云南省香格里拉大峡谷藏族神山在自然保护中的意义

位于云南省西北部迪庆藏族自治州境内的香格里拉大峡谷拥有独特的自然人文景观和丰富的生物多样性。藏族作为当地最重要的原住民族,他们的文化对当地的自然环境具有重要的影响。为了解藏族传统文化中的神山崇拜对香格里拉大峡谷地区自然环境的影响,本文应用民族生态学、植物生态学和文化人类学的研究方法,结合文献资料的分析,对香格里拉大峡谷的藏族神山进行了调查和研究,并对处于不同保护状态下（神山与非神山）的两个典型植物群落即高山松(Pinus densata)群落和云南黄果冷杉(Abies ernestii var. salouenensis)群落进行了比较。结果显示,在相同的样地面积内（20 m×20 m）,神山植物群落在物种数量（20,14）和群落盖度（100%,85%）方面都明显高于非神山植物群落（11,2;70%,60%）。结合入户调查资料,发现广泛分布于香格里拉大峡谷的藏族神山构成了一个“自下而上”的乡土保护体系,它不仅在保护生物多样性、维护当地脆弱的生态环境等方面发挥着重要的作用,而且还可以提供多种非林产品,实现多种生态功能。文章探讨了发挥乡土保护体系的保护功效及应用传统文化知识以促进自然保护的重要性,建议应当尊重和保护原住民的传统文化,发掘其中优秀的自然保护知识和经验,引导其发挥更加有效的自然保护功能,使民族传统保护体系成为现代自然保护体系的有力补充。

Changing attitudes in nature conservation: the Nature Conservancy and Nature Conservancy Council

An official organization responsible for ecological research and nature conservation was formed in 1949. This paper traces its development and vicissitudes, first as an independent Nature Conservancy, then as a part of the Natural Environment Research Council, and finally as the Nature Conservancy Council. Much has been achieved: ecology is now a household word; there is a strong voluntary tide for nature conservation in the country; and there have been notable achievements in practical conservation. But the dangers to nature in Britain have proved to be much greater than anticipated.     

Characterization of sequence variability in nucleosome core histone folds

The three-helix, approximately 65-residue histone fold domain is the most structurally conserved part of the core histones H2A, H2B, H3, and H4. However, it evinces a notable degree of sequence variation within and between histone classes. We used two approaches to characterize sequence variation in these histone folds, toward elucidating their structure/function relationships and evolution. On the one hand we asked how much of the sequence variation seen in structure-based alignments of the folds maintains physicochemical properties at a position, and on the other, whether conservation correlates to structural importance, as measured by the number of residue-to-residue contacts a position makes. Strong physicochemical conservation or correlation of conservation to contacts would support the idea that functional constraints, rather than genetic drift, determines the observed range of variants at a given position. We used an 11-state table of physicochemical properties to classify each position in the core histone fold (CHF) alignments, and a public website (http://www.ebi.ac.uk/thornton-srv/databases/cgi-bin/valdar/scorecons_server.pl) to score conservation. We found that, depending on histone class, from 38 to 77% of CHF positions are maximally conserved physicochemically, and that for H2B, H3, and H4 the degree to which a position is conserved correlates positively to the number of contacts made by the residue at that position in the crystal structure of the nucleosome core particle. We also examined the correlation between conservation and the type of contact (e.g., inter- or intrachain, histone-histone, or histone-DNA, etc.). For H2B, H3, and H4 we found a positive correlation between conservation and number of interchain protein contacts. No such correlation or statistical significance was found for DNA or intrachain contacts. This suggests that variations in the CHF sequences could be functionally constrained by requirements to make sufficient interchain histone contacts. We also suggest that inventory of histone residue variants can augment functional studies of histones. An example is presented for histone H3.     

黄淮海地区湿地系统生物多样性保护格局构建

以黄淮海地区为研究对象,首先分析了区域现有湿地保护状况,再基于湿地类型、保护状况和目标保护物种分布,综合考虑GDP、人口密度等社会经济因素,以湿地生物多样性保护为目标,运用系统保护规划的理论和方法,以Marxan作为空间优化模型,进行多目标的湿地系统保护预案设计,构建区域湿地不同保护水平的保护空缺和不可替代性格局,确定合理的湿地系统保护格局。研究结果表明:现有的湿地保护体系仅覆盖了区域17%左右的湿地,尚有许多重要生境游离于现有保护区系统外。为完善黄淮海地区湿地保护体系,需要对黄海海区域内28个保护区进行功能区划调整或者保护等级提升,并在山东(5个县)和河北(4个县),河南、江苏和安徽(各3个县),北京和天津(各1个县)等20个县市内建立新的保护区,与现有湿地保护系统有机整合,最终形成一个黄淮海地区湿地生物保护网络合理格局。结果表明:同其他相关研究方法对比,系统保护规划方法在区域大尺度生物多样性保护方面更具有意义;同时也表明该方法在中国的应用前景广阔。     

The conservation of declining butterfly populations in Britain and Europe: priorities, problems and successes

The status, ecology and conservation of butterflies in Europe and Britain are reviewed, as a background to the National Trust's past and future contribution to British conservation. Britain has a poor butterfly fauna by European standards, the main areas of endemism and species richness being in the Alps and southern Europe. To date, the main declines among European butterfly populations have occurred across central-northern Europe, with slightly higher extinction rates in mainland countries than in Britain. The main causes of decline are biotope destruction, the loss of certain species' habitats within surviving semi-natural biotopes due to changed land management, and a failure by several species to track the patches of their habitat that are still being generated in modern fragmented landscapes. Until recently, most conservation programmes failed to take account of the latter two factors, resulting in many local extinctions of rare butterfly species even in conservation areas. Recent measures have been much more successful; many were first tested on National Trust properties.

Conserving Orthoptera in the wild: lessons from Trimerotropis infantilis (Oedipodinae)

Orthopteran species are increasingly threatened with extinction in the wild. I review the state of orthopteran conservation in the wild, focusing on unique challenges facing these efforts. To provide a basis for discussion, I first review conservation efforts for Trimerotropis infantilis, the Zayante bandwinged grasshopper, which was the first orthopteran given official protection under the U.S. Endangered Species Act. I then address the principal challenges for orthopteran conservation. Successful conservation of Orthoptera in the wild will require motivation for conservation action, availability of basic biological information, and development of applied management programmes.     

The key elements of a comprehensive global mammal conservation strategy

A global strategy is necessary to achieve the level of coordination, synergy and therefore optimization of resources to achieve the broad goal of conserving mammals worldwide. Key elements for the development of such a strategy include: an institutional subject that owns the strategy; broad conservation goals, quantitative targets derived from them and appropriate indicators; data on the distribution of species, their threats, the cost-effectiveness of conservation actions; and a set of methods for the identification of conservation priorities. Previous global mammal research investigated phylogeny, extinction risk, and the species and areas that should be regarded as global conservation priorities. This theme issue presents new key elements: an updated Red List Index, a new list of evolutionarily distinct and globally endangered species, new high-resolution mammal distribution models, a global connectivity analysis and scenarios of future mammal distribution based on climate and land-cover change. Area prioritization schemes account for mammalian phylogeny, governance and cost-benefit of measures to abate habitat loss. Three discussion papers lay the foundations for the development of a global unifying mammal conservation strategy, which should not be further deterred by the knowledge gaps still existing.     

Population-specific migratory strategies of Twite Linaria flavirostris in Western Europe

Migratory connectivity describes the extent to which different individuals from specific breeding populations use similar non-breeding sites, with important consequences for the demography and population structure of birds. We used mark-recapture data from the EUring data bank to describe the non-breeding range of Twite Linaria flavirostris within Western Europe. We quantified the strength of migratory connectivity across all European breeding populations, and for the British and continental breeding populations separately. Twite from different parts of the British breeding range used different non-breeding areas from one another, whereas Twite from different parts of the continental breeding range used similar non-breeding areas. There was essentially no overlap during the non-breeding season between British and continental Twite.     

Core concepts of spatial prioritisation in systematic conservation planning

Systematic conservation planning (SCP) is a field of conservation biology concerned with delivering on‐the‐ground actions that achieve conservation goals. It describes a set of operational models that cover both design and implementation of conservation, with a strong focus on mobilising the collective action typically required to implement conservation. SCP, as it was originally described, was composed of six different stages: collection of data, identification of conservation goals, evaluation of the existing protected area network, design of expansions, implementation of conservation action, and long‐term maintenance of biodiversity in the network. Since then, the operational model has been expanded into several different variants. Conservation actions applied inside SCP include establishment and expansion of reserve networks and allocation of habitat restoration and management. Within the broader context of SCP, there is a fundamental biogeographic‐economic analysis frequently called spatial conservation prioritisation or conservation assessment, which is used for identifying where important areas for biodiversity are and how conservation goals might be achieved efficiently. Here, we review the usage and meaning of the 12 biogeographic‐economic core concepts of SCP: adequacy, complementarity, comprehensiveness, effectiveness, efficiency, flexibility, irreplaceability, replacement cost, representation, representativeness, threat, and vulnerability. Some of the concepts have clear definitions whereas others may have alternative and possibly conflicting definitions. With a comprehensive literature review literature, we elucidate the historical backgrounds of these concepts, the first definitions and usages, alternative later definitions, key applications, and prior reviews. This review reduces linguistic uncertainty in the application of SCP. Since SCP is a global activity with a multitude of different stakeholders involved, it is vital that those involved can speak the same language. Through these concepts, this review serves as a source of information about the historical development of SCP. It provides a comprehensive review for anyone wishing to understand the key concepts of spatial prioritisation within SCP.     

中国大陆沿海水鸟栖息地保护优先区及空缺分析

中国大陆沿海湿地是东亚-澳大利西亚候鸟迁徙的重要停歇地,自然湿地丧失与退化已经严重威胁到水鸟生物多样性的稳定性,急需开展物种及其栖息地的保护工作。识别中国大陆沿海水鸟保护优先区,针对保护优先区进行保护优先等级划分,确定目前尚存的保护空缺,是针对性开展水鸟栖息地保护的前提。以中国大陆沿海11省、自治区、直辖市沿岸湿地为研究区,整合鸟类网站、水鸟调查报告和文献中的水鸟调查数据,采用热点分析方法,确定水鸟保护优先区,将每个地块上满足水鸟保护优先区识别标准的物种数量占所有地块中满足标准的物种数量最大值的比例划分成0.5 ≤ P_i ≤ 1、0.25 ≤ P_i < 0.5、0 < P_i < 0.25三个区间,确定对应的I类、II类和III类水鸟保护优先区保护优先等级;结合国家自然保护地名录,确定水鸟保护优先区保护空缺。结果显示：共有65块中国大陆沿海水鸟保护优先区,记录到满足热点分析标准的水鸟物种共76种,其中受胁物种18种。水鸟保护优先区保护优先等级属于I、II、III类的分别有8块、10块、47块,且水鸟保护优先区保护优先等级属于I、II类的地块集中分布在上海以北的区域,水鸟保护优先区保护优先等级属于III类的地块主要分布在上海以南的区域。38块水鸟保护优先区存在保护空缺,占总数的58.46%,这些保护空缺地中保护优先等级属于I类和II类的地块共6块,建议针对这些地块单独建立保护机构或纳入现有周边的保护体系中。     

Introducing Indonesian Medical Students to Rainforest Conservation and Community Health in the Field: A Practicum Experience in East Kalimantan

This article describes a practicum experience developed between a conservation organization (The Nature Conservancy) and a medical school (The Faculty of Medicine at Mulawarman University in East Kalimantan). Through this practicum, groups of medical students from Mulawarman have assisted with baseline and follow-up community evaluations in remote villages along the Kelay River, Berau District. These evaluations were done in conjunction with the Kelay Conservation Health Program, a program designed to improve health and healthcare for local people, mostly former hunter–gatherers, in an area of rainforest that the conservation organization seeks to protect. Besides gaining experience in community health assessment, through this practicum medical students also gained field experience and knowledge in rural and remote area health and healthcare in Indonesia and had an opportunity to explore linkages between conservation and health. At the conclusion of their time with the program, participating students also presented individual problem-based reports on relevant topics to students and faculty at the Medical School and to the District Health Department. This partnership between a conservation agency and a medical school in a developing country is unusual, but has been very well received by all stakeholders involved. Because of this, Mulawarman is now planning to make Kelay into a formal training site for its students. This experience may serve as a model for other groups interested in promoting ecosystem health education to future health professionals in the developing world.

Conservation needs of amphibians in China: A review

The conservation status of all the amphibians in China is analyzed, and the country is shown to be a global priority for conservation in comparison to many other countries of the world. Three Chinese regions are particularly rich in amphibian diversity: Hengduan, Nanling, and Wuyi mountains. Salamanders are more threatened than frogs and toads. Several smaller families show a high propensity to become seriously threatened: Bombinatoridae, Cryptobranchidae, Hynobiidae and Salamandridae. Like other parts of the world, stream-breeding, high-elevation forest amphibians have a much higher likelihood of being seriously threatened. Habitat loss, pollution, and over-harvesting are the most serious threats to Chinese amphibians. Over-harvesting is a less pervasive threat than habitat loss, but it is more likely to drive a species into rapid decline. Five conservation challenges are mentioned with recommendations for the highest priority research and conservation actions.
