This book was released on 2001 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Download or read book Amazonia Without Myths written by Commission on Development and Environment for Amazonia and published by The Minerva Group, Inc.. This book was released on 2001-12 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report, prepared by the Commission on Development and Environment for Amazonia at the initiative of the Amazon Cooperation Treaty and supported by the Inter-American Development Bank and the United Nations Development Programme, is based on the concept of an Amazonia that exists above and beyond the world of fantasy and myth: an Amazonia of flesh and blood, of human toil, of human history, of human faces and hopes, and future human beings. It is an analysis based not only on the experiences and technologies of today"s world but also, and with greater emphasis, on the wisdom accumulated for centuries by Amazonia itself: standing Amazonia. The Amazon region has the largest area of tropical forest on the planet, and concern for its environmental deterioration extends well beyond the borders of the eight countries that form a part of it. With support from the IDB and UNDP, the Commission on Development and Environment for Amazonia prepared this report that provides data on the region's natural resources, population, health and infrastructure.

Download or read book Fire Ecology and Management Past Present and Future of US Forested Ecosystems written by Cathryn H. Greenberg and published by Springer Nature. This book was released on 2021-10-01 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume presents original scientific research and knowledge synthesis covering the past, present, and potential future fire ecology of major US forest types, with implications for forest management in a changing climate. The editors and authors highlight broad patterns among ecoregions and forest types, as well as detailed information for individual ecoregions, for fire frequencies and severities, fire effects on tree mortality and regeneration, and levels of fire-dependency by plant and animal communities. The foreword addresses emerging ecological and fire management challenges for forests, in relation to sustainable development goals as highlighted in recent government reports. An introductory chapter highlights patterns of variation in frequencies, severities, scales, and spatial patterns of fire across ecoregions and among forested ecosystems across the US in relation to climate, fuels, topography and soils, ignition sources (lightning or anthropogenic), and vegetation. Separate chapters by respected experts delve into the fire ecology of major forest types within US ecoregions, with a focus on the level of plant and animal fire-dependency, and the role of fire in maintaining forest composition and structure. The regional chapters also include discussion of historic natural (lightning-ignited) and anthropogenic (Native American; settlers) fire regimes, current fire regimes as influenced by recent decades of fire suppression and land use history, and fire management in relation to ecosystem integrity and restoration, wildfire threat, and climate change. The summary chapter combines the major points of each chapter, in a synthesis of US-wide fire ecology and forest management into the future. This book provides current, organized, readily accessible information for the conservation community, land managers, scientists, students and educators, and others interested in how fire behavior and effects on structure and composition differ among ecoregions and forest types, and what that means for forest management today and in the future.

Download or read book Fire and Climatic Change in Temperate Ecosystems of the Western Americas written by Thomas T. Veblen and published by Springer Science & Business Media. This book was released on 2006-05-10 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both fire and climatic variability have monumental impacts on the dynamics of temperate ecosystems. These impacts can sometimes be extreme or devastating as seen in recent El Nino/La Nina cycles and in uncontrolled fire occurrences. This volume brings together research conducted in western North and South America, areas of a great deal of collaborative work on the influence of people and climate change on fire regimes. In order to give perspective to patterns of change over time, it emphasizes the integration of paleoecological studies with studies of modern ecosystems. Data from a range of spatial scales, from individual plants to communities and ecosystems to landscape and regional levels, are included. Contributions come from fire ecology, paleoecology, biogeography, paleoclimatology, landscape and ecosystem ecology, ecological modeling, forest management, plant community ecology and plant morphology. The book gives a synthetic overview of methods, data and simulation models for evaluating fire regime processes in forests, shrublands and woodlands and assembles case studies of fire, climate and land use histories. The unique approach of this book gives researchers the benefits of a north-south comparison as well as the integration of paleoecological histories, current ecosystem dynamics and modeling of future changes.
Download or read book Defending the Land of the Jaguar written by Lane Simonian and published by University of Texas Press. This book was released on 1995 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexican conservationists have sometimes observed that it is difficult to find a country less interested in the conservation of its natural resources than is Mexico. Yet, despite a long history dedicated to the pursuit of development regardless of its environmental consequences, Mexico has an equally long, though much less developed and appreciated, tradition of environmental conservation. Lane Simonian here offers the first panoramic history of conservation in Mexico from pre-contact times to the current Mexican environmental movement. He explores the origins of conservation and environmental concerns in Mexico, the philosophies and endeavors of Mexican conservationists, and the enactment of important conservation laws and programs. This heretofore untold story, drawn from interviews with leading Mexican conservationists as well as archival research, will be important reading throughout the international community of activists, researchers, and concerned citizens interested in the intertwined issues of conservation and development.
Download or read book Soil Quality for Crop Production and Ecosystem Health written by E.G. Gregorich and published by Elsevier. This book was released on 1997-11-10 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is a complex body that exists as many types, each with diverse properties that may vary widely across time and space as a function of many factors. This complexity makes the evaluation of soil quality much more challenging than that of water or air quality. Evaluation of soil quality now considers environmental implications as well as economic productivity, seeking to be more holistic in its approach.Thus, soil quality research draws from a wide range of disciplines, blending the approaches of biologists, physicists, chemists, ecologists, economists and agronomists, among others.This book presents a broad perspective of soil quality that includes these various perspectives and gives a strong theoretical basis for the assessment of soil quality.A short glossary provides definitions for terms used throughout the book.
Download or read book Tropical Fire Ecology written by Mark Cochrane and published by Springer Science & Business Media. This book was released on 2010-04-11 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tropics are home to most of the world’s biodiversity and are currently the frontier for human settlement. Tropical ecosystems are being converted to agricultural and other land uses at unprecedented rates. Land conversion and maintenance almost always rely on fire and, because of this, fire is now more prevalent in the tropics than anywhere else on Earth. Despite pervasive fire, human settlement and threatened biodiversity, there is little comprehensive information available on fire and its effects in tropical ecosystems. Tropical deforestation, especially in rainforests, has been widely documented for many years. Forests are cut down and allowed to dry before being burned to remove biomass and release nutrients to grow crops. However, fires do not always stop at the borders of cleared forests. Tremendously damaging fires are increasingly spreading into forests that were never evolutionarily prepared for wild fires. The largest fires on the planet in recent decades have occurred in tropical forests and burned millions of hectares in several countries. The numerous ecosystems of the tropics have differing levels of fire resistance, resilience or dependence. At present, there is little appreciation of the seriousness of the wild fire situation in tropical rainforests but there is even less understanding of the role that fire plays in the ecology of many fire adapted tropical ecosystems, such as savannas, grasslands and other forest types.
Download or read book The Geology of Chile written by Teresa Moreno (Ph. D.) and published by Geological Society of London. This book was released on 2007 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first comprehensive account in English of the geology of Chile, providing a key reference work that brings together many years of research, and written mostly by Chilean authors from various universities and other centres of research excellence. The 13 chapters begin with a general overview, followed by detailed accounts of Andean tectonostratigraphy and magmatism, the amazingly active volcanism, the world class ore deposits that have proven to be so critical to the welfare of the country, and Chilean water resources. The subject then turns to geophysics with an examination of neotectonics and earthquakes, the hazardous frequency of which is a daily fact of life for the Chilean population. There are chapters on the offshore geology and oceanography of the SE Pacific Ocean, subjects that continue to attract much research not least from those seeking to understand world climatic variations, and on late Quaternary land environments, concluding with an account examining human colonization of southernmost America. The geological evolution of Chile is the c. 550 million year history of a continental margin over 4000 km long. During his voyage on H.M.S. Beagle, an extended visit to Chile (1834-35) had a profound impact on Charles Darwin, especially on his understanding of volcanoes, earthquakes and tsunamis.

Download or read book Primates in Fragments written by Laura K. Marsh and published by Springer Science & Business Media. This book was released on 2013-09-07 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is number two in a series for Primates in Fragments. In this volume, ten years after the first http://www.springer.com/social+sciences/anthropology+%26+archaeology/book/978-0-306-47696-9, we continue to address issues regarding primates within a fractured landscape. There are seven sections based on specific categories of primates in fragments. In the Introductory section, authors discuss the issues surrounding primates in remnant habitats as well as encourage discussion about what we mean by fragmentation on a landscape scale. In the Long-Term and Regional Studies section, authors present information on changes that have occurred during longer studies as well as changes that have occurred over regions. In the Landscape, Metapopulations and the Matrix section, authors cover topics from dry to moist forests, and from metapopulations to single species use of multiple fragments locations. In Feeding and Behavioral Ecology, authors take a closer look at the flexibility and responsiveness of primates in fragments in terms of their food choices, resource use, and behavioral changes. In Endemic, Endangered, and Nocturnal Primates authors uncover details involving critical primates living in major city centers to the heights of the Himalayas. In Genetics, Disease and Parasites authors cover topics including population viability, disease and parasite transmission between primates in fragments and humans. Finally, in the Conservation and Ecology: Threats and Management section, we synthesize information in this volume and make recommendations for the future of work in this field and the survivability of primates in fragments.
Download or read book Primates in Fragments written by Laura K. Marsh and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume was created initially from a symposium of the same name presented at the International Primatological Society's XVIII Congress in Adelaide. South Australia. 6-12 January 2000. Many of the authors who have contributed to this text could not attend the symposium. so this has become another vehicle for the rapidly growing discipline of Fragmentation Science among primatologists. Fragmentation has quickly become a field separate from general ecology. which underscores the severity of the situation since we as a planet are rapidly losing habitat of all types to human disturbance. Getting ecologists. particularly primatologists. to admit that they study in fragments is not easy. In the field of primatology. one studies many things. but rarely do those things (genetics. behavior. population dynamics) get called out as studies in fragmentation. For some reason "fragmentation primatologists" fear that our work is somehow "not as good" as those who study in continuous habitat. We worry that perhaps our subjects are not demonstrating as robust behaviors as they "should" given fragmented or disturbed habitat conditions. I had a colleague openly state that she did not work in fragmented forests. that she merely studied behavior when it was clear that her study sites. everyone of them. was isolated habitat. Our desire to be just another link in the data chain for wild primates is so strong that it makes us deny what kinds of habitats we are working in. However.
