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.

Book Synopsis Occupancy Estimation and Modeling by : Darryl I. MacKenzie
Download or read book Occupancy Estimation and Modeling written by Darryl I. MacKenzie and published by Elsevier. This book was released on 2017-11-17 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: Occupancy Estimation and Modeling: Inferring Patterns and Dynamics of Species Occurrence, Second Edition, provides a synthesis of model-based approaches for analyzing presence-absence data, allowing for imperfect detection. Beginning from the relatively simple case of estimating the proportion of area or sampling units occupied at the time of surveying, the authors describe a wide variety of extensions that have been developed since the early 2000s. This provides an improved insight about species and community ecology, including, detection heterogeneity; correlated detections; spatial autocorrelation; multiple states or classes of occupancy; changes in occupancy over time; species co-occurrence; community-level modeling, and more. Occupancy Estimation and Modeling: Inferring Patterns and Dynamics of Species Occurrence, Second Edition has been greatly expanded and detail is provided regarding the estimation methods and examples of their application are given. Important study design recommendations are also covered to give a well rounded view of modeling. - Provides authoritative insights into the latest in occupancy modeling - Examines the latest methods in analyzing detection/no detection data surveys - Addresses critical issues of imperfect detectability and its effects on species occurrence estimation - Discusses important study design considerations such as defining sample units, sample size determination and optimal effort allocation
Book Synopsis Vancouver Island Marmot Bones from Subalpine Caves by : David W. Nagorsen
Download or read book Vancouver Island Marmot Bones from Subalpine Caves written by David W. Nagorsen and published by . This book was released on 1996 with total page 80 pages. 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.
