Download or read book The Diatoms written by John P. Smol and published by Cambridge University Press. This book was released on 2010-09-30 with total page 687 pages. Available in PDF, EPUB and Kindle. Book excerpt: This much revised and expanded edition provides a valuable and detailed summary of the many uses of diatoms in a wide range of applications in the environmental and earth sciences. Particular emphasis is placed on the use of diatoms in analysing ecological problems related to climate change, acidification, eutrophication, and other pollution issues. The chapters are divided into sections for easy reference, with separate sections covering indicators in different aquatic environments. A final section explores diatom use in other fields of study such as forensics, oil and gas exploration, nanotechnology, and archaeology. Sixteen new chapters have been added since the first edition, including introductory chapters on diatom biology and the numerical approaches used by diatomists. The extensive glossary has also been expanded and now includes over 1,000 detailed entries, which will help non-specialists to use the book effectively.

Download or read book Diatom Gliding Motility written by Stanley A. Cohn and published by John Wiley & Sons. This book was released on 2021-09-08 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: DIATOM GLIDING MOTILITY Moving photosynthetic organisms are still a great mystery for biologists and this book summarizes what is known and reports the current understanding and modeling of those complex processes. The book covers a broad range of work describing our current state of understanding on the topic, including: historic knowledge and misconceptions of motility; evolution of diatom motility; diatom ecology & physiology; cell biology and biochemistry of diatom motility, anatomy of motile diatoms; observations of diatom motile behavior; diatom competitive ability, unique forms of diatom motility as found in the genus Eunotia; and models of motility. This is the first book attempting to gather such information surrounding diatom motility into one volume focusing on this single topic. Readers will be able to gather both the current state of understanding on the potential mechanisms and ecological regulators of motility, as well as possible models and approaches used to help determine how diatoms accomplish such varied behaviors as diurnal movements, accumulation into areas of light, niche partitioning to increase species success. Given the fact that diatoms remain one of the most ecologically crucial cells in aquatic ecosystems, we hope that this volume will act as a springboard towards future research into diatom motility and even better resolution of some of the issues in motility. Audience Diatomists, phycologists, aquatic ecologists, cellular physiologists, environmental biologists, biophysicists, diatom nanotechnologists, algal ecologists, taxonomists.

Download or read book Cave Biology written by Aldemaro Romero and published by Cambridge University Press. This book was released on 2009-07-23 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biospeleology, the study of organisms that live in caves, has a tremendous potential to inform many aspects of modern biology; yet this area of knowledge remains largely anchored in neo-Lamarckian views of the natural world in both its approaches and jargon. Written for graduate students and academic researchers, this book provides a critical examination of current knowledge and ideas on cave biology, with emphasis on evolution, ecology, and conservation. Aldemaro Romero provides a historical analysis of ideas that have influenced biospeleology, discusses evolutionary phenomena in caves, from cave colonization to phenotypic and genotypic changes, and integrates concepts and knowledge from diverse biological viewpoints. He challenges the conventional wisdom regarding the biology of caves, and highlights urgent questions that should be addressed in order to get a better and more complete understanding of caves as ecosystems.

Download or read book Ecology of Cyanobacteria II written by Brian A. Whitton and published by Springer Science & Business Media. This book was released on 2012-07-05 with total page 753 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyanobacteria have existed for 3.5 billion years, yet they are still the most important photosynthetic organisms on the planet for cycling carbon and nitrogen. The ecosystems where they have key roles range from the warmer oceans to many Antarctic sites. They also include dense nuisance growths in nutrient-rich lakes and nitrogen-fixers which aid the fertility of rice-fields and many soils, especially the biological soil crusts of arid regions. Molecular biology has in recent years provided major advances in our understanding of cyanobacterial ecology. Perhaps for more than any other group of organisms, it is possible to see how the ecology, physiology, biochemistry, ultrastructure and molecular biology interact. This all helps to deal with practical problems such as the control of nuisance blooms and the use of cyanobacterial inocula to manage semi-desert soils. Large-scale culture of several organisms, especially "Spirulina" (Arthrospira), for health food and specialist products is increasingly being expanded for a much wider range of uses. In view of their probable contribution to past oil deposits, much attention is currently focused on their potential as a source of biofuel. Please visit http://extras.springer.com/ to view Extra Materials belonging to this volume. This book complements the highly successful Ecology of Cyanobacteria and integrates the discoveries of the past twelve years with the older literature.

Download or read book The Roadside Geology of Namibia written by Gabi Schneider and published by . This book was released on 2008 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Namibia has over the years attracted scientists from all over the world to study its geology, uniquely exposed in the desert environment. Their research has shaped geological thinking worldwide, and led to the development of many new concepts. Due to an arid climate and low population density, geological features are ever present and eye-catching in Namibia. It is for these reasons, that both scientists and laymen are attracted to the country, and many a tourist develops a keen interest in geology when touring this beautiful country. In this second, revised edition, text, figures and cover have been corrected and optimized.

Download or read book Prokaryotes and Evolution written by Jean-Claude Bertrand and published by Springer. This book was released on 2019-01-01 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to show the essential and indispensable role of prokaryotes in the evolution of aliving world. The evolutionary success of prokaryotes is explained together with their role in the evolution of the geosphere, the biosphere and its functioning, as well as their ability to colonize all biotopes, including the most extreme ones. We consider that all past and present living beings emerged from prokaryotes and have interacted with them. Forces and mechanisms presented in the various theories of evolution apply to prokaryotes. The major stages of their evolution and biodiversity are also described. Finally, it is emphasized that prokaryotes are living organisms that provide indisputable evidence of evolutionary processes. Many examples of ongoing evolution in prokaryotes, observable at the human scale, are provided.
