Available in PDF, EPUB and Kindle. Book excerpt: Once thought of as a pristine environment, it is now all too apparent that the Arctic is a sink for pollutants transported northwards over long distances in the atmosphere and oceans, and is also likely to be subject to major climate change as a result of global warming. Many ecologists are currently seeking to further our understanding of how arctic ecosystems function, and to detect and predict anthropogenic changes which may occur within them. This book, resulting from a British Ecological Society Special Symposium, addresses these issues.

This book was released on 2017-09-13 with total page 1117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook in two volumes synthesises our knowledge about the ecology of Central Europe’s plant cover with its 7000-yr history of human impact, covering Germany, Poland, the Netherlands, Belgium, Luxembourg, Switzerland, Austria, Czech Republic and Slovakia. Based on a thorough literature review with 5500 cited references and nearly 1000 figures and tables, the two books review in 26 chapters all major natural and man-made vegetation types with their climatic and edaphic influences, the structure and dynamics of their communities, the ecophysiology of important plant species, and key aspects of ecosystem functioning. Volume I deals with forests and scrub vegetation and analyses the ecology of Central Europe’s tree flora, whilst Volume II is dedicated to the non-forest vegetation covering mires, grasslands, heaths, alpine habitats and urban vegetation. The consequences of over-use, pollution and recent climate change over the last century are explored and conservation issues addressed.

Download or read book Clean Technology and the Environment written by R. Kirkwood and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many environmental problems resulting from atmospheric, land and water pollution are now widely understood. The combination of both improved technology and legislative pressure has led to a reduction in pollution from industrial practices in the West in recent years. However, sustainable development is dependent upon a new approach to environmental protection - clean technology. This book is in two parts. The first explores the ecological principles governing the function of ecosystems, sustain ability and biodiversity (Chapter 1) and the problems resulting from atmospheric pollution (Chapter 2), water pollution (Chapter 3) and land pollution (Chapter 4). For example, there is increasing international concern that the combustion of fossil fuels is leading to an increase in the levels of carbon, sulphur and nitrogen gases which pollute the atmosphere of our planet. The enhanced levels of carbon gases such as carbon dioxide may cause change in our global climate and, in tum, lead to flooding and loss of low-lying coastal regions. In addition, the deposition of sulphur and nitrogen oxides is believed to be the cause of 'acid rain' which has led to loss of fish stocks from upland lochs and damage to forestry plantations.

Download or read book The Sphagnum Species of the World written by Dierck Michaelis and published by . This book was released on 2019-11-21 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sphagnum specialist Dierk Michaelis documents the worldwide known peat moss species (genus Sphagnum) and presents keys for their identification. It represents the updated, supplemented English language version of the author's original peat moss flora of 2011 (in German), the first overall presentation of Sphagnum since Carl Warnstorf's "Sphagnologia Universalis" of 1911. Compared to the German edition, 12 species have been added, 23 new plates were added, the chapters on phylogeny and research history have been revised and a new chapter on Sphagnum ecology has been added. Since Warnstorf's comprehensive work, numerous names have been recognized and revised as synonyms - particularly by Andrews, Eddy and Isoviita. These revisions, and the approximately 150 new species described since then, have been incorporated into this volume, as well as the results of the author's own studies. Genetic characteristics were used to define the species of problematic groups. The peat mosses are of key ecological and economic importance among the mosses. They populate almost all continents with a clear focus on northern South America, North America, East and North Asia and Europe. The genus Sphagnum is very isolated within the Bryopsida, similarities in the construction of the sporophyte indicate a distant relation to the rockmosses (class Andreaeopsida). For the internal classification of Sphagnum there are very different approaches with up to 4 subgenera and up to 18 possible sections, of which 14 are distinguished in this volume. Peat mosses in the narrow sense (genus Sphagnum) feature a combination of leaf dimorphism (stem and branch leaves), cell dimorphism (living chlorophyll and empty hyaline cells) and branch dimorphism (strongly assimilating spreading branches and hanging branches serving the outer water supply) that is unique among mosses. Although the assignment of any peat moss to the genus Sphagnum usually does not cause any problems, the determination down to the species level causes difficulties sometimes. The author introduces and describes the anatomy and morphology of Sphagnum, and explains the reproductive biology, the research history and phylogenesis of peat mosses. The systematic part is divided into three segments: Description and identification of the sections, keys for all peat moss species, separated by continents, as well as Sphagnum species lists for 20 phytogeographic regions of the world. The keys for Africa, Europe and North America are based on existing data and were revised and supplemented with the help of recent descriptions, updated species concepts and new floristic data. Completely new keys have been developed for South America and Asia, as these did not exist pr1eviously. 292 peat moss species are described in detail, supplemented by data on habitats, geographical distribution and lists of synonyms. This section is supplemented by the presentation of the inner and outer characteristics on 219 plates. A very extensive bibliography rounds off the volume.
