Download or read book Amphora and Halamphora from Coastal and Inland Waters of the United States and Japan written by Joshua G. Stepanek and published by . This book was released on 2018-05-15 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors of this volume study and describe the valve morphology of 108 taxa, representing 75 distinct species, in the genera Amphora and Halamphora from aquatic environments in the United States and Japan. Amphora Ehrenberg ex Kützing and Halamphora (Cleve) Levkov are taxonomically diverse genera of raphid diatoms. In addition to being species rich, their ecology is equally diverse, with representatives of the genera present in coastal and inland waters from the tropics to the arctic. Of the 75 species, nearly one-half of them (33) are described as new, including 4 from the genus Amphora and 29 from the genus Halamphora. Eight species are transferred from Amphora to Halamphora and new combinations proposed. All taxa considered herein have been cultured, and 4 genes (the nuclear encoded 18S and 28S rDNA and the chloroplast encoded rbcL and psbC genes) have been sequenced for each. This combination of morphological and molecular data lays an important foundation for future research of the taxonomy, ecology and systematics of the Amphora and Halamphora floras of coastal and inland waters.

Download or read book The Diatom World written by Joseph Seckbach and published by Springer Science & Business Media. This book was released on 2011-07-23 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diatom biology, genomics and ecology are becoming more relevant to the human species. While there have been recent compilations of some of the applied aspects of diatoms, and the dizzying pace of taxonomic revisions, this new volume bring us up to date on their classification, biology and ecology, as well as covering the topics of genomics and applied uses. In this collection, some of the leaders in diatom research present either new information or summarize recent research efforts on a wide range of topics, including the tree of life of diatoms, their classifications, the wide habitats and ecological spectra the group exploits, as well as the beauty of their form. This volume celebrates the diversity, emerging areas of research and fascinating ecology of the diatoms bringing this group of world-renown and emerging research leaders together. 'The Diatom World' will foster greater appreciation and research contributions on this incredibly diverse and fascinating group of organisms.

Download or read book Plastics in the Aquatic Environment Part I written by Friederike Stock and published by Springer Nature. This book was released on 2021-10-29 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive review of how plastic pollution is affecting fresh and marine waters, and what the current challenges in plastic waste assessment and management in the aquatic environment are. Plastic waste comprises particles with heterogeneous physicochemical properties such as large size-range, different shapes and polymer types with various additives determining their environmental fate and risk. This complexity raises several open research questions which are explored in this book. Examples are the plastic uptake by aquatic organisms, degradation processes as well as sources and sinks in the environment. Readers will discover real case studies of plastic pollution detection and management in different parts of the world, including Asia, America and Europe, which provide an integrated overview of the global scope of this issue. This book and the companion volume Plastics in the Aquatic Environment - Part II: Stakeholders' Role Against Pollution are valuable resources to students, researchers, policymakers and environmental managers interested in plastic pollution and working towards its reduction.

Download or read book Identification of Freshwater Diatoms from Live Material written by E.J. Cox and published by Springer. This book was released on 1996-08-31 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: This volume is based on prec'entations at the conference on Culture of Marine Invertebrate Animals which was held in Green port, New York in October, 1972. The conference was sponsored by the Middle Atlantic Natural Sciences Council, Inc., a non profit educational corporation, together with the Marine Science Centers of Adelphi University, the State University of New York at Stony Brook, Long Island University, Suffolk County Community College, and the Shelter Island Oyster Company. The purpose of the conference was to provide a needed ex change of knowledge among scientists of various specialties whose information would be invaluable to others confronted with similar problems, even with different marine animals. Part I considers supportive techniques -- general isolation and culture methods, problems of disease and feeding. Specific techniques employed in the culture of a wide range of invertebrate organisms is covered in Part II. We want to thank the contributors for their cooperation in preparing the manuscripts based on their conference presentations. Walter L. Smith Matoira H.

Download or read book Diatoms written by F. E. Round and published by Cambridge University Press. This book was released on 2007-12-04 with total page 1208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a wide-ranging introduction to the diatoms together with an illustrated description of over 250 genera. Diatoms are important as perhaps the commonest group of autotrophic plants on earth and are abundant in all waters and on soils and moist surfaces. The introduction describes the diatom cell in detail, the structure of the wall (often extremely beautiful in design), the cell contents and aspects of life cycle and cell division. The generic atlas section is the first account of diatom systematics since 1928 (Karsten in Engler and Prantl: Die Nauturlichen Pflanzenfamilien) and each generic description is accompanied by scanning electron micrographs to show the characteristic structure. Most of the latter have been prepared specially for this work from the authors' own collections. The Diatoms will be the standard reference work on the group for years to come and is an essential reference volume.
