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. J. Alfonso Ortega-S., is an associate professor at the Caesar Kleberg Wildlife Research Institute, Texas A&M University-Kingsville.
The original, 2006 edition of Timothy Edward Fulbright and J. Alfonso Ortega-S.’s White-Tailed Deer Habitat: Ecology and Management on Rangelands was hailed as “a splendid reference for the classroom and those who make their living from wildlife and the land” and as “filling a niche that is not currently approached in the literature.” In this second, full-color edition, revised and expanded to include the entire western United States and northern Mexico, Fulbright and Ortega-S. provide a carefully reasoned synthesis of ecological and range management principles that incorporates rangeland vegetation management and the impact of crops, livestock, predation, and population density within the context of the arid and semiarid habitats of this broad region. As landowners look to hunting as a source of income and to the other benefits of managing for wildlife, the clear presentation of the up-to-date research gathered in this book will aid their efforts. Essential points covered in this new edition include: White-tailed deer habitat requirements Nutritional needs of White-tailed deer Carrying capacity Habitat management Hunting Focused across political borders and written with an understanding of environments where periodic drought punctuates long-term weather patterns, this revised and expanded edition of White-Tailed Deer Habitat: Ecology and Management on Rangelands will aid landowners, researchers, and naturalists in their efforts to integrate land management and use with sound ecological practices.
Northern bobwhites are one of the most popular game birds in the United States. In Texas alone, nearly 100,000 hunters take to the field each fall and winter to pursue wild bobwhite quail. Texas is arguably the last remaining state with sufficient habitat to provide quail-hunting opportunities on a grand scale, and Texas ranchers with good bobwhite habitat often generate a greater proportion of their income from fees paid by quail hunters than from livestock production. Managing and expanding bobwhite habitat makes good sense economically, and it benefits the environment as well. The rangelands and woodlands of Texas that produce quail also support scores of other species of wildlife. Texas Bobwhites is a field guide to the seeds commonly eaten by northern bobwhites, as well as a handbook for conserving and improving northern bobwhite habitat. It provides identifying characteristics for the seeds of 91 species of grasses, forbs, woody plants, and succulents. Each seed description includes a close-up and a scale photo of the seed and the plant that produces it, along with a range map. Using this information, hunters can readily identify concentrations of plants that are most likely to attract quail. Landowners and rangeland managers will greatly benefit from the book's state-of-the-art guidance for habitat management and restoration, including improving habitat dominated by invasive and nonnative grasses.
When General Ulysses S. Grant targeted Forts Henry and Donelson, he penetrated the Confederacy at one of its most vulnerable points, setting in motion events that would elevate his own status, demoralize the Confederate leadership and citizenry, and, significantly, tear the western Confederacy asunder. More to the point, the two battles of early 1862 opened the Tennessee River campaign that would prove critical to the ultimate Union victory in the Mississippi Valley. In Grant Invades Tennessee, award-winning Civil War historian Timothy B. Smith gives readers a battlefield view of the fight for Forts Henry and Donelson, as well as a critical wide-angle perspective on their broader meaning in the conduct and outcome of the war. The first comprehensive tactical treatment of these decisive battles, this book completes the trilogy of the Tennessee River campaign that Smith began in Shiloh and Corinth 1862, marking a milestone in Civil War history. Whether detailing command-level decisions or using eye-witness anecdotes to describe events on the ground, walking readers through maps or pulling back for an assessment of strategy, this finely written work is equally sure on matters of combat and context. Beginning with Grant's decision to bypass the Confederates' better-defended sites on the Mississippi, Smith takes readers step-by-step through the battles: the employment of a flotilla of riverine war ships along with infantry and land-based artillery in subduing Fort Henry; the lesser effectiveness of this strategy against Donelson's much stronger defense, weaponry, and fighting forces; the surprise counteroffensive by the Confederates and the role of their commanders' incompetence and cowardice in foiling its success. Though casualties at the two forts fell far short of bloodier Civil War battles to come, the importance of these Union victories transcend battlefield statistics. Grant Invades Tennessee allows us, for the first time, to clearly see how and why.
Feelings of worthlessness. Low self-esteem. Illegitimate guilt. The inability to forgive. Bitterness and resentment. Dependency. Unhealthy relationship patterns. These battles rage within the minds of millions of people, including Christians. Although these may be mistaken as private battles, they are part of a much larger battle--the battle between Christ and Satan, the battle for our hearts and minds. Fortunately the battle is not lost. In Could It Be This Simple? A Biblical Model for Healing the Mind you'll learn about God's original ideal for the mind and His beautiful plan to restore His children back into His image. Psychiatrist Timothy R. Jennings also exposes many of Satan's subtle tactics that interfere with God's plan to heal the mind. Armed with the tools provided in this book, you can cooperate better with God to achieve emotional and mental well-being and gain real spiritual victory.

At long last the approach that has helped thousands of learners memorize Japanese kanji has been adapted to help students with Chinese characters. Book 1 of Remembering Traditional Hanzi covers the writing and meaning of the 1,000 most commonly used characters in the traditional Chinese writing system, plus another 500 that are best learned at an early stage. (Book 2 adds another 1,500 characters for a total of 3,000.) Of critical importance to the approach found in these pages is the systematic arranging of characters in an order best suited to memorization. In the Chinese writing system, strokes and simple components are nested within relatively simple characters, which can, in turn, serve as parts of more complicated characters and so on. Taking advantage of this allows a logical ordering, making it possible for students to approach most new characters with prior knowledge that can greatly facilitate the learning process. Guidance and detailed instructions are provided along the way. Students are taught to employ "imaginative memory" to associate each character’s component parts, or "primitive elements," with one another and with a key word that has been carefully selected to represent an important meaning of the character. This is accomplished through the creation of a "story" that engagingly ties the primitive elements and key word together. In this way, the collections of dots, strokes, and components that make up the characters are associated in memorable fashion, dramatically shortening the time required for learning and helping to prevent characters from slipping out of memory.
A comprehensive layout design workshop that assumes that in order to effectively break the rules of grid-based design, one must first understand those rules.

In 2003, a cadre of researchers set out to determine what combination of supplemental or natural nutrition and white-tailed deer population density would produce the largest antlers on bucks without harming vegetation. They would come to call this combination “the sweet spot.” Over the course of their 15-year experiment, conducted through the Caesar Kleberg Wildlife Research Institute at Texas A&M University–Kingsville, Timothy E. Fulbright, Charles A. DeYoung, David G. Hewitt, Don A. Draeger, and 25 graduate students tracked the effects of deer density and enhanced versus natural nutrition on vegetation conditions. Through wet years and dry, in a semiarid environment with frequent droughts, they observed deer nutrition and food habits and analyzed population dynamics. Containing the results of this landmark, longitudinal study, in keeping with the Kleberg Institute’s mission, this volume provides science-based information for enhancing the conservation and management of Texas wildlife. Advanced White-Tailed Deer Management: The Nutrition–Population Density Sweet Spot presents this critical research for the first time as a reference for hunters, landowners, wildlife managers, and all those who work closely with white-tailed deer populations. It explains the findings of the Comanche-Faith Project and the implications of these findings for white-tailed deer ecology and management throughout the range of the species with the goal of improving management.
From apple pie to baklava, cannoli to gulab jamun, sweet treats have universal appeal in countries around the world. This encyclopedia provides a comprehensive look at global dessert culture. Few things represent a culture as well as food. Because sweets are universal foods, they are the perfect basis for a comparative study of the intersection of history, geography, social class, religion, politics, and other key aspects of life. With that in mind, this encyclopedia surveys nearly 100 countries, examining their characteristic sweet treats from an anthropological perspective. It offers historical context on what sweets are popular where and why and emphasizes the cross-cultural insights those sweets present. The reference opens with an overview of general trends in desserts and sweet treats. Entries organized by country and region describe cultural attributes of local desserts, how and when sweets are enjoyed, and any ingredients that are iconic. Several popular desserts are discussed within each entry including information on their history, their importance, and regional/cultural variations on preparation. An appendix of recipes provides instructions on how to make many of the dishes, whether for school projects or general entertaining.
