Quality deer management (QDM) is widely accepted as a principled management practice, yet QDM implications for population processes are unclear. Our research primarily focused on components of (1) dispersal ecology and (2) the genetic mating system of white-tailed deer (Odocoileus virginianus) under QDM at Chesapeake Farms, Maryland. The objectives of our dispersal ecology research were: (1) to compare pre- and post-QDM dispersal parameter estimates, and (2) evaluate inbreeding avoidance and sexual-competition hypotheses as mechanisms of dispersal. Emigration of yearling males pre-QDM was 0.70 + 0.07, and post-QDM was 0.54 + 0.10. Genetic maternity analysis indicated that dispersal of orphans and non-orphans was similar. Dispersers exhibited breeding competition with other yearling males more often than nondispersers, and yearling male antler points appeared to be related to dispersal status in both pre- and post-QDM populations. Overall breeding behaviors of yearling males decreased from pre- to post-QDM. Our results fail to support inbreeding avoidance and support sexual-competition as a cause of fall dispersal at Chesapeake Farms. Through QDM, an older male age structure may have suppressed breeding competition in yearling males and decreased dispersal rates. The objectives of our genetic mating system research were to evaluate: (1) age-specific male breeding success; (2) relationships of weight and antler size with male breeding success; (3) instances of multiple paternity in single litters; and (4) male and female mate selection. We observed higher breeding success of males>3.5-years old in comparison to males

Easily the most common of America’s large wildlife species, white-tailed deer are often referred to as "overabundant." But when does a species cross the threshold from common to overpopulated? This question has been the focus of debate in recent years among hunters, animal rights activists, and biologists. William McShea and his colleagues explore every aspect of the issue in The Science of Overabundance. Are there really too many deer? Do efforts to control deer populations really work? What broader lessons can we learn from efforts to understand deer population dynamics? Through twenty-three chapters, the editors and contributors dismiss widely held lore and provide solid information on this perplexing problem.

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.

Think of deer and the image that pops into most American's minds is that of a white-tailed deer, the most common large mammal in North America. Most Europeans are more familiar with red deer. It may surprise many people to know that there are actually about 50 species of deer found throughout the world. Here, readers will find nontechnical, expert information about the wide range of diverse deer species. Did you know that elk and caribou are deer? Or that the earliest fossils of deer are 15 to 20 million years old? Have you ever wondered whether deer swim, play, or see color? How do deer avoid predators and survive the winter? Do deer make good pets or carry contagious diseases? George A. Feldhamer and William J. McShea answer these and other intriguing questions about members of the deer family Cervidae. From the diminutive pudu of South America that weighs 17 pounds to male moose that weigh close to 2,000 pounds, Feldhamer and McShea explore the biology, evolution, ecology, feeding habits, reproduction, and behavior of deer. They chronicle the relationships between humans and deer—both positive and negative—and discuss the challenges of deer conservation and management. With vivid color photographs and an accessible and engaging question-and-answer format, this easy-to-read book is the go-to resource on deer. Nature lovers, hunters, and anyone curious about deer will find this fact-filled book both fascinating and full of surprises.
