The past decade has seen a steady increase in studies oflemur behavior and ecology. As a result, there is much novel information on newly studied populations, and even newly discovered species, that has not yet been published or summarized. In fact, lemurs have not been the focus of an international symposium since the Prosimian Biology Conference in London in 1972. Moreover, research on lemurs has reached a new quality by addressing general issues in behavioral ecology and evolutionary biology. Although lemurs provide important comparative information on these topics, this aspect of research on lemurs has not been reviewed and compared with similar studies in other primate radiations. Thus, as did many in the field, we felt that the time was ripe to review and synthesize our knowledge of lemur behavioral ecology. Following an initiative by Gerry Doyle, we organized a symposium at the XIVth Congress of the International Primatological Society in Strasbourg, France, where 15 contributions summarized much new information on lemur social systems and their ecological basis. This volume provides a collection of the papers presented at the Strasbourg symposium (plus two reports from recently completed field projects). Each chapter was peer-reviewed, typically by one "lemurologist" and one other biologist. The first three chapters present novel information from the first long-term field studies of three enigmatic species. Sterling describes the social organization of Daubentonia madagascariensis, showing that aye-aye ranging patterns deviate from those of all other nocturnal primates.
This book provides a detailed guide to the use and interpretation of color Doppler ultrasound, CT, and MR imaging in patients with gynecological disorders. The advantages and limitations of each modality in imaging different pathologies are clearly presented, and advice is provided on the most appropriate option when ultrasound does not permit a definite diagnosis or fails to determine the precise extension of a lesion. Throughout, emphasis is placed on the importance of microscopic and macroscopic findings for a full understanding of the radiological appearances, and relevant points from the basic sciences are also highlighted. Special attention is paid to issues of differential diagnosis and imaging results that are characteristic of a particular type of lesion. The authors are recognized experts in the field who draw upon their considerable experience to provide an up-to-date reference book highly relevant to everyday clinical practice.
Master the fundamental math skills necessary to quantify and evaluate a broad range of environmental questions.<br> <br> Environmental issues are often quantitative--how much land, how many people, what amount of pollution. Computer programs are useful, but there is no substitute for being able to use a simple calculation to slice through to the crux of the problem. Having a grasp of how the factors interact and whether the results make sense allows one to explain and argue a point of view forcefully to diverse audiences.<br> <br> With an engaging, down-to-earth style and practical problem-solving approach, Ecological Numeracy makes it easy to understand and master basic mathematical concepts and techniques that are applicable to life-cycle assessment, energy consumption, land use, pollution generation, and a broad range of other environmental issues. Robert Herendeen brings the numbers to life with dozens of fascinating, often entertaining examples and problems.<br> <br> Requiring only a moderate quantitative background, Ecological Numeracy is a superb introduction for advanced undergraduate students in environmental science, planning, geography, and physical and natural sciences. It is also a valuable professional resource for environmental managers, regulators, and administrators.
