Download or read book Ecology of Fresh Waters written by Brian Moss and published by John Wiley & Sons. This book was released on 2010-05-10 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new edition of an established textbook provides a comprehensive and stimulating introduction to rivers, lakes and wetlands, and was written as the basis for a complete course on freshwater ecology. Designed for undergraduate and early postgraduate students who wish to gain an overall view of this vast subject area, this accessible guide to freshwater ecosystems and man's activities will also be invaluable to anyone interested in the integrated management of freshwaters. The author maintains the tradition of clarity and conciseness set by previous editions, and the text is extensively illustrated with photographs and diagrams. Examples are drawn from the author's experience in many parts of the world, and the author continues to stress the human influence. The scientific content of the text has been fully revised and updated, making use of the wealth of data available since publication of the last edition. Professor Brian Moss is a lecturer in Applied Ecology at the University of Liverpool, and has written three previous editions of this well-established textbook.

Download or read book Animal Life in Fresh Water written by Helen Mellanby and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: by Professor L. E. Eastham Formerly Professor of Zoology in the University of Sheffield Most books are written with the intention of supplying some particular need, but few end with such single purpose. Mrs. Mellanby's is no exception, for while the author planned this work to serve as a guide to the school pupil, which function it fulfils in an admirable way, it will also prove of value to the teacher, the university student and the amateur naturalist. While it may be argued that it is not the function of the Uni versities to teach Natural History in the commonly accepted sense, it will always be the aim of Zoologists to know more about animals, what they are and do, where they live and why they live in particular environments. It is unfortunate, in view of the fact that the majority of students of Zoology enter the teaching pro fession, that the increasing load of instruction in morphology, physiology, cytology, genetics, evolution and the like frequently makes a personal study of animal life in relation to environment almost impossible. The fortunate ones visit the sea for a fort night's course in Marine Ecology; the others take posts in schools without even this respite and set about converting their academic learning to a school curriculum. The result is an undesirable and often slavish imitation of university method in the school class room.

This book was released on 2013-04-17 with total page 651 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nils-Axel Marner &Wibjarn Karlen Organizers of the Stockholm Symposium in 1983 Stockholm University, Sweden This book is the Proceedings of the SECOND NORDIC SYMPOSIUM ON CLIMATIC CHANGES AND RELATED PROBLEMS held in Stockholm, Sweden, May 16-20, 1983 (Frydendahl et al., 1983; Marner, 1983). This was "an international interdisciplinary symposium with special refe rence to Nordic records and their relation to global climatic changes". The first NORDIC SYMPOSIUM ON CLIMATIC CHANGES AND RELATED PROBLEMS was held in Copenhagen in 1978 ( Frydendahl, 1978) and had a very broad scientific program. The SECOND NORDIC SYMPOSIUM was specifically directed to certain problems, time ranges and sources of information, as discussed below. Scandinavia is a classical area for the study of climatic fluctuations during the last 20,000 years . A major part of the basic data for the international theories and synthesis originate from Scandinavian data. This applies, for example, to: (1) The drastic climatic fluctuations in connection with the re cession of the land-ice giving rise to the alternation of inter stadials (warm periods with rapid ice recession) and stadials (cold periods with readvances or retardations in the ice recession). (2) The climatic changes during the Holocene with its well-known sub-division according to the Blytt-Sernander system (nowadays being used far outside the boreal region for which it was origi nally defined). (3) The Holocene climatic optimum and the subsequent climatic de terioration at around 2500 BP (well-established already at the beginning of this century).

This book was released on 2011-04-23 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite our growing awareness of the vital role they play in the global environment, wetlands remain among the most endangered ecosystems on Earth and are still being destroyed and degraded at an alarming rate. This much-needed publication, which includes contributions from leading researchers and practitioners, presents a holistic perspective on the restoration of wetland ecosystems such as shallow lakes, streams, floodplains and bogs. Through the use of carefully chosen case studies, the authors examine European wetland restoration projects from Scandinavia to Bulgaria and from Ireland to Belarus, focusing on the lessons they can teach to a new generation of conservationists. As well as reviewing the sum of current knowledge on the subject, the text is a store of practical know-how, covering a wide range of conservation approaches and techniques. It analyzes the major problems in the field and identifies key principles for achieving sustainability in wetland restoration. The topics covered include: • the role of wetlands in landscape functioning • human interference with natural processes such as water and matter cycles and energy dissipation • the impact of land use on global problems such as climate change, floods and droughts • the role played by diversity in wetland functioning The work shows that without sustainable land use over the totality of their catchment areas, and without cohesive inter-agency cooperation, individual restoration projects will have a short life span. The balance between scientific background and practical restoration makes this book a valuable resource for scientists as well as wetland managers, decision makers and land use planners, as well as students of ecology, nature conservation and environmental protection.
