The tobacco plant synthesizes nicotine to protect itself from herbivores. The female moth broadcasts sex pheromones to attract a mate, while a soldier ant deploys an alarm pheromone to call for help. The carbon dioxide on a mammal's breath beckons hungry ticks and mosquitoes, while a flower's fragrance speaks to the honey bee. Indeed, much of the communication that occurs within and between various species of organisms is done not by sight, sound, or touch, but with chemicals. From mating to parenting, foraging to self-defense, plant and animal activities are accomplished largely by the secretion or exchange of organic chemicals. The fascinating and fast-developing science that encompasses these diverse phenomena is introduced here, by William Agosta, in a series of remarkable stories absolutely accessible to the general reader yet revelatory to chemists and biologists. Among Agosta's characters are the organisms that steal, counterfeit, or interpret the chemical signals of other species for their own ends. We learn of seeds that mimic ant odors to facilitate their own dispersion and flies that follow the scent of truffles to lay their eggs. We read about pit vipers that react in terror when their flicking tongues detect a king snake, and slave-making ants incapable of finding their own food. And we meet ice-age people who ate birch fungus to relieve whipworms and early human hunters who used the urine of wolves to maneuver deer to favorable sites. Agosta also chronicles the rapid development of the applied science that makes use of chemical ecology. As researchers deepen our understanding of the biological world, they are making economically significant discoveries (such as enzymes that remain stable in extreme heat), finding ways to reduce our reliance on manufactured pesticides, identifying new uses for traditional medicines, and developing sophisticated new pharmaceuticals effective in treating malaria and several cancers. On the horizon are antiviral agents derived from the chemical defenses of marine species. From the exploits of flies to the high-stakes effort to cure human disease, Agosta's tour of chemical ecology grants any reader entrance to the invisible realm where chemistry determines life and death.

A Selection of the Discovery Channel Book Club In sixteen stories Steve Daubert pulls the reader into the mystery and immediacy of ecological processes spanning a range from microscopic to tectonic, from microscopic to cosmic forces. Each tale brings the reader into the moment to witness an episode of survival in the wild first-hand. The material is presented on a level of intimacy and detail not usually encountered in other styles of natural history writing. These creative non-fiction stories provide not just a bird's eye view (though that's true for the owls, warblers, condors, and hummingbirds in the book), but a wasp's eye view, a mouse's, a sea turtle's, a squid's. Sometimes the focus is as small as the detritus on the forest floor, or a single beat of the wing of a gull. Other stories range across evolutionary time. From whales and dinosaurs to creatures invisible to the naked eye, author and illustrator bring to life the dynamic interplay of living, evolving creatures and the natural forces that have shaped their worlds. The book includes chapter notes that document the scientific basis for each story and describe the controversies still surrounding some of them -- a splendid resource for families to read and share.

In the nearly 10 years since the publication of the bestselling first edition of Introduction to Green Chemistry, interest in green chemistry and clean processes has grown so much that topics, such as fluorous biphasic catalysis, metal organic frameworks, and process intensification, barely mentioned in the first edition, have become major areas of research. In addition, government funding has ramped up the development of fuel cells and biofuels. It reflects the evolving focus from pollution remediation to pollution prevention. Copiously illustrated with over 800 figures, this second edition provides an update from the frontiers of the field. New and expanded research topics: Metal-organic frameworks Solid acids for alkylation of isobutene by butanes Carbon molecular sieves Mixed micro- and mesoporous solids Organocatalysis Process intensification and gas phase enzymatic reactions Hydrogen storage for fuel cells Reactive distillation Catalysts in action on an atomic scale Updated and expanded current events topics: Industry resistance to inherently safer chemistry Nuclear power Removal of mercury from vaccines Removal of mercury and lead from primary explosives Biofuels Uses for surplus glycerol New hard materials to reduce wear Electronic waste Smart growth The book covers traditional green chemistry topics, including catalysis, benign solvents, and alternative feedstocks. It also discusses relevant but less frequently covered topics with chapters such as Chemistry of Longer Wear and Population and the Environment. This coverage highlights the importance of chemistry to everyday life and demonstrates the benefits the expanded exploitation of green chemistry can have for society.

The main purpose of the book is to provide insight into an area that humans often take for granted. There are wonderful and exciting stories of organisms using chemical signals as a basis of a sophisticated communication system. In many instances, chemical signals can provide more detailed and accurate information than any other mode of communication, yet this world is hidden from us because of our focus on visual and auditory signals.​ Although we have a diversity of senses available to us, humans are primarily auditory and visual animals. These stimuli are sent to the more cognitive areas of our brain where they are immediately processed for information. We use sounds to communicate and music to excite or soothe us. Our vision provides us with communication, entertainment, and information about our world. Even though our world is dominated by other stimulus energies, we have chosen, in an evolutionary sense, either auditory or visual signals to carry our most important information. This is not the case for most other organisms. Chemical signals, mediated through the sense of smell and taste, are typically more important and are used more often than other sensory signals. The world of communication using chemicals is an alien world for us. We are unaware of how important chemical signals are to other organisms and we often overlook the influence of chemical signals in our own life. Part of this naïveté about chemical signals is due to our cultural focus on visual and auditory signals, but a larger part of our collective ignorance is the lack of information about chemical communication in both popular and scientific writings. The popular press and popular writings virtually ignore the chemical senses, especially in regard to their role or influence for humans and our human culture. Academic books and textbooks are no better.

During the past decade, the study of the chemical structures used by insects has advanced from a subject that could be reviewed in a single volume to a vastly more advanced level. This important new volume brings together a focused group of reviews that offer perspective on the most interesting advances in insect chemical ecology. Chemical Ecology of Insects 2 brings together an internationally respected group of experts covering such topics as chemoreception and integration, orientation mechanisms, plant-insect interactions and insect-insect interactions. An important benefit of these reviews lies in the identification of the boundaries of our current knowledge and the most profitable areas in which we should expect these areas to develop. This important work will appeal to entomologists and ecologists working directly with insects. In addition, plant scientists interested in the interaction of plants and insects will find much valuable information. The book is intended to benefit both field and laboratory researchers as well as advanced students.

In their sometimes fierce, often mysterious lives, many plants and animals rely on the transmission and reception of chemicals to attack, defend, eat, and avoid being eaten. In this exciting book, Agosta tells the story of the surprising interplay between the hunters and the hunted in the gardens, fields, and forests of the world.
