The plains vizcacha (Lagostomus maximus) is a remarkable rodent of the Neotropic given several peculiar aspects of its biology, some of them quite unique among rodents or even among mammals. This book gathers specialists studying plains vizcachas from very different approaches, including paleontology, systematics, morphology, physiology, development and conservation. It is divided in two Parts, 1) Evolutionary History, and 2) Morphology, Development and Physiology. It will surely be a required reading for any researcher working with caviomorph rodents, mastozoology of the Neotropics or internal anatomy and physiology of mammals.

Combining research approaches from biology, philosophy and linguistics, the field of Biosemiotics proposes that animals, plants and single cells all engage in semiosis – the conversion of objective signals into conventional signs. This has important implications and applications for issues ranging from natural selection to animal behavior and human psychology, leaving biosemiotics at the cutting edge of the research on the fundamentals of life.

Foreword by Phillip V. Tobias
The introduction of rhesus macaques to Cayo Santiago, Puerto Rico in 1938, and the subsequent development of the CPRC for biomedical research, continues its long history of stimulating studies in physical anthropology. The CPRC monkey colonies, and the precise demographic data on the derived skeletal collection in the Center’s Laboratory of Primate Morphology and Genetics (LPMG), provide rare opportunities for morphological, developmental, functional, genetic, and behavioral studies across the life span of rhesus macaques as a species, and as a primate model for humans. The book grows out of a symposium Wang is organizing for the 78th annual meeting of the American Association of Physical Anthropologists to be held in April 2009.

This collection of reviews will be of considerable interests to biologists and MDs working on any aspect of cardiovascular function. With state-of-the-art reviews written by competent experts in the field, the content is also of interest for MSc and PhD students in most fields of cardiovascular physiology.

How did life originate in the universe? How did it all start after the creation of matter and the formation of elements in the stars? What are the pathways from the first organic molecules in space to the evolution of complex life forms on Earth and perhaps elsewhere? And how will it all end? The Universe itself sets the stage for the very interdisciplinary field of astrobiology that attempts to answer such questions, the central one being: What is the (cosmic) recipe for life? Currently there are only very few known elements in this vast mosaic. This book bridges a gap in the literature by bringing together leading specialists from different backgrounds who lecture on their fields, with close relevance to astrobiology, providing tutorial accounts that lead all the way to the forefront of research. The book will thus be useful for students, lecturers and reseachers alike.

This book aims to understand biological evolution through a physical approach, focusing on the macroscopic aspects of the biological genome. Readers will discover the connection between genomic information and the harmony of biological systems, a relationship that remains elusive to many researchers in biological sciences.

The Lymnaeidae (also known as ‘pond snails’) are a species-rich and globally distributed family of freshwater snails, many species of which are known to be hosts of parasitic trematodes (such as the liver fluke, Fasciola hepatica). Written by world-leading experts in the field, this book covers a wealth of topics ranging from the phylogeny and taxonomy of lymnaeid snails to their relationships with helminths and their impact on public and veterinary health. It provides an overview of the species richness, evolution, ecology, biogeography and fossil record of the family. A considerable number of chapters are devoted to the economic and medical importance of lymnaeids, their involvement in the transmission of fascioliasis and other zoonotic diseases. Special chapters deal with the molecular and morphological identification of the Lymnaeidae, their rearing in the laboratory and experimental approaches to their study.

This book timely provides high-quality records of 32 PTB sections across different depositional settings from terrestrial to marine facies in South China, including descriptions of lithologies, high-resolution correlation of key boundaries and fossil occurrences at each section. This book also analyzes the patterns and processes of the community and ecosystem evolution over space and through time in the lead to the end-Permian mass extinction, and critically analyzes the mostly debated hypothesis, anoxia and volcanism, which were considered as the causes of mass extinction, based on the data from the studied sections of South China, together with materials from other regions of the world.

"Near time" -an interval that spans the last 100,000 years or so of earth history-qualifies as a remarkable period for many reasons. From an anthropocentric point of view, the out­ standing feature of near time is the fact that the evolution, cultural diversification, and glob­ al spread of Homo sapiens have all occurred within it. From a wider biological perspective, however, the hallmark of near time is better conceived of as being one of enduring, repeat­ ed loss. The point is important. Despite the sense of uniqueness implicit in phrases like "the biodiversity crisis," meant to convey the notion that the present bout of extinctions is by far the worst endured in recent times, substantial losses have occurred throughout near time. In the majority of cases, these losses occurred when, and only when, people began to ex­ pand across areas that had never before experienced their presence. Although the explana­ tion for these correlations in time and space may seem obvious, it is one thing to rhetori­ cally observe that there is a connection between humans and recent extinctions, and quite another to demonstrate it scientifically. How should this be done? Traditionally, the study of past extinctions has fallen largely to researchers steeped in such disciplines as paleontology, systematics, and paleoecology. The evaluation of future losses, by contrast, has lain almost exclusively within the domain of conservation biolo­ gists. Now, more than ever, there is opportunity for overlap and sharing of information.

Research in whale origins is now in an explosive phase, with a cascade of discoveries adding to our understanding of the evolutionary pattern and a suite of new techniques being applied to address new questions. The objective of this volume is to provide a snapshot of this explosion. The volume paints the scene with a broad brush. Taken together the chapters clearly indicate that cetacean origins is a field that is dynamic, multidisciplinary, and that the end of the explosive phase is not in sight.

Population genetics occupies a central role in a number of important biological and social undertakings. It is fundamental to our understanding of evolutionary processes, of plant and animal breeding programs, and of various diseases of particular importance to mankind.

In very general terms, "scaling" can be defined as the structural and func­ tional consequences of differences in size (or scale) among organisms of more or less similar design. Interest in certain aspects of body size and scaling in primate biology (e. g. , relative brain size) dates to the turn of the century, and scientific debate and dialogue on numerous aspects of this general subject have continued to be a primary concern of primatologists, physical an­ thropologists, and other vertebrate biologists up to the present.

This unique volume investigates the relationships of primates at the ordinal and higher classificatory levels from a variety of interdisciplinary viewpoints. Individual chapters examine the origin and evolution of gliding in early Cenozoic Dermoptera, the ontogeny of the tympanic floor in Archontans, the role of the neurosciences in primate evolutionary biology, and many other subjects. The work will be of particular interest to primatologists, zoologists, and systematists.

This volume brings together a series of papers that address the topic of reconstructing behavior in the primate fossil record. The literature devoted to reconstructing behavior in extinct species is ovelWhelming and very diverse. Sometimes, it seems as though behavioral reconstruction is done as an afterthought in the discussion section of papers, relegated to the status of informed speculation. But recent years have seen an explosion in studies of adaptation, functional anatomy, comparative sociobiology, and development. Powerful new comparative methods are now available on the internet. At the same time, we face a rapidly growing fossil record that offers more and more information on the morphology and paleoenvironments of extinct species. Consequently, inferences of behavior in extinct species have become better grounded in comparative studies of living species and are becoming increas­ ingly rigorous.

For the first time experts in the area of signalling research with a focus on the ARF family have contributed to the production of a title devoted to ARF biology. A comprehensive phylogenetic analysis of the ARF family, tables of the ARF GEFs and ARF GAPs, and more than a dozen chapters describing them in detail are provided. The impact of the ARF proteins on widely diverse aspects of cell biology and cell signalling can be clearly seen from the activities described; including membrane traffic, lipid metabolism, receptor desensitization, mouse development, microtubule dynamics, and bacterial pathogenesis. Anyone interested in understanding the complexities of cell signalling and the integration of signalling networks will benefit from this volume.
