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 Microbial Ecology of Arid Terrestrial Systems written by Thulani P. Makhalanyane and published by Frontiers Media SA. This book was released on 2016-09-14 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is usually referred to as the ‘Molecule of Life’. It constitutes the most abundant molecule in living (micro)organisms and is also essential for critical biochemical reactions, both for the global functioning and maintenance of Ecosystems (e.g., Photosynthesis) and individual (microbial) cells (e.g., ATP hydrolysis). However, most of Earth’s terrestrial environments present deficiencies in bioavailable water. Arid environments cover around a third of the land’s surface, are found on the six continents and, with the anthropogenic desertification phenomenon, will increase. Commonly defined by having a ratio of precipitation to potential evapotranspiration (P/PET) below 1, arid environments, being either hot or cold, are characterized by scant and erratic plant growth and low densities in macro-fauna. Consequently, these ecosystems are microbially mediated with microbial communities particularly driving the essential Na and C biogeochemical cycles. Due to the relatively simple trophic structure of these biomes, arid terrestrial environments have subsequently been used as ideal ecosystems to capture and model interactions in edaphic microbial communities. To date, we have been able to demonstrate that edaphic microorganisms (i.e., Fungi, Bacteria, Archaea, and Viruses) in arid environments are abundant, highly diverse, different from those of other terrestrial systems (both in terms of diversity and function), and are important for the stability and productivity of these ecosystems. Moreover, arid terrestrial systems are generally considered Mars-like environments. Thus, they have been the favored destination for astro(micro)biologists aiming to better understand life’s potential distribution and adaptation strategies in the Universe and develop terraforming approaches. Altogether, these points demonstrate the importance of significantly improving our knowledge in the microbial community composition (particularly for Fungi, Archaea and Viruses), assembly processes and functional potentials of arid terrestrial systems, as well as their adaptation mechanisms to aridity (and generally to various other environmental stresses). This Research Topic was proposed to provide further insights on the microbial ecology of hot and cold arid edaphic systems. We provide a detailed review and nine research articles, spanning hot and cold deserts, edaphic, rhizospheric, BSC and endolithic environments as well as culture-dependent and -independant approaches.

Download or read book Lead in Plants and the Environment written by Dharmendra K. Gupta and published by Springer Nature. This book was released on 2019-10-24 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the way that lead enters the biosphere and the subsequent environmental impact. The contributing authors include international experts who provide methods for assessing and characterizing the ecological risk of lead contamination of soil and plants. Information is provided on the consequences for human health as a result of lead pollution. This book reveals that approximately 98% of stable lead in the atmosphere originates from human activities. Lead in Plants and the Environment reports on methods for detecting, measuring, and assessing the concentration of lead in plants. The authors provide a method for the measurement of 210Pb isotopes in plants. This method can be applied extensively in different environmental settings, not only as a way of revealing sources of lead, but also as a way to monitor lead transport in plants and animals that ingest them. The chapters include coverage on the following topics: · Lead bioavailability in the environment and its exposure and effects · Radioanalytical methods for detecting and identifying trace concentrations of lead in the environment · Lead contamination and its dynamics in soil plant systems · Lead pollution monitoring and remediation through terrestrial plants in mesocosm constructed wetlands · A review of phytoremediation of lead This book is a valuable resource to students, academics, researchers, and environmental professionals doing field work on lead contamination throughout the world.

Download or read book The Biology of Arid Soils written by Blaire Steven and published by Walter de Gruyter GmbH & Co KG. This book was released on 2017-07-24 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils have been called the most complex microbial ecosystems on Earth. A single gram of soil can harbor millions of microbial cells and thousands of species. However, certain soil environments, such as those experiencing dramatic change exposing new initial soils or that are limited in precipitation, limit the number of species able to survive in these systems. In this respect, these environments offer unparalleled opportunities to uncover the factors that control the development and maintenance of complex microbial ecosystems. This book collects chapters that discuss the abiotic factors that structure arid and initial soil communities as well as the diversity and structure of the biological communities in these soils from viruses to plants.
