Available in PDF, EPUB and Kindle. Book excerpt: a hierarchical structure, a distance measure between oriented curves was developed. To apply the concept of trajectory distance to morphological data, computational formulas for discrete growth trajectories were defined following a simple working example. Pairwise distances among the 8 shape groups were obtained. Relationships among the shape groups established on the basis of trajectory distance indicated taxonomic usefulness of the proposed method.

Available in PDF, EPUB and Kindle. Book excerpt: High-resolution images of phytoplankton cells such as diatoms or desmids, which are useful for monitoring water quality, can now be provided by digital microscopes, facilitating the automated analysis and identification of specimens. Conventional approaches are based on optical microscopy; however, manual image analysis is impractical due to the huge diversity of this group of microalgae and its great morphological plasticity. As such, there is a need for automated recognition techniques for diagnostic tools (e.g. environmental monitoring networks, early warning systems) to improve the management of water resources and decision-making processes. Describing the entire workflow of a bioindicator system, from capture, analysis and identification to the determination of quality indices, this book provides insights into the current state-of-the-art in automatic identification systems in microscopy.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents twenty peer-reviewed contributions delineating the full breadth of current diatom-related research in the Earth, atmospheric and biological sciences. The volume is dedicated to Dr. Eugene F. Stoermer, who has worked with most of the contributors to this volume, for his life-long scientific work on a variety of topics, the common thread of which has always been diatoms.

Download or read book The Diatoms written by John P. Smol and published by Cambridge University Press. This book was released on 2010-09-30 with total page 687 pages. Available in PDF, EPUB and Kindle. Book excerpt: This much revised and expanded edition provides a valuable and detailed summary of the many uses of diatoms in a wide range of applications in the environmental and earth sciences. Particular emphasis is placed on the use of diatoms in analysing ecological problems related to climate change, acidification, eutrophication, and other pollution issues. The chapters are divided into sections for easy reference, with separate sections covering indicators in different aquatic environments. A final section explores diatom use in other fields of study such as forensics, oil and gas exploration, nanotechnology, and archaeology. Sixteen new chapters have been added since the first edition, including introductory chapters on diatom biology and the numerical approaches used by diatomists. The extensive glossary has also been expanded and now includes over 1,000 detailed entries, which will help non-specialists to use the book effectively.

Download or read book Shape and Form in Plants and Fungi written by David S. Ingram and published by Academic Press. This book was released on 1994 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shape may be regarded as the external contour of an organism, while form describes the three-dimensional arrangement of the component parts. These are distinct yet interdependent concepts, and both are a consequence of development. The forces and processes which determine shape and form in plants and fungi have fascinated botanists and mycologists for centuries; theories abound, yet real understanding remains elusive. The authors in this volume address these matters from a wide variety of different standpoints. The contributions are not an attempt to cover the entire field, but rather a collection likely to stimulate new thought and intellectual excitement. The strength of the volume lies in its diversity of approach and philosophy. Some important themes arise: the creative tension between the holistic and reductionist approaches to analysis of shape and form; the paucity of information on the internal messages and forces which link genome and phenotype; and the potential of research with unicellular plants and with fungi, where the relative simplicity of the systems for study and the increasing availability of the appropriate analytical tools should lead to major advances in understanding. This volume will prove invaluable as a basis for discussion between plant scientists, ecologists and evolutionary biologists at all levels.

Download or read book Limnological and Engineering Analysis of a Polluted Urban Lake written by Steven W. Effler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 846 pages. Available in PDF, EPUB and Kindle. Book excerpt: Onondaga Lake in Syracuse, New York is a model for the analysis and management of a polluted urban lake. Sometimes referred to as "the most polluted lake in the United States", Onondaga Lake is one of only two lakes for which a federal advisory body has been set up to guide environmental remediation. The recipient of significant municipal effluent and industrial waste for more than a century, Onondaga Lake has been the focus of intensive limnological investigation and extensive remediation efforts. This book is a comprehensive presentation of the scientific knowledge about Onondaga Lake, based on research coordinated by the Upstate Freshwater Institute. Onondaga Lake: Limnology and Environmental Management of a Polluted Urban Lake is the most complete case study of a lake, and will be of interest to water quality scientists, engineers and managers, as well as environmental engineers, modelers, and policymakers.
