The Tungara Frog by Michael J. Ryan Pdf

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.

The Book of Frogs by Tim Halliday Pdf

“A huge, beautiful compendium of 600 frogs from around the world, from the famed poison-arrow variety on up to the intriguingly named plaintive rain frog.” —Wired With over 7,000 known species, frogs display a stunning array of forms and behaviors. A single gram of the toxin produced by the skin of the Golden Poison Frog can kill 100,000 people. Male Darwin’s Frogs carry their tadpoles in their vocal sacs for sixty days before coughing them out into the world. The Wood Frogs of North America freeze every winter, reanimating in the spring from the glucose and urea that prevent cell collapse. The Book of Frogs commemorates the diversity and magnificence of all of these creatures, and many more. Six hundred of nature’s most fascinating frog species are displayed, with each entry including a distribution map, sketches of the frogs, species identification, natural history, and conservation status. Life-size color photos show the frogs at their actual size—including the colossal seven-pound Goliath Frog. Accessibly written by expert Tim Halliday and containing the most up-to-date information, The Book of Frogs will captivate both veteran researchers and amateur herpetologists. As frogs increasingly make headlines for their troubling worldwide decline, the importance of these fascinating creatures to their ecosystems remains underappreciated. The Book of Frogs brings readers face to face with six hundred astonishingly unique and irreplaceable species that display a diverse array of adaptations to habitats that are under threat of destruction throughout the world. “If you are a serious (and I mean serious) fan of the frog, you are in for a real treat.” —Boing Boing

Becoming Animal by Nato Thompson Pdf

Contemporary artists investigate the boundaries between animal and human in a world of transgenics and dissolving distinctions; with 65 color images of new works. In an age when scientists say they can no longer specify the exact difference between human and animal, living and dead, many contemporary artists have chosen to use animals in their work—as the ultimate "other," as metaphor, as reflection. The attempt to discover what is animal, not surprisingly, leads to a greater understanding of what it means to be human. In Becoming Animal, 12 internationally known artists investigate the shifting boundaries between animal and human. Their explorations may be a barometer of things to come. The works included in Becoming Animal—which accompanies an exhibit at MASS MoCA—range from the aviary and cabinet of curiosities of Mark Dion to the gun-toting bird collages of Michael Oatman. Nicolas Lampert's machine-animal collages and Jane Alexander's corpse-like humanoids suggest a new landscape of alienation. Rachel Berwick's investigation of the last Galapagos tortoise from the island of Pinto and Brian Conley's humanized mating call of the Tungara frog question the divide between human and animal communication. Patricia Piccinini imagines a bodyguard for a bird on the edge of extinction and Ann-Sofi Siden recreates the bedroom—and paranoia—of psychologist Alice Fabian. Natalie Jeremijenko presents another installment in her ongoing Ooz, reverse-engineering the zoo, and Kathy High's installation of "trans-animals" remembers lab rats who have given their lives for science. Sam Easterson's videos allow us to see from the viewpoint of an aardvark, a tarantula, a tumbleweed; Motohiko Odani's films show a surrealistic genetically modified bestiary. Becoming Animal documents these works with eye-popping full-color images, taking us on a visual journey through an unknown world.

The Evolution of Beauty by Richard O. Prum Pdf

A FINALIST FOR THE PULITZER PRIZE NAMED A BEST BOOK OF THE YEAR BY THE NEW YORK TIMES BOOK REVIEW, SMITHSONIAN, AND WALL STREET JOURNAL A major reimagining of how evolutionary forces work, revealing how mating preferences—what Darwin termed "the taste for the beautiful"—create the extraordinary range of ornament in the animal world. In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves. But can adaptation by natural selection really account for everything we see in nature? Yale University ornithologist Richard Prum—reviving Darwin's own views—thinks not. Deep in tropical jungles around the world are birds with a dizzying array of appearances and mating displays: Club-winged Manakins who sing with their wings, Great Argus Pheasants who dazzle prospective mates with a four-foot-wide cone of feathers covered in golden 3D spheres, Red-capped Manakins who moonwalk. In thirty years of fieldwork, Prum has seen numerous display traits that seem disconnected from, if not outright contrary to, selection for individual survival. To explain this, he dusts off Darwin's long-neglected theory of sexual selection in which the act of choosing a mate for purely aesthetic reasons—for the mere pleasure of it—is an independent engine of evolutionary change. Mate choice can drive ornamental traits from the constraints of adaptive evolution, allowing them to grow ever more elaborate. It also sets the stakes for sexual conflict, in which the sexual autonomy of the female evolves in response to male sexual control. Most crucially, this framework provides important insights into the evolution of human sexuality, particularly the ways in which female preferences have changed male bodies, and even maleness itself, through evolutionary time. The Evolution of Beauty presents a unique scientific vision for how nature's splendor contributes to a more complete understanding of evolution and of ourselves.

ANURAN COMMUNICATION by RYAN MICHAEL J Pdf

In this volume, 25 scientists from around the world review the most recent advances in the study of how frogs and toads communicate. The contributors - who are experts in disciplines including animal behaviour, developmental biology, endocrinology, evolution, ecology and neurobiology - examine this amphibian order's vocal, visual and chemical signals, the physiology and energetics of their production, neural processing, related behaviours, and evolutionary implications. As the chapters demonstrate, research developments have led to further understanding of the role of the anuran larynx in sound production, how the anuran brain recognizes sound, and how both of these processes are influenced by the animal's physiological state. The contributors also discuss male-to-male call strategies as well as how female preferences for call variation contribute to sexual selection, speciation and hybridization. The text presents material about kin recognition abilities and the surprising range of visual displays by tropical anurans, and examines how the inherent structure of the auditory system might generate sensory biases that influence signal evolution.

An Immense World by Ed Yong Pdf

NEW YORK TIMES BESTSELLER A “thrilling” (The New York Times), “dazzling” (The Wall Street Journal) tour of the radically different ways that animals perceive the world that will fill you with wonder and forever alter your perspective, by Pulitzer Prize–winning science journalist Ed Yong “One of this year’s finest works of narrative nonfiction.”—Oprah Daily ONE OF THE TEN BEST BOOKS OF THE YEAR: The Wall Street Journal, The New York Times, Time, People, The Philadelphia Inquirer, Slate, Reader’s Digest, Publishers Weekly, BookPage ONE OF THE BEST BOOKS OF THE YEAR: The Globe and Mail, The New Yorker, Oprah Daily, The Washington Post, The Guardian, Smithsonian Magazine, Kirkus Reviews, Library Journal The Earth teems with sights and textures, sounds and vibrations, smells and tastes, electric and magnetic fields. In An Immense World, Ed Yong coaxes us beyond the confines of our own senses to encounter beetles that are drawn to fires, turtles that can track the Earth’s magnetic fields, fish that fill rivers with electrical messages, and even humans who wield sonar like bats. We discover that a crocodile’s scaly face is as sensitive as a lover’s fingertips, that the eyes of a giant squid evolved to see sparkling whales, that plants thrum with the inaudible songs of courting bugs, and that even simple scallops have complex vision. We learn what bees see in flowers, what songbirds hear in their tunes, and what dogs smell on the street. We listen to stories of pivotal discoveries in the field, while looking ahead at the many mysteries that remain unsolved. Funny, rigorous, and suffused with the joy of discovery, An Immense World takes us on what Marcel Proust called “the only true voyage . . . not to visit strange lands, but to possess other eyes.”

Sexual Selection by Malte Andersson Pdf

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.

Frogs by Mike Dorcas,Whit Gibbons Pdf

Frogs are amazingly diverse—ranging from the massive goliath frog, which weighs several pounds, to the recently discovered gold frog, which measures a mere three-eighths of an inch when fully grown—and have inhabited the earth for more than 200 million years. Today, however, these amphibians face more challenges than any other vertebrate group. In this fun and informative book, herpetologists Mike Dorcas and Whit Gibbons answer common and not-so-common questions people may have about these fascinating animals. Dorcas and Gibbons discuss how frogs evolved, which species currently exist in the world, and why some have recently gone extinct. They reveal what frogs eat and what eats them, their role in cultures across the globe, why many populations are declining and what we can do to reverse this dangerous trend, why there are deformed frogs, and much more. They answer expected questions such as “What is the difference between a frog and a toad?” and “Why do some people lick toads?” and unexpected ones such as “Why do some frogs lay their eggs in the leaves of trees?” and “Do frogs feel pain?” The authors’ easy-to-understand yet thorough explanations provide insight into the amazing biology of this amphibian group. In addressing conservation questions, Dorcas and Gibbons highlight the frightening implications of the current worldwide amphibian crisis, which many scientists predict will bring extinction rates experienced by frog species to levels not seen in any vertebrate animal group in millions of years. Packed with facts and featuring two color galleries and 70 black-and-white photographs, Frogs: The Animal Answer Guide is sure to address the questions on the minds of curious naturalists.

Vertebrate Sound Production and Acoustic Communication by Roderick A. Suthers,W. Tecumseh Fitch,Richard R. Fay,Arthur N. Popper Pdf

Although the fundamental principles of vocal production are well-understood, and are being increasingly applied by specialists to specific animal taxa, they stem originally from engineering research on the human voice. These origins create a double barrier to entry for biologists interested in understanding acoustic communication in their study species. The proposed volume aims to fill this gap, providing easy-to-understand overviews of the various relevant theories and techniques, and showing how these principles can be implemented in the study of all main vertebrate groups. The volume will have eleven chapters assembled from the world's leading researchers, at a level intelligible to a wide audience of biologists with no background in engineering or human voice science. Some will cover sound production in a particular vertebrate group; others will address a particular issue, such as vocal learning, across vertebrate taxa. The book will highlight what is known and how to implement useful techniques and methodologies, but will also summarize current gaps in the knowledge. It will serve both as a tutorial introduction for newcomers and a springboard for further research for all scientists interested in understanding animal acoustic signals.
