Coastal and marine ecosystems, some severely degraded, other still pristine, control rich resources of inshore environments and coastal seas of Latin America's Pacific and Atlantic margins. Conflicts between the needs of the region's nations and diminishing revenues and environmental quality have induced awareness of coastal ecological problems and motivated financial support for restoration and management. The volume provides a competent review on the structure, processes and function of 22 important Latin American coastal marine ecosystems. Each contribution describes the environmental settings, biotic components and structure of the system, considers trophic processes and energy flow, evaluates the modifying influence of natural and human perturbations, and suggests management needs. Although the focus of the book is on basic ecological research, the results have application for coastal managers.

Along The River that Flows Uphill weaves the story of an Amazon journey with science, math and reason to explore the risks that are inherent in adventure travel. In 2005, Geographical - the official magazine of the Royal Geographical Society in London - commissioned authors Richard Starks and Miriam Murcutt to write an article about a strange river in Venezuela called the Casiquiare. This river - once the source of great controversy until it was explored by Alexander von Humboldt - is like no other, since it joins two, otherwise-separate river systems, the Orinoco and the Amazon, by apparently flowing up and over the watershed that divides them.Rivers are not meant to do that. For Richard Starks - an award-winning journalist, author and traveler - the writing commission offered a chance to test himself against the standards set by his childhood explorer-heroes - men like Burton, Speke, Livingstone and Stanley. For Miriam Murcutt - a writer, editor and former marketing executive - it represented a chance for adventure. The two writers hired a boat and a guide to take them 1,000 miles up the Orinoco and along the Casiquiare to the Rio Negro, which flows into the Amazon. They expected to travel only with their guide, but once on board his boat, they found he'd brought along his extended family, as well as a group of researchers that included a young and overly persistent entomologist. A few days into the journey, the boat took on another passenger - a Yanomami Indian from a primitive tribe that is reputedly among 'the most violent people on Earth'. Further up river, FARC guerillas tried to hold the authors for ransom when they strayed over the border into Columbia. Along the River that Flows Uphill is more than an account of the authors' journey. It blends their travels with the contentious history and peculiar geography of the Casiquiare. And it examines the society and culture of the Yanomami Indians who live alongside it. The book is also a story of self-discovery. And it assesses risk - not just the risk that's part of all adventure travel, but also, by extension, the risk that's inherent in the adventure of life.

The Amazon and Orinoco basins in northern South America are home to the highest concentration of freshwater fish species on earth, with more than 3,000 species allotted to 564 genera. Amazonian fishes include piranhas, electric eels, freshwater stingrays, a myriad of beautiful small-bodied tetras and catfishes, and the largest scaled freshwater fish in the world, the pirarucu. Field Guide to the Fishes of the Amazon, Orinoco, and Guianas provides descriptions and identification keys for all the known genera of fishes that inhabit Greater Amazonia, a vast and still mostly remote region of tropical rainforests, seasonally flooded savannas, and meandering lowland rivers. The guide’s contributors include more than fifty expert scientists. They summarize the current state of knowledge on the taxonomy, species richness, and ecology of these fish groups, and provide references to relevant literature for species-level identifications. This richly illustrated guide contains 700 detailed drawings, 190 color photos, and 500 distribution maps, which cover all genera. An extensive and illustrated glossary helps readers with the identification keys. The first complete overview of the fish diversity in the Amazon, Orinoco, and Guianas, this comprehensive guide is essential for anyone interested in the freshwater life inhabiting this part of the world.

There is a growing need for appropriate management of aquatic plants in rivers and canals, lakes and reservoirs, and drainage channels and urban waterways. This management must be based on a sound knowledge of the ecology of freshwater plants, their distribution and the different forms of control available including chemical, physical, biological and biomanipulation. This series of papers from over 20 different countries was generated from the highly successful European Weed Research Society symposia on aquatic plant management, this being the ninth. The contributions provide a valuable insight into the complexities involved in managing aquatic systems, discuss state-of-the-art control techniques such as biomanipulation using fish and waterfowl and the use of straw, and deal with patterns of regrowth and recovery post-management. Careful consideration is given to the use of chemicals, a practice which has come under scrutiny in recent years. Underpinning the development of such control techniques is a growing body of knowledge relating to the biology and ecology of water plants, including growth responses under different trophic conditions, the impact of pollution, and aspects of photosynthesis. The authorship of the papers represents the collective wisdom of leading scientists and experts from fisheries agencies, river authorities, nature conservation agencies, the agrochemical industry and both governmental and non-governmental organisations.
