Book Description
Pheromones are chemical cues that pass between members of the same species that convey specific, adaptive information. These cues, and related chemicals whose function are less well defined, are especially important to fishes because of their aquatic environments and complex behaviors. Pheromones are also of increasing interest in both basic and applied aspects of fish biology because they can be used to manipulate fish behavior and may explain phenomena such as fishery collapse. Fish Pheromones and Related Cues provides a timely synthesis of this growing body of research in freshwater and marine species and explores everything from how these chemical signals evolved, are produced, released and then processed, and finally to potential applications in fish culture and conservation. Fish Pheromones and Related Cues opens with a useful overview on the theory of chemical communication and definitions. Chapters then progress by examining the biological importance of pheromones in inter- and intra-species communication, the role these chemical cues play in a variety biological functions from reproduction to predation, and then how they evolved and are detected and recognized by fish nervous systems. Final chapters provide valuable insight into how pheromones can be measured, how pheromonal disruption can explain effects of environmental pollution, and lastly how they pheromones are being applied in real-world efforts to culture fish species and to conserve our wild populations and control invasive species. With far-reaching economic, evolutionary and ecological implications, Fish Pheromones and Related Cues will be an essential volume for anyone working in the fields of chemical communication, fish biology, fisheries science, aquatic conservation, ecology, invasive species control, and aquaculture

Book Description
California ground squirrels (Otospermophilus beecheyi) harass rattlesnakes (Crotalus oreganus) using a tail-flagging display that seemingly deters predation. Previous studies suggest that tail flagging could communicate vigilance in addition to perception of a snake. I tested the function and ontogeny of tail flagging through experiments on both free-ranging squirrels and snakes. I first used an array of network security cameras to record natural rattlesnake foraging behavior and squirrel-snake interactions. This confirmed that squirrels are the primary food item of rattlesnakes in the study population, accounting for more than 90% of all prey encounters and prey consumed. I then tested whether tail flagging signals vigilance in the absence of snakes using an experiment that simulated snake strikes on free-ranging squirrels either 1) in the presence of a rattlesnake, 2) with no snake present, or 3) in an area where squirrels had recently encountered a snake that was no longer present (vigilance treatment). Squirrels tail flagged most when interacting with a snake, but they also signaled in areas of recent snake encounters during which they responded fastest to simulated strikes and were most likely to leap away from the attack. Hence, tail flagging honestly signals vigilance even when snakes are undetected. The third part of my research examined age differences in antisnake behaviors during the detection, interaction, and attack stages of a rattlesnake encounter. Compared to adults, pups were worse at detecting snakes, performed fewer tail-flagging bouts, were less likely to investigate a hidden snake’s refuge, and reacted slower to simulated strikes. I concluded that pups avoid rattlesnakes and minimize time spent in close proximity to them to compensate for their reduced reaction times to strikes. Finally, I determined which situational context surrounding snake encounters influenced variation in snake-harassment behavior and physiological stress responses, characterized by fecal assays of corticosterone. In the absence of conspecifics, squirrels exhibited higher stress responses to snakes that persisted in their environment, and the amount of time squirrels spent harassing snakes was influenced by complex interactions between conspecific presence, snake species, and the length of time snakes stayed in the area. I also found consistent individual differences in stress responses and snake-harassment behavior, suggesting that these traits could be important targets of natural selection. Overall, my work found that tail flagging is a complex antisnake signal that can serve different functions and is influenced by both intrinsic and extrinsic factors.

Book Description
Dramatic changes in the environment, including habitat degradation and climate change, have focused attention on how individuals and populations respond to a shifting biotic and abiotic landscape. A critical step toward meeting this goal is a clear understanding of the capacity of individuals to defend themselves against threats. Changes in water q

Book Description
Modern aquaculture is faced with a number of challenges, including public concern about environmental impacts and the welfare of farmed fish. A fundamental understanding of fish biology is central to finding ways to meet these challenges and is also essential for maintaining the industry's sustainability. Furthermore, the behaviour of fish under culture situations has long been ignored despite heavy commercial losses that can result from fish stressed and hence disease-prone, due to bad husbandry techniques. This important book summarises the current understanding of the behavioural biology of farmed species and illustrates how this can be applied to improve aquaculture practice. Informative and engaging, Aquaculture & Behavior brings the reader up-to-date with major issues pertaining to aquaculture. Everyone from fish farmers to upper level students will find this book a valuable and practical resource. Libraries in universities and research establishments where animal behavior, aquaculture, veterinary and biological sciences are studied and taught should have copies of this work on their shelves.

Book Description
The Oxford Handbook of Developmental Behavioral Neuroscience is a seminal reference work in the burgeoning field of developmental behavioral neuroscience, which has emerged in recent years as an important sister discipline to developmental psychobiology. This handbook, part of the Oxford Library of Neuroscience, provides an introduction to recent advances in research at the intersection of developmental science and behavioral neuroscience, while emphasizing the central research perspectives of developmental psychobiology. Contributors to the Oxford Handbook of Developmental Behavioral Neuroscience are drawn from a variety of fields, including developmental psychobiology, neuroscience, comparative psychology, and evolutionary biology, demonstrating the opportunities to advance our understanding of behavioral and neural development through enhanced interactions among parallel disciplines.In a field ripe for collaboration and integration, the Oxford Handbook of Developmental Behavioral Neuroscience provides an unprecedented overview of conceptual and methodological issues pertaining to comparative and developmental neuroscience that can serve as a roadmap for researchers and a textbook for educators. Its broad reach will spur new insights and compel new collaborations in this rapidly growing field.

Book Description
This book is intended as a resource for students and researchers interested in developmental biology and physiology and specifically addresses the larval stages of fish. Fish larvae (and fish embryos) are not small juveniles or adults. Rather they are transitionary organisms that bridge the critical gap between the singlecelled egg and sexually immature juvenile. Fish larvae represent the stage of the life cycle that is used for differentiation, feeding and distribution. The book aims at providing a single-volume treatise that explains how fish larvae develop and differentiate, how they regulate salt, water and acid-base balance, how they transport and exchange gases, acquire and utilise energy, how they sense their environment, and move in their aquatic medium, how they control and defend themselves, and finally how they grow up.
