镉超积累植物龙葵叶片中镉的积累与有机酸含量的关系

采用盆栽试验方法,研究镉超积累植物龙葵(Solanum nigrum L.)不同生育期叶片中有机酸的含量与组成,及其与镉生物积累的关系.结果表明,当土壤中镉浓度为25μg.g-1时,苗期和成熟期龙葵叶片镉积累量均达到100μg.g-1以上,且地上部镉含量大于根部镉含量.苗期与成熟期有机酸的含量变化差异显著,苗期龙葵叶片4种有机酸的含量大小为乙酸>酒石酸>苹果酸>柠檬酸;成熟期有机酸含量顺序为苹果酸>酒石酸、乙酸>柠檬酸.苗期龙葵叶片中酒石酸含量与镉含量呈极显著相关,成熟期则发现乙酸和柠檬酸含量与叶片中镉含量呈显著相关,说明龙葵叶片中酒石酸、柠檬酸和乙酸分别可以指示不同生育期龙葵叶片中镉的积累.     

Competition gives way to cooperation: rethinking Sino-Indian relations in climate change negotiations

In global climate change politics, China and India have worked closely with each other, representing two big emitters from the developing world. This article reviews Sino-Indian cooperation during four UN climate change negotiations from 2009 to 2012. Their collaboration echoed the perception of neorealism in international relations (IR) studies that states will seek “external balancing” for maximizing national “relative gains”. China and India are expected to continue their cooperation on climate change issues when sharing the same structural position as big economies and big emitters, the same pressure in carbon emission reductions, and the same goal of improving living standards for their citizens. Encountering the devastating impacts of climate change and the deadlock in responsibility division in current global climate change governance, this work seeks to shed light on the evolving multilateral governance environment and its complex implications for Sino-Indian relations from an IR perspective.     

Host species affects the growth rate of cuckoo (Cuculus canorus) chicks

The cuckoo (Cuculus canorus) is an obligate interspecific brood parasite. When about to lay an egg, the female must decide which nest to parasitise. A high-quality host species should be preferred, to enhance the possibility of producing a viable offspring. In this study, we investigated the effects of two closely related host species, the great reed warbler (Acrocephalus arundinaceus) and the reed warbler (A. scirpaceus) on the growth rate of cuckoo nestlings. We found that cuckoo nestlings raised by the larger host species, the great reed warbler, grew significantly faster and became statistically significantly larger at fledging than nestlings raised by the smaller host, the reed warbler. Our results indicate a qualitative difference between the two host species. The great reed warbler, considered to be the best host, was parasitised at a higher rate than the reed warbler.

Development of Future Generations： Oriented Virtual Negotiation Support System for Intergenerational Conflict

Intergenerational conflict coordination is the fundamental requirement and core of sustainable development. In this paper, through the analysis of the future generations-oriented management mechanisms for intergenerational conflict, the idea of mechanisms and institution building for the coordination and management of intergenerational conflict is put forward. Furthermore, the future generations-oriented virtual negotiation support system （NSS） for intergenerational conflict is developed, built on the analysis of the process simulation of intergenerational wealth transfer, intergenerational equilibrium allocation of resources, and strategies for the mitigation and avoidance of intergenerational conflict, through the application of advanced IT technology. The virtual NSS for intergenerational conflict is helpful to the practical application of the sustainable development theory; on the other hand, it can be applied directly to the intergenerational equilibrium allocation of resources, national economic accounting, formulation of sustainable development strategies and other urgent national economic and social development issues. Finally, the sustainable development theory can be enriched and extended. Therefore, the development of the future generations-oriented virtual NSS for intergenerational conflict has certain theoretical and practical effects on the theory of sustainable development.     

应对二氧化碳浓度上升问题的研究:CO_2的捕获、储存与利用

为了缓解日益严重的CO2浓度升高导致的温室效应等环境问题,针对各国CO2过量排放与温室效应逐渐加剧的现状,讨论传统CO2减排方法与CO2的捕获、储存与利用(CCSU)的优缺点和优势互补,论述针对大型CO2排放点的减排措施——CCSU的必要性。对CCSU进行系统的介绍和认识,并对CCSU所包含的各种捕获技术、储存技术以及利用技术的特点进行对比和分析,论述其适用范围、地域和经济因素。结合国外一些现有的应用CO2的先进技术和经验,对CO2的捕获与利用的联用作出分析和展望。尤其是CO2的化工利用具有广阔的研发和发展前景,CO2EOR(CO2提高采收率技术)在技术和经济上具有实际应用意义。为新型环保型能源体系的建设提供参考。     

Waiting for Peace: Perspectives from Action-oriented Research on the Humanitarian Impasse in the Caucasus

Cease-fires in the Caucasus during the past five years have prevented large-scale life-threatening emergencies and created space for peace negotiations. Yet genuine conflict resolution and normalisation have proven elusive, frustrating the return of uprooted populations and constraining reconstruction. This paper reviews a series of seven strategy sessions held in Moscow and the Caucasus in late 1998 to reflect upon the performance of humanitarian agencies and stimulate greater synergies with diplomatic actors. An experiment in promoting discussion of recently conducted independent policy research throughout the north and south Caucasus, the series resulted in a fresh look at the issues in the region and at agency headquarters. The generic nature of the policy challenges gives the experience potential relevance well beyond the region.     

Strategies to overcome barriers to the development of sustainable agriculture in Canada: The role of agribusiness

Strategies to involve agribusiness in the development of sustainable agricultural systems have been limited by the lack of a comprehensive conceptual framework for identifying the most critical supportive policies, programs and regulations. In this paper, we propose an efficiency/substitution/redesign framework to categorize strategies for modifying agribusiness practices. This framework is then used to identify a diverse range of short, medium, and long-term strategies to be pursued by governments, community groups, academics and agribusiness to support the transition. Strategies discussed include corporate greening, ethical investment, changing the legal status of the corporaton, new business forms and the development of ecological economics.     

Environmental problem-solving and land-use management: A proposed structure for Australia

A three-tiered structure of land-use and environmental management is here proposed for Australia. The structure is based on the idea that environment means the environment of people, and that environmental problems arise when a change in the interaction between people and their environment leads to conflicts about the use of land and resources. The heterogeneity of society means that a range of human aspirations and value systems must be satisfied by environmental managers. Existing methods of environmental management fail to achieve these objectives, due to inadequate perception of environmental problems by decision-makers, and the inability of currently available impact assessment techniques to resolve human conflicts associated with the use of land and resources. The main work of planning and managing land use and the environment would be carried out by regional authorities, supported by federal and state policy. Examples are given of moves towards regional administration in England and Wales, Western Australia, Australia and New Zealand. Community participation in the decision-making process is essential and can be achieved by electoral representation to the authoritative bodies and through procedures that ensure informed public comment on planning proposals.
