Book Description
With a population of more than eighteen million people, Mexico City is a major metropolitan area where the effects of urban development on air quality are of immediate concern. Air pollution exposures and effects on forests in the Mexico City Air Basin are in many respects similar to those reported in the Los Angeles, California Air Basin. Studies of air pollution impacts on forests in these two regions may serve as models for urban areas all over the world. Although scientists have studied air pollution and its effects on forests and vegetation in the Mexico City Air Basin for years, this book reviews and synthesizes this body of work for the first time. This synthesis is particularly valuable as air pollution increases at an alarming rate along with global urbanization. A thorough discussion of regional geology, climate and hydrology, historical natural resource utilization, and sociological factors provide the context for evaluating air pollution impacts on the highly valued forests surrounding this megacity. The environmental and ecological consequences of chronic exposure to biologically important pollutants are considered in various case studies. Finally, the editors discuss the state of air pollution research in the Mexico City Air Basin and the outlook for the health and sustainability of forests within the Basin.

Book Description
Soil is a complex body that exists as many types, each with diverse properties that may vary widely across time and space as a function of many factors. This complexity makes the evaluation of soil quality much more challenging than that of water or air quality. Evaluation of soil quality now considers environmental implications as well as economic productivity, seeking to be more holistic in its approach.Thus, soil quality research draws from a wide range of disciplines, blending the approaches of biologists, physicists, chemists, ecologists, economists and agronomists, among others.This book presents a broad perspective of soil quality that includes these various perspectives and gives a strong theoretical basis for the assessment of soil quality.A short glossary provides definitions for terms used throughout the book.

Book Description
This monograph presents the state of art of the geologic knowledge about the Spanish coast obtained through scientific research in the last 30 years.From a general point of view, coasts are the most quickly changing systems of the Earth. This is critical, since many human resources, such as the main part of economic and social activities, are located in the coastal areas. Especially in the case of Spain these coasts include cities, wide industrial areas (including harbor complexes), important ecologic systems, and our main economic resource: tourism. Understanding the dynamic functioning of each element of this coast is vital for correct future coastal management, so as to solve problems derived from bad plans developed in the last decades of the twentieth century. This is a valuable text for advanced graduate students and coastal researchers, which connects the specific dynamic functioning of the main Spanish coastal environments and their relationships with human activities.

Book Description
Gathered to meet the rising upsurge of interest in Spain, this collection features major critical articles dealing with the authors and texts customarily taught in colleges and universities in the United States. The articles are in English and Spanish, with a predominance of the former. The material is organized to reflect the common chronological and period divisions of the academic curriculum, and is clustered around major literary figures, with a mix of general articles on the writers and texts that are most commonly included in anthologies. Spanish literature and culture have attracted a renewed interest since the return to constitutional democracy in the mid-1970s and the growing participation of Spain in the world economy and its incorporation into the European common market. Spanish literature balances a participation in the major literary movements of European literature in general with unique features of Hispanic culture that are a consequence of the special circumstances of its geography,especially the ways in which it historically served as a conduit to Europe of Arabic and Jewish cultures. Figures of international acclaim like Federico Garc'a Lorca, Miguel de Unamuno, and Jose Ortega y Gasset, Nobel prizewinners like Vicente Aleixandre and Camilo Jose Cela, the universality of Miguel de Cervantes, without whom the modern novel would not have been possible, the uniqueness of the Hispanic ballad tradition, mystic poets like San Juan de la Cruz and Santa Teresa Jesus, and the picaresque tradition are some of the major reference points for the singularity of Spanish literary culture. All of this literary activity has inspired innumerable dissertations, theses, and books, published by academic and trade presses, as well as articles in journals traditionally devoted to literary history and philosophy, along with new specialized journals and the organization of national and international congresses on national and cultural issues, writers, and schools of writing. These three volumesselect the most seminal works on Spanish literature and collect them in one place for scholars and students alike. This three volume collection of reprinted articles is also available as individual volumes priced at $80.00/Y [Can. $120.00/Y]: * Volume 1.Theoretical Debates0815335636 Volume 2.From Origins to the 18th Century0815335644 Volume 3.The Modern Period0185335652

Book Description
Cork oak has historically been an important species in the western Mediterranean—ecologically as a canopy or “framework” tree in natural woodlands, and culturally as an economically valuable resource that underpins local economies. Both the natural woodlands and the derived cultural systems are experiencing rapid change, and whether or not they are resilient enough to adapt to that change is an open question. Cork Oak Woodlands on the Edge provides a synthesis of the most up-to-date, scientific, and practical information on the management of cork oak woodlands and the cultural systems that depend on cork oak. In addition, Cork Oak Woodlands on the Edge offers ten site profiles written by local experts that present an in-depth vision of cork oak woodlands across a range of biophysical, historical, and cultural contexts, with sixteen pages of full-color photos that illustrate the tree, agro-silvopastoral systems, products, resident biodiversity, and more. Cork Oak Woodlands on the Edge is an important book for anyone interested in the future of cork oak woodlands, or in the management of cultural landscapes and their associated land-use systems. In a changing world full of risks and surprises, it represents an excellent example of a multidisciplinary and holistic approach to studying, managing, and restoring an ecosystem, and will serve as a guide for other studies of this kind.

Book Description
It has become clear that soil water repellency is much more wide-spread than formerly thought. Water repellency has been reported in most continents of the world for varying land uses and climatic conditions. Soil water repellency often leads to severe runoff and erosion, rapid leaching of surface-applied agrichemicals, and losses of water and nutrient availability for crops. At present, no optimum management strategies exist for water repellent soils, focusing on minimizing environmental risks while maintaining crop production. The book starts with a historical overview of water repellency research, followed by seven thematic sections covering 26 research chapters. The first section discusses the origin, the second the assessment, and the third the occurrence and hydrological implications of soil water repellency. The fourth section is devoted to the effect of fire on water repellency, section five deals with the physics and modeling of flow and transport in water repellent soils, section six presents amelioration techniques and farming strategies to combat soil water repellency, and section seven concludes the book with an extensive bibliography on soil water repellency.

Book Description
South American ecosystems suffered one of the greatest biogeographical events, after the establishment of the Panamian land bridge, called the “Great American Biotic Interchange” (GABI). This refers to the exchange, in several phases, of land mammals between the Americas; this event started during the late Miocene with the appearance of the Holartic Procyonidae (Huayquerian Age) in South America and continues today. The major phases of mammalian dispersal occurred from the Latest Pliocene (Marplatan Age) to the Late Pleistocene (Lujanian Age). The most important and richest localities of Late Miocene-Holocene fossil vertebrates of South America are those of the Pampean region of Argentina. There are also several Late Miocene and Pliocene localities in western Argentina and Bolivia. Other important fossils have been collected in localities of Pleistocene age outside Argentina: Tarija (Bolivia), karstic caves of Lagoa Santa and the recently explored caves of Tocantins (Brasil), Talara (Perú), La Carolina (Ecuador), Muaco (Venezuela), and Cueva del Milodon (Chile), among others. The book discusses basic information for interpreting the GABI such as taxonomic composition (incorporating the latest revisions) at classical and new localities for each stage addressing climate, environments, and time boundaries for each stage. It includes the chronology and dynamics of the GABI, the integration of South American mammalian faunas through time, the Quaternary mammalian extinctions and the composition of recent mammalian fauna of the continent.
