Book excerpt: Urbanization is a process widely recognized for affecting the distribution and abundance of wildlife. Urbanization represents a syndrome of changes to the biophysical environment associated with increasing human population density; however, in ecological studies, urbanization is often treated as a qualitative, dichotomous landcover state (e.g., urban v. rural) or represented by a single covariate (e.g., area of impervious surface). This is potentially problematic when studying wildlife in urbanizing landscapes because wildlife will respond to the suite of specific changes to the biophysical environment that accompany increased human density. The objectives of my thesis were to analyze changes in habitat attributes in relation to human population density within the Santa Monica Mountains National Recreation Area and to relate patterns of amphibian and reptile distributions to specific environmental attributes or principal components of urbanizing habitats. I use four years of capture data from 79 pitfall arrays. Among our study sites, human population density was negatively correlated with protected area patch size, proximity to paved surfaces, human-made structures and artificial light sources. Models of reptile and amphibian occupancy and abundance generally did not include consistent urban attributes nor the composite index of urban attributes. For the most common lizard species, Western fence lizards (Sceloporus occidentalis) occupancy was positively correlated with human population density and slender salamander (Batrachoseps spp.) occupancy increased within greater proximity to human-made water sources. Occupancy of all other less common reptile species was related to vegetation and/or elevation, not directly related to the anthropogenic impacts of urbanization. Abundance model fit was generally poor; however, results suggest that abundance varied with vegetation among most herpetofaunal species. Our survival models generated similar results for Western fence lizards under count-based modeling approaches; however, both the count-based and capture-mark-recapture approaches may have generated inflated estimates due to low recapture rates and sampling design constraints.

Book Synopsis Modeling Suitable Habitat Under Climate Change for Chaparral Shrub Communities in the Santa Monica Mountains National Recreation Area, California by : Jennifer James
Download or read book Modeling Suitable Habitat Under Climate Change for Chaparral Shrub Communities in the Santa Monica Mountains National Recreation Area, California written by Jennifer James and published by . This book was released on 2014 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Species distribution modeling is used to study changes in biodiversity and species range shifts, two currently well-known manifestations of climate change. The focus of this study is to explore how distributions of suitable habitat might shift under climate change for shrub communities within the Santa Monica Mountains National Recreation Area (SMMNRA), through a comparison of community level to individual species level distribution modeling. Species level modeling is more commonly utilized, in part because community level modeling requires detailed community composition data that are not always available. However, community level modeling may better detect patterns in biodiversity. To examine the projected impact on suitable habitat in the study area, I used the MaxEnt modeling algorithm to create and evaluate species distribution models with presence only data for two future climate models at community and individual species levels. I contrasted the outcomes as a method to describe uncertainty in projected models. To derive a range of sensitivity outcomes I extracted probability frequency distributions for suitable habitat from raster grids for communities modeled directly as species groups and contrasted those with communities assembled from intersected individual species models. The intersected species models were more sensitive to climate change relative to the grouped community models. Suitable habitat in SMMNRA's bounds was projected to decline from about 30-90% for the intersected models and about 20-80% for the grouped models from its current state. Models generally captured floristic distinction between community types as drought tolerance. Overall the impact on drought tolerant communities, growing in hotter, drier habitat such as Coastal Sage Scrub, was predicted to be less than on communities growing in cooler, moister more interior habitat, such as some chaparral types. Of the two future climate change models, the wetter model projected less impact for most communities. These results help define risk exposure for communities and species in this conservation area and could be used by managers to focus vegetation monitoring tasks to detect early response to climate change. Increasingly hot and dry conditions could motivate opportunistic restoration projects for Coastal Sage Scrub, a threatened vegetation type in Southern California.
Book Synopsis Urban Wildlife Management, Second Edition by : Clark E. Adams
Download or read book Urban Wildlife Management, Second Edition written by Clark E. Adams and published by CRC Press. This book was released on 2012-06-15 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the first edition of Urban Wildlife Management was published two years ago, it provided conservationists, ecologists, and wildlife professionals with a welcome shift in the way that interactions between humans and wildlife were viewed and managed. Instead of focusing on ways to evict or eradicate wildlife encroached on by urban development, this unique work took a holistic, ecosystems approach. Gathering information from more than five hundred academic sources and the popular media, this book educated us on the complete nature of the problem. See what's new in the Second Edition: New information garnered from secondary data sets Added contributions from an extended list of leading wildlife specialists Original research conducted by the authors and their students New chapters on urban soils, urban waters, and zoonotic diseases More perspective essays and case studies Single species profiles in each chapter that focus on management issues Numerous tables examining trends by species and by region Through discussions of past and present approaches in the United States, the book explores the changing landscape of wildlife management and future approaches. Urban habitats and hazards are defined in terms of green and gray spaces. Sociopolitical issues are discussed in terms of wildlife management, stakeholder responsibilities, and legal considerations. And wildlife are viewed as adaptive inhabitants of an evolving ecosystem rather than as interlopers in a humans only world. The author maintains a blog exploring wildlife in our own backyard.
Book Synopsis Landscape Ecology in Theory and Practice by : Monica G. Turner
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 Synopsis Mangrove Ecosystems: A Global Biogeographic Perspective by : Victor H. Rivera-Monroy
Download or read book Mangrove Ecosystems: A Global Biogeographic Perspective written by Victor H. Rivera-Monroy and published by Springer. This book was released on 2017-11-03 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive overview and analysis of mangrove ecological processes, structure, and function at the local, biogeographic, and global scales and how these properties interact to provide key ecosystem services to society. The analysis is based on an international collaborative effort that focuses on regions and countries holding the largest mangrove resources and encompasses the major biogeographic and socio-economic settings of mangrove distribution. Given the economic and ecological importance of mangrove wetlands at the global scale, the chapters aim to integrate ecological and socio-economic perspectives on mangrove function and management using a system-level hierarchical analysis framework. The book explores the nexus between mangrove ecology and the capacity for ecosystem services, with an emphasis on thresholds, multiple stressors, and local conditions that determine this capacity. The interdisciplinary approach and illustrative study cases included in the book will provide valuable resources in data, information, and knowledge about the current status of one of the most productive coastal ecosystem in the world.
Book Synopsis Ecology of Fragmented Landscapes by : Sharon K. Collinge
Download or read book Ecology of Fragmented Landscapes written by Sharon K. Collinge and published by JHU Press. This book was released on 2009-06 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ask airline passengers what they see as they gaze out the window, and they will describe a fragmented landscape: a patchwork of desert, woodlands, farmlands, and developed neighborhoods. Once-contiguous forests are now subdivided; tallgrass prairies that extended for thousands of miles are now crisscrossed by highways and byways. Whether the result of naturally occurring environmental changes or the product of seemingly unchecked human development, fractured lands significantly impact the planet’s biological diversity. In Ecology of Fragmented Landscapes, Sharon K. Collinge defines fragmentation, explains its various causes, and suggests ways that we can put our lands back together. Researchers have been studying the ecological effects of dismantling nature for decades. In this book, Collinge evaluates this body of research, expertly synthesizing all that is known about the ecology of fragmented landscapes. Expanding on the traditional coverage of this topic, Collinge also discusses disease ecology, restoration, conservation, and planning. Not since Richard T. T. Forman's classic Land Mosaics has there been a more comprehensive examination of landscape fragmentation. Ecology of Fragmented Landscapes is critical reading for ecologists, conservation biologists, and students alike.
Book Synopsis Effects of Anthropogenic Noise on Animals by : Hans Slabbekoorn
Download or read book Effects of Anthropogenic Noise on Animals written by Hans Slabbekoorn and published by Springer. This book was released on 2018-08-20 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past several years, many investigators interested in the effects of man-made sounds on animals have come to realize that there is much to gain from studying the broader literature on hearing sound and the effects of sound as well as data from the effects on humans. It has also become clear that knowledge of the effects of sound on one group of animals (e.g., birds or frogs) can guide studies on other groups (e.g., marine mammals or fishes) and that a review of all such studies together would be very useful to get a better understanding of the general principles and underlying cochlear and cognitive mechanisms that explain damage, disturbance, and deterrence across taxa. The purpose of this volume, then, is to provide a comprehensive review of the effects of man-made sounds on animals, with the goal of fulfilling two major needs. First, it was thought to be important to bring together data on sound and bioacoustics that have implications across all taxa (including humans) so that such information is generally available to the community of scholars interested in the effects of sound. This is done in Chaps. 2-5. Second, in Chaps. 6-10, the volume brings together what is known about the effects of sound on diverse vertebrate taxa so that investigators with interests in specific groups can learn from the data and experimental approaches from other species. Put another way, having an overview of the similarities and discrepancies among various animal groups and insight into the “how and why” will benefit the overall conceptual understanding, applications in society, and all future research.
Download or read book Biodiversity written by N. Biedinger and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodiversity, sometimes simply understood as "diversity of species", is a specific quality of life on our planet, the dimensions and importance of which have just lately been fully realized. Today we know that "biological diversity is a global asset of incalculable value to present and future generations" (Kofi Annan). Biodiversity is spread unequally over the world: in fact, the main share of biological resources worldwide is harboured predominantly by the so-called developing countries in the tropics and sub tropics. Therefore, Biodiversity - A Challenge for Development Research and Policy was chosen as the title for an international conference which was held in Bonn in 1997 as one of the first major events organized by the then newly established North-South Centre for Development Research (ZEF) at Rheinische Friedrich-Wilhelms-Universitat Bonn (Germany). Since the ZEF, founded by the Senate of the University of Bonn in 1995, has played a central role in turning Bonn into a centre for international cooperation and North-South dialogue. The Centre is a product of the Bonn Berlin agreement of July 1994 which was adopted to offset the effects caused by the Parliament and much of the Government moving to Berlin. It fits in well with the double strategy to strengthen Bonn's position as an interna tional science arena and as an eminent place for development policy and the national and supranational agencies dealing with this issue.
Book Synopsis The Influence of Global Environmental Change on Infectious Disease Dynamics by : Institute of Medicine
Download or read book The Influence of Global Environmental Change on Infectious Disease Dynamics written by Institute of Medicine and published by National Academies Press. This book was released on 2014-09-03 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: The twentieth century witnessed an era of unprecedented, large-scale, anthropogenic changes to the natural environment. Understanding how environmental factors directly and indirectly affect the emergence and spread of infectious disease has assumed global importance for life on this planet. While the causal links between environmental change and disease emergence are complex, progress in understanding these links, as well as how their impacts may vary across space and time, will require transdisciplinary, transnational, collaborative research. This research may draw upon the expertise, tools, and approaches from a variety of disciplines. Such research may inform improvements in global readiness and capacity for surveillance, detection, and response to emerging microbial threats to plant, animal, and human health. The Influence of Global Environmental Change on Infectious Disease Dynamics is the summary of a workshop hosted by the Institute of Medicine Forum on Microbial Threats in September 2013 to explore the scientific and policy implications of the impacts of global environmental change on infectious disease emergence, establishment, and spread. This report examines the observed and potential influence of environmental factors, acting both individually and in synergy, on infectious disease dynamics. The report considers a range of approaches to improve global readiness and capacity for surveillance, detection, and response to emerging microbial threats to plant, animal, and human health in the face of ongoing global environmental change.
