Large‐scale patterns of fish diversity and assemblage structure in the longest tropical river in Asia

Although the Mekong River is one of the world's 35 biodiversity hot spots, the large‐scale patterns of fish diversity and assemblage structure remain poorly addressed. This study aimed to investigate the fish distribution patterns in the Lower Mekong River (LMR) and to identify their environmental determinants. Daily fish catch data (i.e. from December 2000 to November 2001) at 38 sites distributed along the LMR were related to 15 physicochemical and 19 climatic variables. As a result, four different clusters were defined according to the similarity in assemblage composition and 80 indicator species were identified. While fish species richness was highest in the Mekong delta and lowest in the upper part of the LMR, the diversity index was highest in the middle part of the LMR and lowest in the delta. We found that fish assemblages changed along the environmental gradients and that the main drivers affecting the fish assemblage structure were the seasonal variation of temperature, precipitation, dissolved oxygen, pH and total phosphorus. Specifically, upstream assemblages were characterised by cyprinids and Pangasius catfish, well suited to low temperature, high dissolved oxygen and high pH. Fish assemblages in the delta were dominated by perch‐like fish and clupeids, more tolerant to high temperatures, and high levels of nutrients (nitrates and total phosphorus) and salinity. Overall, the patterns were consistent between seasons. Our study contributes to establishing the first holistic fish community study in the LMR.

Soil protection for a sustainable future: options for a soil monitoring network for Ireland

The increased recognition of the importance of soil is reflected in the UN Post‐2015 Development Agenda with sustainable development goals that directly and indirectly relate to soil quality and protection. Despite a lack of legally binding legislation for soil protection, the European Commission remains committed to the objective of soil protection. However, the achievement of a legally binding framework for soil protection relies on the implementation of a soil monitoring network (SMN) that can detect changes to soil quality over time. As beneficiaries do not pay for the provision of soil information, the options for soil monitoring are limited. The use of existing data sets should be considered first. Using Ireland as an example, this research explored the opportunities for a SMN for Ireland considering three existing national data sets. The options for a SMN are considered in terms of their spatial and stratified distribution, the parameters to be measured and an economic analysis of the options proposed. This research finds that for Ireland, either a 10 or a 16 km² grid interval stratified by land use and drainage class offers the best potential in relation to the spatial distribution of existing data sets to reflect local data at a national level. With existing data, the stratified SIS data using the 16 km² grid offers the best value for money, with baseline costs for analysis, excluding field costs, of between €706 481 and €2.8 million. Acknowledging the impossibility of measuring all parameters with ideal frequency, this study proposes a two‐tier system for optimized monitoring frequency. Parameters must anticipate future policy requirements. Finally, the implementation of a SMN must be accompanied by standardized methods, defined thresholds and action mandates to maintain soil quality within allowable limits.     

自然保护地环境教育实践与研究现状

环境教育是多学科融合的激发人们环境保护意识、培养正确环境价值观的教育。国际上自然保护地环境教育研究主要集中在环境教育内容和形式、环境教育效果评价及其影响因素分析、环境教育监测和法律体系完善等领域。在实践方面，环境教育内容和形式不断丰富，出现相对多样化的环境教育模式和较为健全的环境教育评价与法治管理体系。典型的有美国黄石公园设置的少年巡逻员岗位项目、英国的野外环境教育培训基地和日本的生态自然体验露营地等。我国自然保护地环境教育研究关注了国外相关理论与实践，侧重于从宏观层面对我国环境教育提出原则性、策略性的建议等。文中在分析国际自然保护地环境教育研究与实践的基础上，结合我国自然保护地环境教育现状及存在的问题，提出了完善环境教育内容和形式、建立健全环境教育评价和法律体系等发展建议。     

社会林业与五指山的自然保护

五指山自然保护区是世界上现存地势最高的原始热带雨林之一，是我省目前面积最大的自然保护区，也是海南三大河流的发源地。但由于保护区横跨琼中、通什、保亭三县、市，紧邻保护区还生存着众多贫困的黎、苗族村民。因此，保护区与周边社区的联系是十分紧密的，社区的发展也直接影响到五指山热带天然林的保护。海南省林业局中德海南热带林保护和恢复项目在社会林业与五指山森林的保护上做出了有益的尝试，就在全省来说，也是首次对社会林业与森林保护上进行的探索。五指山地区社会林业的研究，对保护海南热带雨林也有着积极的意义。特对社会林业与五指山的森林保护进行了阐述、分析和设想。     

The Brief Introduction to the Sino-US Joint Centers for Soil and Water Conservation and Environmental Protection

Erosion and transport of soil has worldwide implications for agriculture, landscape stability, climate, natural hazards, and clean, renewable resources of water and air. Assured access to clean water and a healthy and safe environment requires an ethic of conservation and protection. The minimum scale in which these principles apply successfully is basin wide. These are the fundamental concerns of the Sino-US Centers for Soil and Water Conservation and Environmental Protection.
