Book excerpt: Los indices de calidad del agua dependen de caracteristicas fisicas, quimicas y bacteriologicas, propias de los ecosistemas acuaticos y que son evaluadas mediante el analisis de las muestras de agua; sin embargo, los valores obtenidos no son indices absolutos de contaminacion, sino que representan caracteristicas particulares del agua, en cuanto al parametro mismo. Asi, los Indices de Calidad de Agua, combinan una serie de variables o parametros del agua, generando una escala numerica representativa del grado de contaminacion del cuerpo de agua, el cual varia entre 0 (Agua muy contaminada) y 100 (Agua totalmente limpia). En este trabajo, el calculo del indice de calidad (ICA) se efectuo con los parametros utilizados por la NSF en su WQI: Coliformes fecales, pH, Solidos totales, DBO, OD, Fosfatos, Nitratos y Turbidez, segun describen diversos autores. Los principales parametros que afectaron al indice de calidad del agua en el Tecolutla fueron: DBO, coliformes totales, fosforo y nitratos, lo cual es indicador de contaminacion antropogenica. A partir de este estudio, se deben de retomar algunas recomendaciones para la gestion de este recurso en la cuenca del rio Tecolutla, Ver.

Available in PDF, EPUB and Kindle. Book excerpt: The indiscriminate use of chemical substances in industrial processes and anthropogenic activities, have resulted in the release of these compounds into aquatic ecosystems through municipal, hospital and industrial discharges, producing various undesired effects on the environment and on species of ecological interest. These compounds, such as metals, pesticides, emerging pollutants and other substances are persistent and susceptible to biotic and/or abiotic transformations, yielding metabolites that can be more toxic than the original compounds. In this book, researchers from diverse environmental science disciplines share their experiences in countries such as Argentina, Brazil, Colombia and Mexico, and critically examine the problem of contaminants in aquatic ecosystems in Latin America, as well as the risks presented by their presence.

Available in PDF, EPUB and Kindle. Book excerpt: Mexico is an extensive country with an extremely complex mosaic of landscapes. The soils of Mexico have still not been completely studied, and there are few publications available on this subject. This book provides a state-of-the-art view on Mexican soils, their geographical distribution, their use and degradation. This is a first attempt to give a systematized characteristic of the soil resources of Mexico. Land resources of the second-biggest economy in Latin America are critical for its sustainable development, and a demand for adequate soil information is high. The information contained within can be used for any soil-related research done in Mexico and in neighboring countries. The book includes detailed characteristics of soils of all the physiographic regions of Mexico with maps, photos and explanatory schemes. The book is based on the experiences of the authors in research and soil survey, as well as on the existent, mainly ‘grey’ literature on Mexican soils. The book is recommended for researchers and university readers, students of all levels and decision-makers, working in the area of soil science, environmental issues, Earth sciences, land management and nature conservation.

Available in PDF, EPUB and Kindle. Book excerpt: Pursuing a multidisciplinary approach, this book highlights current challenges in, and potential solutions to, environmental water management in Mexico. It includes an essential review of current literature and state of the art research, providing a one-stop resource for researchers, graduate students and environmental water managers alike. The result of a cooperation between 35 researchers from seven Mexican academic institutions, two Federal Commissions and one international organization, the book links science to practice for living organisms and their environment, while also addressing anthropogenic effects on our water ecosystems. Particularly the book addresses the following subjects: Biodiversity in inland waters, physical and chemical characterization of inland waters, physico-chemical characterization of Mexican coastal lagoons, microbiota in brackish ecosystems, diversity associated with southern Mexico’s pacific coral reefs, fry fish stockings in aquatic epicontinental systems, a review of tuna fisheries in Mexico, fishery resource management challenges stemming from climate change, aquatic invasive alien species, harmful algal blooms, and aquatic protected areas, related ecological and social problems and the importance for fisheries’ yield.

Available in PDF, EPUB and Kindle. Book excerpt: This two-volume handbook is a comprehensive account of the rapidly emerging and vibrant science of the ecological restoration of habitats and species. Ecological restoration aims to achieve complete structural, functional, self-maintaining biological integrity following disturbance. In practice, any theoretical model is modified by a number of economic, social, and ecological constraints. Consequently, material that might be considered as rehabilitation, enhancement, re-construction, or re-creation is also included. Principles of Restoration defines the underlying principles of restoration ecology in relation to manipulations and management of the biological, geophysical, and chemical framework.

This book was released on 2002 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume comprises aspects of both basic and applied limnology. They include works on physical, chemical, and biological limnology, as well as experimental approaches in selected areas. Contributions from investigators regarding aquatic conservation and biodiversity were specifically not available and therefore, these aspects are considered in various included works. Most manuscripts deal with lentic aquatic resources. This is not surprising since Mexican limnology followed the general study trend of that from temperate limnology. Despite this, we must emphasize that lotic resources in Mexico are quite important both locally and regionally. This does not mean that rivers are not under limnological research in Mexico, just that their study has only recently begun. It is the intention of the volume to stimulate a larger section of limnologists to further research in this field. It is to be hoped that policy-framing governmental authorities in Mexico will benefit from it, and consider some of the aspects described so that further damage to the epicontinental waterbodies can be halted, and remedial measures can be considered in the future.

Available in PDF, EPUB and Kindle. Book excerpt: The first-ever book on this subject establishes a rigid, transparent and useful methodology for investigating the material metabolism of anthropogenic systems. Using Material Flow Analysis (MFA), the main sources, flows, stocks, and emissions of man-made and natural materials can be determined. By demonstrating the application of MFA, this book reveals how resources can be conserved and the environment protected within complex systems. The fourteen case studies presented exemplify the potential for MFA to contribute to sustainable materials management. Exercises throughout the book deepen comprehension and expertise. The authors have had success in applying MFA to various fields, and now promote the use of MFA so that future engineers and planners have a common method for solving resource-oriented problems.

Book excerpt: Mexico is among the richest countries in the world in terms of the number of native animal and plant species. Found in a wide variety of habitats--from alpine meadows and tropical forests to vast stretches of desert and isolated pockets of biogeographical uniqueness--these species comprise a fascinating, important, and vastly underutilized biological laboratory. This volume presents a collection of selected papers that explore this marvelous biological abundance. The book is divided into six parts. The first section sets the stage with geological and paleobotanical overviews; the succeeding five sections employ a strong taxonomic base to document species richness, endemism and distribution for animals and plants, followed by reviews of contrasting ecosystems and plants that are closely associated with humans. The last section summarizes the disheartening rate of habitat destruction which threatens to diminish this diversity. In addition to the purely scientific value of this important work, it provides the much-needed basic data that will help conservation policymakers assess and respond to Mexico's ecological evolution.
