Download or read book Conservation of Endangered Freshwater Fish in Europe written by Arthur Kirchhofer and published by Birkhäuser. This book was released on 2012-12-06 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two events have recently improved the prospects of protecting fish and their environment in Switzerland: the acceptance of a new Federal Water Protection Law in the plebiscite of May 17th 1992, and the new Federal Legislation on Fisheries, in force since January 1st 1994. With this legal framework, the possibilities for protection of nature and landscape have now considerably improved in Switzerland. The most important aims of the Federal Law on Water Protection are to safeguard the natural habitats of the native flora and fauna and water as the habitat of aquatic organisms. This includes not only the preservation or restoration of water quality in lakes and rivers, but also, in rivers used for hydroelectricity, irrigation or as industrial or other water supplies, the maintenance of sufficient water to fulfill the minimal requirements for fish. However, good quality water in sufficient quan tities alone is not enough to guarantee the survival of fish. Intact fish habitats comprise various phYsical structures including plenty of hiding places, hunting grounds, reproduction and nursery areas within suitable distances from each other. This third aspect of conservation and restoration of aquatic habitats is a central point in the new Federal Law on Fisheries. Whereas the former versions of this law were more concerned with fishery regulations, the recent legislation defines new areas of responsibility for the federal and the cantonal governments.
Download or read book Human Impact on Danube Watershed Biodiversity in the XXI Century written by Doru Bănăduc and published by Springer Nature. This book was released on 2020-04-20 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second-longest European river after the Volga, the Danube is one of the world’s most important rivers in terms of its geographical and historical significance. In recent history, it has served as a major international waterway and numerous cities, including four capitals, have been founded on its banks. The 2826km-long Danube has a watershed measuring 801,093 km2 that is now shared between 19 countries, from its source in the Black Forest to the Black Sea, into which it pumps an average of 827 km3 of water a year. This book describes and explains key landscape values interactions (geographical, cultural and natural heritage). It also identifies the threats and various types of human impact affecting this system in all the countries of the Danube River Basin, based on the investigations and perspectives of a team of experienced naturalists, and in the context of the early 21st century, in which the human-nature relationship is still far from balanced. These studies demonstrate how biodiversity, conservation and ecological studies can help us successfully promote mutual cooperation and combine our efforts to address problems as a responsible continent.

Download or read book Vaccines A Biography written by Andrew W. Artenstein and published by Springer Science & Business Media. This book was released on 2009-12-11 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why another book about vaccines? There are already a few extremely well-written medical textbooks that provide comprehensive, state-of-the-art technical reviews regarding vaccine science. Additionally, in the past decade alone, a number of engrossing, provocative books have been published on various related issues ra- ing from vaccines against specific diseases to vaccine safety and policy. Yet there remains a significant gap in the literature – the history of vaccines. Vaccines: A Biography seeks to fill a void in the extant literature by focusing on the history of vaccines and in so doing, recounts the social, cultural, and scientific history of vaccines; it places them within their natural, historical context. The book traces the lineage – the “biography” – of individual vaccines, originating with deeply rooted medical problems and evolving to an eventual conclusion. Nonetheless, these are not “biographies” in the traditional sense; they do not trace an individual’s growth and development. Instead, they follow an idea as it is conceived and dev- oped, through the contributions of many. These are epic stories of discovery, of risk-takers, of individuals advancing medical science, in the words of the famous physical scientist Isaac Newton, “by standing on the shoulders of giants. ” One grant reviewer described the book’s concept as “triumphalist”; although meant as an indictment, this is only partially inaccurate.
Download or read book The Sava River written by Radmila Milačič and published by Springer. This book was released on 2014-11-05 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a comprehensive overview of environmental aspects of the Sava River, which is the greatest tributary to the Danube River and the major drainage river system of South Eastern Europe. Hydroelectric power plants, river traffic, intensive agricultural activities, heavy industry and floods have considerable influence on the environment and biota in the basin. Summarizing the results that were gathered in the course of EU, bilateral and national projects, the book highlights the most important stressors and helps readers to better understand the impact of anthropogenic activities on the function of river basins. Topics include: transboundary water cooperation between the riparian countries; climate change projection, including its impact on flood hazards; evaluation of anthropogenic pollution sources; pollution of sediments, metal bioavailability and ecotoxicological and microbiological characterization of the river. The biological part also addresses quality aspects related to wildlife in river aquatic ecosystems (algae, macrophytes, zooplankton, macroinvertebrates and fish) and riparian ecosystems (amphibians, reptiles, birds and mammals). The general state of biodiversity and pressures caused by invasive aquatic species are also discussed.
Download or read book Science History and Social Activism written by Garland E. Allen and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: "To earn a degree, every doctoral candidate should go out to Harvard Square, find an audience, and explain his [or her] dissertation". Everett Mendelsohn's worldly advice to successive generations of students, whether apocryphal or real, has for over forty years spoken both to the essence of his scholarship, and to the role of the scholar. Possibly no one has done more to establish the history of the life sciences as a recognized university discipline in the United States, and to inspire a critical concern for the ways in which science and technology operate as central features of Western society. This book is both an act of homage and of commemoration to Professor Mendelsohn on his 70th birthday. As befits its subject, the work it presents is original, comparative, wide-ranging, and new. Since 1960, Everett Mendelsohn has been identified with Harvard Univer sity, and with its Department of the History of Science. Those that know him as a teacher, will also know him as a scholar. In 1968, he began- and after 30 years, has just bequeathed to others - the editorship of the Journal of the History of Biology, among the earliest and one of the most important publications in its field. At the same time, he has been a pioneer in the social history and sociology of science. He has formed particularly close working relationships with colleagues in Sweden and Germany - as witnessed by his editorial presence in the Sociology of Science Yearbook.
