Chrysophyte Algae
Author: Craig D. SandgrenPublisher: Cambridge University Press
ISBN: 9780521462600
Category : Science
Languages : en
Pages : 424
Book Description
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.
Paleopalynology
Author: Alfred TraversePublisher: Springer Science & Business Media
ISBN: 1402056109
Category : Science
Languages : en
Pages : 816
Book Description
This book provides complete coverage of all aspects of the study of all fossil palynomorphs yet studied. It is a profusely illustrated treatment. The book serves both as a student text and general reference work. Palynomorphs yield information about age, geological and biological environment, climate during deposition, and other significant factors about the enclosing rocks. Extant spores and pollen are treated first, preparing the student for more difficult work with fossil sporomorphs and other kinds of palynomorphs. An appendix describes laboratory methods. The glossary, bibliographies and index are useful tools for study of the literature.
Tracking Environmental Change Using Lake Sediments
Author: John P. SmolPublisher: Springer Science & Business Media
ISBN: 1402006810
Category : Science
Languages : en
Pages : 383
Book Description
This third volume in the Developments in Paleoenvironmental Research series deals with the major terrestrial, algal, and siliceous indicators used in paleolimnology. Other volumes deal with the acquisition and archiving of lake sediment cores, chronological techniques, and large-scale basin analysis methods (Volume 1), physical and geochemical parameters and methods (Volume 2), zoological techniques (Volume 4), and statistical and data handling methods (Volume 5). These monographs will provide sufficient detail and breadth to be useful handbooks for both seasoned practitioners as well as newcomers to the area of paleolimnology. Although the chapters in these volumes target mainly lacustrine settings, many of the techniques described can also be readily applied to fluvial, glacial, marine, estuarine, and peatland environments.
Paleolimnology
Author: Andrew S. CohenPublisher: Oxford University Press
ISBN: 9780195350890
Category : Science
Languages : en
Pages : 540
Book Description
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.
Changing Prairie Landscapes
Author: Patrick DouaudPublisher: University of Regina Press
ISBN: 9780889771468
Category : Nature
Languages : en
Pages : 218
Book Description
Landscapes of the Northern Great Plains have been constantly changing, but never so rapidly as under modern conditions of economic affluence and technological development. This change is multifaceted and has an impact not only on the fabric of culture and its perception of landscape, but also on the ecology and physical landforms. Multidisciplinary research has therefore become an important tool in identifying the influences that human activities have, not only on cultural landscapes but on biophysical ones as well. This collection of articles, originating in a conference held at the Royal Saskatchewan Museum in April 2000, focuses on just such an integration of research concerning the Great Plains of North America and involving the disciplines of geology, archaeology, biology, geography, sociology, and agriculture.
Atlas of Chrysophycean Cysts
Author: K. DuffPublisher: Springer Science & Business Media
ISBN: 9401708096
Category : Science
Languages : en
Pages : 196
Book Description
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.
