This book was released on 2011-04-01 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Wrong Place: Alien Marine Crustaceans - Distribution, Biology And Impacts provides a unique view into the remarkable story of how shrimps, crabs, and lobsters – and their many relatives – have been distributed around the world by human activity, and the profound implications of this global reorganization of biodiversity for marine conservation biology. Many crustaceans form the base of marine food chains, and are often prominent predators and competitors acting as ecological engineers in marine ecosystems. Commencing in the 1800s global commerce began to move hundreds – perhaps thousands – of species of marine crustaceans across oceans and between continents, both intentionally and unintentionally. This book tells the story of these invasions from Arctic waters to tropical shores, highlighting not only the importance and impact of all prominent crustacean invasions in the world's oceans, but also the commercial exploitation of invasive crabs and shrimps. Topics explored for the first time in one volume include the historical roots of man's impact on crustacean biogeography, the global dispersal of crabs, barnacle invasions, insights into the potential scale of tropical invasions, the history of the world's most widely cultured shrimp, the invasive history and management of red king crabs in Norway, Chinese mitten crabs in England, and American blue crabs in Europe, the evolutionary ecology of green crabs, and many other subjects as well, touching upon all ocean shores.
Download or read book The Ecology of Marine Fishes written by Dr. Larry G. Allen and published by Univ of California Press. This book was released on 2006-02-15 with total page 1353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine fishes have been intensively studied, and some of the fundamental ideas in the science of marine ecology have emerged from the body of knowledge derived from this diverse group of organisms. This unique, authoritative, and accessible reference, compiled by 35 luminary ecologists, evolutionary biologists, and ichthyologists, provides a synthesis and interpretation of the large, often daunting, body of information on the ecology of marine fishes. The focus is on the fauna of the eastern Pacific, especially the fishes of the California coast, a group among the most diverse and best studied of all marine ecosystems. A generously illustrated and comprehensive source of information, this volume will also be an important launching pad for future research and will shed new light on the study of marine fish ecology worldwide. The contributors touch on many fields in biology, including physiology, development, genetics, behavior, ecology, and evolution. The book includes sections on the history of research, both published and unpublished data, sections on collecting techniques, and references to important earlier studies.

Available in PDF, EPUB and Kindle. Book excerpt: This book is openly available in digital formats thanks to a generous grant from the Andrew W. Mellon Foundation. The Atlantic-Pacific Central American sea-level canal is generally regarded as a spectacular failure. However, Deep Cut examines the canal in an alternative context, as an anticipated infrastructure project that captured attention from the nineteenth through the late twentieth centuries. Its advocates included naturalist Alexander von Humboldt, physicist Edward Teller, and U.S. presidents John F. Kennedy, Lyndon Johnson, and Jimmy Carter. The waterway did not come to fruition, but as a proposal it served important political and scientific purposes during different eras, especially the years spanning the Cold War and the “environmental decade” of the 1970s. Historian Christine Keiner shows how the evolving plans for the sea-level ship canal performed distinct kinds of work for diverse historical actors in light of shifting scientific, environmental, and diplomatic values. Dismissing it as a failed scheme prevents us from considering the political, cultural, and epistemological processes that went into constructing the seaway as an innovative diplomatic solution to rising U.S.-Panama tensions, an exciting research opportunity for evolutionary biologists, a superior hydrocarbon highway for the oil industry, or a serious ecological threat to marine biodiversity. Invoking past dreams and nightmares of peaceful nuclear explosives, invasive sea snakes, and the 1970s energy crisis, Deep Cut uses the Central American seaway proposal to examine the changing roles of environmental diplomacy and state-sponsored environmental impact assessment. More broadly, Keiner amplifies an emerging conversation around the environmental, scientific, and political histories and legacies of unrealized megaprojects.

Available in PDF, EPUB and Kindle. Book excerpt: An Introduction to Numerical Classification describes the rationale of numerical analyses by means of geometrical models or worked examples without possible extensive algebraic symbolism. Organized into 13 chapters, the book covers both the taxonomic and ecological aspects of numerical classification. After briefly presenting different terminologies used in this work, the book examines several types of biological classification, including classification by structure, proximity, similarity, and difference. It then describes various ecological and taxonomic data manipulations, such as data reduction, transformation, and standardization. Other chapters deal with the criteria for best computer classification and the complexities and difficulties in this classification. These difficulties are illustrated by reference to studies of the ""bottom communities"" of benthic marine invertebrates, ranging across the entire field from the sampling program and nature of the data to problems over the type of computer used. The concluding chapters consider some of the measures of diversity and the interpretations which have been made from them, as well as the relationship of diversity to classification. The concept and application in biological classification of various multivariate analyses are also discussed in these texts. Supplemental texts on the information measures, partitioning, and interdependence of data diversity are also provided. This book is of value to biologists and researchers who are interested in basic biological numerical classification.

Download or read book The Great American Biotic Interchange written by Francis G. Stehli and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two rather different elements combine to explain the origin of this volume: one scientific and one personal. The broader of the two is the scientific basis-the time for such a volume had arrived. Geology had made remarkable progress toward an understanding of the phys ical history of the Caribbean Basin for the last 100 million years or so. On the biological side, many new discoveries had elucidated the distributional history of terrestrial orga nisms in and between the two Americas. Geological and biological data had been combined to yield the timing of important events with unprecedented resolution. Clearly, when each of two broad disciplines is making notable advances and when each provides new insights for the other, the rewards of cross-disciplinary contacts increase exponentially. The present volume represents an attempt to bring together a group of geologists, paleontologists and biologists capable of exploiting this opportunity through presentation of an interdisciplinary synthesis of evidence and hypothesis concerning interamerican connections during the Cretaceous and Cenozoic. Advances in plate tectonics form the basis for a modern synthesis and, in the broadest terms, dictate the framework within which the past and present distributions of organisms must be interpreted. Any scientific dis cipline must seek tests of its conclusions from data outside of its own confines.

Download or read book Evolution and Environment in Tropical America written by Jeremy B. C. Jackson and published by University of Chicago Press. This book was released on 1996-12-15 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: How were the tropical Americas formed? This ambitious volume draws on extensive, multidisciplinary research to develop new views of the geological formation of the isthmus linking North and South America and of the major environmental changes that reshaped the Neotropics to create its present-day marine and terrestrial ecosystems. Recent discoveries show that dramatic changes in climate and ocean circulation can occur very quickly, and that ecological communities respond just as rapidly. Abrupt changes in the composition of fossil assemblages, formerly dismissed as artifacts of a poor fossil record, now are seen as accurate records of swift changes in the composition of ocean communities. The twenty-four contributors use current work in paleontology, geology, oceanography, anthropology, ecology, and evolution to paint this challenging portrait of rapid environmental and evolutionary change. Their conclusions argue for a revision of existing interpretations of the fossil record and the processes—including invading Eurasian peoples—that have produced it.
