DOWNLOAD EBOOKThis is the most thorough treatment ever undertaken on the Sciuridae and promises to be the definitive book on squirrels for decades to come. Squirrels of the World, written by scientists with more than 100 years of collective experience studying these popular mammals, is the first comprehensive examination of all 285 species of squirrels worldwide. The authors reveal virtually every detail of the family Sciuridae, which includes ground squirrels, tree squirrels, flying squirrels, prairie dogs, and chipmunks. Each species—from the familiar gray squirrel of American backyards to the exotic and endangered woolly flying squirrel of Pakistan—is described in a detailed account that includes distinguishing characteristics, ecology, natural history, conservation status, and current threats to its existence. Squirrels of the World includes • stunning color photographs that document rare and unusual squirrels as well as common varieties • evolution, morphology, ecology, and conservation status • colorful range maps marking species distribution • images of the skull of each genus of squirrel • extensive references

DOWNLOAD EBOOKThe case history approach has an impressive record of success in a variety of disciplines. Collections of case histories, casebooks, are now widely used in all sorts of specialties other than in their familiar appli cation to law and medicine. The case method had its formal beginning at Harvard in 1871 when Christopher Lagdell developed it as a means of teaching. It was so successful in teaching law that it was soon adopted in medical education, and the collection of cases provided the raw material for research on various diseases. Subsequently, the case history approach spread to such varied fields as business, psychology, management, and economics, and there are over 100 books in print that use this approach. The idea for a series of Casehooks in Earth Science grew from my experience in organizing and editing a collection of examples of one variety of sedimentary deposits. The prqject began as an effort to bring some order to a large number of descriptions of these deposits that were so varied in presentation and terminology that even specialists found them difficult to compare and analyze. Thus, from the beginning, it was evident that something more than a simple collection of papers was needed. Accordingly, the nearly fifty contributors worked together with George de Vries Klein and me to establish a standard format for presenting the case histories.

DOWNLOAD EBOOKTo most biologists, sociobiology represents the concept of strict Darwinian individual selection married to an analytical application of ecological principles and brought to bear on social behavior in an unusually exciting and productive way. Joining the biologists are a small number of social scientists. But there are radically divergent views as to how the field should be delimited, and sociobiology is one of the most widely discussed fields in biology and anthropology today. The symposium on which this book is based was arranged by a biologist and an anthropologist. The participants, leaders in their fields, ably present contrasting and responsible views on current issues. This is the first collection of essays on sociobiology in which opposing views are aired. It is an exciting, timely book and an important historical document.

DOWNLOAD EBOOKThe order Rodentia is the most abundant and successful group of mammals, and it has been a focal point of attention for compar ative and evolutionary biologists for many years. In addition, rodents are the most commonly used experimental mammals for bio medical research, and they have played a central role in investi gations of the genetic and molecular mechanisms of speciation in mammals. During recent decades, a tremendous amount of new data from various aspects of the biology of living and fossil rodents has been accumulated by specialists from different disciplines, ranging from molecular biology to paleontology. Paradoxically, our understanding of the possible evolutionary relationships among different rodent families, as well as the possible affinities of rodents with other eutherian mammals, has not kept pace with this information "explosion. " This abundance of new biological data has not been incorporated into a broad synthesis of rodent phylo geny, in part because of the difficulty for any single student of rodent evolution to evaluate the phylogenetic significance of new findings from such diverse disciplines as paleontology, embryology, comparative anatomy, molecular biology, and cytogenetics. The origin and subsequent radiation of the order Rodentia were based primarily on the acquisition of a key character complex: specializations of the incisors, cheek teeth, and associated mus culoskeletal features of the jaws and skull for gnawing and chewing.

DOWNLOAD EBOOKTen years ago a symposium on Cytotaxonomy 'was held in London (Proc. Linn. Soc. Lond. 169:110, 1958) in which a first attempt was made to bring together various disciplines to discuss advances of mammalian cytogenetics and to put them into proper context with the sciences of evolution and taxonomy. The introductory remarks by \V. B. Turrill to that symposium, essentially an admonishment to be tolerant of the short comings of our respective disciplines, would be a most appropriate begin ning to this conference as ,,'ell. However, the meeting held at Hanover was conceived more along the lines of remarks made by R. B. Seymour Se,,'ell in his presidential address to the same society: "It has been said that scientists in this search for truth are nowadays too much concerned with the accumulation of facts, and make too little use of their imagina tion in their attempts to explain such facts as they have accumulated. " (In "The continental drift theory and the distribution of the Copepoda," ibid. 166:149, 1956. ) \\Tith this as a background, two years ago we held the first of a series of loosely-structured conferences on reproductive failure in the relaxing atmosphere of this small New England college community. The manu scripts of that meeting have been published (Comparative Aspects of Re productive Failure, Springer-Verlag New York Inc. , 1967).
