Book excerpt: Sperm Biology represents the first analysis of the evolutionary significance of sperm phenotypes and derived sperm traits and the possible selection pressures responsible for sperm-egg coevolution. An understanding of sperm evolution is fast developing and promises to shed light on many topics from basic reproductive biology to the evolutionary process itself as well as the sperm proteome, the sperm genome and the quantitative genetics of sperm. The Editors have identified 15 topics of current interest and biological significance to cover all aspects of this bizarre, fascinating and important subject. It comprises the most comprehensive and up-to-date review of the evolution of sperm and pointers for future research, written by experts in both sperm biology and evolutionary biology. The combination of evolution and sperm is a potent mix, and this is the definitive account. The first review survey of this emerging field Written by experts from a broad array of disciplines from the physiological and biomedical to the ecological and evolutionary Sheds light on the intricacies of reproduction and the coevolution of sperm, egg and reproductive behavior

Download or read book Fish Evolution and Systematics Evidence from Spermatozoa written by Barrie G. M. Jamieson and published by Cambridge University Press. This book was released on 1991-05-23 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this 1991 book, Professor Jamieson masterfully brings together the literature on fish spermatozoa and voluminous work on the evolutionary history of fishes to provide a detailed synthesis of the two fields of fish spermatology and fish systematics. The author begins by considering invertebrate phyla related to the chordates, and goes through the lower chordates and early fishes to the line leading to amphibians and to highest teleosts. His treatment provides a review of fish systematics based on the classical evidence of gross morphology in a cladistic framework and a critical integration of this with information on the degree to which spermatozoa support of conflict with the various hypotheses of relationship. Additionally, Professor Jamieson is joined by Luke K. -P. Leung to give a review of the principles of biological cryopreservation and of the live preservation of fish gametes.
Download or read book Sperm Competition and Its Evolutionary Consequences in the Insects written by Leigh W. Simmons and published by Princeton University Press. This book was released on 2019-12-31 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: One hundred years after Darwin considered how sexual selection shapes the behavioral and morphological characteristics of males for acquiring mates, Parker realized that sexual selection continues after mating through sperm competition. Because females often mate with multiple males before producing offspring, selection favors adaptations that allow males to preempt sperm from previous males and to prevent their own sperm from preemption by future males. Since the 1970s, this area of research has seen exponential growth, and biologists now recognize sperm competition as an evolutionary force that drives such adaptations as mate guarding, genital morphology, and ejaculate chemistry across all animal taxa. The insects have been critical to this research, and they still offer the greatest potential to reveal fully the evolutionary consequences of sperm competition. This book analyzes and extends thirty years of theoretical and empirical work on insect sperm competition. It considers both male and female interests in sperm utilization and the sexual conflict that can arise when these differ. It covers the mechanics of sperm transfer and utilization, morphology, physiology, and behavior. Sperm competition is shown to have dramatic effects on adaptation in the context of reproduction as well as far-reaching ramifications on life-history evolution and speciation. Written by a top researcher in the field, this comprehensive, up-to-date review of the evolutionary causes and consequences of sperm competition in the insects will prove an invaluable reference for students and established researchers in behavioral ecology and evolutionary biology.
Download or read book Insect Morphology and Phylogeny written by Rolf G. Beutel and published by Walter de Gruyter. This book was released on 2013-12-12 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decades a remarkable renaissance has materialized in insect morphology, mainly triggered by the development of new cutting-edge technologies. This is an exciting time for biological synthesis where the mysteries and data derived from genomes can be combined with centuries of data from morphology and development. And, now, more than ever, detailed knowledge of morphology is essential to understanding the evolution of all groups of organisms. In this “age of phylogenomics” researchers rely on morphological data to support molecular findings, test complex evolutionary scenarios, and for placing fossil taxa. This textbook provides an in-depth treatment of the structures and the phylogeny of the megadiverse Hexapoda. The first part presents an up-to-date overview of general insect morphology with detailed drawings, scanning electron micrographs, and 3-D reconstructions. Also included is a chapter covering innovative morphological techniques (e.g., μ-computer tomography, 3-D modeling), brief treatments of insect development and phylogenetic methods, and a comprehensive morphological glossary. The second part is of a modern synthesis of insect systematics that includes taxon-specific morphological information for all Orders. The work is an invaluable reference for students and researchers working in all facets of biology and is a must for evolutionary biologists. A detailed understanding of morphology is essential in unraveling phylogenetic relationships and developing complex evolutionary scenarios. Increasingly researchers in phylogenomics are re/turning to morphological data to support their findings, while the development of new cutting-edge technologies has further increased interest in this growing field. This definitive handbook provides an in-depth treatment of insect morphology. The first part presents an up-to-date overview of insect morphology with detailed drawings, brilliant scanning electron micrographs and 3-D reconstructions as interactive PDFs. This is complemented by a chapter on innovative morphological techniques (e.g., μ-computer tomography, 3-D modeling) and a comprehensive morphological glossary. The second part treats the state of the art in insect systematics and includes taxon-specific morphological information for all orders. Systematics are treated formally, with for example the arguments for relationships (“apomorphies”) always listed explicitly. The work is a useful reference for students and researchers working in different fields of biology and a must for those dealing with insects from an evolutionary perspective.

This book was released on 2013-06-29 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1964, the Fertilization and Gamete Physiology Research Training Program (FERGAP) was established at the Marine Biological Laboratories, Woods Hole, Massachusetts. Over the course of the next 12 years, under the directorship of Dr. Charles B. Metz, FERGAP brought together, trained, and inspired a generation of students in reproductive biology from all over the world. As students of C. B. Metz and as FERGAP trainees, we would like to dedicate this collected work on comparative mammalian fertilization to our teacher and mentor, Dr. Charles B. Metz. Like a number of authors contributing to this volume, we have been struck by the significant impact that C. B. Metz and FERGAP had on the development of students of reproductive biology. Applying both the classical and molecular techniques of cell biology and immunology to problems of gamete biology, Dr. Metz emphasized a comparative and analytical approach that was reflected in his own research on fertilization in Paramecia, sea urchins, frogs, and mammals. It is hoped that this volume will serve to stimulate students to discover the myriad of fascinating research problems in gamete and reproductive biology. Bonnie S. Dunbar Michael G.

Download or read book Morphology Molecules Evolution and Phylogeny in Polychaeta and Related Taxa written by Universität Osnabrück and published by Springer Science & Business Media. This book was released on 2006-03-30 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, evidence has been accumulated which shows that some of the groups formerly regarded as independent "phyla" such as Pogonophora (now recognized as Siboglinidae), Echiura, Myzostomida and perhaps Sipuncula, are most probably nothing else than greatly modified Annelida. The extreme morphological diversity found especially in Polychaeta displays the plasticity of a simple segmented organisation that basically is nothing else but a serial repetition of identical units. Thus, annelids are highly important to our understanding of fundamental questions about morphological and adaptive diversity, as well as clarifying evolutionary changes and phylogenetic relationships. The book aims to summarize our knowledge on Polychaetes polychaetes and their allies and gives an overview of recent advances gained by studies that employed conventional and modern methods plus, increasingly and importantly, the use of molecular markers and computer-assisted kinship analyses. It also reflects the state of art in polychaete sciences and presents new questions and controversies. As such it will significantly influence the direction of research on Polychaeta and their related taxa.

Download or read book The Insect Ovary written by Jürgen Büning and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will give an overview of insect ovaries, showing the diversities and the common traits in egg growth processes. The idea to write this book developed while looking at the flood of information which appeared in the early 1980s on early pattern formation in Drosophila embryos. At this time a significant breakthrough was made in studies of this little fly, combining molecular biological methods with classical and molecular genetics. The answers to questions about early pattern formation raised new questions about the architecture of ovaries and the growth of eggs within these ovaries. However, by concentrating only on Drosophila it is not possible to form an adequate picture of what is going on in insect ovaries, since the enormous diversity found among insects is not considered sufficiently. Almost forgotten, but the first to study the architecture of ovaries, was Alexander Brandt writing in 1878 in aber das Ei und seine Bildungsstaette (On the egg and its organ of development). More than 100 years later, a series of ten books or more would be required to survey all the serious informa tion we have today on insect oogenesis. Thus, this book is a personal selection and personal view on the theme, and the authors must be excused by all those scientists whose papers could not be included. The book briefly describes the ectodemes, i. e.
