Available in PDF, EPUB and Kindle. Book excerpt: An introduction to Ellef Ringnes Island, Prince Patrick Islandand Northern Ellesmere Island. From the preface This project was initiated in 1998 with the development of a surface diatomcalibration set for selected regions from the Arctic Islands.Under the study surface sediments, mosses,rock and otheravailable habitats were studied from 91 ponds and lakes.It became clear that the diatoms observed were new or undocumented. Detailed taxonomic studies were done at the Canadian Museum of Nature using SEM generated images andthe extensive Library. A must have for research in the Arctic
Book Synopsis Freshwater Algae of North America by : John D. Wehr
Download or read book Freshwater Algae of North America written by John D. Wehr and published by Elsevier. This book was released on 2015-06-05 with total page 1067 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater Algae of North America: Ecology and Classification, Second Edition is an authoritative and practical treatise on the classification, biodiversity, and ecology of all known genera of freshwater algae from North America. The book provides essential taxonomic and ecological information about one of the most diverse and ubiquitous groups of organisms on earth. This single volume brings together experts on all the groups of algae that occur in fresh waters (also soils, snow, and extreme inland environments). In the decade since the first edition, there has been an explosion of new information on the classification, ecology, and biogeography of many groups of algae, with the use of molecular techniques and renewed interest in biological diversity. 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

Book Synopsis Fungal Infections of the Central Nervous System by : Mehmet Turgut
Download or read book Fungal Infections of the Central Nervous System written by Mehmet Turgut and published by Springer. This book was released on 2019-07-05 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides comprehensive information on fungal infections of the central nervous system (CNS). Fungal infections are still a major public health challenge for most of the developing world and even for developed countries due to the rising numbers of immune compromised patients, refugee movements, and international travel. Although fungal infections involving the CNS are not particularly common, when they do occur, the results can be devastating in spite of recent advances and currently available therapies. Further, over the past several years, the incidence of these infections has seen a steep rise among immunodeficient patients. In this context, aggressive surgery remains the mainstay of management, but conservative antifungal drug treatment complemented by aggressive surgical debridement may be necessary. Yet the optimal management approach to fungal infections of the CNS remains controversial, owing to the limited individual experience and the variable clinical course of the conditions. Addressing that problem, this comprehensive book offers the ideal resource for neurosurgeons, neurologists and other specialists working with infectious diseases.
Book Synopsis Polar Lakes and Rivers by : Warwick F. Vincent
Download or read book Polar Lakes and Rivers written by Warwick F. Vincent and published by OUP Oxford. This book was released on 2008-09-11 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to describe the ecology of high latitude lakes, rivers and glacial environments in both the North and South polar regions. From the lake-rich floodplains of the Arctic to the deep, enigmatic waters of Lake Vostok, Antarctica, these regions contain some of the most extraordinary aquatic ecosystems on Earth. They provide a fascinating diversity of habitats for plant, animal and microbial communities, and are proving to be valuable model systems for exploring many ecological themes including landscape-lake interactions, adaptation of life to environmental extremes, and controls on the structure and functioning of aquatic ecosystems. Some of these waters also have direct global implications, including permafrost thaw lakes as sources of greenhouse gases, subglacial aquatic environments as a storehouse of ancient microbes, and Arctic rivers as major inputs of freshwater and organic carbon to the World Ocean. Given that many polar areas are experiencing greater climate warming than at lower latitudes, these ecosystems can also be viewed as sentinels of global change. This timely volume brings together many of the world's leading researchers in polar limnology to describe these diverse aquatic environments and their ecology. It introduces each major ecosystem type, examines the similarities and differences between Arctic and Antarctic systems as well as their responses to environmental change, and describes new frontiers for future research. A glossary of terms is provided for non-specialists, and a set of colour plates introduces the ecosystems and their biota. Polar Lakes and Rivers will be of value to students and specialist researchers alike, as well as to those with a more general interest in aquatic ecology, polar environments or global change who require an authoritative overview of this fast emerging topic.

Book Synopsis Diatom Assemblages from Sphagnum Bogs of the World by : Maxim S. Kulikovskiy
Download or read book Diatom Assemblages from Sphagnum Bogs of the World written by Maxim S. Kulikovskiy and published by . This book was released on 2010 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first in the series of volumes that will be devoted to the Eurasian Sphagnum bog diatoms. Sphagnum bogs are unique ecosystems. The main ecological drivers in these systems are Sphagnum mosses. They originate under organic, acidic conditions with low content of available electrolytes. Diatomological studies of the Sphagnum bogs of Russia and adjacent countries began in the 1950s. However, these papers include the floristic information on only a few dozen smaller bogs. Large-scale floristic, taxonomic and biogeographic investigations have not been conducted so far, although this gap has been reduced by a few recent studies. Diatom assemblages from Sphagnum bog Nur, situated in the northern mountainous region of Mongolia, are subject of the study. Nur is a unique ecosystem in Mongolia because it is the only known large Sphagnum bog throughout this region. There are no earlier studies on the algal flora of this ecosystem. A total of 242 diatom taxa, belonging to 48 genera have been identified from samples taken from different habitats of this bog. Light and scanning electron microscope analyses resulted in the description of one new genus, Boreozonacola, and 18 new species from the genera Pinnularia, Stauroneis, Naviculadicta, Fragilaria, Eunotia, Boreozonacola, Caloneis, Chamaepinnularia, and Neidium. Additionally, 11 new taxonomic combinations are suggested. Species treatments include descriptions, synonymies, size dimensions, and relevant literature. For some species historical information is also provided.

Book Synopsis The Vascular Plants of the Western Canadian Arctic Archipelago by : Alf Erling Porsild
Download or read book The Vascular Plants of the Western Canadian Arctic Archipelago written by Alf Erling Porsild and published by Queen's Printer. This book was released on 1955 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: The bulk of the botanical information, published here for the first time, has resulted from the writer's own collection in the course of brief visits in July and August of 1949 to about a dozen points each in Banks and Victoria islands (Porsild, 1950) and to a visit in 1953 to central Axel Heiberg Island. Valuable additional collections, ranging in size from a few to scores, or in a few instances to one hundred or more specimens, have been contributed by scientists working in other fields, by surveyors, or by chance travellers to islands of the Western Archipelago, whose collections have been deposited in the National Herbarium of Canada.
