Book Description
This book synthesizes existing information on the ecology, diversity, human uses, and research needs of the Middle Rio Grande Basin of New Mexico. Divided into nine chapters, the volume begins with reviews of the environmental history and human cultures in the Basin, followed by an analysis of the influences and problems of climate and water. Later chapters focus on ecological processes, environmental changes, management problems, and current conditions in Basin ecosystems identified as being especially susceptible to damage: pinyon-juniper woodlands, grasslands and shrublands, and the riparian bosque of the Rio Grande. Research needs associated with land management problems are identified for each of these ecosystem types. Many interrelated factors, identified here, have contributed to deteriorating environmental conditions in the Basin. Concluding chapters on the belowground ecology of specific Basin ecosystems and on declining populations of native fish species highlight topics in need of further attention. Each chapter seeks to identify studies that can supply information to mitigate environmental problems, rehabilitate ecosystems, and sustain them in light of human values and needs.

Impact of Agricultural Practices on Biodiversity of Soil Invertebrates
Author: Stefano Bocchi
Publisher: MDPI
ISBN: 3039437194
Category : Science
Languages : en
Pages : 150
Book Description
Soil fauna plays a key role in many soil functions, such as organic matter decomposition, humus formation, and nutrient release, modifying soil structure, and improving its fertility. Soil invertebrates play key roles in determining soil suitability for agricultural production and realizing sustainable farming systems. They include an enormous diversity of arthropods, nematodes, and earthworms. However, this fauna suffers from the impact of agricultural activities with implications for the capacity of soil to maintain its fertility and provide ecosystem services. Some agricultural practices may create crucial soil habitat changes, with consequences for invertebrate biodiversity. In the few last decades, especially under intensive and specialized farming systems, a loss in soil ecosystem services has been observed, as a result of the reduction in both the abundance and taxonomic diversity of soil faunal communities. On the other hand, agricultural practices, based on sustainable soil management, can promote useful soil fauna. Therefore, the concerns about the sensibility of soil biota to the agricultural practices make it urgent to develop sustainable management strategies, able to realize favorable microclimate and habitats, and reduce the soil disturbance.

Arthropod Diversity and Conservation in the Tropics and Sub-tropics
Author: Akshay Kumar Chakravarthy
Publisher: Springer
ISBN: 981101518X
Category : Science
Languages : en
Pages : 443
Book Description
Arthropods are invertebrates that constitute over 90% of the animal kingdom, and their bio-ecology is closely linked with global functioning and survival. Arthropods play an important role in maintaining the health of ecosystems, provide livelihoods and nutrition to human communities, and are important indicators of environmental change. Yet the population trends of several arthropods species show them to be in decline. Arthropods constitute a dominant group with 1.2 million species influencing earth’s biodiversity. Among arthropods, insects are predominant, with ca. 1 million species and having evolved some 350 million years ago. Arthropods are closely associated with living and non-living entities alike, making the ecosystem services they provide crucially important. In order to be effective, plans for the conservation of arthropods and ecosystems should include a mixture of strategies like protecting key habitats and genomic studies to formulate relevant policies for in situ and ex situ conservation. This two-volume book focuses on capturing the essentials of arthropod inventories, biology, and conservation.Further, it seeks to identify the mechanisms by which arthropod populations can be sustained in terrestrial and aquatic ecosystems, and by means of which certain problematic species be managed without producing harmful environmental side-effects. This edited compilation includes chapters contributed by over 80 biologists on a wide range of topics embracing the diversity, distribution, utility and conservation of arthropods and select groups of insect taxa. More importantly, it describes in detail the mechanisms of sustaining arthropod ecosystems, services and populations. It addresses the contribution of modern biological tools such as molecular and genetic techniques regulating gene expression, as well as conventional, indigenous practices in arthropod conservation. The contributors reiterate the importance of documenting and understanding the biology of arthropods from a holistic perspective before addressing conservation issues at large. This book offers a valuable resource for all zoologists, entomologists, ecologists, conservation biologists, policy makers, teachers and students interested in the conservation of biological resources.

Toward Sustainable Agricultural Systems in the 21st Century
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309148960
Category : Technology & Engineering
Languages : en
Pages : 598
Book Description
In the last 20 years, there has been a remarkable emergence of innovations and technological advances that are generating promising changes and opportunities for sustainable agriculture, yet at the same time the agricultural sector worldwide faces numerous daunting challenges. Not only is the agricultural sector expected to produce adequate food, fiber, and feed, and contribute to biofuels to meet the needs of a rising global population, it is expected to do so under increasingly scarce natural resources and climate change. Growing awareness of the unintended impacts associated with some agricultural production practices has led to heightened societal expectations for improved environmental, community, labor, and animal welfare standards in agriculture. Toward Sustainable Agricultural Systems in the 21st Century assesses the scientific evidence for the strengths and weaknesses of different production, marketing, and policy approaches for improving and reducing the costs and unintended consequences of agricultural production. It discusses the principles underlying farming systems and practices that could improve the sustainability. It also explores how those lessons learned could be applied to agriculture in different regional and international settings, with an emphasis on sub-Saharan Africa. By focusing on a systems approach to improving the sustainability of U.S. agriculture, this book can have a profound impact on the development and implementation of sustainable farming systems. Toward Sustainable Agricultural Systems in the 21st Century serves as a valuable resource for policy makers, farmers, experts in food production and agribusiness, and federal regulatory agencies.

Urban Ecology
Author: John Marzluff
Publisher: Springer Science & Business Media
ISBN: 0387734120
Category : Science
Languages : en
Pages : 802
Book Description
Urban Ecology is a rapidly growing field of academic and practical significance. Urban ecologists have published several conference proceedings and regularly contribute to the ecological, architectural, planning, and geography literature. However, important papers in the field that set the foundation for the discipline and illustrate modern approaches from a variety of perspectives and regions of the world have not been collected in a single, accessible book. Foundations of Urban Ecology does this by reprinting important European and American publications, filling gaps in the published literature with a few, targeted original works, and translating key works originally published in German. This edited volume will provide students and professionals with a rich background in all facets of urban ecology. The editors emphasize the drivers, patterns, processes and effects of human settlement. The papers they synthesize provide readers with a broad understanding of the local and global aspects of settlement through traditional natural and social science lenses. This interdisciplinary vision gives the reader a comprehensive view of the urban ecosystem by introducing drivers, patterns, processes and effects of human settlements and the relationships between humans and other animals, plants, ecosystem processes, and abiotic conditions. The reader learns how human institutions, health, and preferences influence, and are influenced by, the others members of their shared urban ecosystem.
