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 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.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antlers are a costly trait that require skeletal reserves to grow to a large size. Thus, insight into variation in antler size requires understanding the connection between antler and body size, which can be summarized through ontogenetic and static scaling relationships. Both types of scaling relationships are needed to examine the influence of factors besides body mass on antler growth at different ages and whether the influence of these factors diminish with age. Size deficits influenced by diet variability and maternal effects might decline during ontogeny through compensatory growth. I sought insight into the influences of diet and maternal attributes of mother's age at birth of offspring and litter size on body-antler size relationships throughout ontogeny and at discrete ages. I also examined whether diet and maternal effects diminished with age of males.

This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: White-tailed deer (Odocoileus virginianus) have been intensively studied across their range. However, many aspects of the white-tailed deer's ecology have not been studied or are difficult to study. The advent of global positioning system (GPS) collar technology and molecular genetics techniques now allows researchers to collect fine-scale and cryptic phenomena. In addition, selective harvest of male white-tailed deer, based on antler size, has not been critically evaluated. Thus, development and use of quantitative genetics models will be useful for elucidating the effects of selective harvest on mean population antler size. I used GPS collar technology to further understand white-tailed deer movement ecology. First, I determined the efficacy and influence of a high-tensile electric fence (HTEF) on deer movements. The HTEF controlled deer movements when properly maintained and had little influence on deer spatial dynamics, making it a safe and cost-effective alternative to traditional fencing. Second, I studied fine-scale deer movements using GPS collars collecting locations every 15 minutes. Hourly deer movements were greatest in the morning and evening. Parturition and rut influenced movements of females and males, respectively whereas weather and moon phase had minimal influence on movements. Molecular genetics techniques are becoming more widespread and accessible, which may allow insight into the link between genetics and antler size. I found deer in 3 diverse populations from Mississippi, Oklahoma and Texas were relatively heterozygous and unrelated. Groups of deer with similar antler characteristics did not appear to be inbred or share common ancestors. In addition, there was not a strong link between individual multi-locus heterozygosity and antler points or score. Selective harvest has been implicated in causing negative evolutionary and biological responses in several ungulate species. To better determine how selective harvest (i.e., culling; the removal of deer with inferior antlers) affects white-tailed deer antler size, I used quantitative genetic models to simulate response of deer antlers to selection. In simulated controlled breeding situations response to selection was rapid, resulting in improvement in antler size. In simulated free-ranging populations response of antler size to selection was slow and only resulted in minimal increases in antler points after 20 years.

Available in PDF, EPUB and Kindle. Book excerpt: Objective and accurate techniques are needed to estimate age and antler size of live white-tailed deer (Odocoileus virginianus), because these parameters are essential to many white-tailed deer management strategies. I developed and evaluated accuracy of methods for estimating age and antler size from photographs of live, male white-tailed deer using Geographic Information Systems (GIS). I estimated size of photographed, known-score mounted antlers accurately using a fixed-scale object and photographed, live deer using anatomical features. I determined if a series of morphometric ratios could be used to predict age of deer from photographs using a dichotomous key procedure. Mean percentage error for gross antler score was 6% using a single photograph at 0° or 45°. The dichotomous key procedure effectively separated age classes of photographed, live white-tailed deer. When grouping deer into 1, 2, 3, 4, or= 5 year age classes, the methodology respectively.

Available in PDF, EPUB and Kindle. Book excerpt: Zeke’s Theory: Unlocking the Whitetail Antler Growth Process By: Eric V. Zimmerman I have been told I have an obsessive type personally, and after reading my book, I think you all will agree. I became obsessed with aging whitetails in my teens, being shown by one of the PGC biologists what the 18-month-old’s tooth looks like along with a brief description on how to use tooth wear and dentine thickness to determine the ages of deer above 18 months of age. My civilian work life has always involved the processing of deer, and if I cut off the antlers of a buck brought in to be processed, I would slice open the cheek, pry open its mouth, and age that buck. I would also weigh the carcasses, and a few patterns did start to form between age, weight, and antler size, and it was not supporting what is considered common knowledge about bucks and how their antlers grow. In 1998, I shot this eight-point and in 2004my daughter shot this cute little six-point. I have been studying these two bucks ever since, believing that the difference in the size of the antlers between these two bucks is based on the month they were born in and wondering in theory if the smaller buck’s antler size ever catches up to the larger buck in the following years. What the evidence is showing is that in order to grow record book bucks, the adage that it takes a three-legged stool of nutrition, genetics, and age is incomplete. Rather, what it takes is a four-legged chair with the animal’s birth date being added to the list of nutrition, genetics, and age. The information I'm providing will be very helpful to game managers who are looking to grow record book class whitetails, as my evidence will show that the antlers of bucks born late in the fawning season will never catch up or reach their full potential, and it is doubtful that they will ever have more than eight points or score over 120 in their lifetime.

Book excerpt: This is a book about one of nature's most remarkable accomplishments. When deer grow antlers they are actually regenerating anatomically complex appendages - something that no other mammal can do. The rate at which antler elongate makes them the fastest growing structures in the animal kingdom. Profoundly affected by male hormones, these secondary sex characters grow into massive tumors if the deer possessing them is castrated. These and other unique characteristics have made antlers the focus of extensive scientific research that addresses some provocative questions: From what tissues do antlers develop? By what morphogenetic mechanisms are they regenerated every year? What social functions prompted their initial evolution? How are they influenced by hormones, and by the seasonal daylength fluctuations that regulate their annual replacement cycles? These and many other questions are considered in this comprehensive account of antlerology.Students of development, evolution, and behavior will find much to appreciate in this volume, as will ecologists, wildlife biologists, and zookeepers. It is a rich source of information for endocrinologists and physiologists interested in the relationship of antlers to the reproductive cycle. The orthopedists will find the study of antlers a valuable model of skeletal growth and bone disease, and the purported medicinal properties of velvet antlers will be a subject of interest to the pharmacologist.Deer Antlers: Regeneration, Function, and Evolution is as scientifically accurate as it is readable. It does not answer all questions about these unique appendages, but it is certain to arouse curiosity about the many unsolved problems of how antlers grow, die, and are shed in the course of a single year.

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.
