Book Description
Tropical Stream Ecology describes the main features of tropical streams and their ecology. It covers the major physico-chemical features, important processes such as primary production and organic-matter transformation, as well as the main groups of consumers: invertebrates, fishes and other vertebrates. Information on concepts and paradigms developed in north-temperate latitudes and how they do not match the reality of ecosystems further south is expertly addressed. The pressing matter of conservation of tropical streams and their biodiversity is included in almost every chapter, with a final chapter providing a synthesis on conservation issues. For the first time, Tropical Stream Ecology places an important emphasis on viewing research carried out in contributions from international literature. - First synthetic account of the ecology of all types of tropical streams - Covers all of the major tropical regions - Detailed consideration of possible fundamental differences between tropical and temperate stream ecosystems - Threats faced by tropical stream ecosystems and possible conservation actions - Descriptions and synstheses life-histories and breeding patterns of major aquatic consumers (fishes, invertebrates)

Book Description
Nitrogen in the Marine Environment provides information pertinent to the many aspects of the nitrogen cycle. This book presents the advances in ocean productivity research, with emphasis on the role of microbes in nitrogen transformations with excursions to higher trophic levels. Organized into 24 chapters, this book begins with an overview of the abundance and distribution of the various forms of nitrogen in a number of estuaries. This text then provides a comparison of the nitrogen cycling of various ecosystems within the marine environment. Other chapters consider chemical distributions and methodology as an aid to those entering the field. This book discusses as well the enzymology of the initial steps of inorganic nitrogen assimilation. The final chapter deals with the philosophy and application of modeling as an investigative method in basic research on nitrogen dynamics in coastal and open-ocean marine environments. This book is a valuable resource for plant biochemists, microbiologists, aquatic ecologists, and bacteriologists.

Book Description
In 1939, when the electron optics laboratory of Siemens & Halske Inc. began to manufacture the first electron microscopes, the biological and medical profes sions had an unexpected instrument at their disposal which exceeded the reso lution of the light microscope by more than a hundredfold. The immediate and broad application of this new tool was complicated by the overwhelming prob lems inherent in specimen preparation for the investigation of cellular struc tures. The microtechniques applied in light microscopy were no longer appli cable, since even the thinnest paraffin layers could not be penetrated by electrons. Many competent biological and medical research workers expressed their anxiety that objects in high vacuum would be modified due to complete dehydration and the absorbed electron energy would eventually cause degrada tion to rudimentary carbon backbones. It also seemed questionable as to whether it would be possible to prepare thin sections of approximately 0. 5 11m from heterogeneous biological specimens. Thus one was suddenly in posses sion of a completely unique instrument which, when compared with the light microscope, allowed a 10-100-fold higher resolution, yet a suitable preparation methodology was lacking. This sceptical attitude towards the application of electron microscopy in bi ology and medicine was supported simultaneously by the general opinion of colloid chemists, who postulated that in the submicroscopic region of living structures no stable building blocks existed which could be revealed with this apparatus.

Book Description
This dictionary is intended as a guide to the terminology used in a wide range of animal-related programmes of study including agriculture, animal care, animal management, animal production, animal welfare, veterinary nursing, wildlife conservation and zoo biology. In total it contains over 5,300 entries. It contains a wide range of terms used in the fields of veterinary science, physiology and zoology, as students whose primary interests are animal welfare or zoo biology also need to have some understanding of disease, how animal bodies function and how animals are classified. It also contains some legal terms, and reference to some legal cases, to help students understand how the protection, use and conservation of animals is regulated by the law. Some people, famous animals, literature and films have influenced the way we think about, and behave towards, animals. For this reason, the book includes references to important books about animals, famous animals who have starred in films or been the subject of scientific studies, along with short biographies of famous scientists and others who have studied animals or established conservation or animal welfare organisations.
