This book was released on 2012-12-06 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is enough to work on the assumption that all of the details matter in the end, in some unknown but vital way. Edward O. Wilson, Biophilia Advances in knowledge of northern ecology have been so rapid that to undertake a synthesis of all the literature now available would be a major enterprise, perhaps even a life's work, and so it must be considered permissible to fill in a few gaps, follow one's own inclinations, leaving comprehensive syntheses to those willing to undertake them. This is the rubric under which I have written, reporting some of the more interesting data I and others have obtained over the years, often diverging into discussions of plants, soils, climate, and faunal relationships which have perhaps not previously been dealt with extensively, or at least in quite the same way. This is purely intentional, since I find it difficult to summon up the needed enthusiasm, at this late hour, to write on topics which unfortunately for me have little attraction. I have thus written for the pleasure derived from depicting, perhaps at times as something of an impressionist, a fascinating biotic region, a captivating land, a collection of interesting ecological problems, environmental relationships to be discerned in part, perhaps understood to some small degree, perhaps one day to be modeled mathematically. As Leo Szilard once wrote: ': . . to be able to say even this much might be of some value" (Szilard, 1960).

Download or read book The Ecology of River Systems written by Bryan R. Davies and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 788 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of the ecology of running waters has come a long way during the past few years. From being a largely descriptive subject, with a few under tones concerned with such things as fisheries, pollution or control of blackflies, it has evolved into a discipline with hypotheses, such as the River Continuum Concept (Vannote et a/. 1980), and even a book suggesting that it offers opportunity for the testing of ecological theory (Barnes & Minshall 1983). However, perusal of the literature reveals that, although some of the very early studies were concerned with large rivers (references in Hynes 1970), the great mass of the work that has been done on running water has been on streams and small rivers, and information on larger rivers is either on such limited topics as fisheries or plankton, scattered among the journals, or not available to the general limnologist. The only exceptions are a few books in this series of publications, such as those on the Nile (Rz6ska 1976), the Volga (Morduckai Boltovskoi 1979) and the Amazon {Sioli 1984), and the recent compendium by Whitton (1984) on European rivers, among which there are a few that rate as large.
Download or read book Arctic Ordeal written by Sir John Richardson and published by McGill-Queen's Press - MQUP. This book was released on 1994 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Only a handful of the original members of Sir John Franklin's first Arctic expedition returned. John Richardson was one of them. His journal recounts their journey across the Barren Grounds, providing many details not found in Franklin's own 1823 narrative and raising questions about Franklin's ability as a leader. In addition to his achievements as a doctor, meteorologist, and cartographer, Richardson was the first great naturalist to study the North American Arctic. His journal made such an outstanding contribution to ornithology, ichthyology, botany, and geology that much of modern Arctic research is founded upon his observations.

Download or read book Applications of SEM Automated Mineralogy written by Bernhard Schulz and published by MDPI. This book was released on 2021-04-09 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, software developments in Scanning Electron Microscopy (SEM) provoked a notable increase of applications to the study of solid matter. The mineral liberation analysis (MLA) of processed metal ores was an important drive for innovations that led to QEMSCAN, MLA and other software platforms. These combine the assessment of the backscattered electron (BSE) image to the directed steering of the electron beam for energy dispersive spectroscopy (EDS) to automated mineralogy. However, despite a wide distribution of SEM instruments in material research and industry, the potential of SEM automated mineralogy is still under-utilised. The characterisation of primary ores, and the optimisation of comminution, flotation, mineral concentration and metallurgical processes in the mining industry by generating quantified data, is still the major application field of SEM automated mineralogy. However, there is interesting potential beyond these classical fields of geometallurgy and metal ore fingerprinting. Slags, pottery and artefacts can be studied in an archeological context for the recognition of provenance and trade pathways; soil, and solid particles of all kinds, are objects in forensic science. SEM automated mineralogy allows new insight in the fields of process chemistry and recycling technology.
Download or read book The Periglacial Environment written by Hugh M. French and published by John Wiley & Sons. This book was released on 2017-10-27 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Periglacial Environment, Fourth Edition, is an authoritative overview of the world’s cold, non-glacial environments. First published in 1976 and subsequently revised in 1996 and 2007, the text has been the international standard for nearly 40 years. The Fourth Edition continues to be a personal interpretation of the frost-induced conditions, geomorphic processes and landforms that characterize periglacial environments. Part One discusses the periglacial concept and describes the typical climates and ecosystems that are involved. Part Two describes the geocryology (permafrost science) associated with frozen ground. Part Three outlines the weathering and geomorphic processes associated with cold-climate conditions. Part Four provides insight into the periglacial environments of the Quaternary, especially the Late Pleistocene. Part Five describes some of the problems associated with human occupancy in regions that experience frozen ground and cold-climate conditions. Extensively revised and updated Written by an expert with over 50 years of field research Draws upon the author’s personal experience from Northern Canada, Alaska, Siberia, Tibet, Antarctica, Svalbard, Scandinavia, southern South America, Western Europe and eastern North America This book is an invaluable reference for advanced undergraduates in geography, geology, earth sciences and environmental sciences programs, and to resource managers and geotechnical engineers interested in cold regions.

Download or read book Periglacial Processes and Landforms in Britain and Ireland written by John Boardman and published by Cambridge University Press. This book was released on 2011-04-14 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 1987 book examines the intimate link between periglacial geomorphology and the fluctuating climates of the Quaternary Period in the British Isles. In the last two million years, ice sheets have covered northern Britain several times. In the south, at the limit of the glaciation, intense frost action and the formation of permafrost have influenced past and present landscapes. The first part of the book looks at areas of the world that have climates similar to periglacial Britain: Scandinavia, the Canadian Arctic, and alpine regions. Contributors then present data on periglacial landforms in the British Isles. Topics discussed include the periglaciation of upland Britain, ground ice depressions, and pingo remnants. The regions surveyed stretch from northern Scotland to the Isles of Scilly. The contributions are based on a conference held in late 1985 under the sponsorship of the International Geographical Union and the Quaternary Research Association of the United Kingdom.
