A Manual of Land and Fresh Water Vertebrate Animals of the United States (exclusive of Birds)
Author: Henry Sherring PrattPublisher:
ISBN:
Category : Animals
Languages : en
Pages : 454
Book Description
The naturalist frequently finds that to learn to identify species is a most difficult task, and yet nothing is more important to his work. He finds that species are not separated merely on shape and colour, but on structural peculiarities which frequently are connected with particular habits. This is especially the case in vertebrate animals, which in Great Britain, with its very limited number of forms, may be identified in a haphazard manner by elimination. This is impossible in a country where different climatic areas interdigitate and where there are many species, as the United States, which for the purpose of the naturalist is a continent. Here Prof. H. S. Pratt ?fills the bill ?by his ?Vertebrate Animals of the United States,? which, however, omits birds. A short account of each group is given, the anatomical features dividing it up into sub-groups and families being usually illustrated. Where neces-sary, special features for families are described and then follow keys to the genera, descriptions of the same and keys to their species. The whole closes with a good bibliography and a glossary of technical terms. The short descriptions of each species, with mention of their geographical distributions and habitats, are excellent, and the tabulation of the sub-species most useful. We learn that there are about 600 species of freshwater fishes, 70 of newts and 61 of frogs and toads we are given a key by which their tadpoles and eggs can be identified-300 reptiles and a wide series of mammals belonging to 9 orders. We characterise this publication as a book for ready reference, such as should be on the shelves of all American naturalists.

The North American Model of Wildlife Conservation

Book Description
The foremost experts on the North American Model of Wildlife Conservation come together to discuss its role in the rescue, recovery, and future of our wildlife resources. At the end of the nineteenth century, North America suffered a catastrophic loss of wildlife driven by unbridled resource extraction, market hunting, and unrelenting subsistence killing. This crisis led powerful political forces in the United States and Canada to collaborate in the hopes of reversing the process, not merely halting the extinctions but returning wildlife to abundance. While there was great understanding of how to manage wildlife in Europe, where wildlife management was an old, mature profession, Continental methods depended on social values often unacceptable to North Americans. Even Canada, a loyal colony of England, abandoned wildlife management as practiced in the mother country and joined forces with like-minded Americans to develop a revolutionary system of wildlife conservation. In time, and surviving the close scrutiny and hard ongoing debate of open, democratic societies, this series of conservation practices became known as the North American Model of Wildlife Conservation. In this book, editors Shane P. Mahoney and Valerius Geist, both leading authorities on the North American Model, bring together their expert colleagues to provide a comprehensive overview of the origins, achievements, and shortcomings of this highly successful conservation approach. This volume • reviews the emergence of conservation in late nineteenth–early twentieth century North America • provides detailed explorations of the Model's institutions, principles, laws, and policies • places the Model within ecological, cultural, and socioeconomic contexts • describes the many economic, social, and cultural benefits of wildlife restoration and management • addresses the Model's challenges and limitations while pointing to emerging opportunities for increasing inclusivity and optimizing implementation Studying the North American experience offers insight into how institutionalizing policies and laws while incentivizing citizen engagement can result in a resilient framework for conservation. Written for wildlife professionals, researchers, and students, this book explores the factors that helped fashion an enduring conservation system, one that has not only rescued, recovered, and sustainably utilized wildlife for over a century, but that has also advanced a significant economic driver and a greater scientific understanding of wildlife ecology.
