Available in PDF, EPUB and Kindle. Book excerpt: This book is perhaps the first attempt to comprehensively project the uniqueness of molluscs, covering almost all aspects of reproduction and development from aplacophorans to vampyromorphic cephalopods. Molluscs are unique for the presence of protective external shell, defensive inking, geographic distribution from the depth of 9,050 m to an altitude of 4,300 m, gamete diversity, the use of nurse eggs and embryos to accelerate the first few mitotic divisions in embryos, the natural occurrence of androgenics in a couple of bivalves, viable induced tetraploids, gigantism induced by elevated ploidy, the complementary role played by mitochondrial genome in sex determination by nuclear genes and the uptake and accumulation of steroid hormone from surrounding waters. In molluscs, sexuality comprises of gonochorism ( 24%), protandry (

Download or read book Bioaccumulation of Xenobiotic Compounds written by Des W. Connell and published by CRC Press. This book was released on 1989-11-30 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: BIOACCUMULATION of XENOBIOTIC COMPOUNDS is one of the very few - if not only - books written exclusively related to this topic. This book comprehensively outlines the principles governing the accumulation of chemicals from the environment by organisms. Packed with tables and diagrams, this work reviews the experimental data available on both terrestrial and aquatic systems. It describes methods which are used to predict bioaccumulation of chemicals from their physicochemical properties. It also reviews environmental and other factors influencing bioaccumulation. This text also includes previously unpublished theoretical explanations of several bioaccumulation processes, including food chain biomagnification. Information in this exceptional volume is useful to government officials involved with environmental management, chemists, biologists, consultants working with chemical waste control, researchers, and graduate students.

Download or read book Rice in Deep Water written by David Catling and published by Springer. This book was released on 1993-01-14 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rice in Deep Water gives a detailed description of the complex agroecosystem and the growth and development of deepwater rice, a fascinating crop grown by subsistence farmers in the deltas and floodplains of Asia and West Africa flooding to depths of 2-3 metres. An account of the various cultural methods and socioeconomic conditions of the farmers is given, current research efforts to increase productivity discussed and research priorities suggested. The book is designed and profusely illustrated so as to emphasize the complexity and dynamic nature of plant and environment, an aspect so often poorly appreciated and misunderstood.

Download or read book Biological Calcification Cellular and Molecular Aspects written by Harald Schraer 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: The deposition of calcium-containing salts is a widespread phenomenon in both the plant and animal kingdoms. Its occurrence suggests a generalized biological adaptation to environments rich in calcium. Indeed, the Archaean ocean was rich in calcium carbonate, and traces of ancient organisms have been found in lime stones estimated to be about 2. 7 billion years old. The fundamental nature of biological calcification makes it a subject of interest not only to the student of calcium metabolism and skeletal physiology, but also to biologists in general. As in many areas of biological science recent progress in this field has been rapid, and no attempt was made here to cover all the biological systems in which calcifica tion is an important facet of the organisms' method of operation. Calcification is approached in this volume at the levels of the cellular sites and molecular mechan isms that are involved in this process. The ultrastructural and chemical features of the cells and their products which are associated with calcification are empha sized in several chapters. The editor, in inviting contributions from authors, in tended that collectively the chapters should convey a sense of the ubiquitous and essential nature of the role of calcification in several phyla of the plant and animal kingdoms. The researchers were biochemists, physical chemists, cell biologists and physiologists; some represented medicine and dentistry; all were interested in calcification.

Download or read book Memoir II written by A. P. Vinogradov and published by Yale University Press. This book was released on 2018-10-23 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference summarizes and tabulates most of the published knowledge of its time, providing a comprehensive presentation of more than 60 elements found in marine organisms. Extensive data, including 327 tables, on various marine groups from planktonic and nonplanktonic algae through fishes should be particularly valuable to investigators in biochemistry and physiology, geology, chemical oceanography, and nutrition. This edition, translated from the original Russian publications by Julia Efron and Jane K. Setlow, contains additional data and observations, not previously published elsewhere, which were added by Vinogradov in the preparation of the translation. The extensive bibliography of more than 2,000 titles was prepared by Virginia Odum.

Download or read book Aquatic Monocotyledons of North America written by Donald H. Les and published by CRC Press. This book was released on 2020-05-10 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together information on the natural history, ecology and systematics of North American aquatic monocotyledons. The book is an overview of the biology of major aquatic species by compiling information from numerous sources that lie scattered among the primary literature, herbarium databases, and other reference sources. Information on more than 300 species in 87 genera of monocotyledons will be included. Recent phylogenetic analyses will be incorporated. Although focusing specifically on North America, the cosmopolitan distribution of many aquatic plants should make this an attractive text to people working virtually anywhere outside of the region as well. Key Selling Features: The primary source of natural history information on aquatic plants Comprehensive lists of ecological associates Synthetic overview of systematic relationships of aquatic species and genera Practical information for rare and invasive plant managers Essential guide to facilitate wetland delineation
