Available in PDF, EPUB and Kindle. Book excerpt: In a Panamanian pond, male túngara frogs (Physalaemus pustulosus) gather in choruses, giving their "advertisement" call to the females that move among them. If a female chooses to make physical contact with a male, he will clasp her and eventually fertilize her eggs. But in vying for the females, the males whose calls are most attractive may also attract the interest of another creature: the fringe-lipped bat, a frog eater. In the Túngara Frog, the most detailed and informative single study available of frogs and their reproductive behavior, Michael J. Ryan demonstrates the interplay of sexual and natural selection. Using techniques from ethology, behavioral ecology, sensory physiology, physiological ecology, and theoretical population genetics in his research, Ryan shows that large males with low-frequency calls mate most successfully. He examines in detail a number of explanations for the females' preferences, and he considers possible evolutionary forces leading to the males' success. Though certain vocalizations allow males to obtain mates and thus should be favored by sexual selection, this study highlights two important costs of such sexual displays: the frogs expand considerable energy in their mating calls, and they advertise their whereabouts to predators. Ryan considers in detail how predators, especially the frige-lipped bat (Trachops cirrhosus), affect the evolution of the túngara frog's calls.

Download or read book Condition dependent Signaling in a Neotropical Frog written by Kyle Osborne Wilhite and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Communication facilitates almost every interaction between animals. Sexual selection produces signals that happen to be very energetically costly to produce. Only males who are in high condition should be able to produce these signals after basic individual needs are met. Here we investigate the effect of food intake/the ability to forage on condition and how condition influences the production of these sexual signals in the túngara frog. We recorded male calls in acoustic boxes for 9 days. After a period of no food, we found that males change certain aspects of their sexual advertisement call that are usually attractive to females. We then tested to see if females show a preference for a high or low condition male to which they preferred the high condition male. We then show that condition can predict a male’s ability to compete against other males for access to females. Males in low condition call less, make fewer complex calls, show changes in stereotypically sexually selected traits, and are less attractive to females

Download or read book Sexual Selection written by Malte Andersson and published by Princeton University Press. This book was released on 2019-12-31 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bright colors, enlarged fins, feather plumes, song, horns, antlers, and tusks are often highly sex dimorphic. Why have males in many animals evolved more conspicuous ornaments, signals, and weapons than females? How can such traits evolve although they may reduce male survival? Such questions prompted Darwin's perhaps most scientifically controversial idea--the theory of sexual selection. It still challenges researchers today as they try to understand how competition for mates can favor the variety of sex-dimorphic traits. Reviewing theoretical and empirical work in this very active field, Malte Andersson, a leading contributor himself, provides a major up-to-date synthesis of sexual selection. The author describes the theory and its recent development; examines models, methods, and empirical tests; and identifies many unsolved problems. Among the topics discussed are the selection and evolution of mating preferences; relations between sexual selection and speciation; constraints on sexual selection; and sex differences in signals, body size, and weapons. The rapidly growing study of sexual selection in plants is also reviewed. This volume will interest students, teachers, and researchers in behavioral ecology and evolutionary biology.
Download or read book Leks written by Jacob Höglund and published by Princeton University Press. This book was released on 2014-07-14 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution of leks--clusters of small territories where males congregate and display in order to attract mates--is of central issue in behavioral ecology, because of the insights it offers into female mate choice, sexual selection, and the evolution of mating systems. In the first book on the subject, Jacob Höglund and Rauno Alatalo draw together existing knowledge on two main aspects of lekking. Why do leks evolve in some species and not in others? Why do females of certain lekking species select their mates even though such behavior reaps few or no material benefits for them? In each case they emphasize the importance of understanding the selective forces that act on individuals in natural populations. Höglund and Alatalo synthesize the available information on lekking in all animal groups and suggest new areas of research. Originally published in 1995.

Topics covered range from communication systems in mice, birds, and primates to the perception and processing of language and music by humans.
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 The Ecology and Behavior of Amphibians written by Kentwood D. Wells and published by University of Chicago Press. This book was released on 2010-02-15 with total page 1162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Consisting of more than six thousand species, amphibians are more diverse than mammals and are found on every continent save Antarctica. Despite the abundance and diversity of these animals, many aspects of the biology of amphibians remain unstudied or misunderstood. The Ecology and Behavior of Amphibians aims to fill this gap in the literature on this remarkable taxon. It is a celebration of the diversity of amphibian life and the ecological and behavioral adaptations that have made it a successful component of terrestrial and aquatic ecosystems. Synthesizing seventy years of research on amphibian biology, Kentwood D. Wells addresses all major areas of inquiry, including phylogeny, classification, and morphology; aspects of physiological ecology such as water and temperature relations, respiration, metabolism, and energetics; movements and orientation; communication and social behavior; reproduction and parental care; ecology and behavior of amphibian larvae and ecological aspects of metamorphosis; ecological impact of predation on amphibian populations and antipredator defenses; and aspects of amphibian community ecology. With an eye towards modern concerns, The Ecology and Behavior of Amphibians concludes with a chapter devoted to amphibian conservation. An unprecedented scholarly contribution to amphibian biology, this book is eagerly anticipated among specialists.
Download or read book Animal Vocal Communication written by Eugene S. Morton and published by Cambridge University Press. This book was released on 2017-04-06 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: How do animals communicate using sounds? How did animal vocal communication arise and evolve? Exploring a new way to conceptualize animal communication, this new edition moves beyond an earlier emphasis on the role of senders in managing receiver behaviour, to examine how receivers' responses influence signalling. It demonstrates the importance of the perceiver role in driving the evolution of communication, for instance in mimicry, and thus shifts the emphasis from a linguistic to a form/function approach to communication. Covering a wide range of animals from frogs to humans, this new edition includes new sections on human prosodic elements in speech, the vocal origins of smiles and laughter and deliberately irritating sounds and is ideal for researchers and students of animal behaviour and in fields such as sensory biology, neuroscience and evolutionary biology.

Available in PDF, EPUB and Kindle. Book excerpt: All living things on earth—from individual species to entire ecosystems—have evolved through time, and evolution is the acknowledged framework of modern biology. Yet many areas of biology have moved from a focus on evolution to much narrower perspectives. Daniel R. Brooks and Deborah A. McLennan argue that it is impossible to comprehend the nature of life on earth unless evolution—the history of organisms—is restored to a central position in research. They demonstrate how the phylogenetic approach can be integrated with ecological and behavioral studies to produce a richer and more complete picture of evolution. Clearly setting out the conceptual, methodological, and empirical foundations of their research program, Brooks and McLennan show how scientists can use it to unravel the evolutionary history of virtually any characteristic of any living thing, from behaviors to ecosystems. They illustrate and test their approach with examples drawn from a wide variety of species and habitats. The Nature of Diversity provides a powerful new tool for understanding, documenting, and preserving the world's biodiversity. It is an essential book for biologists working in evolution, ecology, behavior, conservation, and systematics. The argument in The Nature of Diversity greatly expands upon and refines the arguments made in the authors' previous book Phylogeny, Ecology, and Behavior.
