Available in PDF, EPUB and Kindle. Book excerpt: Diatoms are an important element of many polar marine microbial communities and particularly abundant in Antarctic lakes. However, few comprehensive studies, such as the study presented in this volume are available on Antarctic communities. The diatom floras encountered in surface sediment samples from 33 lakes of the Vestfold Hills, Antarctica are presented. 67 distinct diatom species were identified in these sediments. They include cosmopolitan, Southern Ocean, endemic Antarctic and new diatoms. Each species encountered is described and illustrated; autecological information on the species is included where possible. Epilimnion water chemistry of the lakes sampled was determined to investigate their influence on diatom distribution. The studied lakes span a very large range of salinities from 0.5 to 165 permil. The authors show that salinity seems to have a strong influence on the observed diatom taxa.

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 Antarctic Lakes written by Johanna Laybourn-Parry and published by OUP Oxford. This book was released on 2014-08-14 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Antarctic continent carries the greatest diversity of lake environments on the planet: freshwater and saline lakes, tidal freshwater epishelf lakes, lakes on ice shelves and glacier surfaces, and over three hundred subglacial lakes; extraordinary ecosystems that have been separated from the atmosphere for up to millions of years. This book provides a unique and cutting edge synthesis of Antarctic limnology, drawing together current knowledge on geomorphology, morphometry, chemistry, community structure and function. It emphasises throughout the value of these near-pristine ecosystems as barometers of climate change, showing how responsive and vulnerable they are to the indirect impacts of anthropogenic activity. Antarctic Lakes begins with an introduction to their physical, chemical, and biological characteristics, providing a basis for understanding the subsequent detailed chapters on different lake types, and ends with a chapter considering the application of new technologies to polar limnology as well as identifying future research directions. This accessible text is suitable for both senior undergraduate and graduate students taking courses in Antarctic and polar limnology, and will also be of broad interest to researchers working in the areas of polar science, microbial ecology (and extremophiles), climatology, glaciology, and astrobiology.

This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume was conceived as a companion to 'Antarctic Oasis: Terrestrial environments and history of the Vestfold Hills' edited by J. Pickard and published in 1986 by Academic Press, Sydney. Pickard's book contains accounts of the Vestfold Hills' climate (N. A. Streten) and recent geomorphological history (D. A. Adamson & J. Pickard) which provide a valuable context for understanding their present day biology. Pickard also gives a history of human discovery and occupation of the Vest fold Hills. There is some overlap in the coverage, to the extent that both this volume and Pickard's book describe the terrestrial flora and fauna. The reader specifically interested in the terrestrial ecosystems of the Vestfold Hills should draw from both sources. Together, these works present a broad and descriptive account of the largest truly coastal antarctic oasis: a region that holds a unique variety of opportunities for future scientific investigation. There are several tasks I wish to accomplish here, apart from expressing my sincere thanks to the many people who have contributed to the completion of this volume. I wish to briefly introduce the Vestfolds and to list some of the features that, in my opinion, make them biologically varied, and unique in the context of other coastal ice-free areas. I wish to describe the phases of biological research in this region, including the directions that have been pursued since the 1984 symposium and to comment upon the future of the Vestfold Hills.

Book excerpt: The Antarctic provides a suite of scenarios useful for investigating the range of climate change effects on terrestrial and limnetic biota. The purpose of the book is to provide, based on the most up to date knowledge, a synthesis of the likely effects of climate change on Antarctic terrestrial and limnetic ecosystems and, thereby, to contribute to their management and conservation, based on the information.
Download or read book Freshwater Diatoms from Ile de la Possession Crozet Archipelago Subantarctica written by Bart Van de Vijver and published by . This book was released on 2002 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: The freshwater and terrestrial diatom composition of the Subantarctic island Ile de la Possession is investigated in detail. The island is part of the Crozet Archipelago, situated in the southern Indian Ocean. A total of 220 diatom taxa, belonging to 44 genera have been identified after surveying more than 500 samples, taken from all over the island. The most diverse genera are Pirmularia (41 taxa), Nitzschia (19 taxa), Psammothidium (13 taxa) and Diadesmis (11 taxa). Detailed SEM analysis of all observed taxa resulted in the description of several new species and varieties, especially in the genera Diadesmis and Pinnularia, whereas several others need further observations to be described later on as new taxa. In addition, the taxonomy of the so-called Subantarctic taxa has been thoroughly revised based on the most recent insights. All taxa are morphologically and ecologically characterized and elaborately documented with both LM and SEM micrographs.

Available in PDF, EPUB and Kindle. Book excerpt: This publication is composed of papers presented at an International Symposium on Athalassic (Inland) Salt Lakes, which was hosted by the University of Adelaide, South Australia, during a week in October 1979. The genesis of the Symposium was at the Copenhagen Congress of the International Association of Limnology (S.1. L.) where it was noted that a number of papers concerned with inland saline lakes were distributed throughout sessions in such a way as to make it difficult to attend all of them. A number of participants at the Congress felt that the ecology of salt lakes had greater homogeneity or cohesiveness than this sort of distribution would suggest, and it was decided that a symposium on salt lakes be held. The symposium was the first under the aegis of the S.l. L. to be held in Australia, and it was very well attended, with participants coming from many countries. The week long programme produced a number of lively and interesting sessions on all aspects of athalassic saline lakes. Participants stayed on after the Symposium for an expedition to Lake Eyre, in the nQrth of South Australia, and were given one of the best of all possible introductions to the Australian environment.
Download or read book Microbial Ecosystems of Antarctica written by Warwick F. Vincent and published by Cambridge University Press. This book was released on 2004-03-11 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: A structured account of the full range of environments in Antarctica and of the microbial communities that live within them. The author examines the major features of the chemical and physical environment in each habitat, and the influence of these features on the population structure and dynamics of their microbiota. Each chapter considers a specific type of environment, the microbial species that dominate, their community structure and dynamics, and the microbial processes that operate and have been measured in the ecosystem. The chapters conclude with an overview of the ecosystem trophic structure and an introduction to the larger organisms that depend on the microbiota. Separate chapters examine the range of cellular strategies adopted by microorganisms within the Antarctic environment, and the increasing influence of humans on these communities.
Download or read book Antarctic Ecosystems written by Alex D. Rogers and published by John Wiley & Sons. This book was released on 2012-02-28 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its discovery Antarctica has held a deep fascination for biologists. Extreme environmental conditions, seasonality and isolation have lead to some of the most striking examples of natural selection and adaptation on Earth. Paradoxically, some of these adaptations may pose constraints on the ability of the Antarctic biota to respond to climate change. Parts of Antarctica are showing some of the largest changes in temperature and other environmental conditions in the world. In this volume, published in association with the Royal Society, leading polar scientists present a synthesis of the latest research on the biological systems in Antarctica, covering organisms from microbes to vertebrate higher predators. This book comes at a time when new technologies and approaches allow the implications of climate change and other direct human impacts on Antarctica to be viewed at a range of scales; across entire regions, whole ecosystems and down to the level of species and variation within their genomes. Chapters address both Antarctic terrestrial and marine ecosystems, and the scientific and management challenges of the future are explored.
