This book was released on 2012-12-06 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: The identification of inputs and outputs is the first and probably most important step in testing and analyzing complex systems. Following accepted natural laws such as the conservation of mass and the principle of electroneutrality, the input/output analysis of the system, be it steady or in connection with perturbations will reveal the status dynamic, will identify whether changes are reversible or irreversible and whether changing the input will cause a hysteresis response. Moreover, measurements ofinput and output fluxes can indicate the storage capacity ofa system, its resilience to buffer or amplify variations of the external input, and it can identify structural changes. Therefore, to a certain extent, the input/output analysis can facilitate predictions about the ecosystem stability. The measurement of fluxes and the determination of inputs and outputs of eco systems are, in many aspects, analogous to measurements done by engineers when testing an electronic apparatus. The first step is the measurement ofthe input/output properties of the instrument as a whole, or ofvarious circuit boards, and the compari· son ofthese with the expected variations of the original design. Varying input and out· put can give valuable information about the stability and the regulatory properties of the device. Nevertheless, only the circuit as an entity has specific properties which cannot be anticipated if the individual components are investigated regardless oftheir position. Also, the instrument as a whole will have different input/output properties than its subcircuits.

This book was released on 2013-12-01 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1996 a major six-year research programme, 'Economic Optimisation of Multiple-Use Forestry and Other Natural Resources' was implemented at Department of Economics and Natural Resources, The Royal Veterinary and Agricultural University (KVL), Copenhagen. The research is funded by KVL; The Danish Agricultural and Veterinary Research Council; The Danish Research Academy; The Danish Forest and Landscape Institute; The Danish Forest and Nature Agency; and The Danish Environmental Protection Agency. The overall objective of the research programme is to enhance the economic theory of sustainable multiple-use forestry and landscape management planning. Emphasis is on decision-making ! management planning from an economic point of view, the basic criterion being rationality as implemented by application of Operations Research methods with regard to sustainable and multiple use of forests and other natural resources in the landscape. The research programme benefits from collaboration agreements with University of California at Berkeley, Department of Agricultural and Resource Economics, and Oregon State University, Department of Forest Resources. As part of the research programme, a second international conference and workshop was held 6 - 12 August, 1998 at KVL, with the title: '2nd Berkeley-KVL Conference on Natural Resource Management -Design and Implementation of Multiple-Use Management'. This event was financed by The Danish Research Academy. Some of the papers presented were selected for peer-reviewing and subsequent publishing. The outcome is the present book in which no paper has been previously published.

This book was released on 2013-03-13 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Is ecology at a crossroad? After three decades of rapid, though somewhat anarchic development, many ecologists now are beginning to ask this question. They have the feeling of no longer belonging to a unified and mature scientific discipline. Many of them claim to be mere empiricists, whereas others are proud to be considered theoreticians. Each side has its own journals and holds its own specialists' meetings, tending to disregard the achievements of the other. The communication gap between the two schools is quickly widening, to the detriment of both. To make things worse, the word "ecology" now has a different meaning for the professional biologists and the general public. Ecology is still considered as a creditable (though rather "soft") scientific discipline by the former, whereas it is perceived as a new, non-conformist political philosophy by the latter. Empirical ecologists are fundamentally naturalists who enjoy the immense complexity of the natural world and devote their lifetimes to the description of the many adaptive characteristics--morpholog ical, biological, or behavioral--of the hundreds of thousands of species sharing the earth with us. They generally are ignorant of, if not allergic to, the use of any mathematical representation of living phenomena. They' feel that ecological theory is rapidly becoming a mathematical game that has lost any contact with the "realities of life.

This book was released on 2013-03-09 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume summarises the result of an interdisciplinary research programme entitled `Rehabilitation of the Atmosphere of the New States of Germany - Effects on Terrestrial Ecosystems'. Before the unification of Germany, emission loads of SO2 and dust particles were up to 18-fold higher in East than in West Germany. However, emission rates have decreased significantly since reunification in 1990, due to the breakdown of a large number of industrial and particularly lignite- fired powerplants and the implementation of clean air technologies. In order to study the effects of these dramatic changes in atmospheric chemistry on terrestrial ecosystems, comprehensive field studies were conducted in pine forest ecosystems along an historic gradient of atmospheric deposition rates in the northeastern lowlands of Germany. The fast and dramatic reduction of dust particle and SO2 emissions offers a unique opportunity to test the role of SO2 and alkaline particle deposition with regard to changes or damage to forest ecosystems and whether the forest stands return to a state of resilience. In this respect, this ecosystem experiment can be looked upon as a roof experiment without a roof.
Download or read book Theoretical Ecosystem Ecology written by Goran I. Agren and published by Cambridge University Press. This book was released on 1998-07-13 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cycling of elements such as carbon and nitrogen is of central importance in ecology, particularly when humans are causing changes to element cycles on a global scale. In this 1996 book a rigorous mathematical framework is developed to model how element cycles operate and interact in plants and soils, forming the foundations of a new ecosystem theory. From a few basic equations, powerful predictions can be generated covering a wide range of ecological phenomena related to element cycling. These predictions are tested extensively against field and laboratory studies of agricultural and forest ecosystems. This work will be of interest to graduate students and researchers in theoretical ecology, soil science, forestry and biogeochemistry.

Download or read book From Ethnomycology to Fungal Biotechnology written by Jagjit Singh and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fungi playa major role in the sustainability of the biosphere, and mycorrhizal fungi are essential for the growth of many of our woods and forests. The applications of fungi in agriculture, industry and biotechnology remain of paramount importance, as does their use as a source of drugs and to help clean up our environment. This volume contains key papers from the conference 'From Ethnomycology to Fungal Biotechnology: Exploiting Fungi from Natural Resources for Novel Products'. This was the first international scientific conference covering the transfer of traditional remedies and processes in ethnomycology to modern fungal biotechnology. The conference was held at Simla, Himachal Pradesh, India from 15 to 16 December 1997. The key subject areas addressed in the conference were the issues of exploring and exploiting fungal diversity for novel leads to new antibiotics, enzymes, medicines and a range of other leads for wood preservation, biological control, agricultural biotechnology and the uses of fungi in the food industry. The conference programme included key-note presentations followed by poster sessions and general discussion. The book is broadly based, covering five main areas: Ethnomycology, Fungal Biotechnology, Biological Control, Mycorrhizal Fungi and Fungal Pests. There is no doubt that in the past fungi have played a key role in ethnomycological remedies and that in the future they will continue to attract the interest of a wide range of disciplines ranging from environmental conservation, agriculture and the food industry to wood preservation and aerobiological studies.
