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.
"There is nothing in the world like this book. It should be in every library and on the bookshelves of all those interested in cacti. The book will be an important resource for plant physiology, agronomy, and horticulture classes at both the undergraduate and graduate level."—Bruce Smith, Brigham Young University "Cacti: Biology and Uses is a landmark publication of one of the world's most unique group of plants. Park Nobel, a leading authority on succulent plants, has assembled a collection of contributions that spans a wide range of issues extending from basic systematics, anatomy, physiology and ecology to considerations of conservation and human uses of this diverse group of plants. This nicely-produced and well-illustrated volume provides a resource that will be of great use to a wide range of scientists, practitioners, and enthusiasts of this plant group."—Harold Mooney, Paul S. Achilles Professor of Environmental Biology, Stanford University
An exploration of the explosive illegal trade in succulents and the passion that drives it Cacti and succulents are phenomenally popular worldwide among plant enthusiasts, despite being among the world’s most threatened species. The fervor driving the illegal trade in succulents might also be driving some species to extinction. Delving into the strange world of succulent collecting, The Cactus Hunters takes us to the heart of this conundrum: the mystery of how and why ardent lovers of these plants engage in their illicit trade. This is a world of alluring desires, where collectors and conservationists alike are animated by passions that at times exceed the limits of law. What inspires the desire for a plant? What kind of satisfaction does it promise? The answer, Jared D. Margulies suspects, might be traced through the roots and workings of the illegal succulent trade—an exploration that traverses the fields of botany and criminology, political ecology and human geography, and psychoanalysis. His globe-spanning inquiry leads Margulies from a spectacular series of succulent heists on a small island off the coast of Mexico to California law enforcement agents infiltrating a smuggling ring in South Korea, from scientists racing to discover new and rare species before poachers find them to a notorious Czech “cacto-explorer” who helped turn a landlocked European country into the epicenter of the illegal succulent trade. A heady blend of international intrigue, social theory, botanical lore, and ecological study, The Cactus Hunters offers complex insight into species extinction, conservation, and more-than-human care.

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.
This dictionary will present all currently accepted generic, specific, sub-specific and variety names of trees, excluding fossil and more recently extinct taxa, hybrids and cultivars. Only the indigenous trees of a continent, those wild species that were natural elements of the spontaneous forest vegetation before the arrival of Europeans or other colonizers, are included.Each generic entry includes the family to which it is assigned, the synonyms of the Latin name, and the English, French, Spanish, trade and other names. For the English and French names the standard name is listed first, followed by other available names with, in parentheses, the countries where they are used. Where appropriate, names in additional languages are also included.Each infrageneric (species, subspecies, variety) entry includes, in addition, the distribution, height, type of foliage, ecological characteristics and main uses of the tree when available.In this volume only taxa indigenous on the North American continent are included, considered in a geographical, not in a political sense. This means from Alaska and Greenland to Panama, including Caribbean, but excluding Hawaii.
This book is the first comprehensive guide to Florida's amazing variety of tree species: from scrub oak on the high central ridges to mangroves stretching along the southern coasts, from mighty live oaks to the delicate and diminutive hawthornes, from bald cypress with their knees poking up from the swamps to the coppery-colored gumbo limbo found in tropical hammocks of the Everglades and Keys, from the sabal palm found all over the state to the rare and endangered yew found only along the banks of the Apalachicola River in northern Florida. Florida, unique among the states, has both tropical and temperate forests. The early Florida visitor was awed by miles of unending pine flatwoods. Most modern Florida visitors are amazed by the lush tropical trees planted in cities, suburbs, and public gardens. This book covers both natives and exotics and includes suggested field sites for observing the species described. Divided into two sections, this book serves as both a reference and a field guide. Both sections help the reader answer the question “What tree is that?" by focusing on the families of Florida's trees. The line drawings show a combination of typical leaves, fruits, and flowers, and while accurate in detail, capture an overall impression, so helpful when trying to identify a species in the field. The color photos, all taken in Florida, are useful where color is important in identification. The first edition was very popular with both professionals and laypeople alike—it was heralded as accurate, comprehensive, and organized and written in an easy-to-understand way. This edition will be even more useful, as it adds about 140 more tree accounts for a total of more than 480 species. There are almost 600 color photos and many drawings and range maps. And now included is a key to tree families that will help with field identification.
Set includes revised editions of some issues.
