Available in PDF, EPUB and Kindle. Book excerpt: From the lush forests of Appalachia to the frozen tundra of Alaska, and from the tallgrass prairies of the Midwest to the subtropical rainforests of Hawaii, the United States harbors a remarkable array of ecosystems. These ecosystems in turn sustain an exceptional variety of plant and animal life. For species such as salamanders and freshwater turtles, the United States ranks as the global center of diversity. Among the nation's other unique biological features are California's coast redwoods, the world's tallest trees, and Nevada's Devils Hole pupfish, which survives in a single ten-by-seventy-foot desert pool, the smallest range of any vertebrate animal. Precious Heritage draws together for the first time a quarter century of information on U.S. biodiversity developed by natural heritage programs from across the country. This richly illustrated volume not only documents those aspects of U.S. biodiversity that are particularly noteworthy, but also considers how our species and ecosystems are faring, what is threatening them, and what is needed to protect the nation's remaining natural inheritance. Above all, Precious Heritage is a celebration of the extraordinary biological diversity of the United States.

Book excerpt: In recent years, many members of the intellectual community have embraced a radical relativism regarding knowledge in general and scientific knowledge in particular, holding that Kuhn, Quine, and Feyerabend have knocked the traditional picture of scientific knowledge into a cocked hat. Is philosophy of science, or mistaken impressions of it, responsible for the rise of relativism? In this book, Laudan offers a trenchant, wide-ranging critique of cognitive relativism and a thorough introduction to major issues in the philosophy of knowledge.

Book excerpt: I wrote this book because I believe that the welfare of animals is a very important subject but one about which there is a of confusion and muddled thinking. I wanted to great deal write a book which straightened out some of the confusion by looking in detail at one particular problem: how to recognize animal suffering. The book is written for anyone interested in animals and the controversies over how human beings should treat them. I have tried to convince people who might otherwise feel that science had only a rather sinister connection with animal welfare that the scientific study of animal suffering has, in fact, a major and positive contribution to make. It can give us an insight into what animals experience and this, in tum, may help us to alleviate their suffering. At the same time, I have tried to write a book that will be of at least some use to scientists. The chapters which follow pro vide an outline of the biological approach to animal welfare. I have also attempted to show sceptics that it is possible to study animal suffering without sacrificing standards of scien tific procedure. Perhaps some may even come to share my belief that the study of the subjective experiences of animals is one of the most fascinating areas in the whole of biology, as well as being of great practical and ethical importance.

Book excerpt: Latin America is one of the most diverse but also vulnerable regions in the world that is under continuous anthropogenic pressure due to increasing urban, industrial and agricultural developments. Although there are many research groups studying the impacts caused by those pressures, the results and conclusions obtained by many of them are largely unknown because their studies are mostly published at the local or regional scale. Ecotoxicology in Latin America represents an effort to collect and share research performed in Latin America in the area of ecotoxicology and environmental risk assessment, presenting a collection of relevant and innovative studies focused on the following topics: (i) Contaminant entrance, transportation, distribution and fate; (ii) Environmental risk in freshwater ecosystems; (iii) Ecological risk in coastal zones; (iv) Biomonitoring programs: water, sediment and air; (v) Physiological effects and biomarkers; (vi) Soil ecotoxicology; (vii) Bioaccumulation and human risk; (viii) Toxicity of emerging contaminants; and (ix) Frontiers in Ecotoxicology. This selection of topics aims at covering the most important subjects and applications of ecotoxicology, including classical and novel subjects. Therefore, this book contains chapters related to different environmental compartments prone to contamination (water, sediment, soil and air), to different contamination sources (agriculture, industry, urban discharges and natural emissions), and to multiple biological responses at different organizational levels (individual to ecosystems, including human beings). It is envisioned to have an international projection within and beyond Latin American countries, as it is a great opportunity to increase the networks not only among Latin American research teams working on similar subjects, but also with teams from other regions. The idea of this book was to favour the connection among groups to quickly improve the development of methods and their application in ecotoxicological and environmental risk studies in Latin America. This book will be useful to important sectors of environmental sciences and related areas, and to specific target demographics such as students and researchers acting in environmental studies, and decision-makers (i.e., politicians and environmental organizations). Ecotoxicology in Latin America presents 34 chapters authored by 111 researchers from 12 Latin American countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Cuba, Ecuador, Mexico, Panama, Peru, Uruguay, and Venezuela) and from 6 non-Latin American countries (Austria, Belgium, Italy, Portugal, Spain, and USA).

Book excerpt: The Bacteria: Volume VII: Mechanisms of Adaptation explores the mechanisms of bacterial adaptations and covers topics ranging from bacterial spores, cysts, and stalks to nitrogen fixation, bacterial chemotaxis, bacteriophage growth, and the structure and biosynthesis of bacterial cell walls. The roles of appendages and surface layers in adaptation of bacteria to their environment are also considered, along with cell division in Escherichia coli. This volume is comprised of nine chapters and begins with a discussion on the structure, properties, formation, and regulation of spores, cysts, and stalks in actinomycetes, blue-green bacteria, myxobacteria, Bacillus, Azotobacter, and Caulobacter. The reader is then introduced to the biochemistry, regulation, genetics, and evolution of nitrogen fixing in organisms; the receptors involved in bacterial chemotaxis and the nature of the sensing mechanism; the outer membrane of gram-negative bacteria; and bacterial functions involved in nutrient detection and acquisition. The roles played by organelles and surface layers in the adaptation of bacteria to their environment are also examined. The final chapter deals with the regulation of, and coordination between, the multitude of events involved in cell division in Escherichia coli. This monograph will be a useful resource for microbiologists, bacteriologists, biochemists, and biologists.

This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phytomass and Primary Production of the Various Vegetational Zones and of the Entire Biosphere The biosphere is that thin layer at the earth's surface in which living organisms exist and biological cycling takes place. It includes the upper horizons of the soil in which plants root, the atmosphere near the ground, (insofar as organisms penetrate this space), and all the surface waters. More than 99% of the earth's biomass is phytomass, to which we shall limit our discussion. Amounts of phytomass are distinctly related to vegeta tional zones. Because accurate determination of phytomass and primary production is difficult, only gross estimates have been available until recently. However, in 1970, Bazilevich et al. published (in Russian) more accurate calculations, based on the rapidly accumulating literature, for the various thermal zones and bioclimatic regions of the earth. These authors calculated mean phyto mass and mean annual primary production for the various regions as dry mass (in tons) per hectare. On the basis of measurements of the areas covered by the individual regions, excluding rivers, lakes, glaciers, and permanent snow, total phytomass and total annual primary production for the various regions were obtained (see table). The sum of these figures is the phytomass and annual production of the land surface of the earth. In addition, the table gives corresponding data for the waters of the earth. The values involved are potential i. e. , they are based on natural vegetation uninfluenced by man.

Available in PDF, EPUB and Kindle. Book excerpt: The first edition of my book "Climate and Circulation of the Tropics" was reasonably up to date to the middle of 1985. In a second printing in 1988 it was possible to complete a few literature references and to correct some misprints. However, vigorous research has taken place over the past five years in various areas of tropical climate dynamics, especially in the atmosphere-ocean mechanisms of climate anomalies, climate prediction, ocean circulation, and paleoclimates. Promising progress has also been made in the application of general circulation modelling to tropical climate problems. In the present second edition, named "Climate Dynamics of the Tropics", I have attempted to incorporate much of the recent work to late 1990. Chapters 8 and 9 have been essentially re-written, and major additions have been made to Chapters 4 and 12 in particular. I would like to acknowledge the continued support by the U.S. National Science Foundation over the past five years. B. Parthasarathy, Poona, and H. Lessmann, San Salvador, sent me updates of data series not easily accessible. I have benefitted from discussions with numerous colleagues in the United States and overseas. In the preparation of this second edition, Marilyn Wolff patiently transferred my illegible hand-written drafts onto word processor. Dierk Polzin and Dan Skemp assisted me with the creation of the page masters and the subject index and Christopher Collimore with the author index.
