The Maya Tropical Forest, which occupies the lowlands of southern Mexico, Guatemala, and Belize, is the closest rainforest to the United States and one of the most popular tourist destinations in the Western Hemisphere. It has been home to the Maya peoples for nearly four millennia, starting around 1800 BC. Ancient cities in the rainforest such as Palenque, Yaxchilan, Tikal, and Caracol draw thousands of tourists and scholars seeking to learn more about the prehistoric Maya. Their contemporary descendants, the modern Maya, utilize the forest's natural resources in village life and international trade, while striving to protect their homeland from deforestation and environmental degradation. Writing for both visitors and conservationists, James Nations tells the fascinating story of how ancient and modern Maya peoples have used and guarded the rich natural resources of the Maya Tropical Forest. He opens with a natural history that profiles the forest's significant animals and plants. Nations then describes the Maya peoples, biological preserves, and major archaeological sites in Mexico, Guatemala, and Belize. Drawing on more than twenty-five years of conservation work in the Maya Tropical Forest, Nations tells first-hand stories of the creation of national parks and other protected areas to safeguard the region's natural resources and archaeological heritage. He concludes with an expert assessment of the forest's future in which he calls for expanded archaeological tourism to create an ecologically sustainable economic base for the region.

Ecology of the Northern Lowland Bogs and Conifer Forests is a book on the ecology of bogs and conifer swamps and, to some extent, the marshlands. The chapters that follow are, for the most part, a review of what is known about the northern bogs and lowland forests, written in the terminology of science in the hope, as well as the expectation, that such knowledge will be of value to those who appreciate the beauty of bogs and marshlands, to ecologists and other biological scientists, naturalists, wildlife conservationists, hunters, trappers, construction engineers, as well as to others whose vocations or avocations take them afield. The discussion is devoted, at least primarily, to the ecology of one kind of wetland—the lowland bogs and conifer forests—and treats only in passing the marshlands and other kinds of vegetational communities that are also classified as wetlands. Of particular concern are the lowland peat bogs and forests, especially those that have developed to a point where their identity is indisputable for the simple reason that no other review of accumulated knowledge on these vegetational communities is presently available.
Large ungulates in tropical forests are among the most threatened taxa of mammals. Excessive hunting, degradation of and encroachments on their natural habitats by humans have contributed to drastic reductions in wild ungulate populations in recent decades. As such, reliable assessments of ungulate-habitat relationships and the spatial dynamics of their populations are urgently needed to provide a scientific basis for conservation efforts. However, such rigorous assessments are methodologically complex and logistically difficult, and consequently many commonly used ungulate population survey methods do not address key problems. As a result of such deficiencies, key parameters related to population distribution, abundance, habitat ecology and management of tropical forest ungulates remain poorly understood. This book addresses this critical knowledge gap by examining how population abundance patterns in five threatened species of large ungulates vary across space in the tropical forests of the Nagarahole-Bandipur reserves in southwestern India. It also explains the development and application of an innovative methodology – spatially explicit line transect sampling – based on an advanced hierarchical modelling under the Bayesian inferential framework, which overcomes common methodological deficiencies in current ungulate surveys. The methods and results presented provide valuable reference material for researchers and professionals involved in studying and managing wild ungulate populations around the globe.
Invasions of non-native plants into forests of the Southern United States continue to go unchecked and only partially un-monitored. These infestations increasingly erode forest productivity, hindering forest use and management activities, and degrading diversity and wildlife habitat. Often called non-native, exotic, non-indigenous, alien, or noxious weeds, they occur as trees, shrubs, vines, grasses, ferns, and forbs. This guide provides information on accurate identification of the 56 non-native plants and groups that are currently invading the forests of the 13 Southern States. In additin, it lists other non-native plants of growing concern. Illustrations. This is a print on demand edition of an important, hard-to-find publication.

The Boreal Ecosystem presents an overview of the state of knowledge on the boreal forest region of North America, with extensive reference to the boreal regions of Europe and Asia. Initial sections of this book deal with aspects of the floristic composition and evolutionary history of the boreal vegetation. These introduce subsequent discussions on the processes at work in vegetation, soils, and the atmosphere—in short, with the boreal forest as an ecosystem, the sum total of the influences of many closely interlaced biotic and physical factors. These include not only plant species that make up the visible vegetation but also nutrients, soil, temperature, rainfall, progression of the seasons, soil microflora, arthropods, insects, and larger animals such as marten, otter, beaver, moose, caribou, bear, and wolf, and man. All are closely linked strands in the web of life, a web apart from, yet dependent on and influencing, the raw physical environment. This book should serve as an introduction and reference source to its audience: undergraduate and graduate students in the biological and ecological disciplines, research workers in these fields as well as in related areas such as soil science, agronomy, genetics, and climatology; in short, everyone with an interest in boreal ecology.
John F. Kennedy: A Reference Guide to His Life and Works cover all aspects of his life and work. Despite his short tenure in office, Kennedy shaped the domestic and international direction of the nation for decades to come. He is remembered domestically for the hope and encouragement he instilled in the struggle for civil rights, his support for the freedom riders and for equality for women. Abroad, his memory lives in his handling of the Cold War against an aggressive Soviet Union and such events as the Berlin crisis and Wall, his intervention in the Vietnam War, the invasion of Cuba and Bay of Pigs disaster, the Cuban Missile crisis, and the beginnings of space exploration—all of which tested the young, relatively inexperienced, leader. Includes a detailed chronology detailing John F. Kennedy’s life, family, and work. The A to Z section includes family members, his handling of the Cold War, and such events as the Berlin crisis and Wall, his intervention in the Vietnam War, the invasion of Cuba and Bay of Pigs disaster, the Cuban Missile crisis, and the beginnings of space exploration. The bibliography includes a list of publications concerning his life and work. The index thoroughly cross-references the chronological and encyclopedic entries.
In today's world of specialization, people are attempting to protect the Earth's fragile state by swapping limousines for hybrids and pesticide-laced foods for organic produce. At other times, environmental awareness is translated into public relations gimmicks or trendy commodities. Moreover, simplistic policies, like single-species protection or planting ten trees for every tree cut down, are touted as bureaucratic or industrial panaceas. Because today's decisions are tomorrow's consequences, every small effort makes a difference, but a broader understanding of our environmental problems is necessary to the development of sustainable ecosystem policies. In Trees, Truffles, and Beasts, Chris Maser, Andrew W. Claridge, and James M. Trappe make a compelling case that we must first understand the complexity and interdependency of species and habitats from the microscopic level to the gigantic. Comparing forests in the Pacific Northwestern United States and Southeastern mainland of Australia, the authors show how easily observable speciesùtrees and mammalsùare part of a complicated infrastructure that includes fungi, lichens, and organisms invisible to the naked eye, such as microbes. Eminently readable, this important book shows that forests are far more complicated than most of us might think, which means simplistic policies will not save them. Understanding the biophysical intricacies of our life-support systems just might.
Professor Boyce s work is an excellent example of how ecological economics can be done in an objective, evidence-based approach that can put issues on the agenda in a manner where they will be taken seriously by other scholars. . . This is a well-written and provocative book that should encourage further research on all these important issues. David I. Stern, International Journal of Social Economics This succinct and sometimes provocative book sets out to document, quantify and explain the ways in which inequalities of wealth and power create an uneven apportionment of environmental costs across the world. It offers a combination of theoretical analysis and empirical evidence to support the author s central contention that greater democratisation and changes in society s relationship with nature are paramount for achieving the dual goals of environmental protection and sustainable development. . . This book is immensely well written. . . makes for a fascinating read. Ian Bailey, European Spatial Research and Policy Economic activities that degrade the environment do not simply pit humans against nature. They also pit some humans against others. Some benefit from these activities; others bear net costs from pollution and resource depletion. In a provocative and original analysis, James K. Boyce examines the dynamics of environmental degradation in terms of the balances of power between the winners and the losers. He provides evidence that inequalities of power and wealth affect not only the distribution of environmental costs, but also their overall magnitude: greater inequalities result in more environmental degradation. Democratization movement toward a more equitable distribution of power therefore is not only a worthwhile objective in its own right, but also an important means toward the social goals of environmental protection and sustainable development. Combining theoretical analysis with empirical evidence from around the world, James K. Boyce demonstrates that changes in our relationship with nature ultimately require changes in our relationships with each other. He maintains that a more democratic and environmentally sustainable future is possible, but warns that it is not inevitable. This book will appeal to students, scholars, policymakers and other readers interested in the environment, economics and public policy.
As America tries to deal with the consequences of its misfired Iraq expedition and the host of other challenges lurking in a murky future, this book will sharpen our thoughts on the uses and misuses of the UN and where it fits into Washington policies. The authors suggest an approach and specific policy elements that merit serious attention, even as they make clear they do not expect the UN will be any kind of panacea." -Morton Abramowitz, Senior Fellow at The Century Foundation By the same authors: The Third Try: can the UN work? Published in Australia by Scribe Books in 2005, The Third Try was selected for the short list of a prestigious New South Wales Literary Prize. The German translation, by Dr Michael Haupt, was released in 2006 by Parthas Verlag in Berlin. from Third Try Australian reviews: ".a brilliant analysis of an often maligned organization that pledged international kinship and is struggling to reinvent itself to stand for something meaningful. An extremely significant book that is sure to rouse the public from its slumber. Five stars." -Tony O'Loughlin, Australian Bookseller & Publisher, October 2005 ".written for the lay reader and is set out in a clear, straightforward style . Its accessible manner makes welcome reading when facing such a daunting subject." -Chris Saliba, WebDiary
First published in 1988. Livestock poisoning by plants has been a problem to the livestock producers of the United States since our pioneer forefathers first grazed their herds of cattle and sheep on the vast rangelands and pastures of this country. It has long been recognized that poisonous plants are not only disruptive to the harvesting of the
This monograph is about blue grouse (Dendragapus obscurus). Designed as a reference work, it documents and reviews much of what is known about the biology and natural history of this bird. It is based primarily on our published and unpublished long-term studies in British Columbia and elsewhere, and on the studies of others in various parts of the bird's range.

Researchers and managers of regulated river systems will find this volume useful in acquiring information for deciding an integrated management plan for regulated river operations. Rather than the ecological theory of impacts of flow regulation, emphasis has been placed on methods to predict water quality and habitat alterations, as well as techniques to mitigate impacts from various operational scenarios. Although most chapters refer to impacts of riverine impoundments, these alternatives apply to any regulated situation in which changes in water quality or flow pattern occur. The predictive modeling techniques are explained primarily from a theoretical background. However, extensive bibliographies can guide the uninitiated to specific texts and software. Where controversial techniques have been presented, alternate methods are also described. Major topic areas include water quality problems, channel modification and management, ecological modeling and management, as well as a section on perspectives for ecological management and special problems in developing nations.
