Download or read book Hyaenas written by M. G. L. Mills and published by World Conservation Union. This book was released on 1998 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite their low species density, hyenas are both unique and vital components of most African and some Asian ecosystems. Although there are only 4 species, they tend to clash with the interests of humans to a greater extent than many other mammals and one of the biggest obstacles facing those committed to the conservation of this species is the negative feelings that many people have towards hyenas. This action plan sets out to address some of the problems facing this species of animal, particularly the issue of public perception and awareness, and provides guidelines to rectify this situation.
Book Synopsis Night Noise Guidelines for Europe by : Charlotte Hurtley
Download or read book Night Noise Guidelines for Europe written by Charlotte Hurtley and published by WHO Regional Office Europe. This book was released on 2009 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: The WHO Regional Office for Europe set up a working group of experts to provide scientific advice to the Member States for the development of future legislation and policy action in the area of assessment and control of night noise exposure. The working group reviewed available scientific evidence on the health effects of night noise, and derived health-based guideline values. In December 2006, the working group and stakeholders from industry, government and nongovernmental organizations reviewed and reached general agreement on the guideline values and key texts for the final document of the "Night noise guidelines for Europe". Considering the scientific evidence on the thresholds of night noise exposure indicated by "Lnight,outside" [L suffix night,outside] as defined in the Environmental Noise Directive (2002/49/EC), an Lnight, outside of 40 dB should be the target of the night noise guideline (NNG) to protect the public, including the most vulnerable groups such as children, the chronically ill and the elderly. "Lnight,outside" value of 55 dB is recommended as an interim target for the countries where the NNG cannot be achieved in the short term for various reasons, and where policy-makers choose to adopt a stepwise approach. These guidelines are applicable to the Member States of the European Region, and may be considered as an extension to, as well as an update of, the previous WHO "Guidelines for community noise" (1999).

Book Synopsis National Parks and Protected Areas by : James Gordon Nelson
Download or read book National Parks and Protected Areas written by James Gordon Nelson and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: National parks and protected areas offer a wealth of ecological and social contributions or services to humans and life on earth. This book describes the strengths of national parks and protected areas in different parts of Europe and North America and the challenges to the full realization of their goals. It shows that they are useful not only in conserving rare species and biodiversity, but also in protecting water supply and other resources necessary to tourism and to economic and social development generally. Ideas and information on useful planning, management and decision-making arrangements are presented, and research needs are identified.

Book Synopsis Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments by : Elżbieta Kalisińska
Download or read book Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments written by Elżbieta Kalisińska and published by Springer. This book was released on 2019-03-01 with total page 707 pages. Available in PDF, EPUB and Kindle. Book excerpt: The population explosion that began in the 1960s has been accompanied by a decrease in the quality of the natural environment, e.g. pollution of the air, water and soil with essential and toxic trace elements. Numerous poisonings of people and animals with highly toxic anthropogenic Hg and Cd in the 20th century prompted the creation of the abiotic environment, mainly in developed countries. However, the system is insufficient for long-term exposure to low concentrations of various substances that are mainly ingested through food and water. This problem could be addressed by the monitoring of sentinels – organisms that accumulate trace elements and as such reflect the rate and degree of environmental pollution. Usually these are long-lived vertebrates – herbivorous, omnivorous and carnivorous birds and mammals, especially game species. This book describes the responses of the sentinels most commonly used in ecotoxicological studies to 17 trace elements.
Download or read book Heavy Metals written by Wim Salomons and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Heavy Metals: Problems and Solutions" is divided into three sections dealing with basic geochemical processes, remediation and case studies. The basic geochemical processes are discussed with respect to mobility in the environment and impact as well as methods to derive guidelines for heavy metals. Remediation focuses on currently available methods to treat contaminated sediments and soils. In addition, it considers the concept of geochemical engineering for remediation of large areas contaminated by metals. A number of case studies of polluted sediments and soils and their environmental impact highlight the principles discussed in the first two sections.

Book Synopsis Relict Species by : Jan Christian Habel
Download or read book Relict Species written by Jan Christian Habel and published by Springer Science & Business Media. This book was released on 2009-12-03 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mankind has evolved both genetically and culturally to become a most successful and dominant species. But we are now so numerous and our technology is so p- erful that we are having major effects on the planet, its environment, and the b- sphere. For some years prophets have warned of the possible detrimental consequences of our activities, such as pollution, deforestation, and overfishing, and recently it has become clear that we are even changing the atmosphere (e. g. ozone, carbon dioxide). This is worrying since the planet’s life systems are involved and dependent on its functioning. Current climate change – global w arming – is one recognised consequence of this larger problem. To face this major challenge, we will need the research and advice of many disciplines – Physics, Chemistry, Earth Sciences, Biology, and Sociology – and particularly the commitment of wise politicians such as US Senator Al Gore. An important aspect of this global problem that has been researched for several decades is the loss of species and the impoverishment of our ecosystems, and hence their ability to sustain themselves, and more particularly us! Through evolutionary time new species have been generated and some have gone extinct. Such extinction and regeneration are moulded by changes in the earth’s crust, atmosphere, and resultant climate. Some extinctions have been massive, particularly those asso- ated with catastrophic meteoric impacts like the end of the Cretaceous Period 65Mya.
Book Synopsis Conservation of Wood Artifacts by : A. Unger
Download or read book Conservation of Wood Artifacts written by A. Unger and published by Springer Science & Business Media. This book was released on 2001-08-29 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impetus for this book was the desire to systematically organize the extant literature on the conservation of cultural property made of wood, from its beginnings before the Christian Era to the year 2000. Various published reviews and monographs, including Holzkonservierung (Wood Conserva tion) published by the senior author in 1988, have appeared over the years, especially in English and in German. They have provided exemplary treat merit of individual areas or aspects of wood conservation, but a comprehen sive, up-to-date exposition of historic and current developments has been lacking. The diverse professional fields of the authors, as well as their insights into methods of conservation and restoration of wood artifacts in Europe, North America, and Asia provided a solid basis for the success of this under taking. One of the goals during the examination of the literature was that not only well-known conservators and scientists from countries that are leaders in wood conservation should be represented, but that less well-known, often not as readily accessible contributions should also be included. Only in this manner was it possible to draw a comprehensive picture of the national and international state of wood conservation. The Art and Archaeology Technical Abstracts (AATA) of the Getty Institute were very helpful in our efforts to evaluate as many publications as possible.
