Download or read book Tropical Stream Ecology written by David Dudgeon and published by Elsevier. This book was released on 2011-05-04 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical Stream Ecology describes the main features of tropical streams and their ecology. It covers the major physico-chemical features, important processes such as primary production and organic-matter transformation, as well as the main groups of consumers: invertebrates, fishes and other vertebrates. Information on concepts and paradigms developed in north-temperate latitudes and how they do not match the reality of ecosystems further south is expertly addressed. The pressing matter of conservation of tropical streams and their biodiversity is included in almost every chapter, with a final chapter providing a synthesis on conservation issues. For the first time, Tropical Stream Ecology places an important emphasis on viewing research carried out in contributions from international literature. - First synthetic account of the ecology of all types of tropical streams - Covers all of the major tropical regions - Detailed consideration of possible fundamental differences between tropical and temperate stream ecosystems - Threats faced by tropical stream ecosystems and possible conservation actions - Descriptions and synstheses life-histories and breeding patterns of major aquatic consumers (fishes, invertebrates)

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.

Download or read book National System Planning for Protected Areas written by Adrian G. Davey and published by IUCN. This book was released on 1998 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: A system plan is the design of a total reserve system covering the full range of ecosystems and communities found in a particular country, identifying the range of purposes of protected areas and the relationships among the system components (i.e., individual areas, protected areas and other land uses), and different sectors and levels of society. Highlighting key linkages with other aspects of economic development, it shows how various stakeholders can interact and cooperate to support effective and sustainable management of protected areas, and help to establish priorities. A valuable resource for all those involved with national system planning.
Download or read book Microbial Taxonomy Phylogeny and Biodiversity written by Jesús L. Romalde and published by Frontiers Media SA. This book was released on 2019-12-31 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: The great diversity of microbial life is the remaining major reservoir of unknown biological diversity on earth. To understand this vast, but largely unperceived diversity with its untapped genetic, enzymatic and industrial potential, microbial systematics is undergoing a revolutionary change in its approach to describe novel taxa based on genomic/envirogenomic information. The characterization of an organism is no longer bounded by methodological barriers, and it is now possible to fully sequence the whole genome of a strain to study individual genes, or to examine the genetic information by using different techniques. In fact, application of genomics is helping not only to provide a better understanding of the boundaries of genera and higher levels of classification, but also to refine our definition of the species concept. In addition, increased understanding of phylogeny is allowing to predict the genetic potential of microorganisms for biotechnological applications and adaptation to environmental changes. The present Research Topic on “Microbial Taxonomy, Phylogeny and Biodiversity” compiles a collection of papers covering the use of genomic sequence data in microbial taxonomy and systematics, including evolutionary relatedness of microorganisms; application of comparative genomics in systematic studies; or metagenomic approaches for biodiversity studies. We hope that this eBook incentives and encourages researchers for future discussions on microbial taxonomy and phylogenetics.

Download or read book The Andes written by Axel Borsdorf and published by Springer. This book was released on 2015-03-12 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Andes are attracting global interest again: they hold valuable mineral resources, tourists appreciate their great natural beauty and the diversity of indigenous cultures, climbers scale rock and ice faces, while many others are intrigued by regional political developments, such as the Bolivarian revolution in Venezuela or the almost unfettered hegemony of the neoliberal economic model in Chile. This volume is the first attempt for decades to present a complete overview of the longest mountain chain on the planet – a region of remarkable climatic, floristic and geologic diversity, where advanced civilization developed well before the arrival of the Spanish. Today the Andes continue to be characterized by their ethnic, demographic, cultural and economic diversity, as well as by the disparity of local socioeconomic groups. The Andean countries pursue a wide range of approaches to tackle the challenges of making the best use of their natural and cultural potential without damaging their ecological basis, as well as to overcome economic disparity and foster social cohesion. This book provides insights into this unique region and its most pressing issues, complemented by a wealth of pictures and comprehensive diagrams, which, in sum, help to better understand these fascinating mountains.
