This book was released on 2011 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Raccoons (Procyon lotor), striped skunks (Mephitis mephitis), and Virginia opossums (Didelphis virginiana) comprise a community of ecological generalists that coexist throughout their ranges in North America and utilize many of the same resources. These sympatric omnivores occur in a variety of habitats and can have significant impacts on the communities and ecosystems in which they occur, such as influencing avifaunal communities and hosting and transmitting diseases. Yet, relatively few studies have examined the spatial correlates that may allow their coexistence. Space-use patterns, including home range, habitat use, movements, and relative abundances can all be mechanisms by which these species might coexist. A study with three main components was conducted to determine space-use patterns of raccoon, striped skunk, and Virginia opossum on a 1,200 ha study site in Angelina County, Texas, USA, from December 2008-May 2010. The study site is surrounded by two channels of the Neches River and is dominated by mature bottomland hardwood forest and mature, thinned loblolly pine ( Pinus taeda) stands. The site is managed for timber production and white-tailed deer (Odocoileus virginianus) hunting.

This book was released on 2005 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Virginia opossum, (Didelphis virginiana), and the Northern raccoon, (Procyon lotor), both mesopredators, are common inhabitants of the Pineywoods eco-region of East Texas. The Pineywoods landscape historically was comprised of large tracts of contiguous forest, but has been altered and now consists of a matrix of forested patches adjacent to cultivated fields and suburban areas. This habitat fragmentation, resulting from the timber industry and suburban sprawl, has increased the ratio of edge habitat to interior habitat in remaining forest patches. The home range size and habitat use of the opossum and raccoon in this fragmented landscape was studied using radio telemetry and global information systems analysis. Home range size for the opossum and raccoon were similar to previous studies. Two opossums exhibited a possible preference for proximity to roads, while two raccoons exhibited a possible edge preference. The remaining raccoon exhibited no statistical difference in proximity to a road or edge than from random points.

Download or read book Public Health Significance of Urban Pests written by Xavier Bonnefoy and published by World Health Organization. This book was released on 2008 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second half of the 20th century and the beginning of the 21st century witnessed important changes in ecology, climate and human behaviour that favoured the development of urban pests. Most alarmingly, urban planners now face the dramatic expansion of urban sprawl, in which city suburbs are growing into the natural habitats of ticks, rodents and other pests. Also, many city managers now erroneously assume that pest-borne diseases are relics of the past. All these changes make timely a new analysis of the direct and indirect effects of present-day urban pests on health. Such an analysis should lead to the development of strategies to manage them and reduce the risk of exposure. To this end, WHO invited international experts in various fields - pests, pest-related diseases and pest management - to provide evidence on which to base policies. These experts identified the public health risk posed by various pests and appropriate measures to prevent and control them. This book presents their conclusions and formulates policy options for all levels of decision-making to manage pests and pest-related diseases in the future. [Ed.]
Download or read book People and Predators written by Defenders of Wildlife and published by Island Press. This book was released on 2012-06-22 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carnivores provide innumerable ecological benefits and play a unique role in preserving and maintaining ecosystem services and function, but at the same time they can create serious problems for human populations. A key question for conservation biologists and wildlife managers is how to manage the world's carnivore populations to conserve this important natural resource while mitigating harmful impacts on humans. In People and Predators, leading scientists and researchers offer case studies of human-carnivore conflicts in a variety of landscapes, including rural, urban, and political. The book covers a diverse range of taxa, geographic regions, and conflict scenarios, with each chapter dealing with a specific facet of human-carnivore interactions and offering practical, concrete approaches to resolving the conflict under consideration. Chapters provide background on particular problems and describe how challenges have been met or what research or tools are still needed to resolve the conflicts. People and Predators will helps readers to better understand issues of carnivore conservation in the 21st century, and provides practical tools for resolving many of the problems that stand between us and a future in which carnivores fulfill their historic ecological roles.
Download or read book Conservation by Proxy written by Tim Caro and published by Island Press. This book was released on 2010-06-23 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast scope of conservation problems has forced biologists and managers to rely on "surrogate" species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health. Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utility, and makes recommendations for their continued use. The book clarifies terminology and contrasts how different terms are used in the real world considers the ecological, taxonomic, and political underpinnings of these shortcuts identifies criteria that make for good surrogate species outlines the circumstances where the application of the surrogate species concept shows promise Conservation by Proxy is a benchmark reference that provides clear definitions and common understanding of the evidence and theory behind surrogate species. It is the first book to review and bring together literature on more than fifteen types of surrogate species, enabling us to assess their role in conservation and offering guidelines on how they can be used most effectively.
Download or read book The Connections Between Ecology and Infectious Disease written by Christon J. Hurst and published by Springer. This book was released on 2018-08-30 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes current advances in our understanding of how infectious disease represents an ecological interaction between a pathogenic microorganism and the host species in which that microbe causes illness. The contributing authors explain that pathogenic microorganisms often also have broader ecological connections, which can include a natural environmental presence; possible transmission by vehicles such as air, water, and food; and interactions with other host species, including vectors for which the microbe either may or may not be pathogenic. This field of science has been dubbed disease ecology, and the chapters that examine it have been grouped into three sections. The first section introduces both the role of biological community interactions and the impact of biodiversity on infectious disease. In turn, the second section considers those diseases directly affecting humans, with a focus on waterborne and foodborne illnesses, while also examining the critical aspect of microbial biofilms. Lastly, the third section presents the ecology of infectious diseases from the perspective of their impact on mammalian livestock and wildlife as well as on humans. Given its breadth of coverage, the volume offers a valuable resource for microbial ecologists and biomedical scientists alike.
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.

Book excerpt: The New York Times bestseller A New York Times Notable and Critics’ Top Book of 2016 Longlisted for the PEN/John Kenneth Galbraith Award for Nonfiction One of NPR's 10 Best Books Of 2016 Faced Tough Topics Head On NPR's Book Concierge Guide To 2016’s Great Reads San Francisco Chronicle's Best of 2016: 100 recommended books A Washington Post Notable Nonfiction Book of 2016 Globe & Mail 100 Best of 2016 “Formidable and truth-dealing . . . necessary.” —The New York Times “This eye-opening investigation into our country’s entrenched social hierarchy is acutely relevant.” —O Magazine In her groundbreaking bestselling history of the class system in America, Nancy Isenberg upends history as we know it by taking on our comforting myths about equality and uncovering the crucial legacy of the ever-present, always embarrassing—if occasionally entertaining—poor white trash. “When you turn an election into a three-ring circus, there’s always a chance that the dancing bear will win,” says Isenberg of the political climate surrounding Sarah Palin. And we recognize how right she is today. Yet the voters who boosted Trump all the way to the White House have been a permanent part of our American fabric, argues Isenberg. The wretched and landless poor have existed from the time of the earliest British colonial settlement to today's hillbillies. They were alternately known as “waste people,” “offals,” “rubbish,” “lazy lubbers,” and “crackers.” By the 1850s, the downtrodden included so-called “clay eaters” and “sandhillers,” known for prematurely aged children distinguished by their yellowish skin, ragged clothing, and listless minds. Surveying political rhetoric and policy, popular literature and scientific theories over four hundred years, Isenberg upends assumptions about America’s supposedly class-free society––where liberty and hard work were meant to ensure real social mobility. Poor whites were central to the rise of the Republican Party in the early nineteenth century, and the Civil War itself was fought over class issues nearly as much as it was fought over slavery. Reconstruction pitted poor white trash against newly freed slaves, which factored in the rise of eugenics–-a widely popular movement embraced by Theodore Roosevelt that targeted poor whites for sterilization. These poor were at the heart of New Deal reforms and LBJ’s Great Society; they haunt us in reality TV shows like Here Comes Honey Boo Boo and Duck Dynasty. Marginalized as a class, white trash have always been at or near the center of major political debates over the character of the American identity. We acknowledge racial injustice as an ugly stain on our nation’s history. With Isenberg’s landmark book, we will have to face the truth about the enduring, malevolent nature of class as well.

Download or read book 50 Years of Bat Research written by Burton K. Lim and published by Springer Nature. This book was released on 2021-01-23 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: With more than 1,400 species, bats are an incredibly diverse and successful group of mammals that can serve as model systems for many unique evolutionary adaptations. Flight has allowed them to master the sky, while echolocation enables them to navigate in the dark. Being small, secretive, nocturnal creatures has made bats a challenge to study, but over the past 50 years, innovative research has made it possible to dispel some of the mystery and myth surrounding them to give us a better understanding of the role these animals play in the ecosystem. The structure of the book is based on several broad themes across the biological sciences, including the evolution of bats, their ecology and behavior, and conservation of biodiversity. Within these themes are more specific topics on important aspects of bat research, such as morphology, molecular biology, echolocation, taxonomy, systematics, threats to bats, social structure, reproduction, movements, and feeding strategies. Given its scope, the book will appeal to the wider scientific community, environmental organizations, and government policymakers who are interested in the interdisciplinary aspects of biology and nature.
Download or read book Southwestern Desert Resources written by William L. Halvorson and published by University of Arizona Press. This book was released on 2023-01-17 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: The southwestern deserts stretch from southeastern California to west Texas and then south to central Mexico. The landscape of this region is known as basin and range topography featuring to “sky islands” of forest rising from the desert lowlands which creates a uniquely diverse ecology. The region is further complicated by an international border, where governments have caused difficulties for many animal populations. This book puts a spotlight on individual research projects which are specific examples of work being done in the area and when they are all brought together, to shed a general light of understanding the biological and cultural resources of this vast region so that those same resources can be managed as effectively and efficiently as possible. The intent is to show that collaborative efforts among federal, state agency, university, and private sector researchers working with land managers, provides better science and better management than when scientists and land managers work independently.
