Available in PDF, EPUB and Kindle. Book excerpt: "The summer range of the Teshekpuk Caribou (Rangifer tarandus granti) Herd is currently undergoing the initial stages of petroleum exploration and development. Pre-development baseline information is necessary to interpret post-development distribution and habitat selection of caribou and to develop mitigation measures. We estimated bi-weekly distributions, diet and habitat selection by caribou during the summers, 2002-2004, based on aerial relocations of 21-49 radio-collared females. Little or no habitat selection was detected when comparing used locations to habitat available within bi-weekly utilization distributions. Habitat selection was much stronger when comparing bi-weekly utilization distributions to the remaining area of summer use. At the latter scale of analysis, there were dynamic temporal patterns in resource selection by caribou. High air temperature was strongly avoided throughout July. Tussock tundra was avoided early in the summer, but selected during August. Wet sedge was selected in June and from late-August through September. Estimates of dietary nitrogen content indicated that high nitrogen concentrations are available only for a short period in early summer, and declined well before forage biomass. Predicted dietary nitrogen concentration appeared to be much lower for the Teshekpuk Caribou Herd than for the Porcupine Caribou Herd. Successful mitigation measures for petroleum development in NPR-A will need to be spatially and temporally tailored to observed dynamic patterns in caribou resource selection. Future work should estimate the performance of caribou (e.g., survival or weight gain) in relation to habitat quality and use in order to confirm the value of selected habitats and to enhance the robustness of mitigation measures"--Leaf iii.

Available in PDF, EPUB and Kindle. Book excerpt: Report of a study (1979-1987) on the range ecology of the Porcupine Caribou Herd of Grant's caribou (Rangifer tarandus-granti)that migrates annually from summer range on the arctic coastal plain of Alaska and Yukon to winter in the forested valleys and plains of north-central Yukon and western Alaska. The study was undertaken by the Yukon Dept. of Renewable Resources and the Canadian Wildlife Service because of concern about proposed developments within the range of the caribou.

Download or read book Population Structure and Hybridization of Alaskan Caribou and Reindeer written by Karen H. Mager and published by . This book was released on 2012 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alaskan caribou (Rangifer tarandus granti) are a valued game species and a key grazer in Alaska's terrestrial ecosystem. Caribou herds, defined by female fidelity to calving grounds, are management units. However, the extent to which herds constitute genetic populations is unknown. Historical fluctuations in herd size, range, and distribution suggest periods of contact and isolation between herds. Likewise, historical contact between caribou and introduced domestic reindeer (R.t. tarandus) created opportunities for hybridization, but its extent is not known. I conducted an interdisciplinary study to understand how historical processes influence genetic identity and population structure of caribou and reindeer. Interviews with herders and hunters in Barrow, Alaska, revealed that many reindeer migrated away with caribou in the 1940s despite herder efforts to prevent mixing. Local observations of reindeer-like animals in caribou herds today suggest feral reindeer may survive and interbreed. Using genetic analysis of North Slope caribou and Seward Peninsula reindeer (n = 312) at 19 microsatellite loci, I detected individuals with hybrid ancestry in all four caribou herds and in reindeer. Selective hunting of reindeer-like animals, along with herd size and natural selection, may remove reindeer from caribou herds over time. I used genetics as well to describe caribou population structure and determine how it is influenced by geography, historical demography, and ecotypes. I found that Alaskan caribou from 20 herds (n = 655) are subdivided into two genetic clusters: the Alaska Peninsula and the mainland. Alaska Peninsula herds are genetically distinct, while many mainland herds are not. I hypothesize that Alaska Peninsula herds have diverged due to post-glacial founder effects and recent bottlenecks driven by constraints to population size from marginal habitat and reduced gene flow across a habitat barrier at the nexus of the peninsula. I hypothesize that mainland herds have maintained genetic connectivity and large effective population size via range expansions and shifts over time. However, I find evidence that herds of different ecotypes (migratory, sedentary) can remain differentiated despite range overlap. Genetic evidence provides information for herd-based management, while also demonstrating the importance of spatial connectivity of herds and their habitats over the long-term.

Download or read book Reindeer and Caribou written by Morten Tryland and published by CRC Press. This book was released on 2018-11-09 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive presentation of health and diseases in reindeer and caribou, or just Rangifer, a key Circumarctic species with broad social and ecological value. It is an essential reference for anyone interested in the biology and health of wild or semi-domesticated reindeer and caribou, and is more broadly relevant for those with interests in other species of free-ranging and captive cervids. Beginning with a general introduction to Rangifer as a species, it then focuses on Rangifer "health" as a concept and describes the determinants of health at an individual and population level. Chapters cover a range of topics from nutrition and feeding to stress, non-infectious and infectious diseases, meat hygiene, capture and restraint, diagnosis and treatment of health issues, and finally, potential impacts of climate change on health of Rangifer. Reindeer and Caribou: Health and Disease compiles extensive research and experience-based information on issues ranging from drug doses for chemical immobilization, blood chemistry values, and raising an orphaned calf. In addition, it contains hundreds of high quality colour illustrations that contribute to its value as a diagnostic resource for recognizing various parasites, pathogens and signs of disease, both in live and dead animals. Each chapter is followed by a comprehensive list of references and a list of contact information for all the contributors, identifying world experts in the different areas of health for this circumpolar and fascinating species. This book is compulsory reading and an indispensable resource for anyone dealing with health in reindeer and caribou, including veterinarians, wildlife biologists and managers, reindeer herders/game ranchers, zoological husbandry personnel, and students with wildlife health.

This book was released on 2012-09-15 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In his final, major publication Ernest S. “Tiger” Burch Jr. reconstructs the distribution of caribou herds in northwest Alaska using data and information from research conducted over the past several decades as well as sources that predate western science by more than one hundred years. Additionally, he explores human and natural factors that contributed to the demise and recovery of caribou and reindeer populations during this time. Burch provides an exhaustive list of published and unpublished literature and interviews that will intrigue laymen and experts alike. The unflinching assessment of the roles that humans and wolves played in the dynamics of caribou and reindeer herds will undoubtedly strike a nerve. Supplemental essays before and after the unfinished work add context about the author, the project of the book, and the importance of both.

Available in PDF, EPUB and Kindle. Book excerpt: A companion volume to Environmental Conflict in Alaska, Pioneering Conservation in Alaska chronicles the central land and wildlife issues and the growth of environmental conservation in Alaska during its Russian and territorial eras. The Alaskan frontier tempted fur traders, whalers, salmon fishers, gold miners, hunters, and oilmen to take what they could without regard for long-term consequences. Wildlife species, ecosystems, and Native cultures suffered, sometimes irreparably. Damage to wildlife and lands drew the attention of environmentalists, including John Muir, who applied their influence to enact wildlife protection laws and set aside lands for conservation. Alaska served as a testing ground for emergent national resource policy in the United States, as environmental values of species and ecosystem sustainability replaced the unrestrained exploitation of Alaska's early frontier days. Efforts of conservation leaders and the territory's isolation, small human population, and late development prevented widespread destruction and gave Americans a unique opportunity to protect some of the world's most pristine wilderness. Enhanced by more than 100 photographs, Pioneering Conservation in Alaska illustrates the historical precedents for current natural resource disputes in Alaska and will fascinate readers interested in wildlife and conservation.
