Why Elephants Cry is a fascinating frolic through the literature and evidence surrounding the use of unusual behavior of animals to measure and predict the environment. The role of animals, from the smallest ant to the biggest elephant, as predictors of environmental changes is framed around the climate crisis, which highlights the increasingly important part that animals will have to play in the future. Renowned biologist Professor John T. Hancock collects anecdotal stories and myths along with scientific evidence, demonstrating that observation of animals can be of tangible use. He looks at the measurement of the air temperature using ants, crickets and snakes, and goes on to assess the evidence that the observation of a wide range of animals can predict the weather or the imminent eruption of volcanoes and earthquakes. Evidence of animals being able to predict lunar and solar events, such as lunar cycles and the Northern Lights, is also considered. This is the only time that all this literature has been brought together in one place, a fascinating reference for anybody interested in animals and the environment. The book is also an ideal supplementary textbook for students studying animal behaviour.

It's alive! It's alive! (Thanks to biochemistry, that is.) Biochemistry is the science of the chemical processes that allow for…well…life. If it moves, breathes, eats, or sleeps, biochemistry can probably explain how. So, it stands to reason that the fundamentals of biochemistry can get a little complicated. In Biochemistry For Dummies, you'll explore the carbons, proteins, and cellular systems that make up the biochemical processes that create and sustain life of all kinds. Perfect for students majoring in biology, chemistry, pre-med, health-services, and other science-related fields, this book tracks a typical college-level biochemistry class. It simplifies and clarifies the subject with easy-to-follow diagrams and real-world examples.

Phytochemicals from medicinal plants are receiving ever greater attention in the scientific literature, in medicine, and in the world economy in general. For example, the global value of plant-derived pharmaceuticals will reach $500 billion in the year 2000 in the OECD countries. In the developing countries, over-the-counter remedies and'ethical phytomedicines,'which are standardized toxicologically and clinically defined crude drugs, are seen as a promising low­ cost alternatives in primary health care. The field also has benefited greatly in recent years from the interaction of the study of traditional ethnobotanical knowledge and the application of modem phytochemical analysis and biological activity studies to medicinal plants. The papers on this topic assembled in the present volume were presented at the annual meeting of the Phytochemical Society of North America, held in Mexico City, August 15-19, 1994. This meeting location was chosen at the time of entry of Mexico into the North American Free Trade Agreement as another way to celebrate the closer ties between Mexico, the United States, and Canada. The meeting site was the historic Calinda Geneve Hotel in Mexico City, a most appropriate site to host a group of phytochemists, since it was the address of Russel Marker. Marker lived at the hotel, and his famous papers on steroidal saponins from Dioscorea composita, which launched the birth control pill, bear the address of the hotel.

Diversity within and among living organisms is both a biological impera­ tive and a biological conundrum. Phenotypic and genotypic diversity is the critical currency ofecological interactions and the evolution of life. Thus, it is not unexpected to find vast phytochemical diversity among plants. However, among the most compelling questions which arise among those interested in ecological phytochemistry is the extent, nature, and reasons for the diversity of chemieals in plants. The idea that natural products (secondary metabolites) are accidents of metabolism and have no biological function is an old one which has resurfaced recently under a new term'redundancy.'Redundancy in the broader sense can be viewed as duplication of effort. The co-occurrence of several classes of phytochemieals in a given plant may be redundancy. Is there unnecessary duplication of chemical defense systems and ifso, why? What selective forces have produced this result? On the other hand, why does the same compound often have multiple functions? At a symposium of the Phytochemical Society of North America held in August 1995, in Sault Ste. Marie, Ontario, Canada, the topic'Phytochernical Redundancy in Ecological Interactions'was discussed. The chapters in this volume are based on that symposium. They both stimulate thought and provide some working hypotheses for future research. It is being increasingly recognized that functional diversity and multiplicity of function of natural products is the norm rather than the exception.

Throughout the tropics, vast areas of rainforest and other biologically diverse lands are being cleared for agricultural or related uses. Rainforests, the most dramatic example of tropical habitat destrucLion, are estimated to be disappearing at the rate of up to 20.4 million hectares per year world-wide (based on FAO estimates; see World Resources 1990-1991, Oxford University Press)­ more than 2% of the total area covered by tropical rainforests per year. Destruction of these complex habitats results in the irreversible loss of both plant and animal diversity, and dramatically illustraLes the need to investigate these threatened species for potentially useful constituents-especially the identification and characterization of novel biologically-active phytochemicals with pharmacologiical and/or pesticidal properties. This volume is based on papers presented by invited speakers at an international symposium entitled'Phytochemical POlential of Tropical Plants: held in conjunction with the second joint meeting of the Phytochemical nd Societies of Europe and North America, as well as the 32 annual meeting of the latter society. The meeting was held at the Deauville Hotel, Miami Beach, Florida, USA from August 8-12,1992. One hundred and twenty-five participants from more than 20 countries attended this meeting.

Phytochemists are aware that their focus of interest is receiving attention from a wider segment of society and from a greater diversity of disciplines within the scientific community than ever before. Nonetheless, they were bemused to learn three years ago that'until recently scientists didn't even know phytochemi­ cals existed'(Newsweek, April 24, 1994). Changing public perception of the positive contributions of phytochemicals to human well-being has foundations in scientific advances. With popular reports emphasizing the important implica­ tions of phytochemicals in the daily lives of people, there is a pressing need for those working in this area to explain their diverse scientific activities to the public. Chemicals from plant foods are linked through epidemiological and ex­ perimental studies with reduced incidence of chronic degenerative diseases. Phytomedicines, standardized according to particular constituents, are making increasing contributions to health care. Naturally occurring constituents of plants are recognized as fundamental to the appeal, quality, and marketability of food products. In light of such developments, perceptions by phytochemists of their own discipline and its applications are expanding. Until recently, food phyto­ chemistry largely implied food toxicants. Food plants were familiar, but seldom the source of novel economically important compounds. Increasingly sophisti­ cated methods of analysis, however, have opened new opportunities for under­ standing the nature and functions offood constituents, and for manipulating them to improve the quality, acceptability, and value of food products.

6 Ions can pass through a single membrane channel at a rate of 10 ions/second. Over the last decade the ability to measure ion flux so precisely and to document the opening and closing of individual ion channels has provided a powerful tool to those working on smooth muscle physiology and vascular reactivity. The use of potassium channel blockers by Tom Lloyd in the 1960s and calcium channel blockers by Ivan McMurtry in the 1970s indicated the importance of ion flux in regulating pulmonary vascular tone. Recent advances in technology. principally the patch-clamp technique and fluorescent ion-sensitive dyes. now permit a more detailed description of physiologic mechanisms. This volume arises from the Sixth Grover Conference on the Pulmonary Circulation. a NATO Advanced Research Workshop. held in Colorado in October 1992. A group of international sCientists who are leaders in the field of ion flux focused their attention on the problems of the pulmonary vasculature. The chapters in this book describe the present state of knowledge of the movement and storage of ions in vascular endothelial and smooth muscle cells. Those who are not familiar with the techniques of patch clamping and calcium imaging will find an introduction to these methods in the chapters by Leblanc and Wan and Archer et al. The role of potassium channels in oxygen sensing illustrates the rapid progress which the study of ion currents has made possible.
