Humans have always been fascinated by marine life, from extremely small diatoms to the largest mammal that inhabits our planet, the blue whale. However, studying marine life in the ocean is an extremely difficult propo- tion because an ocean environment is not only vast but also opaque to most instruments and can be a hostile environment in which to perform expe- ments and research. The use of acoustics is one way to effectively study animal life in the ocean. Acoustic energy propagates in water more efficiently than almost any form of energy and can be utilized by animals for a variety of purposes and also by scientists interested in studying their behavior and natural history. However, underwater acoustics have traditionally been in the domain of physicists, engineers and mathematicians. Studying the natural history of animals is in the domain of biologists and physiologists. Und- standing behavior of animals has traditionally involved psychologists and zoologists. In short, marine bioacoustics is and will continue to be a diverse discipline involving investigators from a variety of backgrounds, with very different knowledge and skill sets. The inherent inter-disciplinary nature of marine bioacoustics presents a large challenge in writing a single text that would be meaningful to various investigators and students interested in this field. Yet we have embarked on this challenge to produce a volume that would be helpful to not only beginning investigators but to seasoned researchers.

This book offers an overview of some recent advances in the Computational Bioacoustics methods and technology. In the focus of discussion is the pursuit of scalability, which would facilitate real-world applications of different scope and purpose, such as wildlife monitoring, biodiversity assessment, pest population control, and monitoring the spread of disease transmitting mosquitoes. The various tasks of Computational Bioacoustics are described and a wide range of audio parameterization and recognition tasks related to the automated recognition of species and sound events is discussed. Many of the Computational Bioacoustics methods were originally developed for the needs of speech, audio, or image processing, and afterwards were adapted to the requirements of automated acoustic recognition of species, or were elaborated further to address the challenges of real-world operation in 24/7 mode. The interested reader is encouraged to follow the numerous references and links to web resources for further information and insights. This book is addressed to Software Engineers, IT experts, Computer Science researchers, Bioacousticians, and other practitioners concerned with the creation of new tools and services, aimed at enhancing the technological support to Computational Bioacoustics applications. STTM, Speech Technology and Text Mining in Medicine and Health Care This series demonstrates how the latest advances in speech technology and text mining positively affect patient healthcare and, in a much broader sense, public health at large. New developments in text mining methods have allowed health care providers to monitor a large population of patients at any time and from any location. Employing advanced summarization techniques, patient data can be readily extracted from extensive clinical documents in electronic health records and immediately made available to the physician. These same summarization techniques can also aid the healthcare provider in extracting from the large corpora of medical literature the relevant information for treating the patient. The series topics include the design and acceptance of speech-enabled robots that assist in the operating room, studies of signal processing and acoustic modeling for speech and communication disorders, advanced statistical speech enhancement methods for creating synthetic voice, and technologies for addressing speech and language impairments. Titles in the Series consist of both authored books and edited contributions. All authored books and contributed works are peer-reviewed. The Series is for speech scientists and speech engineers, machine learning experts, biomedical engineers, medical speech pathologists, linguists, and healthcare professionals

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.

Arguably biosonar is one of the ‘eye-opening’ discoveries about animal behavior and the auditory systems of echolocators are front and center in this story. Echolocation by bats has proven to be a virtual gold mine for colleagues studying neurobiology, while providing many rich examples of its impact on other areas of bats’ lives. In this volume we briefly review the history of the topic (reminding readers of the 1995 Hearing by Bats). We use a chapter on new findings in the phylogeny of bats to put the information that follows in an evolutionary context. This includes an examination of the possible roles of Prestin and FoxP2 genes and various anatomical features affecting bat vocalizations. We introduce recent work on the role of noseleafs, ears, and other facial components on the focusing of sound and collection of echoes. ​

Recent technical developments have made it relatively simple to listen to and record the signals arthropods make, including the messages sent by species whose transmittals are inaudible without aid. Ewing (zoology, U. of Edinburgh) covers the biophysics of sound and vibration, the mechanisms of sound production, receptor mechanisms, the neuroethology of sound reception and sound production, and interspecific acoustic communication. Other chapters deal with calling, courtship, and aggressive songs; social arthropods; the genetics and evolution of song; and bioacoustic methods.

Many insects produce stridulatory sounds which may function in both intra- and interspecific communication. Studies of stridulation in Coleoptera include descriptions of morphology of sound-producing structures, sound characteristics, and manipulations of sound production to discover its function. Here I present four studies that further our understanding of the role of sound in North American Nicrophorus, and suggest both practical and theoretical applications for understanding stridulation in behavioral and conservation contexts. In the first study, I characterize the sound produced by eight different Nicrophorus species, examining characteristics of both the signals and stridulatory apparati for variation across species, with analysis of relationships between sound and morphology. In the second study, I apply this knowledge to an aspect of conservation; specifically, whether structural damage to elytron affects the fecundity of the endangered American burying beetle, Nicrophorus americanus. Then, I address the use of sound as an intraspecific signal during contests for obligate breeding resources. And finally, I address the function of stridulation for reproductive behaviors and fecundity. I found that induced Nicrophorus stridulations are biphastic and broadband with weak dominant frequency structure, and that sound and stridulatory structures differ among the eight species%studied. These differences in sound do not relate to any of the morphological characters quantified in this study. In addition, structural alteration of the elytra changes the temporal characteristics of female N. americanus stridulation and results in reduced fecundity. Finally, removing sound does not influence contest outcomes in male N. marginatus; body size remains the best predictor of competitive ability. Removing sound does not affect reproductive success. The evidence presented in these studies indicates that stridulations are likely playing more of a role in interspecific communication, such as an aposematic warning signal, or possibly as an intraspecific aggregation signal between parent and offspring. Future investigations are focused on the sounds produced in the context of reproductive behaviors such as competition for resources, copulation and nest preparation, and brood care.
