Book Ecological Regions of North America

Download or read book Ecological Regions of North America written by and published by . This book was released on 1997 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.

Book Useful Plants of Neotropical Origin

Download or read book Useful Plants of Neotropical Origin written by Heinz Brücher and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with useful plants of neotropical origin, i.e., plants which have been cultivated in Southern and Central America as well as their wild relatives. Quite a number of these trees and bushes have "conquerred" the world as early as 400 years ago and are nowadays of utmost importance for feeding the increasing world population (e.g., potatoes). It has been estimated that about 150 such useful plants stem from the "New World." This book does not only describe the current theories about their domestication, cultivation, and evolution; it also discusses biotechnological methods for improving their productivity. About the German edition: ..". One of the most interesting and recurring themes of this book concerns some little-known species of potential value which may well become important to a future which is certain to present us with serious problems, at least as far as alimentation is considered. BrA1/4cher's book is absolutely up to date in the taxonomic and nomenclatural sense..." "Excerpta Botanica"#1

Book Ecophysiology of High Salinity Tolerant Plants

Download or read book Ecophysiology of High Salinity Tolerant Plants written by M. Ajmal Khan and published by Springer Science & Business Media. This book was released on 2006-05-16 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: The halophytes are highly specialized plants, which have greater tolerance to salt. They can germinate, grow and reproduce successfully in saline areas which would cause the death of regular plants. Most halophytic species are found in salt marsh systems along seashores or around landlocked inland lakes and flat plains with high evaporation. The halophytes play very significant role in the saline areas specially in the coast by overcoming the salinity in different ways, viz. with regulating mechanisms in which excess salts are excreted and with out regulating mechanism, which may include succulents or cumulative types. Besides that they protect coast from erosion and cyclones, provide feeding ground and nursery for fish, shrimps and birds. Halophytes get increasing attention today because of the steady increase of the salinity in irrigation systems in the arid and semi-arid regions where the increasing population reaches the limits of freshwater availability. In many countries, halophytes have been successfully grown on saline wasteland to provide animal fodder and have the potential for rehabilitation and even reclamation of these sites. The value of certain salt-tolerant grass species has been recognized by their incorporation in pasture improvement programs in many salt affected regions throughout the world. There have been recent advances in selecting species with high biomass and protein levels in combination with their ability to survive a wide range of environmental conditions, including salinity.

Available in PDF, EPUB and Kindle. Book excerpt: Found in a variety of forms, cacti and other succulents have elicited widespread interest and tremendous popularity worldwide. Although the subject of a certain amount of debate, about 10,000 species are recognized as belonging to the succulent group. Of these, an estimated 2,000 are threatened with global extinction in the wild and many more are regionally or nationally threatened mainly due to habitat destruction and collection for international trade.This Action Plan brings together from around the world current information on population status, threats and conservation of this particularly important group of plants. Prepared with conservationists, scientists, governments, protected area managers and grant-awarding bodies in mind, it suggests priorities for action and encourages collaboration among interested parties at all levels.

Book Changing Tides

Download or read book Changing Tides written by Barbara Neis and published by Fernwood Publishing. This book was released on 2005 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fisheries are among the most globalized economic sectors in the world. Relying largely on wild resources and employing millions of people and feeding many millions more, fisheries provide a unique vantage point from which to view contemporary globalization, which is co-occurring with a major ecological revolution triggered by resource degradation and associated with the development of intensive aquaculture. Globalization is intensifying the export orientation and use of joint ventures between rich and poor countries in fisheries. International organizations such as the IMF are pressuring many debtor countries to exchange access to their fishery resources for access to foreign exchange, constraining their ability to limit external ownership and the export of resources, and threatening local fishery employment and food self-sufficiency. Changing Tides brings together contributions from researchers and community workers from 13 countries of the world. Juxtaposing academic case studies with accounts from activists and fisheries workers, this book points the ways in which globalization and associated resource degradation, privatization and the concentration of ownership and control in fisheries are jeopardizing the lives and livelihoods of women fish workers and their families.

Book Archaeology of Manila Galleon Seaports and Early Maritime Globalization

Download or read book Archaeology of Manila Galleon Seaports and Early Maritime Globalization written by Chunming Wu and published by Springer Nature. This book was released on 2019-10-31 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the archaeological and historical research on the seaport heritage of galleon navigation in Asia-Pacific region. It reconstructs the Manila Galleons’ era of early maritime globalization, established and operated by Spanish navigators from the 16th to 19th centuries. The galleons sailed across the Pacific via the hub seaports and trade centers of Manila in the Philippines and Acapulco in Mexico, forming a prosperous sea route connecting eastern Asia and New Spain on the American continent for more than 250 years. This pioneering navigation of the pan-Pacific regions promoted early global maritime trade along the new Maritime Silk Road between the East and the West. Written by archaeologists and cultural historians from America, Mexico, Japan, the Philippines, Mainland China, Hong Kong and Taiwan, it presents the latest investigations and research on the galleon-affiliated seaports, including Acapulco and San Blas in Mexico, Guam, Manila in Philippines, Yuegang (Crescent Harbor), Xiamen (Amoy), Keelung and Macao in China, Nagasaki in Japan. This joint research sheds new light on the history of navigation and maritime trade between galleon-affiliated harbors; the origin, production, transport and trade of the galleon cargo; social cultural exchange along the new Maritime Silk Road in the pan-Pacific region; and the history of maritime globalization in last 500 years. It offers a new perspective on maritime archaeology and traces the different stages of the galleon trade and affiliated maritime history, including "Yuegang Outbound", "Manila Entrepotting" and "Bound for Acapulco", presenting a panoramagram of Spanish pan-Pacific trade and early maritime globalization.
