Book Synopsis Tropical Ecological Systems by : F.B. Golley
Download or read book Tropical Ecological Systems written by F.B. Golley and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1971 the International Society of Tropical Ecology and the International Association for Ecology held a meeting on Tropical Ecology, with an emphasis on organic production in New Delhi, India. At this meeting a Working Group on Tropical Ecology was organized, consisting of K. C. Misra (India), F. Malaisse (Zaire), E. Medina (Venezuela) and F. Golley (U.S.A.). The object of this Working Group was to stimulate interaction between tropical ecologists through future scientific meetings and other exchanges and communications. A second meeting of ISTE and INTECOL was held in Caracas, Venezuela in 1973, under the direction of Medina and Golley and sponsored by the Depart ment of Ecology, Institute Venezolano Investigaciones Cientificas (lVIC). The basic structure of the meeting was provided by series of invited papers which considered topics of special interest from both an applied and theoretical view. These included physiological ecology (Pannier), populations (Rabinovich), tropical savannas (Lamotte), rivers (Sioli), estuaries (Rodriguez), and island ecosystems (Mueller-Dombois). Contributed papers considered details of these and other ecological topics, including the application of ecology to human problems. The present volume includes the invited papers listed above and a sampling of contributed papers which together illustrate the trends of research in tropical ecology. The papers show that tropical ecology is a vigorous subject of research. While the papers in this volume do not provide reviews of all the topics of study in tropical ecology, they do present authoritative statements on progress in the major subject in the field.

Book Synopsis Diaspora Networks in International Business by : Maria Elo
Download or read book Diaspora Networks in International Business written by Maria Elo and published by Springer. This book was released on 2018-08-12 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: This contributed volume focuses on diasporans, their characteristics, networks, resources and activities in relation to international business and entrepreneurship. It presents an overview of diaspora concepts from an economic perspective, and analyzes the global-economic and societal effects and mechanisms, revealing both positive and negative aspects of diaspora activities. Providing insights into the socio-cultural influences, it discusses diaspora entrepreneurship and international business, the respective organisational models, investments and business types. Lastly it offers an assessment of managing diaspora resources and policymaking. This book was created by an interdisciplinary team of editors, co-authors and reviewers including historians, sociologists, psychologists, linguists and ethnologists, as well as experts in public policy, international business, marketing and entrepreneurship. This unique team (many of the authors are themselves diasporans with an extensive understanding of their topic) provides the first global academic platform on the subject, combining the latest empirical evidence from developing, emerging, transitional and developed countries with various combinations of diaspora flows that to date have received little attention.
Book Synopsis Coral Reefs and Climate Change by : Jonathan Turnbull Phinney
Download or read book Coral Reefs and Climate Change written by Jonathan Turnbull Phinney and published by American Geophysical Union. This book was released on 2006-01-10 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Coastal and Estuarine Studies, Volume 61. The effects of increased atmospheric carbon dioxide and related climate change on shallow coral reefs are gaining considerable attention for scientific and economic reasons worldwide. Although increased scientific research has improved our understanding of the response of coral reefs to climate change, we still lack key information that can help guide reef management. Research and monitoring of coral reef ecosystems over the past few decades have documented two major threats related to increasing concentrations of atmospheric CO2: (1) increased sea surface temperatures and (2) increased seawater acidity (lower pH). Higher atmospheric CO2 levels have resulted in rising sea surface temperatures and proven to be an acute threat to corals and other reef-dwelling organisms. Short periods (days) of elevated sea surface temperatures by as little as 1–2°C above the normal maximum temperature has led to more frequent and more widespread episodes of coral bleaching-the expulsion of symbiotic algae. A more chronic consequence of increasing atmospheric CO2 is the lowering of pH of surface waters, which affects the rate at which corals and other reef organisms secrete and build their calcium carbonate skeletons. Average pH of the surface ocean has already decreased by an estimated 0.1 unit since preindustrial times, and will continue to decline in concert with rising atmospheric CO2. These climate-related Stressors combined with other direct anthropogenic assaults, such as overfishing and pollution, weaken reef organisms and increase their susceptibility to disease.

Book Synopsis Biological Invasions in Europe and the Mediterranean Basin by : F. di Castri
Download or read book Biological Invasions in Europe and the Mediterranean Basin written by F. di Castri and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: In view of the massive change in the area of distribution of many world biota across classical biogeographical realms, and of the drastic restructuring of the biotic components of numerous ecosystems, the Scientific Committee on Problems of the Environment (SCOPE) decided at its general Assembly in Ottawa, Canada, in 1982 to launch a project on the 'Ecology of Biological Invasions'. Several regional meetings were subsequently organized within the framework of SCOPE, in order to single out the peculiarities of the invasions that took place in each region, the behaviour of their invasive species and the invasibility of their ecosystems. Most noteworthy among such workshops were one in Australia in August 1984, one concerning North America and Hawaii in October 1984, and one dealing with southern Africa in November 1985. A leitmotiv of these workshops was that most of the invasive species to those regions were emanating from Europe and the Mediterranean Basin, inadvertently or intentionally introduced by man. It was therefore considered as a timely endeavour to organize the next regional meeting in relation to this region. The workshop on 'Biological Invasions in Europe and the Mediterranean Basin' was held in Montpellier, France, 21 to 23 May 1986, thanks to the financial support of SCOPE and of the A.W. Mellon Foundation, and the logistic facilities of the Centre National de la Recherche Scientifique (C.N .R.S.).
Book Synopsis Developments in Environmental Modelling by : S.E. Jorgensen
Download or read book Developments in Environmental Modelling written by S.E. Jorgensen and published by Elsevier. This book was released on 2016-04-20 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of models to assess water quality is becoming increasingly important worldwide. In order to be able to develop a good model, it is necessary to have a good quantitative and ecological description of physical, chemical and biological processes in ecosystems. Such descriptions may be called ``submodels''. This book presents the most important, but not all, submodels applied in water quality modelling. Each chapter deals with a specific physical process and covers its importance, the most applicable submodels (and how to select one), parameter values and their determination, and future research needs.The book will be an excellent reference source for environmental engineers, ecological modellers and all those interested in the modelling of water quality systems.

Book Synopsis State of the World's Oceans by : Michelle Allsopp
Download or read book State of the World's Oceans written by Michelle Allsopp and published by Springer Science & Business Media. This book was released on 2008-12-16 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world’s oceans cover 70% of the earth’s surface and are home to a myriad of amazing and beautiful creatures. However, the biodiversity of the oceans is incre- ingly coming under serious threat from many human activities including overfi- ing, use of destructive fishing methods, pollution and commercial aquaculture. In addition, climate change is already having an impact on some marine ecosystems. This book discusses some of the major threats facing marine ecosystems by cons- ering a range of topics, under chapters discussing biodiversity (Chapter 1), fisheries (Chapter 2), aquaculture (Chapter 3), pollution (Chapter 4) and the impacts of increasing greenhouse gas emissions (Chapter 5). It goes on to explore solutions to the problems by discussing equitable and sustainable management of the oceans (Chapter 6) and protecting marine ecosystems using marine reserves (Chapter 7). Presently, 76% of the oceans are fully or over-exploited with respect to fishing, and many species have been severely depleted. It is abundantly clear that, in general, current fisheries management regimes are to blame for much of the widespread degradation of the oceans. Many policy-makers and scientists now agree that we must adopt a radical new approach to managing the seas – one that is precautionary in nature and has protection of the whole marine ecosystem as its primary objective. This ‘ecosystem-based approach’ is vital if we are to ensure the health of our oceans for future generations.

Book Synopsis Pastoralism and Socio-technological Transformations in Northern Benin by : Georges Djohy
Download or read book Pastoralism and Socio-technological Transformations in Northern Benin written by Georges Djohy and published by Göttingen University Press. This book was released on 2017 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pastoralists throughout Africa face increasing pressures. In Benin, governmental development policies and programmes in crop farming are changing power relations between herders and farmers to favour the latter. How are the Fulani pastoralists responding to these threats to their existence? Georges Djohy explores the dynamics in local use of natural resources and in inter-ethnic relations resulting from development interventions. He combines the approaches of science and technology studies – looking at the co-construction of society and technology – and political ecology – looking at the power relations shaping the dynamics of economic, environmental and social change – so as to throw light on the forces of marginalisation, adaptation and innovation at work in northern Benin. Having worked there for many years, Djohy has been able to uncover gradual processes of socio-technological change that are happening “behind the scenes” of agricultural development involving mechanisation, herbicide use, tree planting, land registration and natural resource conservation. He reveals how farmers are using these interventions as “weapons” in order to gain more rights over larger areas of land, in other words, to support indigenous land grabbing from herders who had been using the land since decades for grazing. He documents how the Fulani are innovating to ensure their survival, e.g. by using new technologies for transport and communication, developing new strategies of livestock feeding and herd movement, and developing complementary sources of household income. The Fulani are organising themselves from local to national level to provide technological and socio-cultural services, manage conflicts and gain a stronger political voice, e.g. to be able to achieve demarcation of corridors for moving livestock through cultivated areas. They even use non-functioning mini-dairies – another example of development intervention – to demonstrate their modernity and to open up other opportunities to transform their pastoral systems. This book provides insights into normally hidden technical and social dynamics that are unexpected outcomes of development interventions.
