This book was released on 2012 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The northern mountain population (NMP) of woodland caribou (Rangifer tarandus caribou) was assessed by the Committee on Status of Endangered Wildlife in Canada (COSEWIC) as a species of special concern in 2002 and was listed as such under the federal Species at Risk Act (SARA) in 2004. In the preparation of a SARA management plan, demographic information on the 39 delineated caribou herds was required (Environment Canada 2011). The Bonnet Plume and Redstone are two of the larger northern mountain caribou herds residing in the Mackenzie Mountains shared by the Yukon and Northwest Territories (NWT). Survey data from these herds are lacking, however Environment and Natural Resources (ENR) has collected voluntary wildlife observation data from the Mackenzie Mountain Outfitters and clients since 1991. I used this time series observation data to explore demographic characteristics of the Bonnet Plume and Redstone herds. I found consistent differences between the two herds in the ratios of calves per 100 adult females and male:female but also surprising consistency within herds over the past 20 years"--P. i.

This book was released on 2018 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The northern mountain population (NMP) of woodland caribou was listed as a species of Special Concern under the federal Species at Risk Act in 2004 and the status was reaffirmed in 2014. The Redstone and the Bonnet Plume are two of the larger NMP herds shared by the Yukon and Northwest Territories. Aerial survey data from both of these herds are lacking. Data from voluntary wildlife observations, collected from Mackenzie Mountain Outfitters and their clients from 1991-2010, were used to explore demographic parameters of these herds prior to the 2014 Committee on the Status of Endangered Wildlife in Canada reassessment of NMP. The ratios of calves and adult males per 100 adult females were distinctly different between the two herds but showed remarkable consistency within herds over a 20 year period (Larter 2012). With an additional six more years of observation data, there is some evidence of decreasing trends in the ratio of calves per 100 adult females and percent calves. Conversely, there is some evidence of increasing trends in the ratio of adult males per 100 adult females. Additionally, the difference in demographic parameters between herds is becoming less distinct. These changes are discussed in relation to the overall time series and the time series partitioned into nine year generation periods for NMP.

This book was released on 2017-02-23 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: The existing theories on the evolution of senescence assume that senescence is inevitable in all organisms. However, recent studies have shown that this is not necessarily true. A better understanding of senescence and its underlying mechanisms could have far-reaching consequences for conservation and eco-evolutionary research. This book is the first to offer interdisciplinary perspectives on the evolution of senescence in many species, setting the stage for further developments. It brings together new insights from a wide range of scientific fields and cutting-edge research done on a multitude of different animals (including humans), plants and microbes, giving the reader a complete overview of recent developments and of the controversies currently surrounding the topic. Written by specialists from a variety of disciplines, this book is a valuable source of information for students and researchers interested in ageing and life history traits and populations.
Download or read book The Paleoanthropology and Archaeology of Big Game Hunting written by John D. Speth and published by Springer Science & Business Media. This book was released on 2010-09-08 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its inception, paleoanthropology has been closely wedded to the idea that big-game hunting by our hominin ancestors arose, first and foremost, as a means for acquiring energy and vital nutrients. This assumption has rarely been questioned, and seems intuitively obvious—meat is a nutrient-rich food with the ideal array of amino acids, and big animals provide meat in large, convenient packages. Through new research, the author of this volume provides a strong argument that the primary goals of big-game hunting were actually social and political—increasing hunter’s prestige and standing—and that the nutritional component was just an added bonus. Through a comprehensive, interdisciplinary research approach, the author examines the historical and current perceptions of protein as an important nutrient source, the biological impact of a high-protein diet and the evidence of this in the archaeological record, and provides a compelling reexamination of this long-held conclusion. This volume will be of interest to researchers in Archaeology, Evolutionary Biology, and Paleoanthropology, particularly those studying diet and nutrition.
Download or read book Responding to Oil Spills in the U S Arctic Marine Environment written by National Research Council and published by National Academies Press. This book was released on 2014-08-01 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: U.S. Arctic waters north of the Bering Strait and west of the Canadian border encompass a vast area that is usually ice covered for much of the year, but is increasingly experiencing longer periods and larger areas of open water due to climate change. Sparsely inhabited with a wide variety of ecosystems found nowhere else, this region is vulnerable to damage from human activities. As oil and gas, shipping, and tourism activities increase, the possibilities of an oil spill also increase. How can we best prepare to respond to such an event in this challenging environment? Responding to Oil Spills in the U.S. Arctic Marine Environment reviews the current state of the science regarding oil spill response and environmental assessment in the Arctic region north of the Bering Strait, with emphasis on the potential impacts in U.S. waters. This report describes the unique ecosystems and environment of the Arctic and makes recommendations to provide an effective response effort in these challenging conditions. According to Responding to Oil Spills in the U.S. Arctic Marine Environment, a full range of proven oil spill response technologies is needed in order to minimize the impacts on people and sensitive ecosystems. This report identifies key oil spill research priorities, critical data and monitoring needs, mitigation strategies, and important operational and logistical issues. The Arctic acts as an integrating, regulating, and mediating component of the physical, atmospheric and cryospheric systems that govern life on Earth. Not only does the Arctic serve as regulator of many of the Earth's large-scale systems and processes, but it is also an area where choices made have substantial impact on life and choices everywhere on planet Earth. This report's recommendations will assist environmentalists, industry, state and local policymakers, and anyone interested in the future of this special region to preserve and protect it from damaging oil spills.
Download or read book Bears of the World written by Vincenzo Penteriani and published by Cambridge University Press. This book was released on 2020-11-30 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bears have fascinated people since ancient times. The relationship between bears and humans dates back thousands of years, during which time we have also competed with bears for shelter and food. In modern times, bears have come under pressure through encroachment on their habitats, climate change, and illegal trade in their body parts, including the Asian bile bear market. The IUCN lists six bears as vulnerable or endangered, and even the least concern species, such as the brown bear, are at risk of extirpation in certain countries. The poaching and international trade of these most threatened populations are prohibited, but still ongoing. Covering all bears species worldwide, this beautifully illustrated volume brings together the contributions of 200 international bear experts on the ecology, conservation status, and management of the Ursidae family. It reveals the fascinating long history of interactions between humans and bears and the threats affecting these charismatic species.
Download or read book Information and Its Role in Hunter Gatherer Bands written by Robert K. Hitchcock and published by Cotsen Institute of Archaeology Press. This book was released on 2011-12-31 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information and its Role in Hunter-Gatherer Bands explores the question of how information, broadly conceived, is acquired, stored, circulated, and utilized in small-scale hunter-gatherer societies, or bands. Given the nature of this question, the volume brings together a group of scholars from multiple disciplines, including archaeology, ethnography, linguistics, and evolutionary ecology. Each of these specialties deals with the question of information in different ways and with different sets of data given different primacy. The fundamental goal of the volume is to bridge disciplines and subdisciplines, open discussion, and see if some common ground-either theoretical perspectives, general principles, or methodologies-can be developed upon which to build future research on the role of information in hunter-gatherer bands.
