海南岛蕨类植物的分类、区系地理与保育

摘要 "基于形态－地理学方法，通过野外调查，结合大量标本研究，在前人研究的基础上，对海南蕨类植物的分类进行了进一步修订;主要根据蕨类植物的现代地理分布，结合古生物学等有关资料，初步探讨了海南蕨类植物的区系性质与起源;根据IUCN2001年红色名录的等级和标准，对海南濒危蕨类植物的现状进行了初步评估，讨论了海南蕨类植物的受威胁原因，提出了有关保护的对策。主要结果如下： 1. 海南现有蕨类植物56科140属439个种及种下分类群（包括421种、15变种、2亚种和1变型），其中包括1个中国分布新记录和27个海南分布新记录，1新种――海南符藤蕨Teratophyllum hainanense;另有11个名称首次被处理为异名;澄清了海南假瘤蕨Phymatopteris hainanensis和圆顶假瘤蕨P. obtusa的模式问题，为滇桂三相蕨Ataxipteris dianguiensis、海南假瘤蕨P. hainanensis和浅杯鳞盖蕨Microlepia ampla指定了后选模式。 2. 海南蕨类区系具有以下特点：i. 以水龙骨科Polypodiaceae、金星蕨科Thelypteridaceae、铁角蕨科Aspleniaceae、叉蕨科Tectariaceae和观音座莲科Angiopteridaceae为表征科;ii. 明显的热带性质，科的97.5％、属的92.5％、种的83.6％为热带分布成分;iii. 很高的物种多样性与物种密度，但属内种系贫乏;iv. 与中南半岛的联系最为紧密，海南140个蕨类属中有136个与中南半岛共有，两地属的相似性系数达到87.2%;v. 海南蕨类区系就地起源于华夏古陆，起源时间可以追溯至早石炭世以前。 3. 海南439种蕨类（包括421种、15变种、2亚种和1变型）中，183种为常见蕨类，113种属于资料缺乏的种类（DD），47种属于近危（NT），53种属于易危（VU），37种属于濒危（EN），6种属于极危（CR）。海南的受威胁蕨类植物有96种，海南的绝大部分受威胁蕨类植物都生于保护区以内或得到有效保护的林区之内，已初步得到保护。导致海南96种蕨类受威胁的因素，除了植物本身的生物生态学特性和地理分布上的限制外，主要是人类活动的影响，特别是海南森林在上个世纪被大规模砍伐。为了保护这些受威胁植物，应加强保护区和林区的管理，实施就地保护，积极开展迁地保护和人工繁殖。 "

Exploring diarrhoea, enteral nutrition and intestinal microbial flora relationships in critically ill patients

Diarrhoea is a common complication observed in critically ill patients. Relationships between diarrhoea, enteral nutrition and aerobic intestinal microflora have been disconnectedly examined in this patient cohort. This research used a two-study, observational design to examine these associations. Higher diarrhoea incidence rates were observed when patients received enteral tube feeding, had abnormal serum blood results, received multiple medications and had aerobic microflora dysbiosis. Further, significant aerobic intestinal microflora changes were observed over time in patients who experienced diarrhoea. These results establish a platform for further work to improve the intestinal health of critically ill patients.

Biology Aotearoa : Unique Flora, Fauna and Fungi

As a large, isolated and relatively ancient landmass, New Zealand occupies a unique place in the biological world, with distinctive terrestrial biota and a high proportion of primitive endemic forms. Biology Aotearoa covers the origins, evolution and conservation of the New Zealand flora, fauna and fungi. Each chapter is written by specialists in the field, often working from different perspectives to build up a comprehensive picture. Topics include: the geological history of our land origins, and evolution of our plants, animals and fungi current status of rare and threatened species past, present and future management of native species the effect of human immigration on the native biota. Colour diagrams and photographs are used throughout the text. This book is suitable for all students of biology or ecology who wish to know about the unique nature of Aotearoa New Zealand and its context in the biological world.

Survey of weed flora and management relative to cropping practices in the north-eastern grain region of Australia

The main weeds and weed management practices undertaken in broad acre dryland cropping areas of north-eastern Australia have been identified. The information was collected in a comprehensive postal survey of both growers and agronomists from Dubbo in New South Wales (NSW) through to Clermont in central Queensland, where 237 surveys were returned. A very diverse weed flora of 105 weeds from 91 genera was identified for the three cropping zones within the region (central Queensland, southern Queensland and northern NSW). Twenty-three weeds were common to all cropping zones. The major common weeds were Sonchus oleraceus, Rapistrum rugosum, Echinochloa spp. and Urochloa panicoides. The main weeds were identified for both summer and winter fallows, and sorghum, wheat and chickpea crops for each of the zones, with some commonality as well as floral uniqueness recorded. More genera were recorded in the fallows than in crops, and those in summer fallows exceeded the number in winter. Across the region, weed management relied heavily on herbicides. In fallows, glyphosate and mixes with glyphosate were very common, although the importance of the glyphosate mix partner differed among the cropping zones. Use and importance of pre-emergence herbicides in-crop varied considerably among the zones. In wheat, more graminicides were used in northern NSW than in southern Queensland, and virtually none were used in central Queensland, reflecting the differences in winter grass weed flora across the region. Atrazine was the major herbicide used in sorghum, although metolachlor was also used predominantly in northern NSW. Fallow and inter-row cultivation were used more often in the southern areas of the region. Grazing of fallows was more prominent in northern NSW. High crop seeding rates were not commonly recorded indicating that growers are not using crop competition as a tool for weed management. Although many management practices were recorded overall, few growers were using integrated weed management, and herbicide resistance has been and continues to be an issue for the region.
