A non-profit approach to addressing the effects of urbanization in the Lake Pontchartrain Basin, Louisiana

The Lake Pontchartrain Basin in southeast Louisiana is an estuarine watershed encompassing New Orleans, Baton Rouge, and wetlands that are an integral part of Louisiana's unique culture. In recent decades rapid growth and poorly planned development have resulted in a decrease in water quality and habitat loss, especially in St. Tammany Parish on the north shore of Lake Pontchartrain. In 1989, the Lake Pontchartrain Basin Foundation (LPBF), an environmental, non-profit organization, was formed to address and rectify environmental issues in the Basin. LPBF accomplishes its mission through programs addressing water quality, habitat protection, geographic information science, public access, and education.LPBF used the recent, rapid development occurring in St. Tammany Parish as a case study to examine the relationship between land use, water quality, and development in the Basin by investigating habitat change/urbanization, development in flood plains, and water quality. Through the integration of LPBF programs, it was found that urbanization is having a devastating impact on the parish's natural habitats and severely degrading water quality. Using these results, LPBF is educating Basin citizens on the protection of their habitats and water quality to insure that these resources may be available for future generations.     

从人域契约到自然契约：生态损害赔偿法理要义之证成与功能拓展

生态损害赔偿作为我国环境保护领域最重要的救济性制度之一,其规范的目的、动机、价值、架构等诸构件决定着生境主体及其权利何以成立的基础性承载和充足性解释。生态损害赔偿制度从人域契约的“人域法”层面确立了“生境”的独特价值、独立的存在权和独立的法律人格;从自然契约的“人际法”层面打破了“人域法”理论的封闭体系,将伦理价值植入环境法律规则之中,摆脱了传统“人域法”对非政治化和非伦理化的唯理主义形式的追求和表达,复兴了中华法系“法律应当伦理化而非工具化”的灵魂与传统,确立了法益保护从“人域优先”向“人际优先”法律价值的转换,丰富了环境法理学的秩序观念和学理原则,拓展了传统人域法“主体中心主义”规则体系的界限与边界,为开启我国环境法从“主体模式保护”向“关系模式保护”生态法律观的变革与价值功能的转换提供了超越性的实践尝试与理论探索。     

胶东半岛与辽东半岛现代植被发展趋势研究

通过胶东半岛、辽东半岛及庙岛群岛５２个样地乔木更新层情况的调查,采用主成分分析方法进行样地资料分析,指出现代植被发展趋势的两个阶段：松类—栎类混交林阶段与栎类—松类混交林阶段;生境变化趋势由庙岛群岛的温湿向辽东半岛略暖温和胶东半岛的暖干过渡．     

论民族生境与民族文化建构

民族学经过一个多世纪的探索，逐步地达成了一个共识，建构一种文化并不是一件轻而易举的事情。文化是指导人类生存发展延续的信息系统，文化的建构是以所处自然生态系统为底本，以并存的社会生态系统为参照，文化这一信息系统不断偏离与回归所处自然生态系统与社会生态系统，在世代延续过程中逐步认知、积累其成败的经验与教训，并在传承的过程中不断地完善和丰富起来。民族以文化为分野，不同民族所处自然环境与社会环境互有差异，这就形成了民族生境的差异性，而民族生境的差异性也同样会建构出不同民族文化事实体系的差异性来。     

当代灾疫防治的目标任务

当代灾疫防治必须以频频爆发、首尾相连的灾疫状态为逻辑起点,以反思批判面对灾疫的自然主义立场和扬弃灾疫防治的被动应急模式为前提,确立为＂消解灾疫而学习、为恢复生境而节制、为生态安全而行动＂的实践理性姿态,构建＂在全球框架下重建生境、在国际平台上重建生态家园、在全球视域中创建生态文明＂的三级目标体系,以重建生境主义价值导向体系、共在互存的整体存在方式和共生互生的动态生存方法为基本任务。     

论生态美学在城市人居环境建设方面的应用

将生态美学引入城市人居环境建设是一个全新的课题。从生态美学的基本概念入手,阐述生态美学在城市人居环境建设方面的应用方法,确定生态美学于城市人居环境建设中的应用原则,并探讨其动态和静态应用方法,是这一研究领域的基础性研究工作。     

Possible influences of habitat characteristics on the evolution of semelparity and cannibalism in the hump earwigAnechura harmandi

The possible influences of life history and habitat characteristics on the evolution of semelparity and cannibalism in the hump earwigAnechura harmandi were studied. This species is univoltine and overwinters as an adult. Females laid single egg-batches during winter in nests under stones at a riverside in a valley. They took care of the eggs which hatched in early spring and the offspring ate their mother before dispersing. The valley was sometimes flooded in summer. Nymphs emerged as adults and dispersed to elsewhere before the rainy season arrived. They returned to the riverside after the rainy season. The flooding and/or summer heat seemed to be the selective force for the evolution of dispersal behavior and semelparity in this species. The cannibalism of the female parent by her offspring seemed to have readily evolved after the evolution of semelparity. The unfavorable environmental conditions seemed to have a large effect on the evolution of semelparity and cannibalism in this species.

灾疫政治伦理学的一般思考

在当代社会,频频爆发的灾疫成为其世界性难题,求解这一世界性难题的根本之道,需要灾疫政治伦理学的导向。灾疫政治伦理学的根本任务,就是导向当代灾疫防治必须以创建低碳社会、提高环境软实力、建设生境文明为实质目标。为此,灾疫政治伦理学必须引导当代灾疫伦理防治遵循全球生境原则、共生互生原则、普遍利益原则,构建生境主义价值体系,探索可持续生存式发展道路,重建以限度生产和简朴生活为基本诉求的生境主义存在方式。     

Habitat stability and the larval mosquito community in treeholes and other containers on a temperate Island

The temporal fluctuation of water levels and the presence of mosquito larvae were investigated for four types of small container habitats (treeholes, bamboo stumps, cemetery stone vases, and cemetery stone vessels) on Kabeshima Island in Kyushu, southwestern Japan. The probability that containers held water was positively correlated with the quantity of the preceding rainfall and with the depth and volume of the containers. It was estimated that dehydration occurred more regularly in autumn and winter than in summer. The probability that mosquito larvae were present in each type of container was positively correlated with habitat stability in terms of the probability of the existence of standing water and the coefficient of variation of the water level. Twelve species of mosquito larvae, including two rare predators, were found. Species composition differed between the different types of container. Although 4 to 10 species used each type of container, the median number of species per container was two for treeholes and bamboo stumps, and one for the others. The dominant species wasTripteroides bambusa in treeholes and bamboo stumps,Aedes albopictus in stone vases, andA. japonicus in stone vessels. The larval mosquito community, which lacked major predators, possessed the following features that may facilitate the coexistence of many species: (1) niche segregation amongst species in terms of their selection of container types; (2) an aggregated distribution of the individual species among containers of the same type; (3) high intraspecific mean crowding (and hence probably intense intraspecific competition) in the dominant species in each type of container; (4) independent species associations within the same type of container; and (5) low interspecific mean crowding (and hence probablynot intense interspecific competition) between species in the same type of container.
