Book Description
Although cacti such as the saguaro and organ pipe have come to define the Sonoran Desert for many people, they represent some 170 species of columnar cacti found in many parts of the Americas. These giant plants are so dominant in some ecosystems that many species of animals rely on them for food and shelter. They are pollinated by bats in central Mexico and Venezuela, by birds and bees in northern Mexico and Peru. This book summarizes our knowledge about the ecology, evolution, and conservation of columnar cacti and their vertebrate mutualists to show that the very survival of these cacti depends on animals who pollinate them and disperse their seeds. Contributors from the United States, Mexico, Venezuela, and Colombia explore aspects of geology and evolution that have forged this relationship, review findings in anatomy and physiology, and discuss recent research in population and community ecology as well as conservation issues. Ranging from the Sonoran Desert to the northern Andes, these studies reflect progress in understanding how abiotic and biotic factors interact to influence the evolution, distribution, and abundance of cacti and mutualists alike. In addition, this book examines the ways in which humans, through the process of domestication, have modified these plants for economic benefit. The contributors also review phylogenetic relationships between cacti and nectar-feeding bats in an effort to understand how bat-plant interactions have influenced the evolution of diversity and ecological specialization of both. Because of the number of migratory pollinators feeding on columnar cacti, the authors make conservation recommendations aimed at preserving fully functional ecosystems in arid portions of the New World tropics and subtropics. Columnar Cacti and Their Mutualists provided a benchmark for both conservation efforts and future research.

Book Description
Towering over deserts, arid scrublands, and dry tropical forests, giant cacti grow throughout the Americas, from the United States to Argentina—often in rough terrain and on barren, parched soils, places inhospitable to people. But as David Yetman shows, many of these tall plants have contributed significantly to human survival. Yetman has been fascinated by columnar cacti for most of his life and now brings years of study and reflection to a wide-ranging and handsomely illustrated book. Drawing on his close association with the Guarijíos, Mayos, and Seris of Mexico—peoples for whom such cacti have been indispensable to survival—he offers surprising evidence of the importance of these plants in human cultures. The Great Cacti reviews the more than one hundred species of columnar cacti, with detailed discussions of some 75 that have been the most beneficial to humans or are most spectacular. Focusing particularly on northwestern Mexico and the southwestern United States, Yetman examines the role of each species in human society, describing how cacti have provided food, shelter, medicine, even religiously significant hallucinogens. Taking readers to the exotic sites where these cacti are found—from sea-level deserts to frigid Andean heights—Yetman shows that the great cacti have facilitated the development of native culture in hostile environments, yielding their products with no tending necessary. Enhanced by over 300 superb color photos, The Great Cacti is both a personal and scientific overview of sahuesos, soberbios, and other towering flora that flourish where few other plants grow—and that foster human life in otherwise impossible places.

Book Description
In the darkness of the star-studded desert, bats and moths feed on the nectar of night-blooming cactus flowers. By day, birds and bees do the same, taking to blooms for their sweet sustenance. In return these special creatures pollinate the equally intriguing plants in an ecological circle of sustainability. The Sonoran Desert is the most biologically diverse desert in the world. Four species of columnar cacti, including the iconic saguaro and organ pipe, are among its most conspicuous plants. No Species Is an Island describes Theodore H. Fleming’s eleven-year study of the pollination biology of these species at a site he named Tortilla Flats in Sonora, Mexico, near Kino Bay. Now Fleming shares the surprising results of his intriguing work. Among the novel findings are one of the world’s rarest plant-breeding systems in a giant cactus; the ability of the organ pipe cactus to produce fruit with another species’ pollen; the highly specialized moth-cactus pollination system of the senita cactus; and the amazing lifestyle of the lesser long-nosed bat, the major nocturnal pollinator of three of these species. These discoveries serve as a primer on how to conduct ecological research, and they offer important conservation lessons for us all. Fleming highlights the preciousness of the ecological web of our planet—Tortilla Flats is a place where cacti and migratory bats and birds connect such far-flung habitats as Mexico’s tropical dry forest, the Sonoran Desert, and the temperate rain forests of southeastern Alaska. Fleming offers an insightful look at how field ecologists work and at the often big surprises that come from looking carefully at a natural world where no species stands alone.

Book Description
The saguaro, with its great size and characteristic shape—its arms stretching heavenward, its silhouette often resembling a human—has become the emblem of the Sonoran Desert of southwestern Arizona and northwestern Mexico. The largest and tallest cactus in the United States, it is both familiar and an object of fascination and curiosity. This book offers a complete natural history of this enduring and iconic desert plant. Gathering everything from the saguaro’s role in Sonoran Desert ecology to its adaptations to the desert climate and its sacred place in Indigenous culture, this book shares precolonial through current scientific findings. The saguaro is charismatic and readily accessible but also decidedly different from other desert flora. The essays in this book bear witness to our ongoing fascination with the great cactus and the plant’s unusual characteristics, covering the saguaro’s: history of discovery, place in the cactus family, ecology, anatomy and physiology, genetics, and ethnobotany. The Saguaro Cactus offers testimony to the cactus’s prominence as a symbol, the perceptions it inspires, its role in human society, and its importance in desert ecology.

Book Description
Lizards dashing rapidly between plants. Songbirds and woodpeckers flying to and from their nests. Hawks perched on saguaros. What kinds of journeys have these and many other animals and plants and their ancestors taken in space and time to arrive in the Sonoran Desert? How long have these species been living together here? In Sonoran Desert Journeys ecologist Theodore H. Fleming discusses two remarkable journeys. First, Fleming offers a brief history of our intellectual and technical journey over the past three centuries to understand the evolution of life on Earth. Next, he applies those techniques on a journey of discovery about the evolution and natural history of some of the Sonoran Desert’s most iconic animals and plants. Fleming details the daily lives of a variety of reptiles, birds, mammals, and plants, describing their basic natural and evolutionary histories and addressing intriguing issues associated with their lifestyles and how they cope with a changing climate. Finally, Fleming discusses the complexity of Sonoran Desert conservation. This book explores the evolution and natural history of iconic animals and plants of the northern Sonoran Desert through the eyes of a curious naturalist and provides a model of how we can coexist with the unique species that call this area home.

Book Description
The average kilometer of tropical rainforest is teeming with life; it contains thousands of species of plants and animals. As The Ornaments of Life reveals, many of the most colorful and eye-catching rainforest inhabitants—toucans, monkeys, leaf-nosed bats, and hummingbirds to name a few—are an important component of the infrastructure that supports life in the forest. These fruit-and-nectar eating birds and mammals pollinate the flowers and disperse the seeds of hundreds of tropical plants, and unlike temperate communities, much of this greenery relies exclusively on animals for reproduction. Synthesizing recent research by ecologists and evolutionary biologists, Theodore H. Fleming and W. John Kress demonstrate the tremendous functional and evolutionary importance of these tropical pollinators and frugivores. They shed light on how these mutually symbiotic relationships evolved and lay out the current conservation status of these essential species. In order to illustrate the striking beauty of these “ornaments” of the rainforest, the authors have included a series of breathtaking color plates and full-color graphs and diagrams.

Book Description
Deserts appear very fascinating during our short visits. However, the lives of plants and animals are very dif?cult under the harsh climatic conditions of high tempe- ture and scant water supply in deserts, sometimes associated with high concent- tions of salt. The editor of this book was born and brought up in the Great Indian Desert, and has spent much of his life studying the growth and metabolism of desert plants. It is very charming on a cool summer evening to sit at the top of a sand dune listening only to blowing air and nothing else. It has been my dream to prepare a volume on desert plants encompassing various aspects of desert plant biology. In this book, I have tried to present functional and useful aspects of the vegetation resources of deserts along with scienti?c input aimed at understanding and impr- ing the utility of these plants. The scant vegetation of deserts supports animal life and provides many useful medicines, timber and fuel wood for humans. Therefore, there are chapters devoted to medicinal plants (Chap. 1), halophytes (Chaps. 13, 14), and fruit plants (Chaps. 17, 20). Desert plants have a unique reproductive biology (Chaps. 9–11), well-adapted eco-physiological and anatomical charact- istics (Chap. 7), and specialised metabolism and survival abilities. These plants are dif?cult to propagate and pose many problems to researchers developing biote- nological approaches for their amelioration (Chaps. 18–20).

Book Description
Distinguished by its slender vertical branches, which resemble the tubes of a pipe organ, and growing to the imposing height of 15 to more than 30 feet, itÕs obvious how the organ pipe cactus got its name. In the United States, these spectacular and intriguing plants are found exclusively in a small area of the Sonoran Desert in the southwestern corner of Arizona. With a landscape marked by sharp, rocky slopes and daytime highs in the summer reaching 110 degrees Fahrenheit, the region is inhospitable for most ordinary life, whether plant or animal. But the organ pipe cactus is far from ordinary. Although it is the most common columnar cactus, it is so unusual in the United States that it is only one of three cacti to have a national preserve established to protect it. In this regard, it joins a select group of plantsÑincluding Joshua trees, redwoods, and sequoiasÑupon which that honor has been conferred. In this beautifully illustrated, large-format book, David Yetman provides an in-depth and comprehensive look at these intriguing and picturesque plants that most Americans will never have the opportunity to see. Chapters explore their ethnobotanical uses, their habitat, their distribution, and special conditions required for their germination, establishment, growth, and survival. Yetman also places the organ pipe in perspective as a member of a genus with at least twenty-three species, ranging from the prostrate Stenocereus eruca of Baja California to the 50-foot high giant S. chacalapensis of the coast of Oaxaca.

Book Description
This updated and expanded A New Island Biogeography of the Sea of Cortes, first published nearly 20 years ago, integrates new and broader studies encompassing more taxa and more complete island coverage. The present synthesis provides a basis for further research and exploration in upcomingyears of the biologically fascinating Sea of Cortes region. The Gulf region is increasingly being exploited, for its natural resources by way of marine fisheries, and for its stunning natural beauty by way of a burgeoning tourism industry. Further, the region's human population is increasing apace.It is appropriate, therefore, that this volume discusses these evolving circumstances, and the efforts of the Mexican government to regulate and manage them. The new Biogeography includes a section on the conservation issues in the Sea of Cortes, past accomplishments and conservation needs as yetoutstanding. This book should be of strong interest to conservation biologists, ecologists, and evolutionary biologists more generally.
