Download or read book Intersexuality in the Animal Kingdom written by R. Reinboth and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Richard Goldschmidt' coined the term "intersexuality" in 1915, he intended it to apply to normally dioecious species which exhibit some kind of mixture between male and female characters. However, as knowledge of the bewildering variability present in the sexual orga nization of members of the animal kingdom has increased, the original meaning of the word has changed. Today many authors define inter sexuality as "the presence of both male and female characteristics, or of intermediate sexual characteristics, in a single individual".2 This more extensive and widely accepted concept justifies the title of our book •. Among all the anatomical and physiological features of living organisms the reproductive system has a unique importance for the perpetuation of the species. Conversely, reproductive processes are of little or no account for the viability of the individual. Therefore, within the framework of general biology reproduction has all too often been looked at solely from the point of view of genetics. Lively discussions about genotypic versus phenotypic sex determination long dominated the sci entific literature on sexuality in animals; this one-sided emphasis has tended to obscure many important facets of an organism's ability to reproduce. Recent developments in current biological research have brought the classic problem of sex differentiation into focus again, and the rapid progress being made in comparative endocrinology has added a new di mension to the study of reproductive biology.
Download or read book Plankton Ecology of the Southwestern Atlantic written by Mónica S. Hoffmeyer and published by Springer. This book was released on 2018-06-26 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book integrates a variety of issues such as regional settings of productivity and nutrient cycling; plankton of coastal and shelf systems; plankton, climate change and human-induced changes; harmful algae and their impacts; and gelatinous zooplankton. This book explores the intriguing marine plankton communities of the SWA region of South America encompassing low to high latitude environments, framed by a complex hydrographic background and global climate change. This vast and iconic region has been largely under-recognized and under-studied. However, in recent years a strong interest has emerged along with the acknowledgment of its high biological productivity. The book concludes by discussing conservation in the region, highlighting regional biodiversity hotspots where the challenges of climate change, habitat loss, and other threats to biodiversity may be particularly acute. Plankton Ecology of the Southwestern Atlantic is a timely synthesis of the field, setting a new baseline for future research. It will be important reading for both researchers and graduate students, and will also be of interest and use to a professional audience of oceanographers, conservation biologists, stake holders and educated science enthusiasts
Download or read book The Biology of Nematocysts written by Howard Lenhoff and published by Elsevier. This book was released on 2012-12-02 with total page 613 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Biology of Nematocysts is derived from a symposium dedicated to the exclusive discussion on the biology of nematocysts and cnidocytes. This book is basically a collection of the submitted reviews of contributors and research proceedings presented at the symposium. An introduction on the recognition and discovery of both cnidarians and nematocyst aptly begins the discussion in the book. The first chapter serves as an advanced reading that helps readers be familiarized with the terms used in the entire volume. The following chapters are subdivided into six parts, including topics on the ultrastructure, development, control and morphodynamics of discharge, biochemistry, and natural history. The multidisciplinary approach of the main themes is intended to fully understand the unique qualities of the intracellular structure of nematocyst. This volume will be of great benefit to students and researchers in biological science, cell biology, zoology, microbiology, and general physiology.
Download or read book Coelenterate Biology written by Leonard Muscatine and published by Elsevier. This book was released on 2012-12-02 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coelenterate Biology: Reviews and New Perspectives highlights research areas in which coelenterates are exceptionally useful and interesting experimental animals. It outlines the state of knowledge in coelenterate research and draws attention to some of the challenging problems that are amenable for study. Coelenterates offer valuable material for many levels of inquiry—from the population and organismic to the cellular, subcellular, and molecular levels. They are especially attractive animals for studies in developmental biology and behavior. The book begins by discussing cnidarians histology, focusing on the light and electron microscopy of cnidarian tissues. There are separate chapters on the skeletal system of cnidarians; the morphology, functions, and chemistry of nematocytes; and a few aspects of the enormous subject of cnidarian development. The subsequent chapters deal with cnidarian neurobiology, behavior, locomotion, flotation, and dispersal; experimental studies on algae-cnidarian symbioses; and coelenterate bioluminescence. The book concludes with a discussion of the systems of coordination and nervous system of ctenophores.

Download or read book Seafaring Scientist written by Lester D. Stephens and published by Univ of South Carolina Press. This book was released on 2006 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infused with a sense of adventure and zeal for discovery, Seafaring Scientist recounts the achievements of a giant in the field of marine biology. Alfred Goldsborough Mayor (18681922), a Harvard-trained marine biologist and close associate of Alexander Agassiz, founded and directed on behalf of the Carnegie Institution the first tropical marine biological laboratory in the Western hemisphere. Located on Loggerhead Key in the Gulf of Mexico, the Tortugas Laboratory attracted some of America's most brilliant scientists. Mayor himself achieved international prominence in the field of biology for his authoritative work on jellyfishes and coral reefs.
Download or read book The Masterpiece of Nature written by Graham Bell and published by Routledge. This book was released on 2019-11-28 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1982, The Masterpiece of Nature examines sex as representative of the most important challenge to the modern theory of evolution. The book suggests that sex evolved, not as the result of normal Darwinian processes of natural selection, but through competition between populations or species - a hypothesis elsewhere almost universally discredited. The book also discusses the nature of sex and its consequences for the individual and for the population, as well as various other theories of sex. Since the value of these theories is held to reside wholly in their ability to predict the patterns of sexuality observed in nature, the book seeks to provide an extensive review of the circumstances in which sexuality is attenuated or lost throughout the animal kingdom, and these facts are then used to weigh up the merits of the rival theories. This book will be of interest to researchers in the area of genetics, ecology and evolutionary biology.
