Bray-Curtis距离的PCoA图显示三组人群的样本分布没有明显分离（相似性分析：r=0.0109,P>0.05）,LEfSe分析显示几乎没有与年龄分组有关的细菌。结论山西省健康人群的肠道菌群更倾向分为两种肠型（拟杆菌型和普氏菌型）。性别对肠道菌群组成可能没有显著影响,30-59岁人群的肠道菌群组成比较稳定

山东平邑盆地古新世孢粉组合及其古气候意义

本文对山东平邑盆地卞桥镇国泰庄西ZK101井卞桥组二段的21块井壁岩芯样品进行分析,在其中5块样品中发现了大量保存较好的孢粉和一些淡水藻类化石,总计60属2亚属63种及部分未定种。据此建立了一个孢粉组合,即Pterisisporites-Ephedripites-Ulmaceae组合。该组合以凤尾蕨科和麻黄科花粉占优势,榆科有一定含量为其主要特征,并通过对一些重要分子的地质时代分布及与邻区相关孢粉组合进行对比,确定了其时代为古新世,同时讨论了该孢粉植物群所反映的古气候特点。
