Nhan đề: Observing animal behaviour : design and analysis of quantitative data / Marian Stamp Dawkins Số phân loại : 591.50723 M109; Đặc điểm vật lý: viii, 158 p. : ill. ; 24 cm
*Tóm tắt : Observing Animal Behaviour takes the reader through all these stages: from the initial observations, to the formulation of hypotheses, and their subsequent testing with further systematic observations. Although designed principally as a companion text for advanced undergraduate and students taking courses in animal behavior, this accessible text will be essential reading for anyone wanting to study animal behavior using observational methods rather than experimentation, and assumes no previous knowledge of animals, statistics or scientific method. It will be of particular relevance and use to those professional researchers and consultants in the behavioral sciences who seek a compact but comprehensive introduction to the quantitative observation of animal behavior .

*Tóm tắt : Group Living is a widespread phenomenon within the animal kingdom and has attracted considerable attention in a number of different contexts. This book is focused on the unifying concepts regarding group behaviour that have been developed over the last two decades. The authors set out to discuss the mechanisms that govern the evolution and maintenance of grouping behaviour throughout the animal kingdom, and the ecological factors that control observed group size and group composition in particular situations. Although the book's emphasis is on the elaboration of a conceptual framework, extensive examples and case studies illustrate the diversity of grouping phemonema across taxonomic boundaries, and demonstrate the general applicability of the concepts involved. This book will familiarise the reader with the latest ideas on the ecology and evolution of group-living animals, providing a summary and critical synthesis of the extensive and diverse literature on the subject .

*Tóm tắt : The authors, one a theoretician the other a fieldworker, introduce a sense of order to this chaos. A significant cause of confusion has been the tendency for different researchers to use either the same term with different meanings, or different terms with the same meaning. The authors attempt to clarify these differences. A second cause of confusion has arisen because many biologists continue to assume that there is only one correct explanation for signal reliability. The authors argue that the reliability of signals is maintained in several ways, relevant in different circumstances, and that biologists must learn to distinguish between them. In this book they explain the different theories, give examples of signalling systems to which one or another theory applies, and point to the many areas where further work, both theoretical and empirical, is required .

*Tóm tắt : Caterpillars are as varied, fascinating, and often as colorful as the adult butterflies they become. This is the most comprehensive guide to these creatures available. It contains all the information necessary to find and identify the caterpillars of North America--from Two-tailed Swallowtails, some of the largest butterfly caterpillars at just over two inches when fully grown, to tiny Western Pygmy-Blues. Caterpillar seekers will learn how to distinguish between butterfly caterpillars and moth caterpillars, where and how to find caterpillars, and the visual differences between young and older caterpillars .

Nhan đề: Naturalized reptiles and amphibians of the world / Christopher Lever Số phân loại : 597.916 CHR313; Đặc điểm vật lý: 318 p. : ill. ; 26 cm
*Tóm tắt : This book describes how the various alien reptiles and amphibians now living in the wild throughout the world were first introduced, how they subsequently became naturalized, their present distribution and status in those countries to which they were introduced, and their ecological and socio-economic impact on the native biota and local economies. Many species have had a more or less neutral impact, being neither beneficial nor harmful. However, several have had a positive ecological or socio-economic impact, while some such as the cane toad, have had an extremely destructive effect.The criteria for inclusion of a species are that it should have been imported from its natural range to a new country by human agency--either accidentally or deliberately--and that it should currently be established in the wild in self-maintaining and self-perpetuating populations unsupported by and independent of mankind .

*Tóm tắt : Jackson Pollock, Georgia O'Keeffe, Andy Warhol, Julian Schnabel, and Laurie Anderson are just some of the major American artists of the twentieth century. From the 1893 Chicago World's Fair to the 2000 Whitney Biennial, a rapid succession of art movements and different styles reflected the extreme changes in American culture and society, as well as America's position within the international art world... .
