Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book The Physiology of Characean Cells written by Mary J. Beilby and published by Springer Science & Business Media. This book was released on 2013-11-19 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the unique characean experimental system, which provides a simplified model for many aspects of the physiology, transport and electrophysiology of higher plants. The first chapter offers a thorough grounding in the morphology, taxonomy and ecology of Characeae plants. Research on characean detached cells in steady state is summarised in Chapter 2, and Chapter 3 covers characean detached cells subjected to calibrated and mostly abiotic types of stress: touch, wounding, voltage clamp to depolarised and hyperpolarised potential difference levels, osmotic and saline stress. Chapter 4 highlights cytoplasmic streaming, cell-to-cell transport, gravitropism, cell walls and the role of Characeae in phytoremediation. The book is intended for researchers and students using the characean system and will also serve as an invaluable reference resource for electrophysiologists working on higher plants.

Download or read book Dragonfly Nymphs of North America written by Kenneth J. Tennessen and published by Springer. This book was released on 2019-03-11 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is the first of its kind devoted entirely to the dragonfly nymphs of North America north of Mexico, the focus being accurate identification of the 330 species of Anisoptera that occur in the region. Nymphal external morphology is described and illustrated in detail, and all terms needed to navigate the dichotomous keys are defined. Species are tabulated with references that provide the most detailed, accurate descriptions for each; species that are inadequately described are so indicated. The key separating the seven families in the region contains several new characters. The families are then covered separately: Aeshnidae (13 genera), Gomphidae (17 genera), Petaluridae (2 genera), Cordulegastridae (2 genera), Macromiidae (2 genera), Corduliidae (7 genera), and Libellulidae (29 genera). Each family is further characterized, followed by a generic key. A drawing of the habitus and diagnostic details for each genus are provided, along with additional diagnostic remarks and notes on habitat and life cycle; for each genus, a map shows its geographic distribution in North America. Full-grown nymphs of all known species of each genus are keyed and diagnosed; characters that apply to earlier instars are noted. Morphological variation in character states was analyzed in order to assess the reliability of previously utilized characters and to discover new characters. Most of the characters used to distinguish all levels of taxa are illustrated; a total of 702 figures, comprising 1,800 original drawings, along with selected photographs where necessary for clarity, accompany the keys. Measurements of total length, head width, and other variables for each species are provided in tables. Difficulties with past keys and descriptions, including errors, omissions and other shortcomings, are addressed. The importance of nymph characters in helping solve generic and specific distinctions and their role in phylogenetic studies is emphasized. Methods for collecting, rearing, and preserving dragonfly nymphs and exuviae are presented. The final chapter discusses research opportunities on North American Anisoptera nymphs, including taxonomic needs, studies on structure and function, life history and microhabitat, water quality indices and conservation efforts. The habitus drawings of all genera are arranged according to family in five plates (Appendix I); although the book is intended as a lab manual, these plates conveniently allow for comparison based on nymph shape making field identification to genus possible in many cases. Appendix II contains a brief history of dragonfly nymph studies in North America. A glossary and an index to scientific names are included.

Download or read book Freshwater Algae of North America written by John D. Wehr and published by Elsevier. This book was released on 2002-12-15 with total page 935 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater algae are among the most diverse and ubiquitous organisms on earth. They occupy an enormous range of ecological conditions from lakes and rivers to acidic peat swamps, inland saline lakes, snow and ice, damp soils, wetlands, desert soils, wastewater treatment plants, and are symbionts in and on many plants, fungi, and animals. In North America, the variety of freshwater habitats colonized by algae is very rich, and offers an enormous and fascinating range of environments for their study. They form the base of most aquatic food webs and are critical to studies of ecosystem health. Algal ecologists and taxonomists play an important role in the understanding of aquatic ecosystems: their biodiversity, productivity, interactions with other organisms, and water quality. This book provides in one volume a practical and comprehensive guide to the genera of freshwater algae known from North America. The format combines the necessary ecological, taxonomic and methodological information for all scientists working in aquatic environments, whether their specialty is in environmental monitoring and water quality assessment, biological composition, ecology, evolution, or molecular biology.Key Features* The first complete accounting of North America's freshwater algal genera in more than 50 years* Includes a guide to the current literature on species identification in each group of algae* High-quality photographs and drawings of more than 770 genera* A clear, easy-to-use introductory key to the diagnostic chapters* Synthetic chapters on freshwater habitats, use of algae in environmental assessment, and control of nuisance algae* Contributions from 27 experts in all areas of freshwater algae* Extensive literature citations* Companion volume of Ecology and Classification of North American Freshwater Invertebrates 2nd edition, edited by Throp and Covich

Download or read book A Guide to Cyanobacteria written by Mark A. Nienaber and published by University Press of Kentucky. This book was released on 2018-06-29 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blue-green algae (also known as cyanobacteria) and the toxins they can produce pose serious economic, environmental, and public health problems worldwide. Much of the scientific and public interest in these microorganisms arises from their tendency to undergo explosive population growth and form harmful blooms, which have inflicted damage in industries as diverse as health care, public utilities, agriculture, recreation, real estate, and commercial and sport fishing. Until now, water quality professionals and other individuals tasked with finding and eliminating cyanotoxins have lacked an accessible guide to these potentially deadly microorganisms. Written for nonspecialists in a clear and straightforward style, this guide will help students, landowners, and citizen scientists identify different kinds of cyanobacteria and understand their impact on waterways, from neighborhood lakes and farm ponds to major river systems. The central feature of the book is a detailed key that systematically walks the reader through each step of the identification process. This key is linked to an extensive set of photographs and a companion smartphone app to assist readers in confirming their findings. Authors Mark A. Nienaber and Miriam Steinitz-Kannan include an ample glossary to help newcomers to the subject get up to speed as well as an in-depth and current bibliography to aid advanced readers in further research. They also offer instructions on how to correctly collect and analyze cyanobacteria. Altogether, this accessible yet comprehensive resource makes important, complex material available to a wide range of professionals and laypeople engaged in combating harmful cyanotoxins.
