Download or read book The North American Geese written by Paul Johnsgard and published by Lulu.com. This book was released on 2016-08-23 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: The eight currently recognized species of North American geese are part of a familiar group of birds collectively called waterfowl, all of which are smaller than swans and generally larger than ducks. They include the most popular of our aquatic gamebirds, with several million shot each year by sport hunters. Our two most abundant waterfowl, the Canada goose and snow goose, have populations collectively totaling about 15 million individuals. Like swans, the lifelong pairbonding of geese, their familial care, and prolonged social attachment to their offspring are legendary. Their seasonal migratory flights sometimes span thousands of miles, and the sight of their long, wavering flight formations are as much the symbols of seasonal change as are the spring songs of cardinals or the appearance of autumnal leaf colors. This book describes each species' geographic range and subspecies, its identification traits, weights and measurements, and criteria for its age and sex determination. Ecological and behavioral information includes each species' breeding and wintering habitats, its foods and foraging behavior, its local and long distance movements, and its relationships with other species. Reproductive information includes each species' age of maturity, pair-bond pattern, pair-forming behaviors, usual clutch sizes and incubation periods, brooding behavior, and postbreeding behavior. Mortality sources and rates of egg, young, and adult losses are also summarized, and each species' past and current North American populations are estimated. In addition to a text of nearly 60,000 words, the book includes 8 maps, 21 line drawings, and 28 photographs by the author, as well as more than 700 literature citations.

Download or read book Environmental Aspects of Zoonotic Diseases written by Robert Armon and published by IWA Publishing. This book was released on 2012-01-31 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Aspects of Zoonotic Diseases provides a definitive description, commentary and research needs of environmental aspects related to zoonotic diseases. There are many interrelated connections between the environment and zoonotic diseases such as: water, soil, air and agriculture. The book presents investigations of these connections, with specific reference to environmental processes such as: deforestation, floods, draughts, irrigation practices, soil transfer and their impact on bacterial, viral, fungal, and parasitological spread. Environmental aspects such as climate (tropical, sub-tropical, temperate, arid and semi-arid), developed and undeveloped countries, animal (domestic and wild) traffic animal border crossing, commercial animal trade, transportation, as well geography and weather on zoonosis, are also discussed and relevant scientific data is condensed and organized in order to give a better picture of interrelationship between the environment and current spread of zoonotic diseases. Altogether, the book presents a remarkable and a vast amount of potential future research directions based on the link: environment-vectors-pathogens-humans. The most up-to-date source of information on this increasingly important cross-disciplinary subject, Environmental Aspects of Zoonotic Diseases will be invaluable for environmentalists, veterinarians, medical staff, environmental engineers, government agencies and consultants working in this field.

Download or read book American Holocaust written by David E. Stannard and published by Oxford University Press. This book was released on 1993-11-18 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: For four hundred years--from the first Spanish assaults against the Arawak people of Hispaniola in the 1490s to the U.S. Army's massacre of Sioux Indians at Wounded Knee in the 1890s--the indigenous inhabitants of North and South America endured an unending firestorm of violence. During that time the native population of the Western Hemisphere declined by as many as 100 million people. Indeed, as historian David E. Stannard argues in this stunning new book, the European and white American destruction of the native peoples of the Americas was the most massive act of genocide in the history of the world. Stannard begins with a portrait of the enormous richness and diversity of life in the Americas prior to Columbus's fateful voyage in 1492. He then follows the path of genocide from the Indies to Mexico and Central and South America, then north to Florida, Virginia, and New England, and finally out across the Great Plains and Southwest to California and the North Pacific Coast. Stannard reveals that wherever Europeans or white Americans went, the native people were caught between imported plagues and barbarous atrocities, typically resulting in the annihilation of 95 percent of their populations. What kind of people, he asks, do such horrendous things to others? His highly provocative answer: Christians. Digging deeply into ancient European and Christian attitudes toward sex, race, and war, he finds the cultural ground well prepared by the end of the Middle Ages for the centuries-long genocide campaign that Europeans and their descendants launched--and in places continue to wage--against the New World's original inhabitants. Advancing a thesis that is sure to create much controversy, Stannard contends that the perpetrators of the American Holocaust drew on the same ideological wellspring as did the later architects of the Nazi Holocaust. It is an ideology that remains dangerously alive today, he adds, and one that in recent years has surfaced in American justifications for large-scale military intervention in Southeast Asia and the Middle East. At once sweeping in scope and meticulously detailed, American Holocaust is a work of impassioned scholarship that is certain to ignite intense historical and moral debate.

Download or read book Sustainable Development and the Limitation of Growth written by Victor I. Danilov-Danil'yan and published by Springer Science & Business Media. This book was released on 2009-03-27 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: 2007 marked the 20th anniversary of the G.H.Brundtland Commission report that broke new ground by addressing the issue of sustainable development as a means of avoiding an ecological catastrophe. This led to a multitude of political declarations, documents and scientific articles while Agenda 21 – adopted in 1992 in Rio de Janeiro – has been accepted by the governments of more than 100 countries. Sadly, however, this has not prevented certain recent dangerous trends, nor have the wider public, journalists, business circles or politicians grasped the urgency of the problem. It is therefore important to make humanity understand its real place in the natural environment and the gravity of the ecological threat before us. The exclusive role of natural ecosystems is a key factor in the maintenance of the biospheric equilibrium. The current global crisis is largely caused by their dramatic decline by 43% in the past hundred years. Ignoring the immutable laws and limitations which determine the existence of all living things in the biosphere could lead humanity to an ecological catastrophe. This book presents the ecological, demographic, economic and socio-psychological manifestations of the global crisis and outlines the immutable laws and limitations which determine the existence of all living things in the biosphere.

This book was released on 2013-04-17 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: - A hypothesis is a proposition, set forth as an explanation for the occurrence of a phenomenon, that can be tested. - The basis for scientific investigation is the collection of information to formulate and test hypotheses. - Experimental methods measure the effect of manipulations caused by the investigator; observational methods collect information about naturally occurring events. - There are three sub-types of experimental techniques that differ in the way subjects are chosen for inclusion in the study, in the amount of control that the investigator has over variables, and in the method used to assess changes in other variables. - Descriptive observational studies dominate the early phase of most investigations and involve the description of disease-related events in the population. Associations among factors may be observed but the strength of the associations is not measured. - Analytical observation al techniques are of three basic types: prevalence surveys, case:control studies, and incidence or cohort studies. All attempt to explain the nature of relationships among various factors and to measure the strength of associations. - Prevalence surveys and case:control studies deal with disease existing at the time of the study; incidence studies are concerned with the development of disease over time. - Observational studies may be retrospective, using existing data, or prospective with collection of new information.
Download or read book Climate and Conservation written by Jodi A. Hilty and published by Island Press. This book was released on 2012-05-29 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate and Conservation presents case studies from around the world of leading-edge projects focused on climate change adaptation-regional-scale endeavors where scientists, managers, and practitioners are working to protect biodiversity by protecting landscapes and seascapes in response to threats posed by climate change. The book begins with an introductory section that frames the issues and takes a systematic look at planning for climate change adaptation. The nineteen chapters that follow examine particular case studies in every part of the world, including landscapes and seascapes from equatorial, temperate, montane, polar, and marine and freshwater regions. Projects profiled range from North American grasslands to boreal forests to coral reefs to Alpine freshwater environments. Chapter authors have extensive experience in their respective regions and are actively engaged in working on climate-related issues. The result is a collection of geographical case studies that allows for effective cross-comparison while at the same time recognizing the uniqueness of each situation and locale. Climate and Conservation offers readers tangible, place-based examples of projects designed to protect large landscapes as a means of conserving biodiversity in the face of the looming threat of global climate change. It informs readers of how a diverse set of conservation actors have been responding to climate change at a scale that matches the problem, and is an essential contribution for anyone involved with large-scale biodiversity conservation.
