Book Description
Intraspecific communication involves the activation of chemoreceptors and subsequent activation of different central areas that coordinate the responses of the entire organism—ranging from behavioral modification to modulation of hormones release. Animals emit intraspecific chemical signals, often referred to as pheromones, to advertise their presence to members of the same species and to regulate interactions aimed at establishing and regulating social and reproductive bonds. In the last two decades, scientists have developed a greater understanding of the neural processing of these chemical signals. Neurobiology of Chemical Communication explores the role of the chemical senses in mediating intraspecific communication. Providing an up-to-date outline of the most recent advances in the field, it presents data from laboratory and wild species, ranging from invertebrates to vertebrates, from insects to humans. The book examines the structure, anatomy, electrophysiology, and molecular biology of pheromones. It discusses how chemical signals work on different mammalian and non-mammalian species and includes chapters on insects, Drosophila, honey bees, amphibians, mice, tigers, and cattle. It also explores the controversial topic of human pheromones. An essential reference for students and researchers in the field of pheromones, this is also an ideal resource for those working on behavioral phenotyping of animal models and persons interested in the biology/ecology of wild and domestic species.

Book Description
The crustaceans are ecologically and economically important organisms. They constitute one of the dominant invertebrate groups on earth, particularly within the aquatic realm. Crustaceans include some of the preferred scientific model organism, profitable aquaculture specimen, but also invasive nuisance species threatening native animal communities throughout the world. Chemoreception is the most important sensory modality of crustaceans, acquiring important information about their environment and picking up the chemical signals that mediate communication with conspecifics. Significant advances have been made in our understanding of crustacean chemical communication during the past decade. This includes knowledge about the identity, production, transfer, reception and behavioral function of chemical signals in selected crustacean groups. While it is well known that chemical communication is an integral part of the behavioral ecology of most living organisms, the intricate ways in which organisms allocate chemicals in communication remains enigmatic. How does the environment influence the evolution of chemical communication? What are the environmental cues that induce production or release of chemicals? How do individuals economize production and utilization of chemicals? What is the importance of molecule specificity or mix of a molecule cocktail in chemical communication? What is the role of chemical cues in multimodal communication? How does the ontogenetic stage, the sex or the physiological status of an individual affect its reaction to chemical cues? Many of these questions still represent important challenges to biologists.

Book Description
A wounded minnow attempts to rejoin its school and the other minnows scatter in panic; a single beetle finds a pine tree to its liking and soon thousands of beetles swarm that tree and others in the vicinity; a male Syrian golden hamster is drawn along an invisible trail to a burrow where a female hamster awaits him, ready for mating. These animals are responding to received communications, but, as in countless other occurrences in nature, the language is not auditory or visual--it is chemical. Unlike humans, who gather information largely through sight and sound, most living creatures rely heavily on chemical compounds from other organisms for their basic knowledge of the world. Among the various types of these compounds are the chemical signals exchanged between members of the same species that govern social interactions crucial to survival. These signals are called pheromones (from the Greek "pherein"--to carry--and "hormon"--exciting) and they are used to send warnings, establish territorial boundaries, provoke aggression, control sexual behavior, and locate food. In this volume, organic chemist William C. Agosta explores the chemistry of pheromones and the mechanisms by which they orchestrate animal behavior. Professor Agosta details the intricate process of identifying pheromones: first establishing that some behavior in animals is chemically driven, then isolating pheromones and determining the active components within these sometimes highly complex mixtures. He also demonstrates the value of this growing body of knowledge to our understanding of evolution, ecology, human behavior, and agricultural production. The result is a fascinating look at a research area that bringstogether investigators, information, technologies, and procedures from the fields of biology, chemistry, and behavioral science. Chemical Communication spans the entire spectrum of life, from simple organisms, such as water molds and brown algae, to insects, birds, fish, reptiles, mammals, and in a provocative final chapter, human beings. Along the way, Dr. Agosta provides dozens of captivating examples of pheromones in action: certain male red-sided garter snakes, which increase their chances of mating successfully by "impersonating" a female, thus distracting rivals; or the bolas spiders, which capture male moths by hitting them with an adhesive ball on a string after emitting a female moth pheromone that lures the males within range. The book also includes important evidence that pheromones alter physiology as well as behavior. For example, young female mice reach maturity at an accelerated pace after constant exposure to adult male mice.

Book Description
In the time since the second edition of The ACS Style Guide was published, the rapid growth of electronic communication has dramatically changed the scientific, technical, and medical (STM) publication world. This dynamic mode of dissemination is enabling scientists, engineers, and medicalpractitioners all over the world to obtain and transmit information quickly and easily. An essential constant in this changing environment is the requirement that information remain accurate, clear, unambiguous, and ethically sound.This extensive revision of The ACS Style Guide thoroughly examines electronic tools now available to assist STM writers in preparing manuscripts and communicating with publishers. Valuable updates include discussions of markup languages, citation of electronic sources, online submission ofmanuscripts, and preparation of figures, tables, and structures. In keeping current with the changing environment, this edition also contains references to many resources on the internet.With this wealth of new information, The ACS Style Guide's Third Edition continues its long tradition of providing invaluable insight on ethics in scientific communication, the editorial process, copyright, conventions in chemistry, grammar, punctuation, spelling, and writing style for any STMauthor, reviewer, or editor. The Third Edition is the definitive source for all information needed to write, review, submit, and edit scholarly and scientific manuscripts.

Book Description
One major goal of post-genomic biology is to understand the function of genes. Many gene functions are comprehensible only within the context of chemical communication, and this symposium seeks to highlight emerging research on genomics and chemical communication and catalyze further development of this highly productive interface. Many of the most abundantly represented genes in the genomes characterized to date encode proteins mediating interactions among organisms, including odorant receptors and binding proteins, enzymes involved in biosynthesis of pheromones and toxins, and enzymes catalyzing the detoxification of defense compounds. Determining the molecular underpinnings of the component elements of chemical communication systems in all of their forms has the potential to explain a vast array of ecological, physiological, and evolutionary phenomena; by the same token, ecologists who elucidate the environmental challenges faced by the organisms are uniquely well-equipped to characterize natural ligands for receptors and substrates for enzymes. Thus, partnerships between genome biologists and chemical ecologists will likely be extremely synergistic. To date, these groups have rarely had opportunities to interact within a single forum. Such interactions are vital given the considerable practical benefits potentially stemming from these studies, including the development of biorational products for agricultural and forest pest management, for disease treatment, and for improving the quality of ecosystem health.
