The book also approaches the ecology of river algae not to mention the ecological factors influencing abundance, distribution and diversity of river benthic algal communities and their use as bio-indicators, providing an up-to-date information on taxonomy, ecology, methodology and uses, and a great source of research to everyone interested in freshwater algae, limnology, water quality assessment and biodiversity in river ecosystems.

Freshwater Algae of North America: Ecology and Classification, Second Edition is an authoritative and practical treatise on the classification, biodiversity, and ecology of all known genera of freshwater algae from North America. The book provides essential taxonomic and ecological information about one of the most diverse and ubiquitous groups of organisms on earth. This single volume brings together experts on all the groups of algae that occur in fresh waters (also soils, snow, and extreme inland environments). In the decade since the first edition, there has been an explosion of new information on the classification, ecology, and biogeography of many groups of algae, with the use of molecular techniques and renewed interest in biological diversity. Accordingly, this new edition covers updated classification information of most algal groups and the reassignment of many genera and species, as well as new research on harmful algal blooms. - Extensive and complete - Describes every genus of freshwater algae known from North America, with an analytical dichotomous key, descriptions of diagnostic features, and at least one image of every genus. - Full-color images throughout provide superb visual examples of freshwater algae - Updated Environmental Issues and Classifications, including new information on harmful algal blooms (HAB) - Fully revised introductory chapters, including new topics on biodiversity, and taste and odor problems - Updated to reflect the rapid advances in algal classification and taxonomy due to the widespread use of DNA technologies

Algae Abstracts is the first in a series of bibliographies on water re sources and pollution published by IFI/ Plenum Data Corporation in cooperation with the Water Resources Scientific Information Center (WRSIC). It is produced wholly from the information base compris ing material abstracted and indexed for Selected Water Resources Abstracts. The bibliography is divided into volumes according to the publication dates of the source documents. Volume 1 contains 569 abstracts cov ering publication dates up to and including 1969; Volume 2 contains 730 abstracts covering the years 1970 to 1972. The material included in this bibliography represents computer selections based on the presence of a form of the word "alga" somewhere in the referenced citation. Substantively, the material typifies WRSIC's "centers of com petence" approach to information support of the Office of Water Re sources Research (OWRR) of the Department of the Interior. Most of the references in this bibliography are the work of the center of competence on eutrophication at the University of Wisconsin. The indexes refer to the WRSIC accession number, which follows each abstract. The Significant Descriptor Index is made up of a fraction of the total descriptors and identifiers by which each paper has been indexed. It represents weighted terms that best describe the informa tion content; this status is indicated by the asterisks which precede them. The General Index includes all the remaining descriptors and identifiers by which each paper in this bibliography has been indexed.

This is the second edition of Freshwater Algae; thepopular guide to temperate freshwater algae. This book uniquelycombines practical information on sampling and experimentaltechniques with an explanation of basic algal taxonomy plus a keyto identify the more frequently-occurring organisms. Fullyrevised, it describes major bioindicator species in relationto key environmental parameters and their implications for aquaticmanagement. This second edition includes: the same clear writing style as the first edition to provide aneasily accessible source of information on algae within standingand flowing waters, and the problems they may cause the identification of 250 algae using a key based on readilyobservable morphological features that can be readily observedunder a conventional light microscope up-to-date information on the molecular determination of taxonomicstatus, analytical microtechniques and the potential role ofcomputer analysis in algal biology upgrades to numerous line drawings to include more detail and extraspecies information, full colour photographs of live algae –including many new images from the USA and China Bridging the gap between simple identification texts and highlyspecialised research volumes, this book is used both as a comprehensive introduction to the subject and as alaboratory manual. The new edition will be invaluable to aquaticbiologists for algal identification, and for all practitioners andresearchers working within aquatic microbiology in industry andacademia.

When Biology of the Red Algae was first published in 1990, it was the first comprehensive monograph to be written on the Rhodophyta in over fifteen years. This book presents an authoritative review on the state of knowledge on the biology of the red algae. Written by a group of 26 internationally renowned experts, the eighteen chapters of Biology of the Red Algae range from molecular and cellular to biochemical, physiological, organismal, and ecological aspects of this important group of algae. Together they will be of interest for students of oceanography and plant evolution.

This book looks at the actual habitats in which algae occur. The communities of the individual habitats such as open water, sediments, rocky shores, coral reefs, hot springs, sea ice, soil, etc., are then discussed with special phenomena highlighted, for example rhythmic activity, nitrogen fixation and buoyancy.

Rivers of North America, Second Edition features new updates on rivers included in the first edition, as well as brand new information on additional rivers. This new edition expands the knowledge base, providing readers with a broader comparative approach to understand both the common and distinct attributes of river networks. The first edition addressed the three primary disciplines of river science: hydrology, geomorphology, and ecology. This new edition expands upon the interactive nature of these disciplines, showing how they define the organization of a riverine landscape and its processes. An essential resource for river scientists working in ecology, hydrology, and geomorphology. - Provides a single source of information on North America's major rivers - Features authoritative information on more than 200 rivers from regional specialists - Includes full-color photographs and topographical maps to illustrate the beauty, major features, and uniqueness of each river system - Offers one-page summaries help readers quickly find key statistics and make comparisons among rivers

The main objective of the Water Framework Directive in the European countries is to achieve a “good status” of all the water bodies, in the integrated management of river basins. In order to assess the impact of improvement measures, water quality models are necessary. During the previous decades the progress in computer technology and computational methods has supported the development of advanced mathematical models for pollutant transport in rivers and streams. This book is intended to provide the fundamental knowledge needed for a deeper understanding of these models and the development of new ones, which will fulfil future quality requirements in water resources management. This book focuses on the fundamentals of computational techniques required in water quality modelling. Advection, dispersion and concentrated sources or sinks of contaminants lead to the formulation of the fundamental differential equation of pollutant transport. Its integration, according to appropriate initial and boundary conditions and with the knowledge of the velocity field, allows for pollutant behaviour to be assessed in the entire water body. An analytical integration is convenient only in one-dimensional approach with considerable simplification. Integration in the numerical field is useful for taking into account particular aspects of water body and pollutants. To ensure their reliability, the models require accurate calibration and validation, based on proper data, taken from direct measurements. In addition, sensitivity and uncertainty analysis are also of utmost importance. All the above items are discussed in detail in the 21 chapters of the book, which is written in a didactic form for professionals and students.
