Conventional wisdom considers deserts stark, harsh regions that support few living things. Most people also believe that water alone makes the desert bloom. Ecology of Desert Systems challenges these conventional views. This volume explores a broad range of topics of interest to ecosystem, population, community, and physiological ecologists. Climate, weather patterns, geomorphology, and wind and water processes are examined as variables that affect the distribution of biota through fundamental ecosystem processes. Descriptions of morphological, behavioral, and physiological adaptations of desert biota illuminate, through the lens of patch dynamics, principles for understanding observed patterns of primary production, nutrient cycling, and the effects of consumers. Desertification, and the techniques for monitoring and quantifying it, is examined within the framework of desert ecosystem patterns and processes. * Focuses on the interactions of climate, soil, and biota along a spectrum of spatial and temporal scales * Details the role of animals in desert ecosystems and landscape processes * Examines watershed scale processes, the ecology of ephemeral lakes, and the ecological changes identified with desertification * Outlines the fundamental concepts relevant to sustainable development of arid lands

Water is a vital resource for life. Environmental lawyer Stephen C. McCaffery identifies "two ominous phenomena relating to fresh water: increased water usage and increased global population numbers." This combined increase in population and water scarcity has been labeled as a potential cause for future conflicts and wars. No place on earth is this clash more apparent than the Middle East North Africa Region, especially in the state of Egypt. Given the large population in Egypt and the lack of water, this thesis, using the lens of political ecology, explores how historic and contemporary water policies and laws have influenced water quantity and access to water, and, evaluates whether contemporary agricultural policies will aggravate or improve water management in Egypt in relation to water quantity and accessibility. Scarcity, corruption, and ineffective laws and policies have had a negative effect on water quantity and accessibility, ultimately undermining the sustainability of Egypt's use of a scarce natural resource, the River Nile.

The Jornada Basin LTER is located in the Chihuahuan Desert, the largest in North America. This region of south central New Mexico has a history of nearly 100 years as the basis for scientific research. This work gives a thorough, encompassing review of the tremendous array of observations resulting from experiments conducted in this ecosystem. Beginning with thorough descriptions of the most salient features of the region, the book then reviews a wide range of archived and active data sets on a diversity of biotic and abiotic features. It next presents a syntheses of important topics including livestock grazing and remediation efforts. A concluding chapter provides a synthesis of the principles that have emerged from this body of work, and how these relate to the broader fields of ecology and natural resource management. It concludes with recommendations for future research directions. The insightful views expressed in this volume should guide management of arid landscapes globally. This is the sixth volume in the Long Term Ecological Network Series.

The Mojave Desert is a winter-rainfall desert, experiencing drought in the summer months and occasional rain during the cooler winter months. For many years it has attracted the attention of ecologists and conservation biologists concerned with maintaining the unique status of this region. This book provides a broad overview of plant and animal ecology in the Mojave Desert, with a focus on data from Rock Valley, Nevada. The data from many major research projects is organized into a synthesis describing community structure and dynamics in desert ecosystems.

The Desert Experience in Israel shares the responses of settlers, artists, poets, scientists, and educators who lived near the Blaustein Institute in the Negev Desert of Israel as they answer the question, "What difference has living in the desert year round made in your work?" The book begins with a reprint of David Ben-Gurion's call for settlement and science in the desert. This is followed by an account of life in early kibbutzim, a discussion of the meaning of the term "desert," accounts of religion in the desert, and the relationship of the desert experience to art, theatre, literature, poetry, sculpture, and the use of color categories by the Bedouin. Accounts of research on solar energy, fossil fuel, water, microalgae, runoff agriculture, fish, and architecture are followed by desert-related activities in the high school, field school, and research institute.

This book offers a concise but comprehensive introduction to desert ecology and adopts a strong evolutionary focus. As with other titles in the Biology of Habitats Series, the emphasis in the book is on the organisms that dominate this harsh environment, although theoretical and experimental aspects are also discussed. In this updated second edition, there is a greater focus on the effects of climate change and some of its likely effects on deserts, seeing desertification as among the most serious results of climate change, leading ultimately to the increasing size of arid and semi-arid regions. The Biology of Deserts Second Edition includes a wide range of ecological and evolutionary issues including morphological and physiological adaptations of desert plants and animals, species interactions, the importance of predation and parasitism, food webs, biodiversity, and conservation. It features a balance of plant and animal (both invertebrate and vertebrate) examples, and also emphasizes topical applied issues such as desertification and invasive species. The book concludes by considering the positive aspects of desert conservation. This accessible textbook is intended for senior undergraduate and graduate students, as well as professional ecologists, conservation practitioners, and resource managers working in the field of desert ecology.

Ecological research and protection practice develop so fast and achieve a lot at the national agenda.This book is a synthesis of five most exciting and dominant themes in contemporary ecological research in China: biodiversity, ecosystem management, degraded ecosystem restoration, global change and sustainable development.This book spans all the Earth's major ecosystems, such as forests, oceans, grasslands, wetlands, lakes, rivers, farmland and cities.This book provides a platform for scientific research across a variety of disciplines. It will be invaluable to experts, policymakers and local officers and will also be a highly useful resource for undergraduate and postgraduate students.This book will allow researchers, students and policymakers outside China to learn about the significant achievements and applications of ecological research within China.
India is a vast country, and its demographic diversity is striking. This is because of the dynamics of population components within and across states and regions. Populations (caste, communities and tribes) are influenced by the physical environment and by various biological, social, cultural and economic factors. Demographic indicators provide valuable information that forms the basis to assess the status of different states with respect to demographic transition. Keeping this in view, present study was conducted to investigate the population characteristics of Bhils of Barmer, a desert district of Rajasthan along with prevailing health seeking behavior. It has been found that Bhils are clearly lagging behind Indian National Population. Lack of empowerment to women, illiteracy, poor life style and financial status and lack of competitive economy has further added to their miseries. Lack of sturdy roads and transport facilities are indirectly affecting their overall growth. Never the less, a comparison with past studies on tribal health indicates that they are slowly but steadily progressing for a better future.
