Book Impacts of Rural Development on Puma Ecology in California s Sierra Nevada

Download or read book Impacts of Rural Development on Puma Ecology in California s Sierra Nevada written by Anne M. Orlando and published by . This book was released on 2008 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In Western North America, many rural areas are being converted to ranchette-style residential development (2-16+-ha plots), potentially degrading habitat for large carnivores including pumas (Puma concolor, also known as cougars or mountain lions), and impacting ecosystem integrity. In a rapidly developing rural region of California's Western Sierra Nevada, I studied the impacts of low-density development on puma habitat utility, behavioral ecology, mortality, and viability. I characterized properties experiencing puma depredation, a major puma mortality cause in the study region, and compared attributes of properties that had, and had not, experienced depredation. Most depredations (67%) occurred on ranchette-sized parcels and hobby farms, while 3 professional ranches (2.9% of properties experiencing puma depredations) accounted for a disproportionate share (17%) of depredations and pumas killed (23%). Numbers and densities of goats and sheep most strongly predicted puma depredation on a property, followed by geographic features including high slope and elevation, brushy cover, and proximity to rivers and national forests. I then investigated whether rural development reduced puma habitat utility by examining habitat use and movement parameters from GPS-collared pumas in undeveloped and developed rural areas of the same ecosystem. Development appeared to limit habitat utility, with pumas in the developed zone occupying smaller, less round home ranges than undeveloped zone animals. Unlike undeveloped zone pumas, developed zone animals avoided roads and appeared to use riparian areas as movement corridors, and steep-sided canyons bordering residential areas for rest and feeding cover. Finally, I examined whether rural development functionally fragmented puma habitat at the population, landscape, and individual scales. Dispersal and survival parameters, including a high developed zone mortality rate (42.9%), suggested a "source-sink" population structure. Pumas crossed highways 7.9 times less and housing developments 3.7 times less than expected, and these obstacles threatened to disrupt landscape connectivity. Within their home ranges, pumas avoided developed areas (d"0-acre parcels) and preferentially used less developed areas (>40-acre parcels), especially during the day. Low-density rural development exacerbated puma depredation and mortality, constrained habitat utility, and fragmented habitat. Conserving pumas and associated wildlife communities will require efforts to reduce human-caused mortality, protect corridors, retain open spaces, preserve source populations, and limit anthropogenic obstacles to landscape connectivity."--Abstract

  • ISBN : 0128016876
  • Pages : 468 pages

Download or read book Sea Otter Conservation written by Shawn Larson and published by Academic Press. This book was released on 2014-12-23 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea otters are good indicators of ocean health. In addition, they are a keystone species, offering a stabilizing effect on ecosystem, controlling sea urchin populations that would otherwise inflict damage to kelp forest ecosystems. The kelp forest ecosystem is crucial for marine organisms and contains coastal erosion. With the concerns about the imperiled status of sea otter populations in California, Aleutian Archipelago and coastal areas of Russia and Japan, the last several years have shown growth of interest culturally and politically in the status and preservation of sea otter populations. Sea Otter Conservation brings together the vast knowledge of well-respected leaders in the field, offering insight into the more than 100 years of conservation and research that have resulted in recovery from near extinction. This publication assesses the issues influencing prospects for continued conservation and recovery of the sea otter populations and provides insight into how to handle future global changes. - Covers scientific, cultural, economic and political components of sea otter conservation - Provides guidance on how to manage threats to the sea otter populations in the face of future global changes - Highlights the effects that interactions of coastal animals have with the marine ecosystem

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.

  • Author : Kenneth A. Logan
  • Publisher : Island Press
  • Release : 2001-08-01
  • ISBN : 1610910583
  • Pages : 498 pages

Download or read book Desert Puma written by Kenneth A. Logan and published by Island Press. This book was released on 2001-08-01 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientists and conservationists are beginning to understand the importance of top carnivores to the health and integrity of fully functioning ecosystems. As burgeoning human populations continue to impinge on natural landscapes, the need for understanding carnivore populations and how we affect them is becoming increasingly acute.Desert Puma represents one of the most detailed assessments ever produced of the biology and ecology of a top carnivore. The husband-and-wife team of Kenneth Logan and Linda Sweanor set forth extensive data gathered from their ten-year field study of pumas in the Chihuahua Desert of New Mexico, also drawing on other reliable scientific data gathered throughout the puma's geographic range. Chapters examine: the evolutionary and modern history of pumas, their taxonomy, and physical description a detailed description and history of the study area in the Chihuahua Desert field techniques that were used in the research puma population dynamics and life history strategies the implications of puma behavior and social organization the relationships of pumas and their preyThe authors provide important new information about both the biology of pumas and their evolutionary ecology -- not only what pumas do, but why they do it. Logan and Sweanor explain how an understanding of puma evolutionary ecology can, and must, inform long-term conservation strategies. They end the book with their ideas regarding strategies for puma management and conservation, along with a consideration of the future of pumas and humans. Desert Puma makes a significant and original contribution to the science not only of pumas in desert ecosystems but of the role of top predators in all environments. It is an essential contribution to the bookshelf of any wildlife biologist or conservationist involved in large-scale land management or wildlife management.

Book excerpt: The loss and fragmentation of natural habitats is one of the major issues in wildlife management and conservation. Habitat "corridors" are sometimes proposed as an important element within a conservation strategy. Examples are given of corridors both as pathways and as habitats in their own right. Includes detailed reviews of principles relevant to the design and management of corridors, their place in regional approaches to conservation planning, and recommendations for research and management.

Book Valuing Chaparral

Download or read book Valuing Chaparral written by Emma C. Underwood and published by Springer. This book was released on 2018-04-09 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chaparral shrubland ecosystems are an iconic feature of the California landscape, and a highly biodiverse yet highly flammable backdrop to some of the fastest growing urban areas in the United States. Chaparral-type ecosystems are a common element of all of the world’s Mediterranean-type climate regions – of which California is one – yet there is little public appreciation of the intrinsic value and the ecosystem services that these landscapes provide. Valuing Chaparral is a compendium of contributions from experts in chaparral ecology and management, with a focus on the human relationship with chaparral ecosystems. Chapters cover a wide variety of subjects, ranging from biodiversity to ecosystem services like water provision, erosion control, carbon sequestration and recreation; from the history of human interactions with chaparral to current education and conservation efforts; and from chaparral restoration and management to scenarios of the future under changing climate, land use, and human population. Valuing Chaparral will be of interest to resource managers, the research community, policy makers, and the public who live and work in the chaparral dominated landscapes of California and other Mediterranean-type climate regions.

Book Cougar

    Book Details:
  • Author : Maurice Hornocker
  • Publisher : University of Chicago Press
  • Release : 2009-12-15
  • ISBN : 0226353478
  • Pages : 331 pages

Download or read book Cougar written by Maurice Hornocker and published by University of Chicago Press. This book was released on 2009-12-15 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cougar is one of the most beautiful, enigmatic, and majestic animals in the Americas. Eliciting reverence for its grace and independent nature, it also triggers fear when it comes into contact with people, pets, and livestock or competes for hunters’ game. Mystery, myth, and misunderstanding surround this remarkable creature. The cougar’s range once extended from northern Canada to the tip of South America, and from the Pacific to the Atlantic, making it the most widespread animal in the western hemisphere. But overhunting and loss of habitat vastly reduced cougar numbers by the early twentieth century across much of its historical range, and today the cougar faces numerous threats as burgeoning human development encroaches on its remaining habitat. When Maurice Hornocker began the first long-term study of cougars in the Idaho wilderness in 1964, little was known about this large cat. Its secretive nature and rarity in the landscape made it difficult to study. But his groundbreaking research yielded major insights and was the prelude to further research on this controversial species. The capstone to Hornocker’s long career studying big cats, Cougar is a powerful and practical resource for scientists, conservationists, and anyone with an interest in large carnivores. He and conservationist Sharon Negri bring together the diverse perspectives of twenty-two distinguished scientists to provide the fullest account of the cougar’s ecology, behavior, and genetics, its role as a top predator, and its conservation needs. This compilation of recent findings, stunning photographs, and firsthand accounts of field research unravels the mysteries of this magnificent animal and emphasizes its importance in healthy ecosystem processes and in our lives.

Book Landscape Ecology in Theory and Practice

Download or read book Landscape Ecology in Theory and Practice written by Monica G. Turner and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: An ideal text for students taking a course in landscape ecology. The book has been written by very well-known practitioners and pioneers in the new field of ecological analysis. Landscape ecology has emerged during the past two decades as a new and exciting level of ecological study. Environmental problems such as global climate change, land use change, habitat fragmentation and loss of biodiversity have required ecologists to expand their traditional spatial and temporal scales and the widespread availability of remote imagery, geographic information systems, and desk top computing has permitted the development of spatially explicit analyses. In this new text book this new field of landscape ecology is given the first fully integrated treatment suitable for the student. Throughout, the theoretical developments, modeling approaches and results, and empirical data are merged together, so as not to introduce barriers to the synthesis of the various approaches that constitute an effective ecological synthesis. The book also emphasizes selected topic areas in which landscape ecology has made the most contributions to our understanding of ecological processes, as well as identifying areas where its contributions have been limited. Each chapter features questions for discussion as well as recommended reading.

Book Human Wildlife Interactions

Download or read book Human Wildlife Interactions written by Michael R. Conover and published by CRC Press. This book was released on 2022-01-05 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book won the 2023 The Wildlife Society Publication Award in the authored book category. Human-wildlife interactions increase exponentially as more and more humans and wildlife crowd into the same limited space. Such interactions often become conflicts when wildlife threaten human health and safety, well-being, or the food supply. This second edition of Human-Wildlife Interactions: From Conflict to Coexistence provides a comprehensive review of the severity of these problems and the methods used to resolve clashes between humans and wildlife. During his forty-year career as a wildlife professor and scientist, Dr. Michael Conover, founder of journal Human-Wildlife Interactions, has become a recognized leader of the scientific field of human-wildlife interactions. In this book, he presents the range of methods for wildlife damage management, including employing lethal methods; distributing supplemental food; changing the behavior of either humans or wildlife; and excluding or repelling wildlife. Backed by numerous case studies and informative side bars, the book documents resolutions to specific human-wildlife conflicts throughout the literature. Containing full color illustrations throughout, the second edition of Human-Wildlife Interactions: From Conflict to Coexistence provides authoritative coverage and depth of both theoretical and practical information. It serves as an invaluable resource for students, researchers, and professional wildlife managers. Disclaimer: Figure 7.7 (b) on page 251 was incorrectly attributed in previous printings.

Book Urban Wildlife Conservation

Download or read book Urban Wildlife Conservation written by Robert A. McCleery and published by Springer. This book was released on 2014-11-11 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past, wildlife living in urban areas were ignored by wildlife professionals and urban planners because cities were perceived as places for people and not for wild animals. Paradoxically, though, many species of wildlife thrive in these built environments. Interactions between humans and wildlife are more frequent in urban areas than any other place on earth and these interactions impact human health, safety and welfare in both positive and negative ways. Although urban wildlife control pest species, pollinate plants and are fun to watch, they also damage property, spread disease and even attack people and pets. In urban areas, the combination of dense human populations, buildings, impermeable surfaces, introduced vegetation, and high concentrations of food, water and pollution alter wildlife populations and communities in ways unseen in more natural environments. For these ecological and practical reasons, researchers and mangers have shown a growing interest in urban wildlife ecology and management. This growing interest in urban wildlife has inspired many studies on the subject that have yet to be synthesized in a cohesive narrative. Urban Wildlife: Theory and Practice fills this void by synthesizing the latest ecological and social knowledge in the subject area into an interdisciplinary and practical text. This volume provides a foundation for the future growth and understanding of urban wildlife ecology and management by: • Clearly defining th e concepts used to study and describe urban wildlife, • Offering a cohesive understanding of the coupled natural and social drivers that shape urban wildlife ecology, • Presenting the patterns and processes of wildlife response to an urbanizing world and explaining the mechanisms behind them and • Proposing means to create physical and social environments that are mutually beneficial for both humans and wildlife.
