Research activity involving algae in the classes Chrysophyceae and Synurophyceae ('chrysophytes') has increased dramatically over the last decade. These beautiful and delicate organisms are pivotal for studies of protistan evolution, food web dynamics in oligotrophic freshwater ecosystems, and for the assessment of environmental degradation resulting from eutrophication and acid rain. They also represent excellent model cellular systems for studying processes inherent in basic metabolism, biomineralization, endo- and exo-cytosis and macro-assembly of cell surface layers. This book gives a broad overview of current research, emphasizing the phylogeny, ecology and development of these organisms. Each chapter also contains reviews of the literature, and presents ideas for future research. Phycologists, palaeoecologists, limnologists and plankton ecologists will find this a mine of invaluable information.

This 1986 book presents an in-depth treatment of the biology of chrysophytes, providing a strong foundation towards understanding today's living forms of chrysophyte algae and illuminating the probable aquatic ecosystems of the past. The papers are from the 1953 First International Chrysophyte Symposium held at the University of North Dakota.

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

This AWWA manual of practice provides water professionals with solutions to algae-related problems. Topics covered include identification of algal species, monitoring programs, and best management and treatment strategies.

AWWA Manual of Water Supply Practice M57 provides all the information required by water treatment professionals to understand and mitigate problems caused by algae in source waters, such as tastes and odors, biofouling, and toxin production. With more than 450 pages and hundreds of photos and illustrations, the manual is a comprehensive reference for identifying and treating algae from drinking water sources.

Recent advances in ultrastructural and molecular research have provided new understandings of relationships of traditional chrysophytes, and also many new genera have been described in the last two decades. In this encyclopedia 201 genera of chrysophytes known to date (plus numerous synonyms) are surveyed, namely 110 genera of Chrysophyceae sensu stricto and 58 additional genera, many of which have previously been accommodated in the Chrysophyceae, but are now placed in other classes of the Chromophyta/Heterokonta [i.e., Synurophyceae (8 genera), Dictyochophyceae (13 genera), Pelagophyceae (10 genera), Phaeothamniophyceae (16 genera) and "Bicosoecophyceae" (11 genera)]. Also treated are 33 insufficiently known genera of uncertain affinity, which probably do not belong to the Chrysophyceae sensu stricto, but which have often been assigned to this class (e.g., among others, genera included in the family Aurosphaeraceae and in the orders Chrysomeridales and Parmales). The concept of classification presented in this book is very different from that in the last detailed monographs on freshwater Chrysophyceae by Bourrelly (1981) and Starmach (1985). We also include information on more than 80 genera which have not yet been treated by these authors. Almost 50 of these are marine and are now mostly classified in the Dictyochophyceae, Pelagophyceae and "Bicosoecophyceae", or belonging to the genera of uncertain chrysophyte affiliation. In comparison with these previous monographs a number of colourless flagellates (e.g., the choanoflagellates that were included in the Chrysophyceae as a separate subclass, Craspedomonadophycidae), have been taken away from this class, since they were shown to be related to different protistan lineages with no close relationships to heterokonts. This volume is the result of an ambitious project, entitled "Encyclopedia of Algal genera" launched back in 1988 by Bruce Parker and sponsored by the Phycological Society of America. A large team of coeditors and contributors was set down, so that all groups of algae could be covered. After some years, however, the project ran into difficulties and it became increasingly clear that it could not be completed so that in 1999 it was finally abandoned. The manuscripts, in different states of completeness, were handed over to the Phycological Society of America, who, unfortunately, did not find it possible to continue the project and bring it to conclusion (publication). The chrysophyte manuscripts, however, were almost complete and newly revised, and we found that all our work, together with that of the other chrysophyte contributors, should not be wasted, but published as a separate chrysophyte encyclopedia in Bibliotheca Phycologica. The editors and contributors thank PSA who supported the idea and gave the necessary permissions.

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
