Drosophila melanogaster, Drosophila simulans: So Similar, So Different
This book brings together most of the information available concerning two species that diverged 2-3 million years ago. The objective was to try to understand why two sibling species so similar in several characteristics can be so different in others. To this end, it was crucial to confront all data from their ecology and biogeography with their behavior and DNA polymorphism. Drosophila melanogaster and Drosophila simulans are among the two sibling species for which a large set of data is available. In this book, ecologists, physiologists, geneticists, behaviorists share their data on the two sibling species, and several scenarios of evolution are put forward to explain their similarities and divergences. This is the first collection of essays of its kind. It is not the final point of the analyses of these two species since several areas remain obscure. However, the recent publication of the complete genome of D. melanogaster opens new fields for research. This will probably help us explain why D. melanogaster and D. simulans are sibling species but false friends.
Genetics of Mate Choice: From Sexual Selection to Sexual Isolation
Genetic studies aimed at understanding the origin of species are dominating major scientific journals. In the past decade, genetic tools that were previously available only in model systems have become accessible to investigators working on nearly all species. Concurrent with these technical advances has been an increase in understanding of both the importance of considering the ecological context of speciation and testing hypotheses about causes for species formation. Many recent studies suggest a prominent role of sexual selection in species formation. These advances have produced a need for a synthesis of what we now understand about speciation, and perhaps more importantly, where we shou...
Organtransplantation in Rats and Mice
Main focus of the new book will be the description and discussion of rat and mouse models for organ transplantation. Various microsurgical techniques will be presented which allow transplantation of functional organs in syngeneic systems. In particular, the extremely difficult methods necessary for organ transplantation in mice will be presented and evaluated. Besides these practical aspects the book will also cover the theoretical sides of organ transplantation like the immunobiology of allotransplantation. Special emphasis will be given to the resurgent field of xenotransplantation. The results from xenograft models developed in the recent years using rats or mice will be reviewed and their impact on future human xenotransplantation will be discussed.
Immunobiology of Organ Transplantation
Currently, individuals interested in seeking an in-depth discussion of transplantation immunology must seek individual articles published in several journals, or extrapolate information from various non-transplant immunology textbooks. The purpose of this text is to provide the reader with a single source of information for the basic science of immunobiology of organ transplantation. It is unique that it focuses on immunobiology from the basic research side, with an emphasis on the cellular and molecular levels. The readers will be physicians, scientists, and graduate students interested and engaged in the study of immunology as it relates to allo- and xenotransplantation. This book is designed to be the reference standard for the immunobiology of transplantation.
Transposable Elements and Genome Evolution
Once considered merely `selfish' or `parasitic' DNA, transposable elements are today recognized as being of major biological significance. Not only are these elements a major source of mutation, they have contributed both directly and indirectly to the evolution of genome structure and function. On October 8-10, 1999, 100 molecular biologists and evolutionists representing 11 countries met on the campus of The University of Georgia in Athens for the inaugural Georgia Genetics Symposium. The topics of presentations ranged from how the elements themselves have evolved to the impact transposable elements have had on the evolution of their host genomes. The papers in this volume therefore represent state-of-the-art thinking, by leading world experts in the field, on the evolutionary significance of transposable elements.
