Industrial Ecology Education at Wuhan University

China requires industrial ecology (IE) skills and knowledge to deal with the contradiction between rapid economic growth and subsequent environmental pollution and resource depletion. Industrial ecology education was introduced in China in 1997 and now a few Chinese universities offer IE courses. Wuhan University is one of them and since 1999 has committed itself to promoting IE education. The university offers different curricula for different majors at all levels: undergraduate, master's, and doctoral. Between 1999 and 2004 more than 5,000 students received IE education at Wuhan University. Although inadequate human resources and a lack of relevant textbooks present challenges to further developing IE education in China, as more universities pay attention to IE, more courses will be developed. It is believed that IE education in China will blossom in the near future.

Freshwater ecology: changes, requirements, and future demands

The past development and evolution of limnology as a discipline has demonstrated that experimentally controlled disturbances of parts of aquatic ecosystems are essential for quantitative evaluation of causal mechanisms governing their operation. Correlative analyses and modeling only establish hypotheses, not causality, and allow only therapeutic management applications. Rather than constantly searching for differences, commonality must be sought. Among the large diversity of species, communities, and biogeochemical processes controlling growth and reproduction, commonality emerges at the levels of regulation of metabolism. Five areas of current and future limnological research are discussed in relation to greatest needs and promise to yield insights into material and energy flows in freshwater ecosystems and their effective management: (1) coupled metabolic mutualism in the physiological ecology of microbes (viruses, bacteria, fungi, and protists) and their biogeochemical, especially organic, couplings with the environment; (2) biochemical regulation of collective metabolism, recycling, and bioavailability of nutrients and growth regulators; (3) application of genetic and molecular techniques to addressing biogeochemical, evolutionary, and pollution remediation problems; (4) recognition that the metabolism within lakes and streams is dependent upon and regulated to a major extent by organic matter of the drainage basin and especially by the land-water interface biogeochemistry; and (5) recognition that food-web alterations ("biomanipulation") are short-term, expensive therapeutic tools that may minimize effects of eutrophication but will not solve or control eutrophication.

REPRODUCTION AND LARVAL DEVELOPMENT OF LABEO UMBRATUS (PISCES,CYPRINIDAE) IN THE TYUME RIVER,EASTERN CAPE

SUMMARY

AN account is given of some aspects of the reproductive ecology and larval development of Lubeo umbrutus which is of great importance in the Eastern Cape due to its abundance in rivers and dams.

The sex ratio was found to be approximately 1:1 and females probably have a longer life span than males. Spawning takes place from October to January. Males become sexually mature at a length of 14 cm and females at a length of 20 cm. A spawning site is described. There is a curvilinear relationship between length and fecundity with the average fecundity increasing from 11 000 in fishes with a length of 20 cm to 48 000 in fishes with a length of 32 cm. Larval development from hatching to an age of 12 days is described.     

Australia's place in the global restoration challenge: Interview with Richard Hobbs

Summary   This interview with Professor Richard Hobbs, a prominent Australian researcher, professor and journal editor, traces his involvement in ecology and the relatively new disciplines of landscape ecology and restoration ecology. Born and educated as a plant ecologist in Scotland, Richard undertook postdoctoral research in the USA before taking up a series of research positions in Australia that steered him towards landscape ecology and restoration ecology. Having maintained an interest and involvement in international organizations, Richard provides comment in this interview on the progress of ecological restoration practice in Australasia compared to North America and comments on the need for ensuring research in these disciplines is strongly linked to management, is as broadly relevant as possible, and, is carried out at appropriate scales.     

Diurnal activity patterns and feeding ecology of the endemic geladas (Theropithecus gelada) in the Simien Mountains National Park,Ethiopia

Diurnal activity patterns and feeding ecology of geladas (Theropithecus gelada) in Chenek, Simien Mountains National Park, were studied from January 2010 to April 2010. Data were gathered for 7 days per month starting from early in the morning to dusk. The study site (1805 ha) was divided into five blocks and a total of 397 individuals were counted using simultaneous census method. One band with 21 individuals was selected as a study group and scan sampling was used to study their diurnal activity patterns and feeding ecology. Geladas dedicated significantly more time to foraging than to other diurnal activities. They spent the majority of feeding time foraging on grass, and allocated little time to feeding on leaves, shoots, and flowers. Geladas of all age classes devoted the least time to resting, and spent similar amount of time moving. The study band was observed to interact with people, and to steal food from tourists and local people. Raising local people's awareness of geladas ecology and behavior might be a necessary component in the species' successful management and conservation.     

流域生态学的发展困境——来自河流景观的启示

随着中国生态环境问题越来越多地呈现出流域特性,流域生态研究的重要性和紧迫性也日渐凸显。整合流域生态研究,形成一个有效的研究体系,流域生态学迄今未能予以实现。通过对"流域生态学"和"河流景观"这两个相近概念提出过程的比较研究,探讨流域生态学发展困境产生的原因,为流域生态研究体系的构建提供思路。分析结果显示流域生态学目前主要存在两个不足:1)因为提出流域生态学概念的关键现实需求不明确,导致难以确定其核心科学问题;2)因为没有相应的流域生态系统概念模型,进而也就难以带动相关研究落实跟进。要推进流域生态学的发展,第一步要做的就是明确流域生态研究体系构建的核心现实需求,并对流域生态系统进行一个概念模型上的相应设计。     

A Model for Defining West Nile Virus Risk Perception Based on Ecology and Proximity

West Nile virus (WNV) has made considerable impact as an emerging infectious disease, spreading from coast to coast across North America since 1999. The disease has exhibited great spatial variability in North America, making an ecosystems approach to understanding the local human and vector ecology critical to prevention and control. This study underscores the importance of employing both personal prevention and community participatory approaches to create messages that have been adapted to the local ecology and are designed to reduce the risk of human infection with this mosquito-borne virus. As the virus spreads into new areas, underlying attitudes toward mosquitoes and the local perception of environment/ecology can affect the success of control and prevention measures. This work presents results from focus group discussions conducted in two Colorado counties in 2003, a year of significant WNV activity in the state. Issues addressed include residents’ assessment of risk and how this perception varied by age group and location, use or nonuse of repellents, and community attitudes toward mosquito control in areas with different ecologies and histories of mosquito-borne disease. The need to address individual components of personal prevention, to target prevention to specific audiences, and to disseminate prevention messages through local channels is discussed. The authors propose including aspects of ecology and disease proximity in understanding risk perception and addressing emerging diseases with a prominent ecological component.     

盐度对红树植物海莲幼苗的生长和某些生理生态特性的影响

本文主要探讨了不同盐度海水砂培的海莲幼苗生长量和某些生理生态特性与盐度的相关效应。结果表明,生长基盐度20‰以上,海莲繁殖体的萌苗时间推迟,成活率降低;随着盐度的提高,幼苗高生长量降低,叶片变小;叶片叶绿素含量随盐度提高而提高,相反的叶片可溶性糖含量则降低,而叶片可溶性蛋白质含量变化不明显;叶片组织内氯含量随盐度提高而提高;随着盐度的提高,叶片蒸腾作用减弱,气孔导度降低。由此表明,海莲幼苗适宜生长的盐度范围在15‰以下,更高的盐度表现为生态抗盐适应性生长。     

Child social ethology and peer relations: a developmental review of methodology and findings

During the last three decades, developmental research has increasingly emphasized the relevance of peer relations in children’s socialization. However, most studies of child development still focus upon individual differences in social status, tacitly neglecting relational constraints inherent in the ecology of the peer group. In contrast, socioethological approaches have stressed that natural groups provide a variety of distinct social roles that may have a differential impact upon individual growth and development. However, ethological analyses have often been limited to aggressive relations and group dominance structures. Comparable studies of affiliative organization have been hampered by the paucity of models for the study of cohesive social structure, only recently having begun to overcome this obstacle. A potential third dimension of preschool peer group ethology, object use, has been relatively neglected in studies of peer relations. However, recent research suggests that object use is a salient and important component of the social world of the young child. This article reviews methodology and recent findings in the area of peer relations and discusses the developmental implications of this work.

Parent-offspring conflict and the cultural ecology of breast-feeding

Lactation constitutes a major focus for research in international health because of its dramatic impact on child survival; evolutionary biology has investigated lactation as an important aspect of parenting strategy, with implications for understanding parent-offspring conflict. These perspectives are brought together in an attempt to develop integrated models for an issue of key international health concern: the duration of exclusive breast-feeding and the timing of weaning. This analysis highlights the relevance of evolutionary theory for practical problems in public health, and it suggests the utility of public health outcomes for addressing evolutionary questions. Thomas McDade received his Ph.D. degree in anthropology from Emory University in 1999 and is currently an assistant professor in the anthropology department at Northwestern University. His research interests include biocultural perspectives on issues related to health and human development, with current attention focused on the cultural and evolutionary ecology of human immune function.
