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.

This book was released on 2013 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ruminants have a highly specialized digestive system which allows them to obtain nutrients from fibrous forage. The morphology of this digestive system changes with respect to the quality and quantity of consumed forage. Few studies have explicitly examined variation in ruminant digestive system morphology in semi-arid environments at low latitudes. The aim of my dissertation was to examine scaling relationships of anatomical and physiological rumen-reticulum attributes, dietary nutrition, rumen- reticulum fill, reserve capacity, and surface area of rumen mucosa across a body mass gradient of white-tailed deer in a semi-arid environment. My findings indicate that scaling relationships between body mass and rumen-reticulum capacity were isometric. With regard to nutrition, juveniles and sub-adults consumed a higher quality diet (assessed by the ratio of protein to less digestible and indigestible carbohydrates), which should aid in meeting their high mass-specific metabolic demands. Factors governing rumen-reticulum function were complex because rumen-reticulum fill, reserve capacity, and absorptive surface area of the rumen mucosa were influenced by differing factors. One key finding was that surface area of the rumen mucosa had and inverse relationship with reserve capacity. This inverse relationship would allow individuals in a semi-arid environment to conserve metabolically expensive rumen-reticulum tissue, yet still allow them to accommodate sudden changes in forage quality. Additionally, my research indicates that white-tailed deer in a semi-arid environment had less pronounced seasonal changes in their surface area of rumen mucosa than deer at higher latitudes. My findings contain relevant information to intraspecific scaling relationships, forage niche partitioning, and anatomical patterns of the rumen-reticulum of deer inhabiting semi-arid environments.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hunters and management agencies are often interested in whole mass of harvested white-tailed deer (Odocoileus virginianus) but measuring whole mass in the field is challenging, which is why hunters often dress deer. Dressed mass consists of the carcass mass minus organs in the abdominal, thoracic, pelvic cavities as well as any blood loss. Dressed mass is strongly related to whole mass but covariates of site where deer was harvested, age, sex, body fat, and lactation state of females might also improve predicting whole mass. Also, gut fill variation should help explain why some covariates are influential. Using data from three different sites, which contained deer of various ages, sexes, and lactation states of females, I analyzed the effects of site, age, sex, body fat, lactation state of females, and gut fill on relationships between dressed mass and whole mass (n = 432). Rumen-reticulum fill served as my surrogate of gut fill because these compartments comprise 50 - 70 percent of gut capacity. I analyzed linear regression models and compared them for fit and parsimony with a Bayesian Information Criterion model selection analysis. The selected model had statistically significant predictors of dressed mass, age, sex, lactation status of females, and site. Gut fill also influenced dressed mass - whole mass relationships. Variation in gut fill across sites and due to age, sex, and lactation status of females was consistent with effects of these covariates on dressed mass - whole mass relationships. Lastly, I standardized variables in the selected model to have a mean of zero and standard deviation of one to assess the extent of influence of dressed mass and covariates on whole mass. Dressed mass had a much larger influence on whole mass than covariates. Although site, age, sex, and lactation status of females are influential, the improvement in predicting whole mass is slight. First and foremost, to accurately predict the whole mass of small to large deer requires measuring animals that range widely in dressed body mass.

This book was released on 2012-12-06 with total page 856 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two questions could not be avoided in the avant-propos of this book; (i) what is the importance to man of ruminant livestock, and (ii) what results of practical relevance in the growing mountain of scientific verbiage could be found in the Proceedings of this Symposium. Herbivores are an integral and critical part of the natural ecosystem which must be preserved because of their impact on human welfare. Wh at makes ruminants especially important to man is that they can thrive on fibrous forage and are thus the only viable enterprise over much of the earth's surface where crop growing is impracti cable. They contribute a wide array of products in addition to 50000 000 tonnes ofmeat (1977) and represent a 'capital reserve' that can be drawn upon in times of emergency: milk for example (450000000 tonnes) can make the difference between subsistence and starvation. About 60% of the world's meat and 80 % of the milk are produced by one third of the world ruminant population in the developed regions and as much as 99 % of the power for agriculture is provided by the ruminant population in developing countries. For the next two decades, a probable increase by 30 % for . cattle and buffalo and more than 40 % for sheep and goats is expected by improving health, fertility, nutrition and genetic potential rather than feed resources.

Available in PDF, EPUB and Kindle. Book excerpt: For most of the last century, range management meant managing land for livestock. How well a landowner grew the grass that cattle ate was the best measure of success. In this century, landowners look to hunting and wildlife viewing for income; rangeland is now also wildlife habitat, and they are managing their land not just for cattle but also for wildlife, most notably deer and quail. Unlike other books on white-tailed deer in places where rainfall is relatively high and the environment stable, this book takes an ecological approach to deer management in the semiarid lands of Oklahoma, Texas, and northern Mexico. These are the least productive of white-tail habitats, where periodic drought punctuates long-term weather patterns. The book's focus on this landscape across political borders is one of its original and lasting contributions. Another is its contention that good management is based on ecological principles that guide the manager's thinking about: Habitat Requirements of White-Tailed Deer White-Tailed Deer Nutrition Carrying Capacity Habitat Manipulation Predators Hunting Timothy Edward Fulbright is a Regents Professor and the Meadows Professor in Semiarid Land Ecology at the Caesar Kleberg Wildlife Research Institute, Texas A&M University-Kingsville.

Download or read book Bioenergetics Of Wild Herbivores written by Robert J. Hudson and published by CRC Press. This book was released on 2018-01-18 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioenergetics is an emerging discipline which offers a more profound understanding of the ecology, behaviour, and evolution of wild herbivores. Increasingly, bioenergetic principles have been applied in management since they provide insight into population dynamics and are relevant to manipulation of habitats and assessment of the impacts of resource development. Growing interest in the agricultural potential of wild herbivores has provided further impetus. In spite of this promise, there are few comprehensive syntheses of the concept and its application to wild herbivores. This volume attempts to fill this need. This book provides a great amount of detail but its expressive aim is to lead us to the whole animal, to a herd, to population as integral parts of an ecological entity which in turn is the result of evolutionary forces.The concept of this book promises the realization of an overdue change in the approach to bioenergetics, to nutrition and husbandry, and thus to the management of wild herbivores: the final emancipation from rules and views based primarily on domesticated herbivores or on experimental animals held under unnatural conditions, necessarily impending them behaviourally, physically, and psychically.
