Download or read book Chrysophyte Algae written by Craig D. Sandgren and published by Cambridge University Press. This book was released on 1995-01-26 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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 Paleolimnology written by Andrew S. Cohen and published by Oxford University Press. This book was released on 2003-05-29 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text, written by a leading researcher in the field, describes the origin and formation of lakes in order to give context to the question of how lacustrine deposits form. It explains the process of sedimentation in lakes and the chemistry of those deposits and describes how the age of lake deposits are determined. Additionally, this book shows how different groups of fossils are used in interpreting the paleontological record of lakes. In order to illustrate the more synthetic approaches to interpreting the history of lakes, the author also discusses such special topics as lake-level history, lake evolution, and the impact of environmental change on lakes.

Download or read book Phytoplankton and Trophic Gradients written by M. Alvarez-Cobelas and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings deal with the relationship between species composition of freshwater phytoplankton and the trophic gradient. Particular regard is paid to the composite question, what lives where and why? Overview papers report the state of the art and suggest that the trophic spectrum appears to be a probabilistic outcome of several dimensions of variability that impinge upon phytoplankton species selection. Studies on community structure span all latitudes from those of Antarctica to equatorial Brazil, and also include reports on light and nutrient gradients, pH and fish-stock effects on species composition. Seasonal and longterm phytoplankton dynamics in lakes of varying trophic status are also considered. Finally, studies on the taxonomy and autoecology of some groups (e.g. Volvocales, Chrysophytes and Euglenophytes) living at the extremes of the trophic spectrum contribute to our knowledge of this usually neglected phytoplankton. This is the first time that a book covers such a topic, and it will prove an excellent source of information to anyone working on phytoplankton ecology and ecological indicators. Limnologists in general, algologists and the technical staff at water authorities will all benefit by reading this book.

Download or read book Atlas of Chrysophycean Cysts written by K. Duff and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chrysophycean algae are a diverse and often abundant group of primarily freshwater phytoplankton, characterized by the endogenous formation of siliceous cysts or stomatocysts (also called statospores or statocysts). Cyst morphology is highly variable, but believed to be species-specific. Recently, cysts have received considerable attention from phycologists and especially paleoecologists who wish to use these indicators for assessments of environmental change. Nonetheless, attempts at using cysts have often been hampered by taxonomic problems. This Atlas dispels some of the mystery surrounding stomatocysts, facilitating the accurate identification of individual cyst morphotypes, and encouraging other workers to begin using these important indicators. The terminology used to describe cysts is outlined in detail, followed by detailed descriptions of cyst morphotypes, following International Statospore Working Group (ISWG) guidelines, complemented by scanning electron and light micrographs, as well as line illustrations. Any available biogeographical and ecological information is also provided. These descriptions will further accelerate the continued effort to link cyst morphotypes to the algae that produce them. For paleoecologists who wish to include stomatocysts in their studies, researchers working with living chrysophycean algae, and those interested in the morphology and ultrastructure of cyst morphotypes.
Download or read book Biodiversity and Earth History written by Jens Boenigk and published by Springer. This book was released on 2015-03-31 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: This uniquely interdisciplinary textbook explores the exciting and complex relationship between Earth’s geological history and the biodiversity of life. Its innovative design provides a seamless learning experience, clarifying major concepts step by step with detailed textual explanations complemented by detailed figures, diagrams and vibrant pictures. Thanks to its layout, the respective concepts can be studied individually, as part of the broader framework of each chapter, or as they relate to the book as a whole. It provides in-depth coverage of: - Earth’s formation and subsequent geological history, including patterns of climate change and atmospheric evolution; - The early stages of life, from microbial ‘primordial soup’ theories to the fossil record’s most valuable contributions; - Mechanisms of mutual influence between living organisms and the environment: how life changed Earth’s history whilst, at the same time, environmental pressures continue to shape the evolution of species; - Basic ideas in biodiversity studies: species concepts, measurement techniques, and global distribution patterns; - Biological systematics, from their historical origins in Greek philosophy and Biblical stories to Darwinian evolution by natural selection, and to phylogenetics based on cutting-edge molecular techniques. This book’s four major sections offer a fresh cross-disciplinary overview of biodiversity and the Earth’s history. Among many other concepts, they reveal the massive diversity of eukaryotes, explain the geological processes behind fossilisation, and provide an eye-opening account of the relatively short period of human evolution in the context of Earth’s 4.6 billion-year history. Employing a combination of proven didactic tools, the book is simultaneously a reading reference, illustrated guide, and encyclopaedia of organismal biology and geology. It is aimed at school- and university-level students, as well as members of the public fascinated by the intricate interrelationship of living organisms and their environment.

Download or read book Silicon and Siliceous Structures in Biological Systems written by T.L. Simpson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: The publication of this book was undertaken with two purposes in view: to bring together informatian on the deposition by living organ isms of unique skeletal structures composed of amorphous silica, and to review recent data on the involvement of silicon in physiological and biochemical processes. Although widely varying viewpoints are represented, all the contributors are very interested in the events in volved in the formatian of siliceaus structures and their function. Data presented deal with these questions in a variety of plant and animal systems, and at levels ranging from the evolutionary to the biochemical and ultrastructural. Innovations in electron microscopy and, indeed, the advent of electron microscopy itself, have stimulated many ultra structural studies of silica deposition, work which has deepened and widened the interest in those organisms which routinely produce "glassy skeletons. " The question of how silicon participates in biological systems in volves a spectrum of fields that indudes the chemistry of silicon per se, its biogeochemistry, biochemistry, ecology, and so forth. In this book, however, attention is focused up on the biological aspects of silicon and siliceous structures, with emphasis on the evolutian, phylogeny, morphology, and distribution of siliceaus structures, on the cellular as peets of silica deposition, and on the physiological and biochemical roles of silicon. This volume represents the first compilatian of such data. Because such a variety of subjects and fields are covered, the reader will have to glean for himself some of the comparative aspects of the data.

Download or read book Flagellates in Freshwater Ecosystems written by R.I. Jones and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is not so very long ago that botanical concensus abandoned the distinction that was drawn between Algae and Flagellata, the latter having been regarded by zoologists as a group of the Protozoa. Even today some colourless flagellates may find themselves occupying different locations in contrasting taxonomic schemes. However, modern developments in ecology have placed greater emphasis on functional attributes of organisms, and hydro biologists have certainly been in the forefront of such changes. Thus we find that flagellates are again the subject of controversy, not so much over their taxonomic position as over their functional position - their role in aquatic ecosystems. At the 22nd Congress of the International Association of Theoretical and Applied Limnology in Lyon, France in August 1983, we conceived the idea of a meeting to discuss 'Flagellates in Freshwater Ecosystems'. This idea was approved by the committee of SIL and we arranged for the meeting to take place during June 1986 at Lammi Biological Station (University of Helsinki) in Finland. Participants from nine countries enjoyed outstanding hospitality from the staff at the Station during a week of lectures, excursions and discussion ses sions. On behalf of the participants we express our thanks for the generous sponsorship received from the Maj and Tor Nessling Foundation, the Academy of Finland, the Finnish Ministry of Education, Lammi Biological Station and the Finnish Limnological Society.
Download or read book Biogeography of Freshwater Algae written by Jørgen Kristiansen and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on a workshop on biogeography of freshwater algae held during the Fifth International Phycological Congress in China 1994. A group of outstanding specialists covering widely different approaches to the subject have been brought together, and this collection of their contributions forms a unique volume: there is no other book on the subject. It thus fills an evident gap in the phycological literature, and will be of major interest to researchers and teachers within phycology, limnology, and evolutionary biology. However, it may also be useful in courses for advanced students.
