This book was released on 2012-12-06 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: A knowledge, which is as accurate as possible of microbial ecology is indispensible for ecosystem research and environmental protection. This is particularly true for coastal waters, whereby brackish water areas occupy a special position. After several years of preliminary studies on the composition and distribution of the micro flora -algae, fungi, and bacteria -a comprehensive investigation on the primary production, bacterial development and microbial uptake and decom position of substances in the Kie1 Bight was carried out, during which ten scientists from the Institut fUr Meereskunde ofKiel University participated. Here forthe first time numerous hydrographical, chemical and microbiological parameters could be measured on the same water samples. The aim of this joint project was to gain an insight into the manifold functions of the microorganisms in the uptake and degradation of organic substances and in the connections between pollution, production, and remineralization. The results ofthe investigations led not only to new knowledge of the role ofthe microorganisms in the brackish water ecosystem, but also to a revision of earlier conceptions, especially on the influence of wastes on the micro flora and its role in the self-purification of coastal waters. Such a time-limited investigation, however, cannot clarify all the questions on the complex relationships between the microorganisms and their biotope. Therefore, the present volume should also be understood as a stimulus for new and further-reaching research on the microbial ecology of coastal waters. Thereby the most important methods are described, as well as the practical experience obtained.

This book was released on 2019-11-09 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biology and Physiology of Freshwater Neotropical Fish is the all-inclusive guide to fish species prevalent in the neotropical realm. It provides the most updated systematics, classification, anatomical, behavioral, genetic, and functioning systems information on freshwater neotropical fish species. This book begins by analyzing the differences in phylogeny, anatomy, and behaviour of neotropical fish. Systems such as cardiovascular, respiratory, renal, digestive, reproductive, muscular, and endocrine are described in detail. This book also looks at the effects of stress on fish immune systems, and how color and pigmentation play into physiology and species differentiation. Biology and Physiology of Freshwater Neotropical Fish is a must-have for fish biologists and zoologists. Students in zoology, ichthyology, and fish farming will also find this book useful for its coverage of some of the world’s rarest and least-known fish species.

This book was released on 2012-12-06 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerous papers have been published on the animal and algal communities of fresh-water and marine biotopes, and their relation to the physical and chemical factors of their environment. Brackish-water biotopes have been studied much less intensely, presumably due to their limited distribution and to the complexity of their bioco enoses, composed of fresh-water, brackish-water and marine organisms. The reduced size of the species present forms a supplementary difficulty, which is especially pronounced in the algal communities, a major part of which are composed of nanno-phytoplankters. The University of Ghent considered a detailed survey sufficiently attractive to set up because of the high species diversity, the gaps in the knowledge of brackish-water nannophytoplankton at the species and population levels, and the convenient proximity of brackish-water biotopes. Moreover, the brackish-water biotopes proved to be unique, and consist of a series of landlocked creeks, con nected to the sea by means of an underground salt water supply.

Book excerpt: Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.

Available in PDF, EPUB and Kindle. Book excerpt: This book relates some fundamental aspects of biological oceanography and freshwater biology to global aspects of the future protein nutrition of man and to our understanding of the processes of evolution. Seasonal and other factors controlling organic productivity in temperate oceans are outlined, and more unusual trophic features are considered. Methods for future exploitation of the oceans--particularly through sea-farming--are discussed and critically assessed. The finite nature of the oceans' resources is stressed. Energetics of food chains, the dynamics of exploited fish stocks, and the biogeochemistry of organic cycles are clearly explained and examined.--

Download or read book Biology of Fresh Waters written by P.S. Maitland and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the decade since the first edition of this book was published advances have been made in our knowledge of the fresh waters of the world, espe cially in understanding many of the processes involved in their functioning as systems and in countering the problems created by human activities. New problems too, many of an international nature, have loomed during this period-of which global warming and the acidification offresh waters in many parts of the world are notable examples. In addition, much has now been published concerning the aquatic flora, fauna and ecology of previously poorly known geographic areas, notably Australasia. The second edition of this book is a revision which updates the text in the light of recent advances in our knowledge of freshwater biology. Inevitably, in an elementary volume such as this, the treatment of many of the basic principles and processes remains the same. However, several new sections are included covering a range of topics such as acid deposition and the acidification process, bacterial decomposition and aquaculture. The book includes many new references and suggestions for up-to-date reading in particular topics. The objective of the second edition remains the same as that of the first. It is intended as a basic introduction to the major aspects of freshwater biology at a level suitable for undergraduates. It should also prove useful, as apparently did the first edition,Jo professional workers in related fields, e.g. water engineers and chemists, aquaculturists and planners.
