Available in PDF, EPUB and Kindle. Book excerpt: "Barren-ground caribou (Rangifer tarandus granti) exhibit relative fidelity to calving grounds each spring. The Western Arctic Herd (WAH) and Teshekpuk Lake Herd (TLH) calve separately on Alaska's north slope, each selective of the dominant vegetation type. The WAH consumed mostly sedges, though the TLH diet varied. Despite differing snow conditions between the calving grounds, both herds were selective of the lowest snow cover class. Rugged terrain was avoided by both herds. While the TLH selected a high rate of increase in biomass, the WAH selected high biomass at calving and at peak lactation. Climate trends (1985-2001) were variable. There was a warming trend on the WAH calving ground, though no significant trends were present on the TLH calving ground, as expressed by median NDVI on 21 June. These herds have similar winter ranges and population trends, yet they differ in respect to habitat composition, selection and climate patterns during calving"--Leave iv.

Download or read book Daily Heterogeneity in Habitat Selection by the Porcupine Caribou Herd During Calving written by Rachel Rands Jones and published by . This book was released on 2005 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Caribou exhibit scale-dependent habitat selection, but variance in daily habitat selection by the Porcupine Caribou Herd (PCH) has not been examined. Investigating temporal variance in habitat selection may clarify the time period when managers may accurately estimate calving-related habitat selection. Annually, 1992-1994, approximately 70 calves were radio-collared within 2 days of birth and relocated daily until departing the calving grounds. We used daily 99% fixed kernel utilization distributions (UD's) to estimate caribou distributions, then estimated daily habitat selection using logistic regression. Habitat variables included relative vegetation greenness, greening rate, landcover class, and elevation. Spatial scales of investigation included concentrated vs. peripheral use within daily UD's, daily use within the merged extent of all daily UD's, and daily use within the historical extent of calving, 1983-2001. We used linear regression of logistic regression parameter estimates on sequential sampling days to estimate temporal habitat selection trends during the 3 weeks following capture. Overall, caribou exhibited habitat selection at multiple scales, without temporal trends, suggesting that the 21-day period following capture constituted a single domain and that managers may accurately estimate calving-related habitat selection at any point during this period"--Leaf iii.

Download or read book Caribou and the North written by Monte Hummel and published by Dundurn. This book was released on 2008-08-18 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: "If the caribou die, then we die." These few words speak eloquently to the significanceof caribou for northern peoples. They were spoken not by a wise old chief, but by a 13-year-old Dene youth in 2007 during a hearing regarding uranium exploration on the caribou wintering grounds. Right now there is urgent, widespread concern about the future of the most centralof species: caribou. Caribou and the North brings both the facts and the feelingsof the current situation to a North American readership. The writers look at why we need to conserve the caribou, the threats that have faced caribou in the past, present, and future, and the actions that we can take. Also included is an appendixwith up-to-date information on the range, movements, habitats, numbers, population trends, and key threats to caribou in North America.

Download or read book Caribou Herds of Northwest Alaska 1850 2000 written by Ernest S. Burch Jr. and published by University of Alaska Press. 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.

Download or read book The Urban Whale written by Scott D. Kraus and published by Harvard University Press. This book was released on 2009-01-01 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1980 a group of scientists censusing marine mammals in the Bay of Fundy was astonished at the sight of 25 right whales. It was, one scientist later recalled, "like finding a brontosaurus in the backyard." Until that time, scientists believed the North Atlantic right whale was extinct or nearly so. The sightings electrified the research community, spurring a quarter century of exploration, which is documented here. The authors present our current knowledge about the biology and plight of right whales, including their reproduction, feeding, genetics, and endocrinology, as well as fatal run-ins with ships and fishing gear. Employing individual identifications, acoustics, and population models, Scott Kraus, Rosalind Rolland, and their colleagues present a vivid history of this animal, from a once commercially hunted commodity to today's life-threatening challenges of urban waters. Hunted for nearly a millennium, right whales are now being killed by the ocean commerce that supports our modern way of life. This book offers hope for the eventual salvation of this great whale.

Available in PDF, EPUB and Kindle. Book excerpt: Humans, being visually oriented, are well versed in camouflage and how animals hide from predators that use vision to locate prey. However, many predators do not hunt by sight; they hunt by scent. This raises the question: do survival mechanisms and behaviors exist which allow animals to hide from these olfactory predators? If so, what are they, a

Download or read book Reindeer Husbandry and Global Environmental Change written by Tim Horstkotte and published by Taylor & Francis. This book was released on 2022-04-21 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume offers a holistic understanding of the environmental and societal challenges that affect reindeer husbandry in Fennoscandia today. Reindeer husbandry is a livelihood with a long traditional heritage and cultural importance. Like many other pastoral societies, reindeer herders are confronted with significant challenges. Covering Norway, Sweden and Finland – three countries with many differences and similarities – this volume examines how reindeer husbandry is affected by and responds to global environmental change and resource extraction in boreal and arctic social-ecological systems. Beginning with an historical overview of reindeer husbandry, the volume analyses the realities of the present from different perspectives and disciplines. Genetics, behavioural ecology of reindeer, other forms of land use, pastoralists’ norms and knowledge, bio-economy and governance structures all set the stage for the complex internal and externally imposed dynamics within reindeer husbandry. In-depth analyses are devoted to particularly urgent challenges, such as land-use conflicts, climate change and predation, identified as having a high potential to shape the future pathways of the pastoral identity and productivity. These futures, with their risks and opportunities, are explored in the final section, offering a synthesis of the comparative approach between the three countries that runs as a recurring theme through the book. With its richness and depth, this volume contributes significantly to the understanding of the substantial impacts on pastoralist communities in northernmost Europe today, while highlighting viable pathways to maintaining reindeer husbandry for the future. This book will be of great interest to students and scholars of both the natural and social sciences who work on natural resource management, global environmental change, pastoralism, ecology, social-ecological systems, rangeland management and Indigenous studies.
