The Calls Of Frogs And Toads

These superb collections of field recordings and descriptions offer unparalleled access to the sounds and calls of numerous popular and less well known birds and amphibians. Each book and CD provides an introduction to the sound repertoire of species living in eastern and central North America--a variety of calls from each species are included, along with an in-depth description and explanation of their significance. In addition to color photographs of the most common species, the text offers a fascinating look at the science of avian and amphibian calls, making these guides indispensable aids for the outdoor enthusiast.

Covering all 101 species of frogs in the United States and Canada, this book contains natural history information, identification tips, range and habitat information, summaries of behavior, and descriptions of calls. A 70-minute audio compact disc includes the calls of nearly every species.

A comprehensive, authoritative, and fun-to-read identification guide enumerates the distinguishing characteristics of frogs and toads found throughout the southeastern United States and discusses their morphology, the main groups to be found in the Southeast, their habitats and distribution, life cycles, behavior, and conservation.

In this eloquent plea for compassion and respect for all species, journalist and gardener Nancy Lawson describes why and how to welcome wildlife to our backyards. Through engaging anecdotes and inspired advice, profiles of home gardeners throughout the country, and interviews with scientists and horticulturalists, Lawson applies the broader lessons of ecology to our own outdoor spaces. Detailed chapters address planting for wildlife by choosing native species; providing habitats that shelter baby animals, as well as birds, bees, and butterflies; creating safe zones in the garden; cohabiting with creatures often regarded as pests; letting nature be your garden designer; and encouraging natural processes and evolution in the garden. The Humane Gardener fills a unique niche in describing simple principles for both attracting wildlife and peacefully resolving conflicts with all the creatures that share our world.

"Ohio's resident amphibians currently include 25 species and subspecies of salamanders, a complex of unisexual ambystomatid salamanders, and 14 species of frogs and toads. Existing, comprehensive works of amphibians for Ohio are dated and out-of-print. Given this deficiency, and pressured by recent survey and monitoring activity and current research needs, the decision to produce a comprehensive book about Ohio's amphibians, which this volume represents, quickly followed. Focusing on verifiable information about the amphibian species of Ohio, the core of this tome is comprised of 37 chapters, organized by sections on salamanders and on frogs and toads, covering all amphibians in Ohio that have been documented and vouchered. Preceding these taxonomic, species-oriented chapters are sections on the history of herpetological work in Ohio, a summary of the Ohio environment in which its amphibian species exist, informative introductions to amphibian systematics, brief summaries of the two groups, and keys to adult and larval stages. Following the species accounts are sections on potential occurences in Ohio; on species ranking based on conservation status and knowledge; on amphibian conservation; on amphibian distribution; on environmental applications; and, a summary. Completing the book are two appendices involving field and vouchering/documentation techniques, a glossary, a combined and comprehensive listing of cited literature, and an index. This book is both scientifically accurate and written in a style suitable for the complete spectrum of individuals and entities who are professionally or casually involved or interested in amphibians"--Abstract, page iii.

Frogs of Southern Africa - a Complete Guide is an authoritative and comprehensive guide that covers all aspects of frog and toad biology and behaviour. Now updated and including recently discovered species, it has a fascinating introduction that unpacks frog biology, along with a full illustrated identification key. Stunning full-colour photographs of both frogs and tadpoles accompany distribution maps and authoritative text for each species; and QR codes link readers directly to their frog calls.

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.

Offers substantial information designed for use by both amateurs and specialists and useful to residents of other Upper Midwest states and bordering Canadian provinces as well. Introductory chapters present the history of herpetology in Minnesota, the preferred habitats of these species, techniques

Featuring more than three hundred color photographs and nearly fifty distribution maps, Snakes of the Southeast is stuffed with both entertaining and detailed, in-depth information. Includes and explores size charts, key identifiers (scales, body shape, patterns, and color), descriptions of habitat, behavior and activity, food and feeding, reproduction, predators and defense, and conservation.
