Download or read book Detecting Ecological Impacts written by Russell J. Schmitt and published by Academic Press. This book was released on 1996-01-17 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detecting Ecological Impacts: Concepts and Applications in Coastal Habitats focuses on crucial aspects of detecting local and regional impacts that result from human activities. Detection and characterization of ecological impacts require scientific approaches that can reliably separate the effects of a specific anthropogenic activity from those of other processes. This fundamental goal is both technically and operationally challenging. Detecting Ecological Impacts is devoted to the conceptual and technical underpinnings that allow for reliable estimates of ecological effects caused by human activities. An international team of scientists focuses on the development and application of scientific tools appropriate for estimating the magnitude and spatial extent of ecological impacts. The contributors also evaluate our current ability to forecast impacts. Some of the scientific, legal, and administrative constraints that impede these critical tasks also are highlighted. Coastal marine habitats are emphasized, but the lessons and insights have general application to all ecological systems.

Download or read book The Biology of Stentor written by Vance Tartar and published by Elsevier. This book was released on 2013-10-22 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Biology of Stentor summarizes all that has been learned about the biology of a certain group of ciliate protozoa: the stentors. Topics covered range from form and function in Stentor to behavior, fine structure, growth and division, and reorganization. Regeneration is also discussed, along with polarity, metabolism, genetics, and primordium development. This volume is comprised of 20 chapters and begins with a characterization of Stentor, with emphasis on its particular advantages in addressing general problems of biology. The reader is then introduced to form and function in Stentor, particularly S. coeruleus. The following chapters focus on the behavior (food selection, swimming, response to light, etc.) of stentors and the fine points of structure in terms of which this behavior is to be explained and which demonstrate the highly complex and precise achievements of morphogenesis. The remaining chapters explore growth and division in Stentor as well as the course of reorganization and regeneration; development of the oral primordium and how it is activated and inhibited; rate of regeneration in relation to the polar axis; fusion masses of whole stentors; and reconstitution in disarranged stentors. Various species of Stentor are also described, together with the techniques used to study them. The final chapter deals with hypotheses concerning the morphogenesis of ciliates. This book will be of interest to students and practitioners of biology and physiology.
Download or read book Zebra Mussels Biology Impacts and Control written by Thomas F. Nalepa and published by CRC Press. This book was released on 1992-11-24 with total page 848 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction and rapid spread of the zebra mussel in North American waters has caused great concern among industrial and recreational users of these waters. This bivalve mollusk is a biofouler that attaches to any firm substrate (e.g. rocks, piers, water intake pipes, boat hulls) and has already created significant problems for raw water users such as water treatment plants and power plants. Zebra Mussels: Biology, Impacts and Control provides essential information regarding the biology of the zebra mussel in North America and Europe, presents case studies of environmental and industrial impacts, and outlines control strategies. Summary articles detail its life history, origins, and morphology. The book also examines techniques used to culture and maintain this organism in the laboratory. Thirty-two color plates illustrate some of the dramatic problems created by the explosive population growth of this species. Zebra Mussels: Biology, Impacts, and Control is an important resource for ecologists, conservationists, environmental consultants, water quality engineers, regulatory officials, power utilities, and libraries.
Download or read book The Geology of the Everglades and Adjacent Areas written by Edward J. Petuch and published by CRC Press. This book was released on 2007-04-18 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Painting a complete picture of the history of the Everglades, The Geology of the Everglades and Adjacent Areas brings together theperspectives of various geoscientists to provides an overview of the geology, paleontology, and paleoceanography of the Everglades region. It emphasizes the upper 300 m of the geologic framework of the area and gives insight into the local stratigraphy, geomorphology, lithology, and historical geology. Building upon the geologic nomenclature and stratigraphic sequences set down by the Florida Geological Survey, the book includes redefinitions of some previously poorly known formations, the chronological fine-tuning of other poorly known units, and the description of 7 new members. Designed to be a field guide as well as a reference, the book is illustrated with photographs of exposed geologic sections, stratotype localities, collection sites, and details of interesting fossil beds. It contains 124 full-page illustrations with 69 black and white figures, 43 black and white plates of index fossils, and 12 full color plates of simulated space shuttle images of Florida’s ancient seas and coastlines. This text is accompanied by downloadable resources that feature animated maps along with a Power Point presentation of simulated space shuttle imagery of Eocene-to-Holocene Florida. The book is arranged by geologic time, ranging from the late Eocene, Oligocene, Miocene, Pliocene, and Pleistocene to the Holocene. The authors place lithostratigraphic descriptions of the geologic formations and members into this chronological framework, along with the paleogeography of the seas and lakes within which they were deposited. They also emphasize biostratigraphy with over 1000 index fossils listed and over 400 illustrated. The book brings together information previously spread through innumerable publications, saving you the time and effort it would take to assemble and cross-reference multiple sources.

Download or read book Turquoise Mosaics from Mexico written by Colin McEwan and published by Duke University Press. This book was released on 2006 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nine turquoise mosaics from Mexico are some the most striking pieces in the collections of the British Museum. Among the few surviving such artifacts, these exquisite objects include two masks, a shield, a knife, a helmet, a double-headed serpent, a mosaic on a human skull, a jaguar, and an animal head. They all originate from the Mixtec and Aztec civilizations first encountered by Europeans during the Spanish conquest in the early sixteenth century. The mosaics have long excited admiration for their masterful blend of technical skill and artistry and fascination regarding their association with ritual and ceremony. Only recently though, have scientific investigations undertaken by the British Museum dramatically advanced knowledge of the mosaics by characterizing, for the first time, the variety of natural materials that were used to create them. Illustrated with more than 160 color images, this book describes the recent scientific findings about the mosaics in detail, revealing them to be rich repositories of information about ancient Mexico. The materials used to construct the mosaics demonstrate their makers' deep knowledge of the natural world and its resources. The effort that would have been involved in procuring the materials testifies to the mosaics' value and significance in a society imbued with myths and religious beliefs. The British Museum's analyses have provided evidence of the way that the materials were prepared and assembled, the tools used, and the choices that were made by artisans. In addition, by drawing on historical accounts including early codices, as well as recent archaeological discoveries, specialists have learned more about the place of the mosaics in ancient Mexican culture. Filled with information about the religion, art, and natural and cultural history as well as the extraordinary ability of modern science to enable detailed insight into past eras, Turquoise Mosaics from Mexico offers an overview of the production, utilization, and eventual fate of these beautiful and mysterious objects.
