Download or read book Key to Parasitic Nematodes written by Skryabin and published by BRILL. This book was released on 2023-10-09 with total page 1109 pages. Available in PDF, EPUB and Kindle. Book excerpt: This final volume in the treatise Keys to Parastic Nematodes is devoted to the characters of five suborders of nematodes, compiled by five specialists. Suborder Trichocephalata and Diotophymata were compiled by K.I. Skryabin and N.P. Shikhobalova, and Rhabditata and Tylenchata by A.A. Sobolev and A.A. Paramonov. A.A. Sobolev analyzed the material on Camallanta, while V.E. Sudarikov compiled the chapter on the distribution of all known nematodes in different hosts recorded thus far, for all four volumes of this key. The importance of this volume is enhanced further by the most comprehensive index of animal hosts of all known parasitic nematodes reviewed. This comprehensive work is the first of its kind in helminthological literature; this type of treatise has never before been published in any country to date.

Download or read book Identification Guide of Freshwater Macroinvertebrates of Spain written by Javier Oscoz and published by Springer Science & Business Media. This book was released on 2011-06-27 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a result of the European Commission’s concern for the status of continental waters, and as a clear reflection of the notion of water as heritage to be conserved, in the year 2000 the Water Framework Directive (2000/60/CE) was enacted, its goal being to establish a framework to protect water and the different aquatic ecosystems by requiring the Member States to achieve a good ecological status in all their waters by 2015. Like all ecosystems, freshwater ecosystems undergo physical, chemical and energy-related changes, both of natural and anthropogenic origin. These disturbances affect the organisms living in them and those who utilize their resources. Therefore, evaluating these changes has become a very important task in order to better understand aquatic systems. The study and analysis of the ecological status of these ecosystems in relation to their conservation status and water quality is thus a fundamental tool for a more efficient and rational management of their resources, that is, a management that does not threaten the ecosystem. The present guide for the identification of Spanish freshwater macroinvertebrates aims to facilitate the job of those who go to great lengths to identify them in order to then determine biotic indices. It is not the aim of this book to serve as a zoological treaty, nor does it claim to add new information on the biology or the ecology of the taxa covered. This book is, simply, a working tool explicitly designed to facilitate the identification of the Spanish macroinvertebrates and the subsequent computing of biotic indices.

Download or read book Alboran Sea Ecosystems and Marine Resources written by José Carlos Báez and published by Springer Nature. This book was released on 2021-05-22 with total page 942 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alboran Sea represents a regional Mediterranean space where North and South worlds merges, creating a geopolitical region where marine resources and maritime activities should be managed from a national and international perspectives. It is widely known, that currently the planet is suffering a global change, and it is also affecting the Alboran Sea, its ecosystems and populations. An important first step to update a paramount vision on this region is to understand the climatic, geologic and oceanographic, including biochemical cycles, process which shapes the rich geodiversity, biodiversity, the productivity, and the sustainable use of the marine resources from Alboran Sea. The fisheries management system should take into account marine environmental variability to achieve biological sustainability of marine resources. Well-funded policy-makers’ decisions require a sound science based knowledge of the interaction between the marine environment and commercial stocks. This is because the role of marine environment in the evolution of fish stocks is sometimes even more important than the one played by fishers in the commercial exploitation of them. Finally, we should analyze the different aspects of political context that could affect the management of the resources from Alboran Sea in the context of climate change. This book reviews different aspects of the Alboran Sea to help understand the current situation from the original Tethis Ocean. The book is divided into four blocks: (i) Oceanographic, geological and ecological context (chapters 2 to 7), (ii) biodiversity and ecosystems distribution (chapters 8 to 12), (iii) fisheries resources and aquaculture (chapters 13 to 20), and (iv) conservation, management and marine polices (chapters 21 to 25).

Book excerpt: For public and school libraries, this resource reflects recent changes in Library of Congress subject headings and authority files, and provides bilingual information essential to reference librarians and catalogers serving Spanish speakers. Libraries must provide better access to their collections for all users, including Spanish-language materials. The American Library Association has recognized this increasing need. Subject Headings for School and Public Libraries: Bilingual Fourth Edition is the only resource available that provides both authorized and reference entries in English and Spanish. A first-check source for the most frequently used headings needed in school and public libraries, this book incorporates thousands of new and revised entries to assist in applying LCSH and CSH headings. Of the approximately 30,000 headings listed, most include cross-references, and all of the cross-reference terms are translated. MARC21 tags are included for all authorized entries to simplify entering them into computerized catalogs, while indexes to all headings and free-floating subdivisions are provided in translation from Spanish to English. This book gives librarians access to accurate translations of the subject terms printed in books published and cataloged in English-speaking countriesinvaluable information in settings with Spanish-speaking patrons.

Download or read book Invasive Alien Species written by Michael R. Ielmini and published by John Wiley & Sons. This book was released on 2021-04-21 with total page 1488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jedes Jahr breiten sich invasive gebietsfremde Arten in neue Ökosysteme aus. Die von den Eindringlingen verursachten Auswirkungen können sich in kürzester Zeit bemerkbar machen und verheerend sein. Das Thema der invasiven gebietsfremden Arten ist umfassend, komplex und auf verschiedenen Ebenen von globaler Bedeutung. Verschärft wird es durch die Globalisierung der Weltwirtschaft und den zunehmenden Handel, durch den die natürlichen Barrieren für den Transfer von Arten durchbrochen werden. Invasive gebietsfremde Arten bedrohen die weltweite Nahrungsmittelversorgung, die Qualität und Verfügbarkeit von Trinkwasser sowie die Stromproduktion und -versorgung. Zusammen mit den zusätzlichen Risiken durch den globalen Klimawandel ist die weltweite Homogenisierung von Pflanzen, Tieren und Mikroben ein wesentlicher Faktor für den sich verschlechternden Gesundheitszustand der Ökosysteme und die nachlassenden Ökosystemdienstleistungen überall auf der Welt. Um dieser Entwicklung entgegenzuwirken, besteht die dringende Notwendigkeit einer einheitlichen Ausrichtung von Regierungen, Kulturen und Programmen und einer besseren grenzüberschreitenden Koordination. Nur so lassen sich die vielfältigen Bedrohungen durch invasive gebietsfremde Arten für die Umwelt, die Wirtschaft und die Gesundheit von Pflanzen und Tieren sowie insbesondere die menschliche Gesundheit effektiv bekämpfen. Dieses vierbändige Werk ist das erste, das einen umfassenden Satz nützlicher Materialien zu den zentralen Themen bereitstellt, um die gesamte globale Bedrohung durch invasive gebietsfremde Arten sowie die vielfältigen Probleme in verschiedenen Teilen der Welt deutlich zu machen, und es enthält Material, in dem potenziell replizierbare Lösungen zur Überwindung dieser Bedrohungen aufgezeigt werden. Das Werk betont die Bedrohung durch invasive gebietsfremde Arten auch im Sinne eines globalen ?Aufrufs zum Handeln?. Invasive Arten kennen keine Grenzen. Daher hoffen wir, dass wir durch die Zusammenstellung von Material, das unterschiedliche wissenschaftliche und gesellschaftliche Standpunkte aus aller Welt berücksichtigt, sowie durch die Vermittlung von Erkenntnissen und Beispielen zu einer Vielzahl damit zusammenhängender Themen das globale Bewusstsein stärken und einheitliche nationale Reaktionen auf die Bedrohung durch invasive gebietsfremde Arten fördern können.
