Book Synopsis The Natural History of an Arctic Oil Field by : Joe C. Truett
Download or read book The Natural History of an Arctic Oil Field written by Joe C. Truett and published by Elsevier. This book was released on 2000-06-09 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: In spite of the harsh conditions that characterize the Arctic, it is a surprisingly fragile ecosystem. The exploration for oil in the Arctic over the past 30 years has had profound effects on the plants and animals that inhabit this frozen clime. The Natural History of an Arctic Oil Field synthesizes decades of research on these myriad impacts. Specialists with years of field experience have contributed to this volume to create the first widely available synopsis of the ecology and wildlife biology of animals and plants living in close association with an actively producing oil field. First widely available synthesis of arctic oil field ecology and wildlife biology Concise yet readable treatment of a diverse polar ecosystem Useful for land managers, policy makers as well as ecologists, and population biologists Chapters authored by recognized authorities and contributions are peer-reviewed for accuracy and scientific rigor Illustrations attractively designed to enhance comprehension

Book Synopsis Factors Influencing the Distribution of Bathurst Barren-ground Caribou (Rangifer Tarandus Groenlandicus) During Winter by : Tara A. Barrier
Download or read book Factors Influencing the Distribution of Bathurst Barren-ground Caribou (Rangifer Tarandus Groenlandicus) During Winter written by Tara A. Barrier and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Across the circumpolar north, many herds of Rangifer have decreased in abundance. In the Canadian central Arctic, the Bathurst herd of barren-ground caribou (Rangifer tarandus groenlandicus) declined from 472,000 ± 72,900 (± 95% confidence interval) caribou in 1986 to 31,900 ± 10,900 caribou in 2009 ...A reduction in winter forage due to forest fires has been suggested as a factor contributing to the decline. I employed a multi-scale study design to identify the influence of vegetation, fire history, snow cover, and predation risk on the occupancy of winter habitats by Bathurst caribou. Between 2008 and 2009, I collected forest stand and understory data at habitats used by caribou, as well as paired control sites. At a larger spatial scale, I used animal location data recorded from 1996 - 2009 to characterize the spatial and temporal distribution of Bathurst caribou on the winter range. At the scale of the feeding patch, caribou foraged in habitats with a high-percentage ground cover, high biomass of lichen, and few or small trees. Similarly, the consensus among the models of habitat selection was that collared caribou avoided areas of the winter range with a high density of burns and favoured older patches of forest characterized by a high percentage of ground cover of lichen and herbaceous forage and a close proximity to lakes and rivers. However, there was considerable use of habitats adjacent to the burn boundary, and some caribou occupied early-seral habitats significantly more than expected. Although the abundance of fruticose (having branched, shrubby thalli) lichens was relatively high (2464 kg/ha) in areas burned within the last 43 - 264 years, my results suggest that an increased incidence and severity of forest fires due to climatic warming could cause a temporary decrease in the habitat available to the Bathurst caribou herd during winter. In the event that reduced lichen availability becomes a limiting or regulating factor for caribou, fire suppression may be necessary to mitigate other climate- and anthropogenic-related pressures affecting the popualtion and distribution dynamics of Bathurst caribou."--P. ii-iii.

Available in PDF, EPUB and Kindle. Book excerpt: Migration is one of the world's great natural wonders and the scale of some migratory journeys is astounding. Yet migration is globally imperiled and effective conservation of the remaining migrations will require a thorough understanding of the drivers and mechanisms underlying how migrants complete such journeys. In this dissertation, I present three chapters that sought to better understand spring and autumn migration for the Western Arctic Herd, a population of barren-ground caribou (Rangifer tarandus) that complete some of the longest terrestrial migrations on the planet. In the first chapter, I applied and validated an analytical method to infer parturition events from GPS data with robust statistical confidence. In the second chapter, I examined the parturition events detected with these methods to better understand the drivers and mechanisms of spring migration because the calving grounds are the destination for pregnant females in spring. I quantified annual spatial patterns of calving and assessed what environmental factors influenced calving site selection by caribou through time. I found evidence of both memory and perception influencing spring migration, such that caribou use memory to return to an area of generally high-quality forage at the time of calving, and consequently adjust calving sites each year based on experienced conditions. In the third chapter, I sought to understand the environmental cues caribou respond to in deciding when to migrate in autumn. I found that decreasing temperatures and the timing of first snowfall events of the season had the greatest influence on migratory movements, but notably, caribou re-assessed decisions throughout the migration period as the conditions they experience changed. I also found that the cues caribou used are similar across individuals despite the herd being broadly dispersed in late summer, and the variability in migration timing observed each year is likely due to variability in environmental conditions experienced across the range. These findings pertaining to the drivers and mechanisms of migratory behavior, and broader aspects of movements by caribou, are highly relevant for conservation and management of the species across the circumpolar North. Moreover, the observation that caribou movement exhibits strong responses to particular climate phenomena, such as temperature and precipitation, have important implications for how caribou might respond as the climate of the Arctic continues to change.
