Tropical Stream Ecology describes the main features of tropical streams and their ecology. It covers the major physico-chemical features, important processes such as primary production and organic-matter transformation, as well as the main groups of consumers: invertebrates, fishes and other vertebrates. Information on concepts and paradigms developed in north-temperate latitudes and how they do not match the reality of ecosystems further south is expertly addressed. The pressing matter of conservation of tropical streams and their biodiversity is included in almost every chapter, with a final chapter providing a synthesis on conservation issues. For the first time, Tropical Stream Ecology places an important emphasis on viewing research carried out in contributions from international literature. - First synthetic account of the ecology of all types of tropical streams - Covers all of the major tropical regions - Detailed consideration of possible fundamental differences between tropical and temperate stream ecosystems - Threats faced by tropical stream ecosystems and possible conservation actions - Descriptions and synstheses life-histories and breeding patterns of major aquatic consumers (fishes, invertebrates)

The end of the 16th century saw Dutch expansion in Asia, as The Dutch East India Company (the VOC) was fast becoming an Asian power, both political and economic. By 1669, the VOC was the richest private company the world had ever seen. This landmark study looks at perhaps the most important tool in the Company' trading - its ships. In order to reconstruct the complete shipping activities of the VOC, the author created a unique database of the ships' movements, including frigates and other, hitherto ingored, smaller vessels. Parthesius's research into the routes and the types of ships in the service of the VOC proves that it was precisely the wide range of types and sizes of vessels that gave the Company the ability to sail - and continue its profitable trade - the year round. Furthermore, it appears that the VOC commanded at least twice the number of ships than earlier historians have ascertained. Combining the best of maritime and social history, this book will change our understanding of the commercial dynamics of the most successful economic organization of the period.

This landmark scientific reference for scientists, researchers, and students of marine biology tackles the monumental task of taking a complete biodiversity inventory of the Gulf of Mexico with full biotic and biogeographic information. Presenting a comprehensive summary of knowledge of Gulf biota through 2004, the book includes seventy-seven chapters, which list more than fifteen thousand species in thirty-eight phyla or divisions and were written by 138 authors from seventy-one institutions in fourteen countries.This first volume of Gulf of Mexico Origin, Waters, and Biota, a multivolumed set edited by John W. Tunnell Jr., Darryl L. Felder, and Sylvia A. Earle, provides information on each species' habitat, biology, and geographic range, along with full references and a narrative introduction to the group, which opens each chapter.
