Is helping a beneficial learning experience for red-cockaded woodpecker (Picoides borealis) helpers?

Several hypotheses have been suggested to explain the evolution and maintenance of helping behavior in cooperatively breeding birds, one of which we investigated in the red-cockaded woodpecker (Picoides borealis). Helping may provide a learning experience that improves reproductive success once the helper becomes a breeder. We used data collected from a population of red-cockaded woodpeckers in the Sandhills of North Carolina to compare the reproductive success of 2-year-old breeders that were helpers at age 1 (helping experience) to those that were floaters or solitary males at age 1 (no helping experience). Reproductive success of the two groups was similar, indicating that helping provides no experience useful in reproduction. We reject the learning experience hypothesis as an explanation for the maintenance of helping behavior in red-cockaded woodpeckers.

The relative role of age and experience in determining variation in body mass during the early breeding career of the Common Tern (<Emphasis Type="Italic">Sterna hirundo</Emphasis>)

Body mass is a consistent individual trait that characterises the state of adult birds and mammals and is positively related with long-term reproductive success. However, whether and to what extent body mass changes over lifetime in long-lived birds is poorly studied. In this paper, we investigate how individual body mass varies with age. Furthermore, we try to separate possible effects of age and experience on body mass. This study was conducted in a Common Tern colony on the German Wadden Sea coast. Transponders allowed registration of individuals throughout the breeding season and consecutive years with an antenna system combined with electronic balances for recording individual body-mass changes within and between years. Individual body masses of males and females were measured during three stages of the breeding season: at arrival, during incubation and chick rearing when mass was lowest in both sexes. Individual-based longitudinal analyses clearly showed that body mass during arrival, incubation and chick rearing increased up to an age of 5 or 6 years. First-time breeders had lower body mass than experienced breeders. Experience had stronger effects on incubation mass than age. Recruiting age also affected body-mass development of breeders: Three-year-old recruits showed a stronger increase in mass with experience than 4-year-old recruits. We assume that increasing experience enables birds to cope better with the physiological challenge of reproduction. To explain the general phenomenon of higher body mass in older birds, our results support the constraint hypothesis rather than either the selection or restraint hypothesis.     

旅游体验对旅游者环境态度和环境行为影响的纵向追踪研究

目前国内关于旅游体验对环境态度和行为影响的纵向追踪研究较为缺乏。论文以自然旅游地黄山为案例地,通过纵向调查,采用配对样本t检验比较同一批次旅游者游前、游后以及3个月后的环境态度和环境行为。研究发现：1）旅游体验对旅游者环境态度基本没有影响。2）旅游体验对旅游者环境行为存在显著影响。短期影响表现为：特定地点环境责任行为中的教育、身体和法律行动显著改善,一般环境责任行为中教育、消费、说服、身体和法律行动显著改善;长期影响表现为：特定地点环境责任行为中的教育、消费、身体行动和一般环境责任行为中的消费、身体、法律行动显著改善。环境行为的改变主要是通过旅游体验中的认知和情感刺激引起的,包括预期愧疚、集体自豪感、环境知识、负面后果认知、自我效能、环境解说等因素。文章最后讨论了管理意义和研究不足。

国外实施低碳经济转型对中国低碳经济发展的启示研究

中国人口基数大、发展水平低、人均资源占有量少的特点以及巨大燃煤量也导致中国环境污染问题愈发严重,决定了中国必须向发展低碳经济转变.中国应通过提高能源使用率,减少资源消耗,开发可再生能源等途径,削弱资源对经济发展的限制.虽然中国的基本国情和发展现状使中国向低碳经济发展转变的难度较大,但是发达国家实施低碳经济转型的实践活动为中国发展低碳经济提供了许多宝贵的经验,让中国发展低碳经济的过程中少走许多弯路,使中国向低碳经济更好的发展.     

美日臭氧污染问题及治理经验借鉴研究

以臭氧(O_3)为主要成分的"光化学氧化剂"是光化学烟雾的真身。臭氧污染受臭氧前体物排放及其复杂的相互转化关系控制,导致臭氧污染问题在治理过程中具有高度的复杂性和反复性,甚至成为全球性环境难题。我国城市群臭氧污染问题继PM2.5污染后日趋突出,本文探讨和总结了美国洛杉矶、日本东京等大都市在污染治理方面的经验,以期为我国构建更加全面、科学、系统的治理体系推进臭氧污染防治工作提供借鉴。     

International experience of green development in Western China: an overall review of policy and practice

Green development emphasizes co-development between economic and environmental dimensions, and is a people-centered sustainable development approach. Western China demands green development, and international experience could provide necessary, unique and important help and support for Western China to achieve its green development goals. This paper has made a comprehensive overall review and analysis of international experience in green development policy and its implementation, in particular, OECD countries’ (mostly Australia and Canada) experience have been analyzed following the major policy foci defined by the Task Force on Strategy and Policies on Environment and Development in Western China initiated by China Council for International Cooperation on Environment and Development (CCICED). Data and information were gathered from the field surveys and investigations, expert meetings, as well as literature review. The main sessions include policy framework and road map establishment, implementation and performance assessment, co-development between economic development and environmental protection, as well as green employment and poverty alleviation. The paper has addressed five policy considerations for the future promotion of green development in Western China.
