Book Synopsis Cell Cycle Dynamics and the Physiology of Saxitoxin Biosynthesis in Alexandrium Fundyense (Dinophyceae) by : Gaspar Taroncher Oldenburg
Download or read book Cell Cycle Dynamics and the Physiology of Saxitoxin Biosynthesis in Alexandrium Fundyense (Dinophyceae) written by Gaspar Taroncher Oldenburg and published by . This book was released on 1998 with total page 738 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine dinoflagellates in the genus Alexandrium synthesize Saxitoxin (STX) and several of its derivatives. The aim of this thesis was to analyze novel aspects of toxigenesis and the cell cycle in Alexandrium and to apply molecular techniques to gain new insights on the regulation of STX biosynthesis. Synchronized cultures of A. fundyense were studied to determine the dynamics of toxin production throughout the cell cycle. STX biosynthesis was shown to be discontinuous and constrained to approximately 10 hours at the beginning of G1. Two cell cycle transition points were identified: a light-dependent one and a size-dependent one. Semi-continuous cultures of A. fundyense were used to determine the effects of temperature and phosphate limitation on the coupling of STX biosynthesis to O%. Inferred toxin production rates were constant and correlated to G1 over a range of growth rates. The effects of phosphate on STX biosynthesis were analyzed and a scheme of interconversions among STX derivatives is proposed. Differential Display (DD) analysis was applied to the identification of up- or downregulated genes during toxigenesis in A. fundyense. The expression patterns of S-adenosylhomocysteine hydrolase, methionine aminopeptidase and a histone-like protein were related to periods of STX biosynthesis.

Book Synopsis Chemical Biomarkers in Aquatic Ecosystems by : Thomas S. Bianchi
Download or read book Chemical Biomarkers in Aquatic Ecosystems written by Thomas S. Bianchi and published by Princeton University Press. This book was released on 2011-02-28 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides a unique and thorough look at the application of chemical biomarkers to aquatic ecosystems. Defining a chemical biomarker as a compound that can be linked to particular sources of organic matter identified in the sediment record, the book indicates that the application of these biomarkers for an understanding of aquatic ecosystems consists of a biogeochemical approach that has been quite successful but underused. This book offers a wide-ranging guide to the broad diversity of these chemical biomarkers, is the first to be structured around the compounds themselves, and examines them in a connected and comprehensive way. This timely book is appropriate for advanced undergraduate and graduate students seeking training in this area; researchers in biochemistry, organic geochemistry, and biogeochemistry; researchers working on aspects of organic cycling in aquatic ecosystems; and paleoceanographers, petroleum geologists, and ecologists. Provides a guide to the broad diversity of chemical biomarkers in aquatic environments The first textbook to be structured around the compounds themselves Describes the structure, biochemical synthesis, analysis, and reactivity of each class of biomarkers Offers a selection of relevant applications to aquatic systems, including lakes, rivers, estuaries, oceans, and paleoenvironments Demonstrates the utility of using organic molecules as tracers of processes occurring in aquatic ecosystems, both modern and ancient
Book Synopsis Ecology and the Environment by : Russell K. Monson
Download or read book Ecology and the Environment written by Russell K. Monson and published by Springer. This book was released on 2014-10-02 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, plant biology is considered from the perspective of plants and their surrounding environment, including both biotic and abiotic interactions. The intended audience is undergraduate students in the middle or final phases of their programs of study. Topics are developed to provide a rudimentary understanding of how plant-environment interactions span multiple spatiotemporal scales, and how this rudimentary knowledge can be applied to understand the causes of ecosystem vulnerabilities in the face of global climate change and expansion of natural resource use by human societies. In all chapters connections are made from smaller to larger scales of ecological organization, providing a foundation for understanding plant ecology. Where relevant, environmental threats to ecological systems are identified and future research needs are discussed. As future generations take on the responsibility for managing ecosystem goods and services, one of the most effective resources that can be passed on is accumulated knowledge of how organisms, populations, species, communities and ecosystems function and interact across scales of organization. This book is intended to provide some of that knowledge, and hopefully provide those generations with the ability to avoid some of the catastrophic environmental mistakes that prior generations have made.

This book was released on 2011-06-21 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book places the main actors in environmental microbiology, namely the microorganisms, on center stage. Using the modern approach of 16S ribosomal RNA, the book looks at the taxonomy of marine and freshwater bacteria, fungi, protozoa, algae, viruses, and the smaller aquatic animals such as nematodes and rotifers, as well as at the study of unculturable aquatic microorganisms (metagenomics). The peculiarities of water as an environment for microbial growth, and the influence of aquatic microorganisms on global climate and global recycling of nitrogen and sulphur are also examined. The pollution of water is explored in the context of self-purification of natural waters. Modern municipal water purification and disease transmission through water are discussed. Alternative methods for solid waste disposal are related to the economic capability of a society. Viruses are given special attention. By focusing on the basics, this primer will appeal across a wide range of disciplines.
