In this lively, historically accurate account, David E. Brown chronicles the demise of the grizzly bear in the Southwest. He presents the personal narratives of those who knew grizzlies, accounts of hunters and administrators in wildlife management agencies, and the popular legends and lore of the grizzly that one would hear around the campfire. Scientists, Southwest historians, and those interested in America's wildlife will appreciate this readable study of the bear's life history and of the unique spirit of adventure associated with the grizzly bear-a spirit that passed from southwest game ranges with the expirpation of the species in the first half of this century. This edition includes a new foreword by Charles Jonkel and a new preface, in which the author discusses the latest developments in the debate over the grizzly's place in the Southwest.

Biotic Communities catalogs and defines by biome, or biotic community, the region centered on Arizona, New Mexico, Sonora, Chihuahua, and Baja California Norte, plus California, Nevada, Utah, Colorado, Texas, Coahuila, Sinaloa, and Baja California Sur. Originally published in 1982 by the Boyce Thompson Southwestern Arboretum, this ambitious book is still a "must-have" for those working in natural resources management and ecological research, as well as non-specialists who wish to know more about a particular locale.Biotic Communities is arranged by climatic formation with a short chapter for each biome describing climate, physiognomy, distribution, dominant and common plant species, and characteristic vertebrates. Subsequent chapters contain careful descriptions of zonal subdivisions. The text is supplemented with over one hundred black and white photographs illustrating almost every community type.

The Gila Monster spends 99% of its life underground, making encounters with this lizard extremely rare. Sightings are infrequent even for the biologists who study them. When one does stumble upon a Gila Monster, however, this slow-moving lizard is not easily forgotten. Advertised by orange-and-black coloration and followed by stories of venomous power, the Gila Monster carries a mystique like that of few other animals.In this volume, authors David Brown and Neil Carmony dig out the tall tales, dispel the myths, and reveal the lizard’s true character. Through a collection of biological and historical facts mixed with entertaining stories, they have created an illuminating account of America’s largest and only poisonous lizard. Written in an engaging style, The Gila Monster is a fun and educational read for all who are intrigued by the Southwest and its most mysterious denizen.

Two key long-term energy trends are shifting the strategic balance between the United States and China, the world's superpower rivals in the 21st century: first, a domestic boom in U.S. shale oil and gas is dramatically boosting America's energy security; second, the frenetic and successful search for hydrocarbons in Africa is making it an increasingly crucial element in China's energy diversification strategy. America's increasing energy security and China's increased dependence on energy imports from Africa and the Middle East until well past 2040 despite its own shale discoveries will make Beijing's own increasing energy insecurity be felt even more acutely, pushing the People's Liberation Army to accelerate adoption of a "two ocean" military strategy that includes an enduring presence in the Indian Ocean as well as the Pacific Ocean.

"What is it about these borderland cats which has so fired up people? Scarcity combined with beauty explains some of the appeal. So does the animal’s legendary strength and power as befits its role as the region’s top predator. The jaguar’s neotropical origins also add to its mystique...But there is something more. That such a large cat is out there somewhere...invokes the depths of our imagination. Nor does it matter one whit that the chance of any one individual actually seeing one is almost nil. The thought of such a cat’s presence is enough in itself."—from the book In 1996 a rancher hunting mountain lions just north of the Arizona-Mexico border treed a jaguar. Instead of reaching for a rifle, the rancher went for his camera. Later that year another party photographed a jaguar in Arizona’s Baboquivari Mountains. These compelling photographs sparked public interest in jaguars and have resulted in calls for listing jaguars as an endangered species. Borderland Jaguars documents the human-jaguar contact in the Southwest and presents jaguar folklore from both sides of the border. But the book is primarily a natural history of the jaguar, and discusses its distribution, habitats, and hunting and breeding characteristics before concluding with a section on the status and management of borderland jaguars, and a proposed conservation plan. Written in an engaging style, and replete with a wealth of photographs, Borderland Jaguars is a wonderful introduction to this elusive resident of the Southwest.

The U.S. Africa Command (AFRICOM), newest of the six U.S. Department of Defense geographical combatant commands (CCMDs), was created in 2007 amid great controversy in both Africa and the United States over its location and mission. Over the last 5 years, AFRICOM has matured greatly, overcoming much of the initial resistance from African stakeholders through careful public messaging, and addressing most U.S. interagency concerns about the Command's size and proper role within the U.S. national security/foreign policy community. This Letort Paper describes the geostrategic, operational, and intellectual changes that explain why AFRICOM was created, and debunks three myths about AFRICOM: that it was created to "exploit" Africa's oil and gas riches, "blocks" China's rise in Africa, and that France "opposes" AFRICOM. The author concludes by raising five issues important to AFRICOM's future: 1) allocated forces to carry out short-term training engagements in Africa;...

Nearly two feet long with striking black, white, and red plumage, the Ivory-billed and Imperial Woodpeckers were two of the most impressive woodpeckers in the world. Both species were known to be in serious decline by the end of the nineteenth century and are likely extinct today, though occasional reports of sightings persist. While the Ivory-billed was one of the first endangered birds to receive intensive conservation attention, the efforts were too often misdirected, and too little, too late. Concern for the fate of the Imperial Woodpecker came even later and resulted in a similar fate. The probable extinction of two of North America's largest and most charismatic birds has much to teach us regarding conservation efforts, especially as many other species face similar problems. In closely examining the history of the decline and causes of extinction of the Ivory-billed and Imperial Woodpeckers, the authors offer explanations for the birds' demise and strategies for future conservation and research efforts that focus mainly on the deadly, though largely understated, role of human depredations.
