Book Description
The plainfin midshipman, Porichthys notatus, has become a model for vocal communication and auditory reception because acoustic communication plays an important role in spawning behavior in this fish species. The auditory system of the teleost fish, P. notatus, is an important sensory receiver system used to encode intraspecific social communication signals in adults, but the response properties and function of this receiver system in pre-adult stages are less known. I describe what is known about the ontogeny of auditory sensitivity in juvenile and larval stages as well as other important background information in chapter one. In chapter two, I examine the response properties of auditory evoked potentials from the midshipman saccule, the main organ of hearing in this species, to determine whether the frequency response and auditory threshold of saccular hair cells to behaviorally relevant single tone stimuli change during ontogeny. I address the question of auditory sensitivity during larval development in chapter three and discuss when in the larval stage audition begins using the innate acoustically evoked behavioral response (AEBR) as a hearing assay. Specifically, I demonstrate that auditory reception develops early in larval development and that auditory sensitivity is similar throughout all larval stages. Additionally, during ontogeny, the saccule undergoes profound growth. I examine the saccular epithelia of larval, juvenile, and adult plainfin midshipman in order to describe the morphological changes that occur in saccular ultrastructure during development. These results are described in greater detail in chapter four. The results from chapters two through four are summarized and placed into broader contexts and I suggest future studies in chapter five.

Book Description
Fish have become an important model for studying hair cell plasticity and development. Unlike mammals, the inner ears of fish continue to grow and add hair cells throughout their lifespan, and fish can regenerate hair cells after inner ear damage. The plainfin midshipman fish (Porichthys notatus) is a useful model for investigating auditory plasticity because, in addition to these more widely studied contexts of hair cell plasticity, the midshipman auditory system undergoes changes associated with the reproductive state. In chapter 1, I summarize the multiple contexts of hair cell plasticity in fish and the secondary adaptive functions of the gas-filled swim bladder as an auditory and vocal structure. I then discuss the specific questions explored in this dissertation regarding developmental and reproductive state-dependent changes to the auditory inner ear and swim bladder using the plainfin midshipman as a model. In chapter 2, I provide evidence for a reproductive state-dependent change in hair cell density and a possible cellular mechanism in vocal type I male midshipman. In chapter 3, I describe changes in sensory epithelium area, hair cell density, and total hair cell quantity in the auditory inner ear throughout ontogeny in plainfin midshipman fish. In chapter 4, I discuss a change in the morphology of the swim bladder and its proximity to the inner ear in type I males related to reproductive state, indicating a possible change in adaptive use as an auditory structure to a vocal organ. Lastly, in chapter 5, I discuss the implications of the findings in this dissertation and future directions for studying auditory-related questions in the plainfin midshipman fish.

Book Description
The reception and processing of socially relevant auditory signals is crucial for the reproduction and survival of many species including the plainfin midshipman fish, Porichthys notatus. Numerous behavioral, physiological and neuroanatomical studies have made P. notatus a robust model system for studying vocal acoustic communication. The ways in which fish are able to perceive acoustic information varies across species and I will detail the underlying morphological structures, including the swim bladder, that fish have adapted to enhance underwater hearing. I characterize the morphology of the midshipman swim bladder chapter two, in each of the three sexual phenotypes; females, type I and type II males. Using micro-computerized tomography I measure and quantify the swim bladder’s shape and relative distance to the inner ear organs in each midshipman sexual phenotype. In chapter three, using the immediate early gene cFos as a marker for neuronal activation, I quantify the response properties of gravid female midshipman to both conspecific advertisement calls and heterospecific white seabass calls. Specifically, I demonstrate the brain areas differentially activated during the perception of these socially relevant acoustic signals. To assess the role of the swim bladder in the neural processing of acoustic signals, in chapter four I conducted playback of conspecific advertisement calls to reproductive females with their swim bladders experimentally removed. Finally, in chapter five, I summarize the conclusions of my work as well as the broader implications and suggestions for future studies.

Book Description
The hearing organs of non-mammals, which show quite large and systematic differences to each other and to those of mammals, provide an invaluable basis for comparisons of structure and function. By taking advantage of the vast diversity of possible study organisms provided by the "library" that is biological diversity, it is possible to learn how complex functions are realized in the inner ear through the evolution of specific structural, cellular and molecular configurations. Insights from Comparative Hearing Research brings together some of the most exciting comparative research on hearing and shows how this work has profoundly impacted our understanding of hearing in all vertebrates.

Book Description
This volume examines fish sounds that have a proven signal function, as well as sounds assumed to have evolved for communication purposes. It provides an overview of the mechanisms, evolution and neurobiology behind sound production in fishes, and discusses the role of fish sounds in behavior with a special focus on choice of mate, sex-specific and age-specific signaling. Furthermore, it highlights the ontogenetic development of sound communication and ecoacoustical conditions in fish habitats and the influence of hormones on vocal production and sound detection. Sound Communication in Fishes offers a must-have compendium for lecturers, researchers and students working in the fields of animal communication, fish biology, neurobiology and animal behavior.

Book Description
Fish Hearing and Bioacoustics is an anthology of review papers that were presented at a special symposium to honor Arthur Popper and Richard Fay on May 25th 2013 at the Mote Marine Laboratory in Sarasota, FL. The research presentations at this conference spanned the range of disciplines covered by Fay and Popper during their long and productive careers. The book includes the following thematic areas for the papers in this special volume: morphology and anatomy of the inner ear and lateral line systems; physiology of inner ear, lateral line, and central auditory systems; acoustically mediated behavior, including communication and sound localization; and environmental influences on fish hearing and bioacoustics, including anthropogenic effects of noise on fishes. Each chapter reviews and summarizes the past studies of particular area that will lead the reader up to the current work presented at the symposium. In addition, each chapters includes a perspective of how Arthur Popper and Richard Fay have influenced their particular area of fish bio acoustic research. Each manuscript also includes a hypotheses for future studies. These hypotheses will provide a springboard for future work in each field.

Book Description
The meeting of Aquatic Noise 2013 will introduce participants to the most recent research data, regulatory issues and thinking about effects of man-made noise and will foster critical cross-disciplinary discussion between the participants. Emphasis will be on the cross-fertilization of ideas and findings across species and noise sources. As with its predecessor, The Effects of Noise on Aquatic Life: 3rd International Conference will encourage discussion of the impact of underwater sound, its regulation and mitigation of its effects. With over 100 contributions from leading researchers, a wide range of sources of underwater sound will be considered.
