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 EBOOKThe past decade has witnessed a tremendous surge of interest in varied aspects of primate biology, encompassing virtually all disciplines of the biological sciences. Regardless of whether these studies have been approached from a paleontological, morphological, developmental, biochemical, neuroanatomical, or behavioral point of view, one under lying theme has been a common interest in the possible phylogenetic relationships suggested by the results of such studies. In some cases, sound taxonomic principles have not been followed in the interpretation of these data, and this has led to skepticism among many taxonomists with regard to the validity of some of the genealogical relationships and conclusions suggested by comparative studies of living primates. It is generally agreed that the fossil record alone provides the essential time dimension for directly observing changes in characteristics, but unfortunately this record is limited both in the number of genera represented and particularly in the incomplete nature of the available preserved material. On the other hand, extensive comparative analyses of numerous characteristics in living primates have provided additional insight into possible phylogenetic relationships, despite the lack of a time dimension. Such studies of both fossil and living primates are enhanced considerably by a cladistic analysis of the probable primitive (ancestral) or advanced (derived) condition of each character state discussed, based upon their distribution (and ontogeny, wherever possible) in a wide variety of primate and nonprimate taxa, including other eutherian mammals, marsupials, mono tremes, and reptiles.

DOWNLOAD EBOOKNearly half of the known species of mammals alive today (more than 1600) are rodents or "gnawing mammals" (Nowak and Paradiso, 1983). The diversity of rodents is greater than that of any other order of mammals. Thus, it is not surprising that the fossil record of this order is extensive and fossil material of rodents from the Tertiary is known from all continents except Antarctica and Australia. The purpose of this book is to compile the published knowledge on fossil rodents from North America and present it in a way that is accessible to paleontologists and mammalogists interested in evolutionary studies of ro dents. The literature on fossil rodents is widely scattered between journals on paleontology and mammalogy and in-house publications of museums and universities. Currently, there is no single source that offers ready access to the literature on a specific family of rodents and its fossil history. This work is presented as a reference text that can be useful to specialists in rodents (fossil or recent) as weIl as mammalian paleontologists working on whole faunas. Because the diversity of rodents in the world is essentially limitless, any monograph that included all fossil rodents would similarly be limitless. Hence, this book is limited to the re cord of Tertiary rodents of North America. The several species of South American (caviomorph) rodents that invaded North America near the end of the Tertiary are also not included in this text.

DOWNLOAD EBOOKLiving amniotes—including all mammals, birds, crocodilians, snakes, and turtles—comprise an extraordinarily varied array of more than 21,000 species. Found in every major habitat on earth, they possess a truly remarkable range of morphological, ecological, and behavioral adaptations. The fossil record of amniotes extends back three hundred million years and reveals much about modern biological diversity of form and function. A collaborative effort of twenty-four researchers, Amniote Paleobiology presents thirteen new and important scientific perspectives on the evolution and biology of this familiar group. It includes new discoveries of dinosaurs and primitive relatives of mammals; studies of mammalian chewing and locomotion; and examinations of the evolutionary process in plesiosaurs, mammals, and dinosaurs. Emphasizing the rich variety of analytical techniques available to vertebrate paleontologists—from traditional description to multivariate morphometrics and complex three-dimensional kinematics—Amniote Paleobiology seeks to understand how species are related to each other and what these relationships reveal about changes in anatomy and function over time. A timely synthesis of modern contributions to the field of evolutionary studies, Amniote Paleobiology furthers our understanding of this diverse group.

DOWNLOAD EBOOKEvolutionary History of the Primates presents a documentation and analysis of the fossil record and evolutionary history of the primates to facilitate the understanding of the genealogy, adaptations, dispersal, and taxonomy of the order. The book consists of 13 chapters; each chapter is devoted to a specific genera or higher taxa of primates. The chapters contain available information on the morphology, relationships, and adaptations of primate groups. The book clarifies discussed points or documents interpretations, and it indicates the type of fossil material available for each taxon. The text will be valuable to many researchers and students who need a source of data and interpretations about fossil primates.

DOWNLOAD EBOOKTree shrews are small-bodied, scansorial, squirrel-like mammals that occupy a wide range of arboreal, semi-arboreal, and forest floor niches in Southeast Asia and adjacent islands. Comparative aspects of tree shrew biology have been the subject of extensive investigations during the past two decades. These studies were initiated in part because of the widely accepted belief that tupaiids are primitive primates, and, as such, might provide valuable insight into the evolutionary origin of complex patterns of primate behavior, locomotion, neurobiology, and reproduction. During the same period, there has been a renewed interest in the methodology of phylogenetic reconstruction and in the use of data from a variety of biological disciplines to test or formulate hypotheses of evolutionary relationships. In particular, interest in the com parative and systematic biology of mammals has focused on analysis of phy logenetic relationships among Primates and a search for their closest relatives. Assessment of the possible primate affinities of tree shrews has comprised an important part of these studies, and a considerable amount of dental, cranio skeletal, neuroanatomical, reproductive, developmental, and molecular evi dence has been marshalled to either corroborate or refute hypotheses of a special tupaiid-primate relationship. These contrasting viewpoints have re sulted from differing interpretations of the basic data, as well as alternative approaches to the evolutionary analysis of data.
