Book excerpt: El cambio global afectará de forma importante a la biodiversidad y a los servicios ecosistémicos. El empleo de atributos funcionales de los ecosistemas a escala regional en la evaluación de las consecuencias de estos cambios se muestra ventajoso a la hora de conectar los estudios locales y globales y de cara a establecer programas de seguimiento. Sin embargo, no son muchos los trabajos a escala regional que analizan los efectos del cambio global sobre el funcionamiento de los ecosistemas de la Península Ibérica o que proporcionen una situación de referencia frente a la que comparar el efecto del uso de la tierra y de los cambios climáticos y atmosféricos sobre los ecosistemas. En esta Tesis se documentaron los patrones espaciotemporales de la fracción de radiación fotosintéticamente activa (fPAR) interceptada por parte de la vegetación actual de la Península Ibérica, así como las tendencias observadas en la misma para los ecosistemas protegidos bajo la Red Española de Parques Nacionales. También, se exploraron los controles climáticos y de usos del suelo que subyacen detrás de los patrones encontrados. Para ello, se empleó como medida integradora del funcionamiento ecosistémico un estimador del fPAR y, por tanto, de la productividad primaria neta: el Índice Verde Normalizado (NDVI) obtenido a partir de imágenes NOAA/AVHRR entre 1982 y 1999. Se utilizaron los siguientes atributos funcionales de las curvas estacionales de este índice: la integral anual, la variabilidad intraanual o rango relativo, los valores máximo y mínimo de NDVI, la época en la que se alcanzan estos valores, y las variabilidades interanuales de todos ellos. Se identificaron Tipos Funcionales de Ecosistemas que recogieron de forma sintética la heterogeneidad espacial del fPAR en la Península y cuyos patrones sugieren que el uso de la tierra modifica a escala regional los ciclos del carbono. La precipitación, la temperatura, la vegetación potencial y el tipo de uso por el cual se la reemplaza, controlaron la magnitud y el sentido de las diferencias en la dinámica del NDVI. La caracterización de atributos funcionales en áreas naturales, seminaturales y protegidas de España reveló los diferentes controles que determinan la dinámica del NDVI a lo largo de los gradientes ambientales entre la Región Mediterránea y la Eurosiberiana. El análisis sobre parques nacionales mostró algunos huecos en la Red y permitió diferenciar aquellos parques que representan tipos de funcionamiento ecosistémico singulares en el contexto ibérico, de aquellos otros que constituyen paisajes representativos del funcionamiento de gran parte de la vegetación ibérica. Además, nuestros resultados pusieron de manifiesto cómo los parques nacionales españoles, áreas con altos niveles de protección, tendieron a aumentar la productividad y a disminuir las diferencias entre las estaciones de crecimiento y de reposo en el corto plazo. En conjunto, esta Tesis ofrece una caracterización de referencia frente a la que evaluar los efectos del cambio global sobre el funcionamiento de los ecosistemas ibéricos y con la que incorporar aspectos funcionales de los ecosistemas a las políticas de conservación de la naturaleza y de mantenimiento de los servicios ecosistémicos, en concreto, los relacionados con el secuestro de carbono.

Available in PDF, EPUB and Kindle. Book excerpt: Mexican conservationists have sometimes observed that it is difficult to find a country less interested in the conservation of its natural resources than is Mexico. Yet, despite a long history dedicated to the pursuit of development regardless of its environmental consequences, Mexico has an equally long, though much less developed and appreciated, tradition of environmental conservation. Lane Simonian here offers the first panoramic history of conservation in Mexico from pre-contact times to the current Mexican environmental movement. He explores the origins of conservation and environmental concerns in Mexico, the philosophies and endeavors of Mexican conservationists, and the enactment of important conservation laws and programs. This heretofore untold story, drawn from interviews with leading Mexican conservationists as well as archival research, will be important reading throughout the international community of activists, researchers, and concerned citizens interested in the intertwined issues of conservation and development.

Available in PDF, EPUB and Kindle. Book excerpt: This book is number two in a series for Primates in Fragments. In this volume, ten years after the first http://www.springer.com/social+sciences/anthropology+%26+archaeology/book/978-0-306-47696-9, we continue to address issues regarding primates within a fractured landscape. There are seven sections based on specific categories of primates in fragments. In the Introductory section, authors discuss the issues surrounding primates in remnant habitats as well as encourage discussion about what we mean by fragmentation on a landscape scale. In the Long-Term and Regional Studies section, authors present information on changes that have occurred during longer studies as well as changes that have occurred over regions. In the Landscape, Metapopulations and the Matrix section, authors cover topics from dry to moist forests, and from metapopulations to single species use of multiple fragments locations. In Feeding and Behavioral Ecology, authors take a closer look at the flexibility and responsiveness of primates in fragments in terms of their food choices, resource use, and behavioral changes. In Endemic, Endangered, and Nocturnal Primates authors uncover details involving critical primates living in major city centers to the heights of the Himalayas. In Genetics, Disease and Parasites authors cover topics including population viability, disease and parasite transmission between primates in fragments and humans. Finally, in the Conservation and Ecology: Threats and Management section, we synthesize information in this volume and make recommendations for the future of work in this field and the survivability of primates in fragments.

Available in PDF, EPUB and Kindle. Book excerpt: This volume was created initially from a symposium of the same name presented at the International Primatological Society's XVIII Congress in Adelaide. South Australia. 6-12 January 2000. Many of the authors who have contributed to this text could not attend the symposium. so this has become another vehicle for the rapidly growing discipline of Fragmentation Science among primatologists. Fragmentation has quickly become a field separate from general ecology. which underscores the severity of the situation since we as a planet are rapidly losing habitat of all types to human disturbance. Getting ecologists. particularly primatologists. to admit that they study in fragments is not easy. In the field of primatology. one studies many things. but rarely do those things (genetics. behavior. population dynamics) get called out as studies in fragmentation. For some reason "fragmentation primatologists" fear that our work is somehow "not as good" as those who study in continuous habitat. We worry that perhaps our subjects are not demonstrating as robust behaviors as they "should" given fragmented or disturbed habitat conditions. I had a colleague openly state that she did not work in fragmented forests. that she merely studied behavior when it was clear that her study sites. everyone of them. was isolated habitat. Our desire to be just another link in the data chain for wild primates is so strong that it makes us deny what kinds of habitats we are working in. However.

This book was released on 1986-08-21 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: The survival of primates in their natural habitats is of growing concern to primatologists, ecologists and conservationists. In this volume, research on feeding behaviour, nutrition and digestive physiology from captive and wild primates is presented. Correlates of the habitat and social organisation are discussed, and then integrated with the pressing problem of how to conserve primates. Broad issues of confrontation between human and non-human primate populations are considered in the light of conflicting priorities for land-use and development. The increased knowledge of what primates require for their survival is applied to problems of captive propagation as a means of reducing dependence on exploiting wild populations. The papers presented in this volume will stimulate discussion between ecologists, conservationists and those concerned with land-use management to establish realistic policies for primate conservation.

Download or read book Water Quality Hydrology written by V.P. Singh and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is vital to life, maintenance of ecological balance, economic development, and sustenance of civilization. Planning and management of water resources and its optimal use are a matter of urgency for most countries of the world, and even more so for India with a huge population. Growing population and expanding economic activities exert increasing demands on water for varied needs--domestic, industrial, agricultural, power generation, navigation, recreation, etc. In India, agriculture is the highest user of water. The past three decades have witnessed numerous advances as well as have presented intriguing challenges and exciting opportunities in hydrology and water resources. Compounding them has been the growing environmental consciousness. Nowhere are these challenges more apparent than in India. As we approach the twenty first century, it is entirely fitting to take stock of what has been accomplished and what remains to be accomplished, and what accomplishments are relevant, with particular reference to Indian conditions.
Download or read book Landscape Evolution written by Jonathan D. Phillips and published by Elsevier. This book was released on 2021-04-30 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landscape Evolution: Landforms, Ecosystems and Soils asks us to think holistically, to look for the interactions between the Earth's component surface systems, to consider how universal laws and historical and geographical contingency work together, and to ponder the implications of nonlinear dynamics in landscapes, ecosystems, and soils. Development, evolution, landforms, topography, soils, ecosystems, and hydrological systems are inextricably intertwined. While empirical studies increasingly incorporate these interactions, theories and conceptual frameworks addressing landforms, soils, and ecosystems are pursued largely independently. This is partly due to different academic disciplines, traditions, and lexicons involved, and partly due to the disparate time scales sometimes encountered. Landscape Evolution explicitly synthesizes and integrates these theories and threads of inquiry, arguing that all are guided by a general principle of efficiency selection. A key theme is that evolutionary trends are probabilistic, emergent outcomes of efficiency selection rather than purported goal functions. This interdisciplinary reference will be useful for academic and research scientists across the Earth sciences. - Serves as a primary theoretical resource on landscape evolution, Earth surface system development, and environmental responses to climate and land use change - Incorporates key ideas on geomorphic, soil, hydrologic, and ecosystem evolution and responses in a single book - Includes case studies to provide real-world examples of evolving landscapes
