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 Subject Headings for School and Public Libraries written by Joanna F. Fountain and published by Bloomsbury Publishing USA. This book was released on 2012-01-16 with total page 487 pages. Available in PDF, EPUB and Kindle. 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 Animal Life in Fresh Water written by Helen Mellanby and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: by Professor L. E. Eastham Formerly Professor of Zoology in the University of Sheffield Most books are written with the intention of supplying some particular need, but few end with such single purpose. Mrs. Mellanby's is no exception, for while the author planned this work to serve as a guide to the school pupil, which function it fulfils in an admirable way, it will also prove of value to the teacher, the university student and the amateur naturalist. While it may be argued that it is not the function of the Uni versities to teach Natural History in the commonly accepted sense, it will always be the aim of Zoologists to know more about animals, what they are and do, where they live and why they live in particular environments. It is unfortunate, in view of the fact that the majority of students of Zoology enter the teaching pro fession, that the increasing load of instruction in morphology, physiology, cytology, genetics, evolution and the like frequently makes a personal study of animal life in relation to environment almost impossible. The fortunate ones visit the sea for a fort night's course in Marine Ecology; the others take posts in schools without even this respite and set about converting their academic learning to a school curriculum. The result is an undesirable and often slavish imitation of university method in the school class room.
