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.

This book, first published in 2005, addresses food-mediated interactions, focusing on how plants employ foods to recruit arthropod 'bodyguards' as a protection against herbivores.

Book Description
In this update to the very popular first edition of the same name, skilled science popularizer Eric Grace helps readers understand what biotechnology is and what implications it holds for all of us. Following on the heels of the success of the first edition, this thoroughly updated version offers an in-depth and accessible review of the basics of biotechnology. Accomplished science communicator Eric Grace focuses on the ethical implications involved, the wide range of public opinions both at home and abroad, the role of the media in communicating a complicated science topic, and the formidable problems associated with patenting life itself. With an emphasis on medicine, agriculture, and the environment, Grace explores the promises and realities of biotechnology. He deals frankly with the fact that biotechnology is first and foremost a commercial activity, often driven by big business and directed by the bottom line. And as biotechnology is used more frequently in medical diagnosis and treatment, we are witness to significant setbacks and reversals, dimming hopes that were prevalent when the first edition was released. But we are also witness to the burgeoning use of the technology in forensic science where DNA analysis has become commonplace in solving crimes. Likewise, DNA analysis has been a boon to studies of human history and evolution, revealing ancient details originally thought lost to us. At the same time, new uses for genetically altered bacteria are being discovered that help us clean up the environment by breaking down or sequestering toxic chemicals. While the public remains concerned about biotechnology, there is increasing awareness of the potential benefits. This updated edition of Biotechnology Unzipped helps put the many issues in perspective and provides answers to the most important questions.

Book Description
This volume represents the published proceedings of an international conference on the Neurobiology and Evolution of the Mechanosensory Lateral Line System held August 31 to September 4, 1987, at the Center for Interdisciplinary Research at the University of Bielefeld, West Germany. The goal of this confer ence was to bring together researchers from all over the world to share informa tion about a major aquatic sensory system, the evolution and function of which have largely remained an enigma since the 18th century. The "lateral line" or "lateralis" system has been used as an umbrella term to describe what originally (without the aid of modern anatomical techniques) looked like a series of pits, grooves, and lines on the head and trunk of fishes and some amphibians. For at least the past 30 years, however, it has been recognized that the lateralis system comprises not one, but at least two functional classes of receptors: mechanoreceptors and electroreceptors. The relative ease with which the appropriate stimulus could be defined and measured for the electroreceptive class has resulted in an explosion of information on this submodality during the past 20 years. As a result, there is little ambiguity about the overall function of the electrosensory system, now generally regarded as an independent system in its own right. A similarly clear definition for the function of the mechanosensory lateralis system has not been as forthcoming.

Book Description
Researchers who study ancient human diets tend to focus on meat eating because the practice of butchery is very apparent in the archaeological record. In this volume, Julie Lesnik highlights a different food source, tracing evidence that humans and their hominin ancestors also consumed insects throughout the entire course of human evolution. Lesnik combines primatology, sociocultural anthropology, reproductive physiology, and paleoanthropology to examine the role of insects in the diets of hunter-gatherers and our nonhuman primate cousins. She posits that women would likely spend more time foraging for and eating insects than men, arguing that this pattern is important to note because women are too often ignored in reconstructions of ancient human behavior. Because of the abundance of insects and the low risk of acquiring them, insects were a reliable food source that mothers used to feed their families over the past five million years. Although they are consumed worldwide to this day, insects are not usually considered food in Western societies. Tying together ancient history with our modern lives, Lesnik points out that insects are highly nutritious and a very sustainable protein alternative. She believes that if we accept that edible insects are a part of the human legacy, we may have new conversations about what is good to eat—both in past diets and for the future of food.

Book Description
Olfaction and taste are of critical importance to insects and other animals, since vital behaviours, including mate, food and host seeking, as well as predator and toxin avoidance, are guided by chemosensory cues. Mate and habitat choice are to a large extent determined by chemical signals, and chemoreceptors contribute accordingly to pre-mating isolation barriers and speciation. In addition to fundamental physiological, ecological and evolutionary consideration, the knowledge of insect taste and especially olfaction is also of great importance to human economies, since it facilitates a more informed approach to the management of insect pests of agricultural crops and forests, and insect vectors of disease. Chemoreceptors, which bind to external chemical signals and then transform and send the sensory information to the brain, are at the core of the peripheral olfactory and gustatory system and have thus been the focus of recent research in chemical ecology. Specifically, emphasis has been placed on functional characterization of olfactory receptor genes, which are derived from three large gene families, namely the odorant receptors, gustatory receptors and ionotropic receptors. Spatial expression patterns of olfactory receptors in diverse chemosensory tissues provide information on divergent functions, with regards to ecologically relevant behaviours. On the other hand, characterization of olfactory receptor activation profiles, or “deorphanization”, provides complimentary data on the molecular range of receptivity to the fundamental unit of the olfactory sense. The aim of this Research Topic is to give an update on the breadth and depth of research currently in progress related to understanding the molecular mechanisms of insect chemoreception, with specific emphasis on the olfactory receptors.
