DOWNLOAD EBOOKThis book compiles for the first time the development of echinoderm research in Latin America. The book contains 17 chapters, one introductory, 15 country chapters, and a final biogeographic analysis. It compiles all the investigations published in international and local journals, reports, theses and other gray literature. Each chapter is composed of 7 sections: introduction describes the marine environments, and main oceanographic characteristics, followed by a history of research account divided by specific subjects. The next section addresses patterns of distribution and diversity. A specific section would explain fishery or aquaculture activities. The next sections deal with environmental and anthropogenic threats that are affecting echinoderm, and any conservation or management action. Finally, a section with conclusions, needs and new lines of research. The book will include two appendixes with species lists of all echinoderms with bathimetric data, habitat and distribution.

DOWNLOAD EBOOKLatin America and the Caribbean (LAC) region is exceptionally biodiverse. It contains about half of the world’s remaining tropical forests, nearly one-fifth of its coastal habitats, and some of its most productive agricultural and marine areas. But agriculture, fishing and other human activities linked to rapid population and economic growth increasingly threaten that biodiversity. Moreover, poverty, weak regulatory capacity, and limited political will hamper conservation. Given this dilemma, it is critically important to design conservation strategies on the basis of the best available information about both biodiversity and the track records of the various policies that have been used to protect it. This rigorously researched book has three key aims. It describes the status of biodiversity in LAC, the main threats to this biodiversity, and the drivers of these threats. It identifies the main policies being used to conserve biodiversity and assesses their effectiveness and potential for further implementation. It proposes five specific lines of practical action for conserving LAC biodiversity, based on: green agriculture; strengthening terrestrial protected areas and co-management; improving environmental governance; strengthening coastal and marine resource management; and improving biodiversity data and policy evaluation.

DOWNLOAD EBOOKThis fourth volume in the new multi-volume set Global Biodiversity is a rich resource on the biodiversity of a selection of countries in the Americas and in Australia. Chapters explore both wild and cultivated plants, wild and domesticated animals, and the variety of microbes of the countries of Bolivia, Brazil, Canada, Costa Rica, Cuba, Ecuador, Honduras, Mexico, Australia, Paraguay, the United States, and Venezuela. The different chapters explore the geographical status, ecosystem diversity, species diversity, genetic diversity, and conservation efforts in each selected country. They focus on genetic diversity of crop plants/cultivated plants and domesticated animals and their wild relatives and also discuss the endangered and protected plants and animals of the respective counties. Other volumes in this series include coverage of selected countries in Asia, Europe, and Africa. The volumes provide an informative compilation on the variety and variability of life in the regions discussed and will help to fill the gap in knowledge while also encouraging the conservation of biodiversity and sustainable utilization.

DOWNLOAD EBOOKWhat sight is more beautiful than a high-energy beach facing lines of rolling white breakers? What battleground is more ferocious than where waves and sand meet? What environment could be more exciting to study than this sandy interface between sea and land? And yet how much do we know about sandy beaches? Open sandy beaches are amongst the most neglected fields of scientific study in the coastal environment. This situation exists despite their great extent along most temperate and tropical coastlines and their value as recreational areas and buffer zones against the sea. The traditional oceanographer does not venture into the surf zone while the terrestrial ecologist stops short at the high water mark. Only a few coastal engineers have grappled with the problem of sand and sediment movement as it influences their construction of harbours and pipelines. The marine biologist on the other hand has regarded estuaries, coral reefs and rocky shores, obviously teeming with life, as more fruitful areas for study than the apparently poor animal life on sandy beaches. Sandy beaches have therefore tended to become a scientific no man's land. Over the last decade this situation has begun to improve. Recent work on high-energy beaches has revealed that they may in fact be rich and productive and fertile areas for study. It has even been suggested that beaches and their adjacent surf zones may constitute viable marine ecosystems.

DOWNLOAD EBOOKFocusing on Venezuela and Mexico, this edited volume from the International Society of Halophyte Utilisation (ISHU) explores the environmental issues facing South and Central America's coastal ecosystems, and discusses the uses of mangrove species and other halophytes in addressing issues of both coastal pollution and upland soil salinisation. The book presents a series of case studies and examines the economic potential of mangrove restoration and halophyte production.
