This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Factors affecting morphometrics and epiphyseal closure are important in understanding regional variation and growth of white-tailed deer (Odocoileus virginianus). I compared body and antler growth from birth to 3 years of age in captive, first-generation, male white-tailed deer from three regions with varying soil quality and deer morphometrics. I also determined gender and age effects on epiphyseal closure timing in captive white-tailed deer. I found regional morphological variation present in first-generation male deer, which may be caused by regional genetic variation or lingering maternal effects. Determining cause of regional morphological variation will require data collection through a second-generation of males raised on the controlled diet. Epiphyseal closure timing was associated positively with age. Two of the four epiphyseal plates examined were affected by gender, with females closing prior to males. Morphometric and epiphyseal data confirm that age and gender affect epiphyseal closure timing in white-tailed deer.
Download or read book Maternal Factors Affect Individual and Population Level Morphometrics of Captive Male White tailed Deer Odocoileus Virginianus written by Eric S. Michel and published by . This book was released on 2016 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maternal factors have the potential to influence the morphometrics of offspring; however, the magnitude and persistence of those influences are not well known. I investigated the extent to which maternal factors influenced offspring phenotype at the individual and population level for captive white-tailed deer (Odocoileus virginianus) originating from three distinct physiographic regions of Mississippi, USA. First, I tested whether male white-tailed deer displayed improvements in weaponry and body size after two generations of being released from nutritional restrictions. I found that improved nutrition positively influenced all morphometrics; however, we observed variation in magnitude of improvement. Antler size was most responsive to improved nutrition while body mass and skeletal structures were less responsive; potentially indicating an adaptive strategy allowing males to increase yearly reproductive success without jeopardizing lifetime reproductive success. Second, we assessed whether maternal characteristics, early life characteristics or a combination of both persistently influenced morphometrics throughout maturity. I found that late birth date positively influenced offspring body mass through three-years of age; indicating that late-born fawns over-compensated for a late start to life. I also identified an indirect silver-spoon effect as early-, heavy-born fawns were heavy juveniles. In turn, heavy juveniles were also heavy adults. Therefore, male white-tailed deer may gain reproductive opportunities by displaying one of two strategies to increase body mass. Lastly, I estimated heritability for six antler characteristics and quantified the influence of maternal factors such as parturition date and litter size on the predictability of antler size. All antler characteristics were highly heritable. Yearling antler size was a moderate predictor of antler size later in life, but accounting for maternal factors greatly improved predictability. The influence of maternal factors decreased with increasing male age suggesting that compensation for the negative influence of maternal factors may occur after an individual's first year of life. My results suggest that although antler characteristics are highly heritable, the large influence of maternal factors on predictability indicates that use of yearling antler size as selective harvest criteria may not achieve all management goals.

Download or read book Recent Advances in Ageing and Sexing Animal Bones written by Deborah Ruscillo and published by Oxbow Books. This book was released on 2015-06-30 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume in the ICAZ series deals with the technical advances made over the last twenty years in the field of ageing and sexing animal bones. The analysis of ancient DNA holds great possibilities for sexing certain faunal assemblages (though by no means all), which is an urgent issue in the study of hunting and animal husbandry. It can be assumed that our forebears used more subtle taxonomic criteria than we do today, and it is important therefore that we are able to recognise traits that will allow for more accurate classification in terms of calendar age or sex. The eighteen papers in this book examine the state of research for various techniques of age/sex determination and assess potential future development.

Available in PDF, EPUB and Kindle. Book excerpt: Winner of the Wildlife Society Outstanding Edited Book Award for 2013! Winner of the Texas Chapter of The Wildlife Society Outstanding Book Award for 2011! Winner of a CHOICE Outstanding Academic Title Award for 2011! Biology and Management of White-tailed Deer organizes and presents information on the most studied large mammal species in the world. The book covers the evolutionary history of the species, its anatomy, physiology, and nutrition, population dynamics, and ecology across its vast range (from central Canada through northern South America). The book then discusses the history of management of white-tailed deer, beginning with early Native Americans and progressing through management by Europeans and examining population lows in the early 1900s, restocking efforts through the mid 1900s, and recent, overabundant populations that are becoming difficult to manage in many areas. Features: Co-published with the Quality Deer Management Association Compiles valuable information for white-tailed deer enthusiasts, managers, and biologists Written by an authoritative author team from diverse backgrounds Integrates white-tailed deer biology and management into a single volume Provides a thorough treatment of white-tailed deer antler biology Includes downloadable resources with color images The backbone of many state wildlife management agencies' policies and a featured hunting species through much of their range, white-tailed deer are an important species ecologically, socially, and scientifically in most areas of North America. Highly adaptable and now living in close proximity to humans in many areas, white-tailed deer are both the face of nature and the source of conflict with motorists, home-owners, and agricultural producers. Capturing the diverse aspects of white-tailed deer research, Biology and Management of White-tailed Deer is a reflection of the resources invested in the study of the species’ effects on ecosystems, predator-prey dynamics, population regulation, foraging behavior, and browser physiology.
Download or read book The Biology of Deer written by Robert D. Brown and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first International Conference on the Biology of Deer Production was held at Dunedin, New Zealand in 1983. That meeting provided, for the first time, a forum for those with interests in either wild deer management or farmed deer production to come together. Scientists, wild deer managers, domestic deer farmers, veterinarians, venison and antler product producers, and others were able to discuss common problems and to share their knowledge and experience. The relationships formed at that meeting, and the information amassed in the resulting Proceedings, sparked new endeavors in cervid research, management, and production. A great deal has taken place in the world of deer biology since 1983. Wild deer populations, although ever increasing in many areas of the world, face new hazards of habitat loss, environmental contamination, and overexploitation. Some species are closer to extinction than ever. Game managers often face political as well as biological challenges. Many more deer are now on farms, leading to greater concerns about disease control and increased needs for husbandry information. Researchers have accumulated considerable new in formation, some of it in areas such as biochemical genetics, not discussed in 1983.

Download or read book Nutrient Requirements of Nonhuman Primates written by National Research Council and published by National Academies Press. This book was released on 2003-03-01 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new release presents the wealth of information gleaned about nonhuman primates nutrition since the previous edition was published in 1978. With expanded coverage of natural dietary habits, gastrointestinal anatomy and physiology, and the nutrient needs of species that have been difficult to maintain in captivity, it explores the impact on nutrition of physiological and life-stage considerations: infancy, weaning, immune function, obesity, aging, and more. The committee also discusses issues of environmental enrichment such as opportunities for foraging. Based on the world's scientific literature and input from authoritative sources, the book provides best estimates of nutrient requirements. The volume covers requirements for energy: carbohydrates, including the role of dietary fiber; proteins and amino acids; fats and fatty acids; minerals, fat-soluble and water-soluble vitamins; and water. The book also analyzes the composition of important foods and feed ingredients and offers guidelines on feed processing and diet formulation.
Download or read book Anatomical Imaging written by Hideki Endo and published by Springer Science & Business Media. This book was released on 2009-02-05 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents selected works of contemporary evolutionary morphologists and includes such topics as broad scale reconstructions of the brain and ear of dinosaurs, inference of locomotor habits from cancellous bone architecture in fossil primates, and a comparison of the independently evolved manipulating apparatuses in the lesser and giant pandas. Insight is provided into the application of modern noninvasive technologies, including digital imaging techniques and virtual 3D reconstruction, to the investigation of complex anatomical features and coherences. In combination with traditional methods, this allows for the formulation of improved hypotheses on coordinated function and evolution. The creation of virtual translucent specimens makes it possible to realize the age-old dream of the classical anatomists: looking through the skin into the inner organization of an organism. On full display here is the dramatic and promising impact that modern imaging techniques have on scientific progress in evolutionary morphology.
Download or read book Wild Pigs in the United States written by John J. Mayer and published by University of Georgia Press. This book was released on 2008-03-01 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an estimated population of at least 500,000 distributed across nineteen states, the wild-living pig (Sus scrofa) is the most abundant free-ranging introduced ungulate in the United States. Until now, however, little has been known about the wild pig on a national scale, despite its abundance and significance as both a pest and a game animal. Whereas previous studies have been regional in scope, Wild Pigs in the United States is the most comprehensive work available on wild pig history, current status, comparative morphology, and other subjects important to the species' management and control. The information in this volume relates to the country's three prevalent wild pig types: the introduced Eurasian wild boar, the feral (once domestic, now wild) hog, and hybrids of the two. The first section of the book presents a history of wild pigs in this country-their origins; when, where, and by whom they were first introduced; and their subsequent dispersal. John J. Mayer and I. Lehr Brisbin, Jr. then develop specific criteria, based on taxonomic principles, for differentiating between the wild pig types. Employing numerous illustrations, graphs, and tables, they analyze and compare morphometric and discrete characters of the skull, external body dimensions and proportions, coat colorations patterns, and hair structure and form. A report on the status of wild pig populations in the United States (as of 1991) completes the volume. To profile the present ranges, habitats, and morphotypic makeups of wild pigs, the authors conducted two national surveys--in 1981 and 1988--among private individuals and federal and state personnel. Their report is also based on other recent wild pig studies and additional information from survey respondents. The book's reference section is particularly valuable, for its lists all sources consulted as well as the names and addresses of authorities the authors interviewed or with whom they corresponded. Aided by the book's wealth of current data, biologists and wildlife managers can make informed decisions about such issues as state versus private ownership of wild pig populations and the status of wild pigs as pests or game animals. In addition, hunters and sportsmen, zoologists, and even specialized historians and archaeologists will find Wild Pigs in the United States useful and informative.

Download or read book Bone Loss and Osteoporosis written by Sabrina C. Agarwal and published by Springer Science & Business Media. This book was released on 2011-06-28 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the growing incidence of fragility fractures in Europe and North America over the last three decades, bone loss and osteoporosis have become active areas of research in skeletal biology. Bone loss is associated with aging in both sexes and is accelerated in women with the onset of menopause. However, bone loss is related to a suite of complex and often synergistically related factors including genetics, pathology, nutrition, mechani cal usage, and lifestyle. It is not surprising that its incidence and severity vary among populations. There has been increasing interest to investigate bone loss and osteoporosis from an anthropological perspective that utilizes a biocultural approach. Biocultural approaches recognize the inter-relationship between biological, cultural, and environmental variables. Anthropological studies also highlight the value of evolutionary and population approaches to the study of bone loss. These approaches are particularly suited to elucidate the multifactorial etiology of bone loss. The idea for this volume came out of a symposium organized by the editors at the 70th annual meeting of The American Association of Physical Anthropologists in Kansas City, Missouri. Many of the symposium participants, along with several additional leading scientists involved in bone and osteoporosis research, are brought together in this volume. Each chapter focuses on a different aspect of bone loss and fragility with a fresh and stimulating perspective.
Download or read book Zoological Collections of Germany written by Lothar A. Beck and published by Springer. This book was released on 2018-02-05 with total page 730 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the knowledge of up to 250 years of collecting, organizing and preserving animals by generations of scientists. Zoological Collections are a huge resource for modern animal research and should be available for national and international scientists and institutions, as well as prospective public and private customers. Moreover, these collections are an important part of the scientific enterprise, supporting scientific research, human health, public education, and the conservation of biodiversity. Much of what we are beginning to understand about our world, we owe to the collection, preservation, and ongoing study of natural specimens. Properly preserved collections of marine or terrestrial animals are libraries of Earth's history and vital to our ability to learn about our place in its future. The approach employed by the editor involves not only an introduction to the topic, but also an external view on German collections including an assessment of their value in the international and national context, and information on the international and national collection networks. Particular attention is given to new approaches of sorting, preserving and researching in Zoological Collections as well as their neglect and/or threat. In addition, the book provides information on all big Public Research Museums, on important Collections in regional Country and local District Museums, and also on University collections. This is a highly informative and carefully presented book, providing scientific insight for readers with an interest in biodiversity, taxonomy, or evolution, as well as natural history collections at large.

Book excerpt: Willtown was founded in the late 17th century on the banks of the South Edisto River, but the movement of the Willtown Church in the 1760s to another location marked the demise of the town. Hugh C. Lane Jr. encouraged The Charleston Museum in its research in and around the Willtown area, asking the question, "Why did Willtown fail?" "Our serendipitous discovery of James Stobo's rice plantation a mile from Willtown revealed a site remarkable in its pristine preservation, the clarity of its stratigraphic record, the number and types of artifacts recovered, and in the complexity of its architectural detail."--Introduction, p. 1.
