This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Vancouver Island marmot (Marmota vancouverensis) is an endangered mammal whose population is being recovered with a conservation breeding and release program. This involves management both in and ex situ, so it is vital to understand how the different environments are affecting the populations to maximize program outcomes. The purpose of this thesis was to retrospectively analyze data collected from this program to address questions relevant to population recovery. The first chapter compared the physiology of the managed populations using the neutrophil: lymphocyte ratio and found significant differences in this metric among targeted comparisons. The second chapter assessed factors that may be contributing to hibernation-related mortality of marmots during their first winter post-release. I found a combination of environmental and intrinsic factors influencing this mortality. Overall, this thesis contributes to a growing body of literature surrounding the efficacy of conservation breeding and release programs to recover critically endangered species.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Vancouver Island Marmot (Marmota vancouverensis) is an endangered rodent endemic to the mountains of Vancouver Island, British Columbia, Canada. Following population declines in the 1980s and 1990s, an intensive captive breeding and reintroduction program was initiated involving three Canadian zoos and a purpose-built, subalpine facility on Vancouver Island. From 1997 to 2017, 660 marmots were associated with the captive program, including 63 wild-born individuals captured for breeding and 597 marmots born and weaned in captivity. Reintroductions began in 2003 and by 2017 a total of 501 marmots had been released. Although this significantly increased the wild population from its low point in 2003, conservation of the Vancouver Island Marmot (VIM) continues to involve intensive ex situ management, reintroductions, and translocations. Health and disease surveillence is fundamental to the success of conservation programs like the marmot recovery project. This thesis builds upon our understanding of VIM health by describing and evaluating select health parameters, to determine baseline characteristics for VIM under its different treatments (wild, captive and captive-release) and to identify potential risk factors that may influence the health of the marmot's population and its capacity to achieve recovery objectives. The analysis involved data that was collected between 1992 and 2016, and included 1,106 VIM blood profiles, 3,174 physical examinations, 140 post mortem examinations and 533 field mortality records. VIM hematology and serum biochemistry reference ranges were calculated as a baseline metric and were qualitatively comparable to published values for other rodent species. Leukogram and protein values were found to have potential utility as a quantitative measure for comparing VIM management groups. There were significant differences in the clinical and pathological data collected from captive and free-ranging (captive-release and wild) marmots. Captives could be monitored with greater intensity and to an older age, due to increased longevity. A host of clinical and pathological disorders were described in captive marmots, including age-related, management-related, and congenital problems. There was a paucity of health conditions identified in free-ranging VIM and this could be due to a fundamental lack of disease, or limited opportunities to conduct post mortem examinations or evaluate compromised individuals in the field. The analysis did not identify any specific infectious agents that represented a generalized population threat to VIM. Cardiomyopathy and neoplasia, which occurred in older individuals, were the most consequential health complications for captive marmots. Implantation of abdominal radio-transmitters was not found to impact marmot health and was important for identifying mortalities in the field. The first wild hibernation represented a time of significant mortality for VIM released from captivity. However, reintroduced marmots that survived their first year in the wild were comparable to their wild-born counterparts with respect to hibernation success and clinical presentation. Predators continued to represent a major cause of mortality for free-ranging marmots. In the absence of other identified health threats, predation and reduced hibernation success of captive-release marmots appear to be significant factors limiting the health and potential recovery of the in situ population.

Available in PDF, EPUB and Kindle. Book excerpt: Since 1985, faunal remains of the Vancouver Island marmot (Marmota vancouverensis) have been discovered in four high-elevation cave sites, two in Strathcona Provincial Park and a third in Clayoquot Plateau Provincial Park. Cut marks on bones and artefacts recovered at one site indicate that the remains are the result of human hunting, and radiocarbon dating has revealed the prehistoric ages of the sites. No marmots live in the vicinity of the cave sites today, and the remains provide additional evidence for a range decline in the marmot. This report summarises the analysis of faunal remains (not only of marmot but also of other mammals) and reviews the implications for Vancouver Island marmot biogeography and conservation, as well as for Aboriginal cultural history. Recommendations are also presented for future research in British Columbia parks and for managing those cave sites.

Available in PDF, EPUB and Kindle. Book excerpt: This book began life as a review article. That article spawned a symposium which was, in turn, greatly expanded to form the present volume. As the project moved through these developmental stages (hopefully, towards attainment of its full maturity), a number of people have provided invaluable assistance to us, and we would like to take this opportunity to thank them. Gordon Orians must certainly take a high place in that list. He has been both a friend and mentor to W.E.K., and many of the topics explored in this book have emerged from the resultant dialogue. His thought processes, ideas and perhaps even some of his turns of phrase emerge throughout much ofthe book. Gordon also played a pivotal role in inviting in motion, and so he has served as a catalyst the article that set this project to the book as well as one of its reagents. While he has not served as an editor of this book, he is one of its authors in more than just the literal sense.

Book excerpt: The problems related to the process of industrialisation such as biodiversity depletion, climate change and a worsening of health and living conditions, especially but not only in developing countries, intensify. Therefore, there is an increasing need to search for integrated solutions to make development more sustainable. The United Nations has acknowledged the problem and approved the “2030 Agenda for Sustainable Development”. On 1st January 2016, the 17 Sustainable Development Goals (SDGs) of the Agenda officially came into force. These goals cover the three dimensions of sustainable development: economic growth, social inclusion and environmental protection. The Encyclopedia of the UN Sustainable Development Goals comprehensively addresses the SDGs in an integrated way. It encompasses 17 volumes, each one devoted to one of the 17 SDGs. This volume addresses SDG 15, namely "Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss" and contains the description of a range of terms, which allow a better understanding and foster knowledge. Concretely, the defined targets are: Ensure the conservation, restoration and sustainable use of terrestrial and inland freshwater ecosystems and their services, in particular forests, wetlands, mountains and drylands, in line with obligations under international agreements Promote the implementation of sustainable management of all types of forests, halt deforestation, restore degraded forests and substantially increase afforestation and reforestation globally Combat desertification, restore degraded land and soil, including land affected by desertification, drought and floods, and strive to achieve a land degradation-neutral world Ensure the conservation of mountain ecosystems, including their biodiversity, in order to enhance their capacity to provide benefits that are essential for sustainable development Take urgent and significant action to reduce the degradation of natural habitats, halt the loss of biodiversity and protect and prevent the extinction of threatened species Promote fair and equitable sharing of the benefits arising from the utilization of genetic resources and promote appropriate access to such resources, as internationally agreed Take urgent action to end poaching and trafficking of protected species of flora and fauna and address both demand and supply of illegal wildlife products Introduce measures to prevent the introduction and significantly Reduce the impact of invasive alien species on land and water ecosystems and control or eradicate the priority species Integrate ecosystem and biodiversity values into national and local planning, development processes, poverty reduction strategies and accounts Mobilize and significantly increase financial resources from all sources to conserve and sustainably use biodiversity and ecosystems Mobilize significant resources from all sources and at all levels to finance sustainable forest management and provide adequate incentives to developing countries to advance such management, including for conservation and reforestation Enhance global support for efforts to combat poaching and trafficking of protected species, including by increasing the capacity of local communities to pursue sustainable livelihood opportunities Editorial Board Alexandra Aragão, Desalegn Yayeh Ayal, Ayansina Ayanlade, Anabela Marisa Azul, Adriana Consorte-McCrea, Muhammad Farooq, Ana Catarina Luz, María P.
