Community Ecology of Tropical Birds, the tropical ecosystems is one of the most biological diverse habitats on the earth. Seventy six per cent of all centers of avian endemism occur in tropical regions and the same is true for many plant and animal communities. Birds are important component of biological diversity and their ecological, cultural, recreational and economic benefits are recognized universally. They act as vital links in many food webs and often serve as highly visible biological indicators of ecosystem health. Many bird populations are declining all over the world due to habitat loss and fragmentation, predation, pesticide use, invasive exotic species and other factors. This book is about the ecology of tropical bird community, all together 12 chapters are described and divided into two parts. The first part of this book looks at the forest bird community including status and distribution, species-abundance relationship, seasonal changes, vertical distribution and habitat utilisation. The second part provides detailed ecology of wetland bird community. This book will be an invaluable resource for field scientist, researchers, students, and naturalists in the field of Ornithology.

Two new volumes of Methods in Enzymology continue the legacy of this premier serial with quality chapters authored by leaders in the field. Circadian Rhythms and Biological Clocks Part A and Part B is an exceptional resource for anybody interested in the general area of circadian rhythms. As key elements of timekeeping are conserved in organisms across the phylogenetic tree, and our understanding of circadian biology has benefited tremendously from work done in many species, the volume provides a wide range of assays for different biological systems. Protocols are provided to assess clock function, entrainment of the clock to stimuli such as light and food, and output rhythms of behavior and physiology. This volume also delves into the impact of circadian disruption on human health. Contributions are from leaders in the field who have made major discoveries using the methods presented here.

While sea cucumber is one of China's and Asia's most prized seafoods, and aquaculture programs are being developed on a huge commercial scale, Chinese expertise and knowledge in this area has not been well disseminated worldwide. The Sea Cucumber Apostichopus japonicus is the first book to bridge this gap by compiling key information related to hatchery and aquaculture techniques, nutritional and medical values, markets, and trade flow of the number one sea cucumber species. It summarizes the historical and most recent developments in the trade and aquaculture of Apostichopus japonicus, as well as important aspects of its anatomy, population dynamics, reproduction, development, physiology, and biochemistry. With sea cucumber harvest and aquaculture booming worldwide, comprehensive knowledge of China's technological breakthroughs in this rapidly expanding field is key. The Sea Cucumber Apostichopus japonicus is essential to understanding the cultural underpinnings of the insatiable market demands for sea cucumber and what drives sea cucumber trade. It also provides biological information and aquaculture techniques that can be adapted to other species, making it a valuable resource for researchers and practitioners involved in sea cucumber harvesting, aquaculture, and conservation.
