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.

This new volume of Methods in Cell Biology looks at methods for analyzing centrosomes and centrioles. Chapters cover such topics as methods to analyze centrosomes, centriole biogenesis and function in multi-ciliated cells, laser manipulation of centrosomes or CLEM, analysis of centrosomes in human cancers and tissues, proximity interaction techniques to study centrosomes, and genome engineering for creating conditional alleles in human cells.

This book presents a biographical history of the field of systems thinking, by examining the life and work of thirty of its major thinkers. It discusses each thinker's key contributions, the way this contribution was expressed in practice and the relationship between their life and ideas. This discussion is supported by an extract from the thinker's own writing, to give a flavour of their work and to give readers a sense of which thinkers are most relevant to their own interests.

Whether you are watching an Eider soar low over the water or listening to the iconic sound of a flock of geese flying overhead, chances are you will already be familiar with many different species of ducks, geese and swans found around the UK. But can you tell a Goosander from a Red-breasted Merganser? Or confidently distinguish between a Pink-footed Goose and a Greylag Goose? The varied habitats in the British Isles provide a home to many ducks, geese and swans that live here year-round, as well as the enormous number of birds that arrive in winter. RSPB ID Spotlight Ducks, Geese and Swans is a reliable fold-out chart with illustrations of 30 of the UK's most familiar wildfowl by renowned artist Stephen Message. - Species are grouped by family and helpfully labelled to assist with identification - Artworks are shown side-by-side for quick comparison and easy reference at home or in the field - The reverse of the chart provides information on the habitats, behaviour, life cycles and diets of our ducks, geese and swans, as well as the conservation issues they are facing and how the RSPB is working to support them - Information on successful preservation campaigns of UK wetlands and how to take part in the Wetland Birds Survey is also included The ID Spotlight charts help wildlife enthusiasts identify and learn more about our most common species using accurate colour illustrations and informative, accessible text.
