Book Description
Data on the environmental requirements and pollution tolerance of 300 common species and varieties of fresh water diatoms was compiled from 48 references. The following parameters were considered: pH, nutrients, salinity, organic pollution tolerance (sapobrien system), current, general habitat, specific habitat, seasonal distribution, temperature and geographical distribution. A consensus of opinions for each parameter was established for most taxa. It is suggested that this compilation be employed to evaluate data from plankton and periphyton samples collected for the assessment of water quality.

Book Description
The Llobregat belongs to the most thoroughly studied rivers in Europe and is a paradigm of the confluence of human and natural disturbances in a single basin. Because of its location in a very densely populated region and its Mediterranean character, the Llobregat supports a mixture of irregular flow, water abstraction, excess nutrients, mining debris, and a wide array of pollutants. The aquatic organisms strive to survive in a dramatically changing river that passes through a succession of dams, weirs and channels. The long-term river monitoring as well as the research that has been carried out in the river for a long time have provided an extensive knowledge of these disturbances and their effects on the biological communities. This book highlights the available information, with emphasis on the hydrological, chemical and biological elements interspersed in the river. Experts in the field discuss the main nutrient patterns and pollutant occurrence and the responses of the biological quality elements as well as the river ecosystem to the overall natural and man-made influences.

Book Description
This book is the first to provide an identification key to this important freshwater group of algae which enables the user to work from live specimens. The use of fresh material means that time-consuming preparation techniques can be avoided enabling analyses to be made within a short time of collection. Also the diatoms can be counted, identified and studied at the same time as other algae in the sample. The book provides a general introduction to the diatoms including a resume of the variety of chloroplast forms encountered, a review of colony types, a guide to shape terminology and also information on how to measure cells. The keys are designed for the specialist and the non-specialist alike, allowing two points of entry and the identification of most common taxa to species level. When cleaned material is necessary for unequivocal identification, this is indicated. The book also contains a list of all species included with brief ecological notes on occurrences and distribution along with a glossary of terms. This book will be of immense use to biologists studying algal communities in freshwater ecosystems and particularly to those involved in monitoring programmes. The increasing realization of the importance of algae to the health of aquatic ecosystems, and the developing use of diatoms as environmental indicators means that this volume will become an invaluable aid to the water industries and environmental protection agencies.

Book Description
The content is focused on benthic communities showing how they play an in important role in the river ecosystems. Provides also information on taxonomy of river-inhabiting algal groups, including phylogeny, distribution, collection, preservation and description of the most representative genera of algae in river benthic algal communities. 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.

Book Description
Freshwater Algae: Identification and Use as Bioindicators provides a comprehensive guide to temperate freshwater algae, with additional information on key species in relation to environmental characteristics and implications for aquatic management. The book uniquely combines practical material on techniques and water quality management with basic algal taxonomy and the role of algae as bioindicators. Freshwater Algae: Identification and Use as Bioindicators is divided into two parts. Part I describes techniques for the sampling, measuring and observation of algae and then looks at the role of algae as bioindicators and the implications for aquatic management. Part II provides the identification of major genera and 250 important species. Well illustrated with numerous original illustrations and photographs, this reference work is essential reading for all practitioners and researchers concerned with assessing and managing the aquatic environment.

Book Description
Algae are an important component of aquatic benthic ecosystems because they reflect the health of their environment through their density, abundance, and diversity. This comprehensive and authoritative text is divided into three sections to offer complete coverage of the discussion in this field. The first section introduces the locations of benthic algae in different ecosystems, like streams, large rivers, lakes, and other aquatic habitats. The second section is devoted to the various factors, both biotic and abiotic, that affect benthic freshwater algae. The final section of the book focuses on the role played by algae in a variety of complex freshwater ecosystems. As concern over environmental health escalates, the keystone and pivotal role played by algae is becoming more apparent. This volume in the Aquatic Ecology Series represents an important compilation of the latest research on the crucial niche occupied by algae in aquatic ecosystems. - Presents algae as the important player in relation to environmental health - Prepared by leading authorities in the field - Includes comprehensive treatment of the functions of benthic algae as well as the factors that affect these important aquatic organisms - Acts as an important reference for anyone interested in understanding and managing freshwater ecosystems
