Download or read book Mammal Teeth written by Peter S. Ungar and published by JHU Press. This book was released on 2010-10-01 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner, 2010 PROSE Award for Excellence in the Biological Sciences. Professional and Scholarly Publishing division of the Association of American Publishers In this unique book, Peter S. Ungar tells the story of mammalian teeth from their origin through their evolution to their current diversity. Mammal Teeth traces the evolutionary history of teeth, beginning with the very first mineralized vertebrate structures half a billion years ago. Ungar describes how the simple conical tooth of early vertebrates became the molars, incisors, and other forms we see in mammals today. Evolutionary adaptations changed pointy teeth into flatter ones, with specialized shapes designed to complement the corresponding jaw. Ungar explains tooth structure and function in the context of nutritional needs. The myriad tooth shapes produced by evolution offer different solutions to the fundamental problem of how to squeeze as many nutrients as possible out of foods. The book also highlights Ungar's own path-breaking studies that show how microwear analysis can help us understand ancient diets. The final part of the book provides an in-depth examination of mammalian teeth today, surveying all orders in the class, family by family. Ungar describes some of the more bizarre teeth, such as tusks, and the mammal diversity that accompanies these morphological wonders. Mammal Teeth captures the evolution of mammals, including humans, through the prism of dental change. Synthesizing decades of research, Ungar reveals the interconnections among mammal diet, dentition, and evolution. His book is a must-read for paleontologists, mammalogists, and anthropologists.
Download or read book Early Miocene Paleobiology in Patagonia written by Sergio F. Vizcaíno and published by Cambridge University Press. This book was released on 2012-10-11 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal exposures of the Santa Cruz Formation in southern Patagonia have been a fertile ground for recovery of Early Miocene vertebrates for more than 100 years. This volume presents a comprehensive compilation of important mammalian groups which continue to thrive today. It includes the most recent fossil finds as well as important new interpretations based on ten years of fieldwork by the authors. A key focus is placed on the paleoclimate and paleoenvironment during the time of deposition in the Middle Miocene Climatic Optimum (MMCO) between twenty and fifteen million years ago. The authors present the first reconstruction of what climatic conditions were like and present important new evidence of the geochronological age, habits and community structures of fossil bird and mammal species. Academic researchers and graduate students in paleontology, paleobiology, paleoecology, stratigraphy, climatology and geochronology will find this a valuable source of information about this fascinating geological formation.
Download or read book Evolutionary Relationships among Rodents written by W. Patrick Luckett and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 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 or read book Mammalian Sexuality written by Alan F. Dixson and published by Cambridge University Press. This book was released on 2021-06-03 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are more than 6000 species belonging to twenty-seven orders in the Class Mammalia. Comparative studies of this diverse and magnificent array of extant species provide valuable opportunities to formulate and test hypotheses concerning the evolution of reproduction. This is the first book to explore, in depth and breadth, the complex interrelationships that exist between patterns of mating behaviour and the evolution of mammalian reproductive anatomy and physiology. It focuses upon the role that copulatory and post-copulatory sexual selection have played during the evolution of the monotremes, marsupials and placental mammals, and examines the effects of sperm competition and cryptic female choice upon coevolution of the genitalia in the two sexes. In addition, due weight is also given to discussions of the modes of life of mammals, and to the roles played by natural selection and phylogeny in determining their reproductive traits.
Download or read book Convergent Evolution written by George R. McGhee, Jr. and published by MIT Press. This book was released on 2011-11-04 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of convergent evolution from molecules to ecosystems, demonstrating the limited number of evolutionary pathways available to life. Charles Darwin famously concluded On the Origin of Species with a vision of “endless forms most beautiful” continually evolving. More than 150 years later many evolutionary biologists see not endless forms but the same, or very similar, forms evolving repeatedly in many independent species lineages. A porpoise's fishlike fins, for example, are not inherited from fish ancestors but are independently derived convergent traits. In this book, George McGhee describes the ubiquity of the phenomenon of convergent evolution and connects it directly to the concept of evolutionary constraint—the idea that the number of evolutionary pathways available to life are not endless, but quite limited. Convergent evolution occurs on all levels, from tiny organic molecules to entire ecosystems of species. McGhee demonstrates its ubiquity in animals, both herbivore and carnivore; in plants; in ecosystems; in molecules, including DNA, proteins, and enzymes; and even in minds, describing problem-solving behavior and group behavior as the products of convergence. For each species example, he provides an abbreviated list of the major nodes in its phylogenetic classification, allowing the reader to see the evolutionary relationship of a group of species that have independently evolved a similar trait by convergent evolution. McGhee analyzes the role of functional and developmental constraints in producing convergent evolution, and considers the scientific and philosophical implications of convergent evolution for the predictability of the evolutionary process.
Download or read book The Common Marmoset in Captivity and Biomedical Research written by Robert P. Marini and published by Academic Press. This book was released on 2018-11-19 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Common Marmoset in Captivity and Biomedical Research is the first text dedicated exclusively to this species,filling an urgent need for an encyclopedic compilation of the existing information. Sponsored by the AmericanCollege of Laboratory Animal Medicine as part of its authoritative Blue Book series, the book covers the biology,management, diseases, and clinical and research applications of this important species. The common marmoset(Callithrix jacchus) has come of age in the scientific community as a behaviorally complex, cognitively advanced,small, prolific, and easily maintained nonhuman primate with many of the advantages of larger animals, such asmacaques, but without the attendant physical and zoonotic risks. Marmosets are currently being used in diverse areas of inquiry, including vision and auditory research, infectious disease, cognitive neuroscience, behavior, reproductive biology, toxicology and drug development, and aging. Themarmoset genome has been sequenced and there is currently an intensive effort to apply gene editing technologies to the species. The creation of transgenic marmosets will provide researchers with a small nonhuman primatemodel to study a number of poorly understood disorders, like autism. Presents a complete view of the marmoset, covering their biology and management, diseases and clinical applications, and research applications Includes contributions from renowned and international authors and editors Provides the first authoritative and comprehensive treatment of marmosets in biomedical research as part of the ACLAM Series
Download or read book Placental Bed Disorders written by Robert Pijnenborg and published by Cambridge University Press. This book was released on 2010-06-03 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now recognized that defective placentation in the human is a cause of many pregnancy complications, such as spontaneous abortion, preterm labor and delivery, pre-eclampsia, intrauterine growth restriction, fetal death and abruptio placenta. These clinical disorders can often have long-term consequences into adulthood, causing cardiovascular disease, obesity and diabetes for the newborn as well as an increased risk of premature death in the mother. This is the first book to be entirely focused on the placental bed, bringing together the results of basic and clinical research in cell biology, immunology, endocrinology, pathology, genetics and imaging to consolidate in a single, informative source for investigators and clinicians. Its core aim is to explore new approaches and improve current clinical practice. This is essential reading for clinicians in obstetric, cardiovascular and reproductive medicine.
Download or read book Recent Advances in T Cell Biology New Ligands New Functions and New Translational Perspectives written by Dieter Kabelitz and published by Frontiers Media SA. This book was released on 2016-02-16 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gamma/delta (γδ) T-cells are a small subset of T-lymphocytes in the peripheral circulation but constitute a major T-cell population at other anatomical localizations such as the epithelial tissues. In contrast to conventional α/β T-cells, the available number of germline genes coding for T-cell receptor (TCR) variable elements of γδ T-cells is very small. Moreover, there is a prefential localization of γδ T-cells expressing given Vgamma and Vdelta genes in certain tissues. In humans, γδ T-cells expressing the Vg9Vd2-encoded TCR account for anywhere between 50 and >95% of peripheral blood γδ T-cells, whereas cells expressing non-Vd2 genes dominate in mucosal tissues. In mice, there is an ordered appearance of γδ T-cell „waves“ during embryonic development, resulting in preferential localization of γδ T-cells expressing distinct VgammaVdelta genes in the skin, the reproductive organs, or gut epithelia. The major function of γδ T-cells resides in local immunosurveillance and immune defense against infection and malignancy. This is supported by the identification of ligands that are selectively recognized by the γδ TCR. As an example, human Vgamma9Vdelta2 T-cells recognize phosphorylated metabolites („phosphoantigens“) that are secreted by many pathogens but can also be overproduced by tumor cells, providing a basis for a role of these γδ T-cells in both anti-infective and anti-tumor immunity. Similarly, the recognition of endothelial protein C receptor by human non-Vdelta2 γδ T-cells has recently been identified to provide a link for the role for such γδ T-cells in immunity against epithelial tumor cells and cytomegalovirus-infected endothelial cells. In addition to „classical“ functions such as cytokine production and cytotoxicity, recent studies suggest that subsets of γδ T-cells can exert additional functions such as regulatory activity and – quite surpisingly – „professional“ antigen-presenting capacity. It is currently not well known how this tremendous extent of functional plasticity is regulated and what is the extent of γδ TCR ligand diversity. Due to their non-MHC-restricted recognition of unusual stress-associated ligands, γδ T-cells have raised great interest as to their potential translational application in cell-based immunotherapy. Topics of this Research Focus include: Molecular insights into the activation and differentiation requirements of γδ T-cells, role of pyrophosphates and butyrophilin molecules for the activation of human γδ T-cells, role of γδ T-cells in tumor immunity and in other infectious and non-infectious diseases, and many others. We are most grateful to all colleagues who agreed to write a manuscript. Thanks to their contributions, this E-book presents an up-to-date overview on many facets of the still exciting γδ T-cells.

Download or read book Building Babies written by Kathryn B.H. Clancy and published by Springer Science & Business Media. This book was released on 2012-08-27 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ontogeny of each individual contributes to the physical, physiological, cognitive, neurobiological, and behavioral capacity to manage the complex social relationships and diverse foraging tasks that characterize the primate order. For these reasons Building Babies explores the dynamic multigenerational processes of primate development. The book is organized thematically along the developmental trajectory:conception, pregnancy, lactation, the mother-infant dyad, broader social relationships, and transitions to independence. In this volume, the authors showcase the myriad approaches to understanding primate developmental trajectories from both proximate and ultimate perspectives. These collected chapters provide insights from experimental manipulations in captive settings to long-term observations of wild-living populations and consider levels of analysis from molecule to organism to social group to taxon. Strepsirrhines, New World monkeys, Old World monkeys, apes, and humans are all well-represented. Contributions by anthropologists, microbiologists, psychologists, population geneticists, and other primate experts provide Building Babies a uniquely diverse voice. Building Babies features multi- and trans-disciplinary research approaches to primate developmental trajectories and is particularly useful for researchers and instructors in anthropology, animal behavior, psychology, and evolutionary biology. This book also serves as a supplement to upper-level undergraduate courses or graduate seminars on primate life history and development. In these contexts, the book provides exposure to a wide range of methodological and theoretical perspectives on developmental trajectories and models how researchers might productively integrate such approaches into their own work.
