Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the use of molecular tools to study small populations of rare and endangered mammals, and presents case studies that apply an evolutionary framework to address innovative questions in the emerging field of mammalian conservation genomics using a highly diverse set of novel molecular tools. Novel and more precise molecular technologies now allow experts in the field of mammology to interpret data in a more contextual and empirical fashion and to better describe the evolutionary and ecological processes that are responsible for the patterns they observe. The book also demonstrates how recent advances in genetic/genomic technologies have been applied to assess the impact of environmental/anthropogenic changes on the health of small populations of mammals. It examines a range of issues in the field of mammalian conservation genomics, such as the role that the genetic diversity of the immune system plays in disease protection and local adaptation; the use of noninvasive techniques and genomic banks as a resource for monitoring and restoring populations; the structuring of population by physical barriers; and genetic diversity. Further, by integrating research from a variety of areas – including population genetics, molecular ecology, systematics, and evolutionary and conservation biology – it enables readers to gain a deeper understanding of the conservation biology of mammals that are at increasing risk of extinction at local, regional and global scales. As such, it offers a unique resource for a broad readership interested in the conservation biology of mammals and conservation management strategies to better preserve biodiversity.
Download or read book The Biology and Conservation of Wild Canids written by David W. Macdonald and published by OUP Oxford. This book was released on 2004-06-24 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: No group of wild mammals so universally captures the emotions of people world-wide than do wild canids. That emotion can be enchantment and fascination, but it can also be loathing, because the opportunism that is the hallmark of the dog family also leads them into conflict with humans. In the developed world at least, the fascination with wild canids doubtless stems from people's captivation with domestic dogs - everybody feels they are an expert on canids! While most people may be familiar with only the better known members of the dog family, such as the grey wolf and the red fox, there are in fact 36 species of wolves, dogs, jackals and foxes. They attract hugely disproportionate interest from academics, conservationists, veterinarians, wildlife managers and the general public. This book brings together in single volume an astonishing synthesis of research done in the last twenty years and is the first truly compendious synthesis on wild canids. Beginning with a complete account of all 36 canid species, there follow six review chapters that emphasise topics most relevant to canid conservation science, including evolution and systematics, behavioural ecology, population genetics, diseases, conflict/control of troublesome species, and conservation tools. Fifteen detailed case studies then delve deeply into the very best species investigations currently available written by all the leading figures in the field. Much of the material is previously unpublished and will make fascinating reading far beyond the confines of canid specialists. These chapters portray the unique attributes of wild canids, their fascinating (and conflictive) relationship with man, and suggestions for future research and conservation measures for the Canidae. While most canid species are widespread and thrive in human dominated landscapes, several are in severe jeopardy; habitat loss, illegal hunting, persecution by farmers and disease all imperil dwindling populations. A final chapter analyses the requirements of, and approaches to, practical conservation, with lessons that go far beyond the dog family. It concentrates particular attention on priorities for the protection of the most threatened canid species, including the red wolf, African wild dog, Ethiopian wolf, Island fox and Darwin's fox. The wild canids provide examples that will thrill the evolutionary biologists and theoretician, enthral the natural historian and challenge the conservationist and wildlife manager. Anybody interested in evolutionary and behavioural biology, in mammals, in the environment, or in conservation will find much that is new and enriching in this book.

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.
Download or read book Rewilding Agricultural Landscapes written by H. Scott Butterfield and published by Island Press. This book was released on 2021-04-08 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the world population grows, so does the demand for food, putting unprecedented pressure on agricultural lands. In many desert dryland regions, however, intensive cultivation is causing their productivity to decline precipitously. "Rewilding" the least productive of these landscapes offers a sensible way to reverse the damage, recover natural diversity, and ensure long-term sustainability of remaining farms and the communities they support. This accessibly written, groundbreaking contributed volume is the first to examine in detail what it would take to retire eligible farmland and restore functioning natural ecosystems. The lessons in Rewilding Agricultural Landscapes will be useful to conservation leaders, policymakers, groundwater agencies, and water managers looking for inspiration and practical advice for solving the complicated issues of agricultural sustainability and water management.

Download or read book A New Niche for the Itch written by Jaime Leanne Rudd and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The San Joaquin kit fox (Vulpes macrotis mutica) is the only subspecies of kit fox endemic to California and is federally endangered. Although this small fox exhibits incredible adaptability, its geographic distribution is limited and contracting due to profound habitat destruction. Only twelve populations persist, including a unique urbanized satellite population which, until recently, thrived in the city of Bakersfield. This urban population had been considered a potential source population for reintroductions into remaining natural lands in the event of catastrophic kit fox population declines. In spring 2013, sarcoptic mange was first detected in the Bakersfield population. Preliminary data demonstrate that most or all infested kit foxes die if not treated, and therefore individual-based citywide treatment and rehabilitation are underway. Yet this individual-based approach to sarcoptic mange treatment has done little to slow the progression of disease through the population and there have been over 460 documented cases as of October 2018, demonstrating a need for a population-level intervention strategy. Therefore, the objectives of my dissertation were to: 1) determine whether sarcoptic mange in kit foxes and other sympatric canids is due to a shared vs. multiple diverse mite strains, 2) evaluate the effectiveness of a long-lasting acaricidal collar that might be used for a population-level intervention, and 3) identify additional health problems associated with mange to optimize medical management of mange-infested individuals in rehabilitation. The overarching goal was to conduct applied conservation research to inform future disease mitigation efforts. In Chapter 1, I used microsatellite genotypes of 351 Sarcoptes mites collected from kit foxes, red foxes (Vulpes vulpes), domestic dogs (Canis lupus familiaris), and coyotes (Canis latrans) to determine whether a kit fox variant of Sarcoptes scabiei mite was circulating only among kit foxes or if it was shared with these other sympatric canids. Bakersfield mites from kit foxes and red foxes showed the least loci polymorphism compared to coyotes and domestic dogs from the same area. The closest genetic relationship was between Bakersfield kit fox mites and Bakersfield red fox mites (FST = 0.060). In contrast, Bakersfield kit fox mites and Bakersfield coyote mites (FST = 0.509), and Bakersfield kit fox mites and Bakersfield dog mites (FST = 0.742) were much less closely related genetically. Further, only a single private allele (frequency of 0.005) was detected in kit fox mites; otherwise they shared alleles with coyotes and domestic dogs. These results demonstrate that the Sarcoptes mites are relatively host-specific and, although a spill-over event occurred initially, the primary route of mite transmission appears to be fox-to-fox. Therefore, future planning for a citywide intervention should focus on treating kit foxes. Accordingly, in Chapter 2, I evaluated a pilot intervention strategy that could reduce mite-infestation risk by deploying long-acting acaricidal collars on at-risk kit foxes. Traditional Sarcoptes treatments last anywhere from 10 days (ivermectin) to 28 days (selamectin), but S. scabiei infested individuals can live for up to 100 days before death and remain infectious during that time. The short duration of protection from standard treatment is not a feasible means to achieve herd immunity because individuals would need to be captured and treated every month. Flumethrin collars reportedly prevent sarcoptic mange infestation for up to 8 months, which make this an appealing alternative, but there was a need to test the claims of long-term protection and the true efficacy at the population level in reducing disease risk before a citywide intervention could be planned. Therefore, I performed a 2-year field trial with 35 kit foxes to study flumethrin’s safety, longevity, and efficaciousness. All kit foxes were treated with a single dose of selamectin (6mg/kg) and then assigned to the flumethrin treatment group (n = 17) and to the control group (n = 18). A Cox Proportional Hazards model was used to compare the duration of time it took for an individual to develop mange in the treated and control groups. There was no overall significant difference in the number of days before a kit fox in the treatment group developed mange (176 days) compared to the control group (171 days). Further, most mange transmission was observed within social groups, which could have serious consequences for mange transmission and spread if the entire family group is not synchronously treated. Like numerous drugs available on the market, flumethrin showed promise as being safe, long-lasting, and efficacious. However, its extra-label use in the field was not as effective as it is for treatment of mange in domestic animals. Finally, to better understand this debilitating, multisystemic disease process, in Chapter 3, I analyzed serum biochemistry and hematology values of kit foxes with mange and compared them to healthy kit foxes. Several serum chemistry and CBC parameters in mange-infested foxes were consistent with chronic disease and inflammation, starvation, and dehydration – a similar pathogenesis that has been observed in other canids and bobcats (Lynx rufus). The alterations in blood values observed indicate that kit foxes must be properly hydrated and their protein requirement supported while antibiotics and antiparasitic medications are administered in order to improve their chance of survival in rehabilitation. This dissertation focused on various aspects of a recent sarcoptic mange outbreak in San Joaquin kit foxes living in an urban city in California. Using molecular epidemiology, I was able to show that the current transmission dynamics of sarcoptic mange and thus intervention efforts should focus on kit foxes. While flumethrin was safe, its extra-label use in the field was not as efficacious for the treatment and prevention of sarcoptic mange as it is for domestic animals. Further, these results identified various health parameters that should be addressed for mange-infested kit foxes presented for rehabilitation to increase their chances of survival during treatment. Additional studies focusing on mange transmission, novel medications, and kit fox sociology should be conducted to determine what refinements could improve individual animal protection and reduce the impacts of this disease in kit foxes.
