Towering over deserts, arid scrublands, and dry tropical forests, giant cacti grow throughout the Americas, from the United States to ArgentinaÑoften 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 Guarij’os, Mayos, and Seris of MexicoÑpeoples for whom such cacti have been indispensable to survivalÑhe 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 foundÑfrom sea-level deserts to frigid Andean heightsÑYetman 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 growÑand that foster human life in otherwise impossible places.

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.

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).

Park S. Nobel pioneered the coupling of cellular physical chemistry with plant physiology, providing a sound physicochemical interpretation of the laws of diffusion to a rapidly expanding field of plant physiological ecology. His classical textbook is the only one of its kind to provide an extensive array of quantitative problems and solutions in the field of plant biophysics and ecophysiology, extending from the molecular to the ecological level. In this festschrift, former graduate students and postdocs, as well as colleagues of Prof. Nobel present a series of reviews that include scales from sub-cellular to global, and topics that range from desert succulent biology to the physiology of alpine plants, encompassing basic research and applications in agronomy and conservation biology. This state-of-the-field survey provides current and useful information for professionals and graduate students, while illustrating the broad span of the influence that Nobel's career has had on modern ecophysiology.

With more than two hundred species distributed from California through Texas and across most of mainland Mexico, Central and South America, and islands in the Caribbean Sea, the Phyllostomidae bat family (American leaf-nosed bats) is one of the world’s most diverse mammalian families. From an insectivorous ancestor, species living today, over about 30 million years, have evolved a hyper-diverse range of diets, from blood or small vertebrates, to consuming nectar, pollen, and fruit. Phyllostomid plant-visiting species are responsible for pollinating more than five hundred species of neotropical shrubs, trees, vines, and epiphytes—many of which are economically and ecologically important—and they also disperse the seeds of at least another five hundred plant species. Fruit-eating and seed-dispersing members of this family thus play a crucial role in the regeneration of neotropical forests, and the fruit eaters are among the most abundant mammals in these habitats. Coauthored by leading experts in the field and synthesizing the latest advances in molecular biology and ecological methods, Phyllostomid Bats is the first overview in more than forty years of the evolution of the many morphological, behavioral, physiological, and ecological adaptations in this family. Featuring abundant illustrations as well as details on the current conservation status of phyllostomid species, it is both a comprehensive reference for these ecologically vital creatures and a fascinating exploration of the evolutionary process of adaptive radiation.

What are the evolutionary mechanisms and ecological implications behind a pollinator choosing its favourite flower? Sixty-five million years of evolution has created the complex and integrated system which we see today and understanding the interactions involved is key to environmental sustainability. Examining pollination relationships from an evolutionary perspective, this book covers both botanical and zoological aspects. It addresses the puzzling question of co-speciation and co-evolution and the complexity of the relationships between plant and pollinator, the development of which is examined through the fossil record. Additional chapters are dedicated to the evolution of floral displays and signalling, as well as their role in pollination syndromes and the building of pollination networks. Wide-ranging in its coverage, it outlines current knowledge and complex emerging topics, demonstrating how advances in research methods are applied to pollination biology.

This updated and expanded A New Island Biogeography of the Sea of Cortés, 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 upcoming years of the biologically fascinating Sea of Cortés 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 Cortés, past accomplishments and conservation needs as yet outstanding. This book should be of strong interest to conservation biologists, ecologists, and evolutionary biologists more generally.

The desert islands of the Gulf of California are among the world's best-preserved archipelagos. The diverse and unique flora, from the cardón forests of Cholludo to the agave-dominated slopes of San Esteban remain much as they were centuries ago, when the Comcaac (Seri people) were the only human presence in the region. Almost 400 plant species exist here, with each island manifesting a unique composition of vegetation and flora. For thousands of years, climatic and biological forces have sculpted a set of unparalleled desert worlds. Plant Life of a Desert Archipelago is the first in-depth coverage of the plants on islands in the Gulf of California found in between the coasts of Baja California and Sonora. The work is the culmination of decades of study by botanist Richard Felger and recent investigations by Benjamin Wilder, in collaboration with Sr. Humberto Romero-Morales, one of the most knowledgeable Seris concerning the region's flora. Their collective effort weaves together careful and accurate botanical science with the rich cultural and stunning physical setting of this island realm. The researchers surveyed, collected, and studied thousands of plants—seen here in meticulous illustrations and stunning color photographs—providing the most precise species accounts of the islands ever made. To access remote parts of the islands the authors worked directly with the Comcaac, an indigenous community who have lived off marine and terrestrial life in this coastal desert region for centuries. Invaluable information regarding indigenous names and distributions are an intrinsic part of this work. The flora descriptions are extraordinarily detailed and painstakingly crafted for field biologists. Conservationists, students, and others who are interested in learning about the natural wealth of the Gulf of California, desert regions, or islands in general are sure to be captivated by this rich and fascinating volume.

Pollinators--insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction--are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

Agricultural systems are no longer evaluated solely on the basis of the food they provide, but also on their capacity to limit impacts on the environment, such as soil conservation, water quality and biodiversity conservation, as well as their contribution to mitigating and adapting to climate change. In order to cope with these multiple service functions, they must internalize the costs and benefits of their environmental impact. Payments for ecosystem services are hoped to encourage and promote sustainable practices via financial incentives. The authors show that while the principle is straightforward, the practice is much more complicated. Whereas scenic beauty and protection of water sources provide benefits to the local population, carbon sequestration and biodiversity conservation can be considered international public goods, rendering potential payment schemes more complex. Few examples exist where national or international bodies have been able to set up viable mechanisms that compensate agricultural systems for the environmental services they provide. However this book provides several examples of successful programs, and aims to transfer them to other regions of the world. The authors show that a product can be sold if it is clearly quantified, there exists a means to determine the service's values, and there is a willing buyer. The first two sections of the book present methodological issues related to the quantification and marketing of ecosystem services from agriculture, including agroforestry. The third and final section presents case studies of practical payments for ecosystem services and experiences in Central and South America, and draws some lessons learnt for effective and sustainable development of ecosystem services compensation mechanisms.
