Often growing far above the ground, "air plants" (or epiphytes) defy many of our common perceptions about plants. The majority use their roots only for attachment in the crowns of larger, usually woody plants-or to objects such as rocks and buildings-and derive moisture and nutrients from the atmosphere and by collecting falling debris. Only the mistletoes are true parasites. Epiphytes are not anomalies and there are approximately 28,000 species-about 10 percent of the higher or vascular plants-that grow this way. Many popular houseplants, including numerous aroids, bromeliads, ferns, and orchids, rank among the most familiar examples. In Air Plants, David H. Benzing takes a reader on a tour of the many taxonomic groups to which the epiphytes belong and explains in nontechnical language the anatomical and physiological adaptations that allow these plants to conserve water, thrive without the benefit of soil, and engage in unusual relationships with animals such as frogs and ants. Benzing's comprehensive account covers topics including ecology, evolution, photosynthesis and water relations, mineral nutrition, reproduction, and the nature of the forest canopy as habitat for the free-living and parasitic epiphytes. It also pays special attention to important phenomena such as adaptive trade-offs and leaf economics. Drawing on the author's deep experience with epiphytes and the latest scientific research, this book is accessible to readers unfamiliar with technical botany; it features a lavish illustration program, references, a glossary, and tables.

The Galápagos are home to a wide-ranging assortment of unusual plants and animals. The islands became famous as the site of Charles Darwin's research leading to his theory of evolution by natural selection, and their magnificent flora and fauna continue to draw visitors from around the world. Based on the author's sixteen years of fieldwork and featuring his exceptional photography, Flowering Plants of the Galápagos is the first accessible, in-depth yet compact guide to the plant life of the area. An invaluable resource for tourists, natural history enthusiasts, and professionals, the book:* introduces the botanical history of the islands and their varied ecological zones* allows easy identification of 436 flowering plants (77 families, 192 genera, and 390 species)* covers endemic plants found exclusively on the islands; native plants, which grow on the Galápagos and elsewhere; and exotic plants present as a result of human actions* offers thorough accounts of the plants which give the scientific, common, and family names; range; islands inhabited; habitat; description; and additional notes of interest* is richly illustrated with 266 color photographs of flowering plants and 117 of plant pollinators, vegetation zones, non-flowering plants, and the islands themselves* organizes species by form, leaf arrangement, and flower color and includes descriptive plant drawings to aid in identification * provides a map of the Galápagos and a list of plants likely to be seen at popular tourist sites

This book critically reviews advances in our understanding of the biology of vascular epiphytes since Andreas Schimper’s 1888 seminal work. It addresses all aspects of their biology, from anatomy and physiology to ecology and evolution, in the context of general biological principles. By comparing epiphytes with non-epiphytes throughout, it offers a valuable resource for researchers in plant sciences and related disciplines. A particular strength is the identification of research areas that have not received the attention they deserve, with conservation being a case in point. Scientists have tended to study pristine systems, but global developments call for information on epiphytes in human-disturbed systems and the response of epiphytes to global climate change.

Epiphytes (plants which grow on other plants, not parasitically but for support), comprise more than one-third of the total vascular flora in some tropical forests. Growing within tropical forest canopies, epiphytes are subject to severe environmental constraints, and their diverse adaptations make them a rich resource for studies of water balance, nutrition, reproduction and evolution. This book synthesizes the body of information from research on epiphytes and their relations with other tropical biota, and provides a comprehensive overview of basic functions, life history, evolution, and the place of epiphytes in complex tropical communities. Tropical ecologists and zoologists as well as plant scientists will find this volume a useful guide to research on the twenty-five thousand species of epiphytes which root in the crowns of tropical trees.

To respond to the increasing need to feed the world's population as well as an ever greater demand for a balanced and healthy diet there is a continuing need to produce improved new cultivars or varieties of plants, particularly crop plants. The strategies used to produce these are increasingly based on our knowledge of relevant science, particularly genetics, but involves a multidisciplinary understanding that optimizes the approaches taken. Principles of Plant Genetics and Breeding, 2nd Edition introduces both classical and molecular tools for plant breeding. Topics such as biotechnology in plant breeding, intellectual property, risks, emerging concepts (decentralized breeding, organic breeding), and more are addressed in the new, updated edition of this text. Industry highlight boxes are included throughout the text to contextualize the information given through the professional experiences of plant breeders. The final chapters provide a useful reference on breeding the largest and most common crops. Up-to-date edition of this bestselling book incorporating the most recent technologies in the field Combines both theory and practice in modern plant breeding Updated industry highlights help to illustrate the concepts outlined in the text Self assessment questions at the end of each chapter aid student learning Accompanying website with artwork from the book available to instructors

In The Petroleum Triangle, Steve A. Yetiv tells the interconnected story of oil, globalization, and terrorism. Yetiv asks how Al-Qaeda, a small band of terrorists, became such a real and perceived threat to American and global security, a threat viewed as profound enough to motivate the strongest power in world history to undertake extraordinary actions, including two very costly wars. Yetiv argues that Middle East oil and globalization have combined to augment the real and perceived threat of transnational terrorism. Globalization has allowed terrorists to do things that otherwise would be more difficult and costly: exploit technology, generate fear beyond their capabilities, target vulnerable economic and political nodes, and capitalize on socio-economic dislocation. Meanwhile, Middle East oil has fueled terrorism by helping to bolster oil-rich regimes that terrorists hate, to fund the terrorist infrastructure, and to generate anti-American and anti-Western sentiments about American support for oil-rich regimes and perceived Western designs on Middle East oil. Together, Middle East oil and globalization have combined in various ways to help create Al-Qaeda's real and perceived threat, and that of its affiliates and offshoots. The combined effect has shaped important contours of the Petroleum Triangle and of world affairs. A sweeping analysis of contemporary world politics and American foreign and military policy, The Petroleum Triangle convincingly argues that it is critical to understand the connections among oil, globalization, and terrorism if we seek to comprehend modern global politics. What happens within the Petroleum Triangle will help determine if the death of Osama bin Laden will ultimately cripple Al-Qaeda and its affiliates or be yet another milestone in an ongoing age of terrorism.

In his lectures my teacher Karl Mägdefrau used to say that one only becomes a real plant scientist when one enters a tropical rainforest. For me this initiation occurred in 1969 in northern Queensland, Australia, and was associated with the greatest excitement. On another level it received confirmation when I set out in 1983 together with some friends and colleagues for the first detailed ecophysiological studies of epiphytes in the wet tropics in situ in the island of Trinidad and later for similar work in Venezuela. This then promoted the idea of organizing a special symposium on "The evolution and ecophysiology of vascular plants as epiphytes" during the XIV International Botanical Congress in luly 1987 in Berlin, and to ask some of the speakers to produce chapters for a small monograph on the interesting ecologically defined group of plants "epiphytes" as presented in this volume of "Ecological Studies". The enthusiasm of the participants of the symposium giving reports and adding to the discussion was most stimulating, and it appears that epiphytes might gain well-deserved, wider consideration in the future. The cooperation with the authors of this book was very pleasant and I appreciated the new contacts established with adepts of the "epiphyte community". The chapters were organized and arranged covering first more gen eral aspects with setting the scene in Chapter 1, the evolution of epi phytism in Chapter 2 and the role of CO -concentrating mechanisms in 2 Chapter 3.
