Book Synopsis Signalers and Receivers by : Michael D. Greenfield
Download or read book Signalers and Receivers written by Michael D. Greenfield and published by Oxford University Press, USA. This book was released on 2002 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: In most terrestrial and aquatic habitats, the vast majority of animals transmitting and receiving communicative signals are arthropods. This book presents the story of how this important group of animals use pheromones, sound, vibration, and light for sexual and social communication. Because of their small to minute body size most arthropods have problems sending and receiving acoustic and optical information, each of which have their own severe constraints. Because of these restraints they have developed chemical signaling which is not similarly limited by scale. Presenting the latest theoretical and experimental findings from studies of signaling, it suggests that close parallels between arthropods and vertebrates reflect a very limited number of solutions to problems in behavior that are available within the confines of physical laws.

Book Synopsis The Evolution of Animal Communication by : William A. Searcy
Download or read book The Evolution of Animal Communication written by William A. Searcy and published by Princeton University Press. This book was released on 2010-01-01 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gull chicks beg for food from their parents. Peacocks spread their tails to attract potential mates. Meerkats alert family members of the approach of predators. But are these--and other animals--sometimes dishonest? That's what William Searcy and Stephen Nowicki ask in The Evolution of Animal Communication. They take on the fascinating yet perplexing question of the dependability of animal signaling systems. The book probes such phenomena as the begging of nesting birds, alarm calls in squirrels and primates, carotenoid coloration in fish and birds, the calls of frogs and toads, and weapon displays in crustaceans. Do these signals convey accurate information about the signaler, its future behavior, or its environment? Or do they mislead receivers in a way that benefits the signaler? For example, is the begging chick really hungry as its cries indicate or is it lobbying to get more food than its brothers and sisters? Searcy and Nowicki take on these and other questions by developing clear definitions of key issues, by reviewing the most relevant empirical data and game theory models available, and by asking how well theory matches data. They find that animal communication is largely reliable--but that this basic reliability also allows the clever deceiver to flourish. Well researched and clearly written, their book provides new insight into animal communication, behavior, and evolution.

Download or read book Aping Language written by Joel Wallman and published by Cambridge University Press. This book was released on 1992-10-15 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Language is regarded, at least in most intellectual traditions, as the quintessential human attribute, at once evidence and source of most that is considered transcendent in us, distinguishing ours from the merely mechanical nature of the beast. Even if language did not have the sacrosanct status it does in our conception of human nature, however, the question of its presence in other species would still promote argument, for we lack any universally accepted, defining features of language, ones that would allow us to identify it unequivocally ours from other species and contention over the crucial attributes of language are responsible for the stridency of the debate over whether nonhuman animals can learn language. Aping Language is a critical assessment of each of the recent experiments designed to impact a language, either natural or invented, to an ape. The performance of the animals in these experiments is compared with the course of semantic and syntactic development in children, both speaking and signing. The book goes on to examine what is known about the neurological, cognitive, and specifically linguistic attributes of our species that subserve language, and it discusses how they might have come into existence. Finally, the communication of nonhuman primates in nature is assayed to consider whether or not it was reasonable to assume, as the experimenters in these projects did, that apes possess an ability to acquire language.

Book Synopsis Animal Communication Networks by : P. K. McGregor
Download or read book Animal Communication Networks written by P. K. McGregor and published by Cambridge University Press. This book was released on 2005-03-31 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most animal communication has evolved and now takes place in the context of a communication network, i.e. several signallers and receivers within communication range of each other. This idea follows naturally from the observation that many signals travel further than the average spacing between animals. This is self evidently true for long-range signals, but at a high density the same is true for short-range signals (e.g. begging calls of nestling birds). This book provides a current summary of research on communication networks and appraises future prospects. It combines information from studies of several taxonomic groups (insects to people via fiddler crabs, fish, frogs, birds and mammals) and several signalling modalities (visual, acoustic and chemical signals). It also specifically addresses the many areas of interface between communication networks and other disciplines (from the evolution of human charitable behaviour to the psychophysics of signal perception, via social behaviour, physiology and mathematical models).

Download or read book Noise Matters written by R. Haven Wiley and published by Harvard University Press. This book was released on 2015-06-09 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Noise, as we usually think of it, is background sound that interferes with our ability to hear more interesting sounds. In general terms, though, it is anything that interferes with the reception of signals of any sort. It includes extraneous energy in the environment, degradation of signals in transit, and spontaneous random activity in receivers and signalers. Whatever the cause, the consequence of noise is error by receivers, and these errors are the key to understanding how noise shapes the evolution of communication. Noise Matters breaks new ground in the scientific understanding of how communication evolves in the presence of noise. Combining insights of signal detection theory with evidence from decades of his own original research, Haven Wiley explains the profound effects of noise on the evolution of communication. The coevolution of signalers and receivers does not result in ideal, noise-free communication, Wiley finds. Instead, signalers and receivers evolve to a joint equilibrium in which communication is effective but never error-free. Noise is inescapable in the evolution of communication. Wiley’s comprehensive approach considers communication on many different levels of biological organization, from cells to individual organisms, including humans. Social interactions, such as honesty, mate choice, and cooperation, are reassessed in the light of noisy communication. The final sections demonstrate that noise even affects how we think about human language, science, subjectivity, and freedom. Noise Matters thus contributes to understanding the behavior of animals, including ourselves.
