This book looks at how three kinds of strongly electric fishes literally became "electrical," and how they helped to change the sciences and medicine. These fishes are the flat torpedo rays common to the Mediterranean, the electric catfishes of Africa, and an "eel" from South America. The discovery of the electrical nature of these fishes in the second half of the 18th century was the starting point of the two fundamental advances in the sciences: on the physiological side, the demonstration that nerve conduction and muscle excitation are electrical phenomena, and on the physical side, the invention of the electric battery. Starting with catfish tomb drawings from Ancient Egypt and colorful descriptions of torpedoes from the Classical Era, the authors show how these fishes were both fascinating and mysterious to the ancients. After all, not only could they produce torpor and temporary numbness when touched, they could stun through intermediaries, such as wet nets and spears.
Various explanations were given for these remarkable actions in ancient times, including the idea that they might release some sort of cold venom. Through the Renaissance, they also tended to be associated with occult and magical qualities. During the 1600s, natural philosophers speculated that rapid movements of specialized muscles could account for their actions. This idea was widely accepted until the 1750s, when the possibility that their shocks might be electrical began to be discussed.
Showing how researchers set forth to provide support for fish electricity is a major focus of this book. Here the authors transport us into the jungles of South America and later show how some live eels were transported to London, where John Walsh demonstrated in1776 that they can actually spark.
Subsequent chapters deal with further evidence for specialized fish electricity and how electric fishes helped to change ideas about even our own physiology. The authors also show how these fish remained a part of medicine, and how Volta modeled his revolutionary "pile" or electric battery on their anatomy.
From beginning to end, this drama is firmly anchored in the philosophy and science of the day. Moreover, with biographical information about the key players, readers can fully appreciate what they were thinking as they tried to understand one of Nature's greatest puzzles - a mystery that would transform nerve and muscle physiology in ways that earlier generations could not have anticipated. Although a scholarly volume, the book's style is generally narrative and, with its hundreds of magnificent illustrations, it should appeal to a large audience.

A valuable new reference on insect behavior, this exceptional new text delves into the primary sensory communication system used by most insects -- their sense of smell. This important text covers how insects produce pheromones and how they detect pheromones and plant volatiles. Since insects rely on pheromone detection for both feeding and breeding, a better understanding of insect olfaction and pheromone biosynthesis could help curb the behavior of pests without the use of harmful pesticides and even help to reduce the socio-economic impacts associated to human-insect interactions.
* Covers biochemistry and molecular biology of insect pheromone production
* Explains pheromone production in moths, beetles, flies, and social insects
* Describes pheromone and plant volatile reception

Fungal growths affect both human and animal well-being. Many natural pathogens of laboratory animals alter host physiology, rendering the host unsuitable for experimental uses. While the number and prevalence of few pathogens have declined considerably, many still turn up in laboratory animals and represent unwanted variables in research. Investigators using laboratory animals in biomedical experimentation should be aware of the profound effects that many of these agents can have on research. What does the future hold regarding the natural pathogens of laboratory animals? The selection of an animal model must carefully address issues of the type of human disease to mimic, the parameters to follow, and the collection of the appropriate data to answer those questions being asked. Overall, animal models of fungal infection will continue to deepen our understanding of how these infections occur. This book provides a valuable source of information to biological and biomedical scientists and to clinical and doctoral researchers working in the area of fungal infections and diseases of laboratory animal species.

This book offers the first comprehensive review of parasitic Crustacea, which are among the most successful and diverse parasites. Starting with an introductory chapter, followed by an historic overview and topic-specific chapters, each presenting a different aspect of parasitic crustacean biology, it enables readers to gain a better understanding of how these parasites function and allows direct comparisons between the different parasitic crustacean groups. The authors also discuss, in depth, the adaptations and interactions that have made parasitic Crustacea as successful as they are today, covering topics ranging from the history of their discovery, their biodiversity, phylogeny, evolution and life strategies to their role as vectors, or hosts of other organisms, and their significance in ecological processes. Consisting of ten chapters from leading international experts in the field, this volume offers a one-stop resource for all researchers, lecturers, students and practitioners.

Exploring Animal Behavior in Laboratory and Field is designed to provide a variety of exercises that engage students actively in all phases of scientific investigation, from formulating research questions through interpreting and presenting final results. It attempts to share the collective teaching expertise and experience of members of the Animal Behavior Society with all who are willing to benefit from their wisdom. Four types of exercises are presented: (1) traditional exercises in which students follow a pre-determined protocol to test particular hypotheses explicitly stated in the exercise, (2) traditional exercises that can easily be adapted to inquiry-based approaches, (3) combined pedagogy exercises that involve both traditional and inquiry approaches, and (4) inquiry exercises in which students first brainstorm to generate their own hypotheses, then design their own experiements to test their hypotheses.
* Supports a range of pedagogical styles and texts in animal behavior with active learning experiences that engage students
* Students and instructors benefit from knowledge and experience of members of the Animal Behavior Society
* Flexibility of design enables students and instrucotrs to tailor the exercises to their needs
* Can be used to support lab courses that are completely inquiry based as well as independent student research projects in animal behavior
* Consideration of animal care guidelines provides an excellent way to address and discuss concerns about the use of animals in teaching and research
* Emphasizes the hypothetico-deductive approach that students have difficulty understanding and implementing
* Supporting materials make additional required texts unnecessary and link study design considerations with real studies

By far, the most widely used subjects in psychological and biological research today are rodents. Although rats and mice comprise the largest group of animals used in research, there are over 2,000 species and 27 families of rodents, living all over the world (except Antarctica) and thriving in many different habitat types. The vast environmental diversity that rodents face has led to numerous adaptations for communication, including vocalizing and hearing in both the sonic and ultrasonic ranges, effectively communicating in the open air and underground, and using vocalizations for coordinating sexual behavior, for mother-pup interactions, and for signaling an alarming situation to the group. Some rodent species have even developed foot drumming behaviors for communication. Comparative studies from around the globe, using both field and laboratory methodologies, reveal the vast differences in acoustic communication behavior across many rodent species. Some rodents are amenable to training and have been domesticated and bred purely for research purposes. Since the early 1900s, rats and mice have been indispensable to research programs around the world. Thus, much of what we know about hearing and vocalizations in rodents come from these two species tested in the laboratory. The sequencing of the mouse genome in 2002, followed by the rat genome in 2004, only increased the utility of these animals as research subjects since genetically engineered strains mimicking human diseases and disorders could be developed more easily. In the laboratory, rats and mice are used as models for human communication and hearing disorders and are involved in studies on hearing loss and prevention, hormones, and auditory plasticity, to name a few. We know that certain strains of mice retain hearing better than others throughout their lifespan, and about the genes involved in those differences. We know about the effects of noise, hormones, sex, aging, and circadian rhythms on hearing in mice and other rodents. We also know about normal hearing in many families of rodents, including the perception of simple and complex stimuli and the anatomy and physiology of hearing and sound localization. The importance of acoustic communication to these animals, as well as the significance of these mammals to biomedical research, are summarized in the chapters.

Australia's varied grasslands have suffered massive losses and changes since European settlement, and those changes continue under increasingly intensive human pressures for development and agricultural production. The values of native grasslands for conservation of endemic native biodiversity, both flora and fauna, have led to strong interests in the protection of remaining fragments, especially near urban centres, and documentation of the insects and other inhabitants of grasslands spanning tropical to cool temperate parts of the country. Attention to conservation of grassland insects in Australia is relatively recent, but it is increasingly apparent that grasslands harbour many localised and ecologically specialised endemic species. Their conservation necessarily advances from very incomplete documentation, and draws heavily on lessons from the far better-documented grasslands elsewhere, most notably in the northern hemisphere, and undertaken over far longer periods. From those cases, and the extensive background to grassland management to harmonise conservation with production and amenity values through honing use of processes such as grazing, mowing and fire, the needs and priorities for Australia can become clearer, together with needs for grassland restoration at a variety of scales. This book is a broad overview of conservation needs of grassland insects in Australia, drawing on the background provided elsewhere in the world on the responses to disturbances, and the ecological importance, of some key insect groups (notably Orthoptera, Hemiptera and Lepidoptera) to suggest how insect conservation in native, pastoral and urban grasslands may be advanced. The substantial references given for each chapter facilitate entry for non-entomologist grassland managers and stewards to appreciate the diversity and importance of Australia's grassland insects, their vulnerabilities to changes, and the possibilities for conserving them and the wider ecological roles in which they participate.

This book provides an up-to-date review of fasciolosis, a disease caused by Fasciola hepatica and Fasciola gigantica, including its biology, transmission, epidemiology, host distribution, economic impact, and novel approaches for its diagnosis, treatment and prevention. It first offers a brief overview of the history of the disease, the genetic diversity of the parasite and its distribution, and the ecology of the vector snail, which belongs to the Lymnaeidae/Planorbidae family. It also examines the current strategies and novel approaches for controlling the parasite, diagnosing infections and vaccine development. Importantly, it highlights issues relating to the control of fasciolosis, including drug resistance, lack of effective diagnostics, and the parasite's long-term survival strategies based on regulation and modulation of the host immune system. Lastly, it discusses the novel control snail vectors using bait formulations, and synergetic and phototherapy treatment with chlorophyllin, which does not kill the vector.

Our understanding of the basic biology of owls is poor compared to that of other bird species. The Little Owl, Athene noctua, has become one of the best models for biological and conservation research, due to its commonness and the fact that it occupies nest-boxes very easily. In this unique book the authors synthesise the substantial literature, and detail current information regarding the Little Owl. They discuss its wide-ranging ecology, genetics and subspecies and population status by country. In addition, they outline a strategy and monitoring program for its conservation. The book features an outstanding bibliography of literature on the Little Owl, listing publications dated from 1769 to 2007, in many languages, including Russian, English, French, German, Spanish, Portuguese, Italian and Dutch. Whilst being an invaluable resource for academic researchers, its straightforward style holds undoubted appeal for amateurs and enthusiasts.

Whooping Cranes: Biology and Conservation covers one of the most endangered birds in North America, and the subject of intense research and highly visible conservation activity. The volume summarizes current biological information on Whooping Cranes and provides the basis for future research necessary for conservation of this species. This edited volume concentrates on work completed in the past 20 years in the areas of population biology, behavior and social structure, habitat use, disease and health, captive breeding, and Whooping Crane conservation. Much of the information presented comes from the study and management of remnant and reintroduced populations of Whooping Cranes in the field; some information is from experimentation and breeding of captive Whooping Cranes. Whooping Cranes: Biology and Conservation seeks to inform and galvanize action dedicated to meeting the challenges faced by Whooping Crane managers and conservationists. Thus, it describes one model of endangered species conservation and restoration that will interest a wide audience: professionals that work on cranes; researchers in the fields of small population biology, endangered species, and avian ecology; wildlife veterinarians and those involved in avian husbandry; administrators of management agencies or conservation organizations; conservationists in other fields; teachers of conservation biology or ornithology and their students; and the educated general public.
