With nearly 6,000 species currently identified, frogs and toads are the most familiar and abundant amphibians on the planet. Frogs and Toads of the World is a comprehensive guide to the natural history of this large and diverse group of creatures. Stunningly illustrated throughout with 200 color photographs, this one-of-a-kind book traces the evolution and classification of frogs and toads, providing detailed information about each of the 49 unique families and highlighting distinctive and notable species. It vividly describes their remarkable diversity in shape, color, and...

This volume reviews, for the first time, the broad range of issues that affect the welfare of commercially farmed ratites. Although ratites incorporate several families of flightless birds this book focuses on the most commonly farmed ratites, the ostrich, emu and rhea. The readers are taken on a journey through all sectors of the industry, which include breeding, incubation, hatching, brooding, rearing, growth, transport and processing, with an emphasis on husbandry and management protocols that can impact bird welfare and health. Also discussed is the structure and sensory innervation of...

This is the first ever monumental and scientific documentation of the faunal wealth of the Indian Desert state of Rajasthan, covering the species diversity, distribution and conservation status. A scholarly contribution to the field of knowledge, it provides novel and vital information on the vertebrate faunal heritage of India s largest state.

Broadly falling under the Indo-Malaya Ecozone, the three major biomes of Rajasthan include Deserts and Xeric Shrublands; Tropical and Sub-tropical Dry Broadleaf Forests and Tropical and Sub-tropical Moist Broadleaf Forests and...

The book aims at synthesizing our current knowledge of Acipenser sturio and its management. This species, one of the most widespread sturgeon species all over Western Europe ranging from the Black Sea to the Baltic, is now on the verge of extinction. Major aspects of its biology and management, including mismanagement, are provided in a historic perspective. Similarly, the changes in the restoration programs (in situ and ex situ) initiated in France and Germany are presented. As the species occurred in sympatry with Acipenser oxyrinchus in Germany and Poland and very recently in France as...

Reef fish spawning aggregations, ranging from small groups to many tens of thousands of individuals, are spectacular but poorly known natural phenomena whereby fish assemble at specific times and locations to spawn. For some species these large groups may be the only form of reproduction, the high fish numbers briefly giving a false impression of stability and abundance-an 'illusion of plenty'. They are often a focus for intensive seasonal fishing because of their predictability and because many important commercial fishes form them. Highly vulnerable to overexploitation, many aggregations...

Easter Island (Rapanui) is the most remote inhabited island in the Pacific Ocean and the easternmost in Oceania. Much has been written on the origin of its first inhabitants and the enormous stone statues they carved and erected, but little exists on the island's biota. Knowing that very few species of fishes had been reported for Easter Island, John Randall went there in 1969, with the support of the National Geographic Society, to study the fish fauna. He was joined during revisits in 1988 and 1989 by the island's medical doctor, Alfredo Cea. They published the Rapanui names of fishes in...

Techniques and theory for processing otoliths from tropical marine fish have developed only recently due to an historic misconception that these organisms could not be aged. Otoliths are the most commonly used structures from which daily, seasonal or annual records of a fish s environmental history are inferred, and are also used as indicators of migration patterns, home range, spatial distribution, stock structure and life history events. A large proportion of projects undertaken on tropical marine organisms involve removal and processing of calcified structures such as otoliths,...

This book examines the contents, influence, and potential of a personal selection of modern books published over the last fifty years that have been relevant to improving welfare. The works selected comprise three earlier classics that mainly deal with animal experimentation and intensive farming, as well as five that concentrate on specific subject areas, namely history, science, applied ethics, politics and law, that are important to protecting the welfare of animals against suffering inflicted by humans. The books are arranged in the order of their publication date, and for each one a...

The author proposed the satoumi concept, analogous to the satoyama concept on land, as coastal sea with high biodiversity and productivity in harmony with human interaction in 1998. The concept for environmental conservation in the coastal seas has been widely accepted and was included in the Japanese national policy of Strategy for Establishment of an Environmental Nation in 2007. This book is a translation of the author s Japanese book (2010) in response to concerns and questions about satoumi, including: Does biodiversity increase as a result of human interaction in coastal seas? Do the...

This is the first ever monumental and scientific documentation of the faunal wealth of the Indian Desert state of Rajasthan. This volume, the second of two, provides a comprehensive picture of the conservation efforts undertaken to prevent further degradation of the condition of Rajasthan's faunal wealth. A scholarly contribution to the field of knowledge, it provides novel and vital information on wildlife preservation initiatives in India's largest state. Broadly falling under the Indo-Malaya Ecozone, the three major biomes of Rajasthan include deserts and xeric shrublands, tropical and...

Despite their abundance in many parts of North America, salamanders have generally been neglected by all but a few specialists. In this book first published in 1943 Sherman C. Bishop discusses in a lively but authoritative manner the 126 species and subspecies of salamanders that are known to exist in the United States, Canada, and Baja California.

Group by group, Bishop describes salamanders in accounts that give the common and technical names, type of locality, range, habitat, size, anatomical characteristics, color, breeding habits, and relationships all in a uniform arrangement...

The book will cover the entire range of the Painted Stork--beyond its stronghold in India and Sri Lanka to other countries--E Asia as well. For the sake of comparison, relevant information will be included about the other species of storks--both solitary as well as colonial, of Asia, as well as those in other parts of the world. Certainly plenty of references will be made about the work done on the American Wood Stork.

Studies are underway in order to better understand the role of the monsoon rains on the nesting pattern of Painted Stork, besides attempting a review of the global...
