This book discusses theoretical approaches to the taxonomy of biological systems and theory and mathematical approaches to the problem of plant diversity, cultivation, and the environment. Particular attention is given to theoretical and practical problems of soil and the environmental sustainability of phytocoenosis, with the goal to enhance the p
Increasing domination of ecosystems by humans is steadily transforming them into depauperate systems. How will this loss of biodiversity affect the functioning and stability of natural and managed ecosystems? This work provides comprehensive coverage of empirical and theoretical research.
With the accelerating loss of biodiversity there is increasing concern about how this loss may be affecting ecosystem processes, or services, that are of benefit to human well being. The limited studies that address the principal question directly, species numbers versus system function, are evaluated. Moreover, the degree of redundancy within systems, the ubiquity of keystone species, the tightness of species interactions from mutualisms to food webs, the resilience of systems to perturbation, the interactions of landscape units are explored, as is also how policy decisions are driven in this research area. This book brings together the disciplines of population biology and ecoysystem science, both directed toward evaluating the consequences of human-driven disruptions of natural systems.
Resource-management decisions, especially in the area of protecting and maintaining biodiversity, are usually incremental, limited in time by the ability to forecast conditions and human needs, and the result of tradeoffs between conservation and other management goals. The individual decisions may not have a major effect but can have a cumulative major effect. Perspectives on Biodiversity reviews current understanding of the value of biodiversity and the methods that are useful in assessing that value in particular circumstances. It recommends and details a list of components-including diversity of species, genetic variability within and among species, distribution of species across the ecosystem, the aesthetic satisfaction derived from diversity, and the duty to preserve and protect biodiversity. The book also recommends that more information about the role of biodiversity in sustaining natural resources be gathered and summarized in ways useful to managers. Acknowledging that decisions about biodiversity are necessarily qualitative and change over time because of the nonmarket nature of so many of the values, the committee recommends periodic reviews of management decisions.
Biodiversity: Structure and Function is a component of Encyclopedia of Environmental and Ecological Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. The Theme on Biodiversity: Structure and Function discusses matters of great relevance to our world such as: Characterization of Biodiversity; Biodiversity and Ecosystem Functioning; Spatial and Temporal Dimensions of Biodiversity Dynamics; Evolutionary and Genetic Aspects of Biodiversity; Biodiversity Monitoring, Assessment, Data Management, and Indicators; The Value of Biodiversity; Halting Biodiversity Loss: Fundamentals and Latest Trends of Conservation Science and Action; Application of Ecological Knowledge to Habitat Restoration. These two volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.
This new volume, Biological Assessment of Natural and Anthropogenic Ecosystems: Trends in Diagnosis of Environmental Stress, diverse methods and achievements in assessing the biological state of ecosystems are presented, biochemical, genetic and cytological methods are used, methodological achievements in this area are discussed in this volume. Experimental and practical aspects of the genetic diversity of cultivated plants and its application in modern business conditions are considered. The use of biological indicators for the purpose of protecting nature and practical application is presented. The authors of the book are biologists, biochemists, genetics, and ecologists from prestigious scientific institutions. This volume explores different types, different plant tissues and intracellular structures for the diagnosis and prediction of anthropogenic effects on living natural systems. Here, scientific information on the bioindication properties of living systems is presented and the theoretical foundations of its study are emphasized. This authoritative reference source will be a valuable addition for scientific researchers and students working in the field of biology, ecology, genetics, cytogenetics, agronomy and environmental assessment and its protection from anthropogenic destruction. The authors highlight the achievements, problems, and opportunities of biological methods for indicating the environment. Key features: Provides an overview of recent events and opportunities in the field of bioindication to control anthropogenic damage of living systems Considers the screening of new parameters to determine the health status of biological objects from one cell to an entire ecosystem, such as boreal peatlands Presents the results of a study of the response of plants to abiotic stressors Demonstrates the importance of role-related research of living objects as bioindicators Provides new research on various topics of plant resistance to stress Discusses design methodology, development and law of selection of indicators for specific environmental issues.
The loss of the earth's biological diversity is widely recognized as a critical environmental problem. That loss is most severe in developing countries, where the conditions of human existence are most difficult. Conserving Biodiversity presents an agenda for research that can provide information to formulate policy and design conservation programs in the Third World. The book includes discussions of research needs in the biological sciences as well as economics and anthropology, areas of critical importance to conservation and sustainable development. Although specifically directed toward development agencies, non-governmental organizations, and decisionmakers in developing nations, this volume should be of interest to all who are involved in the conservation of biological diversity.
This new collection covers a wide variety of research on the ecological aspects of crops growing under stress conditions due to atmospheric changes and pollution and the impact on both plant and human health. The book provides research that will help to find ways to overcome adverse abiotic environmental factors and unfavorable anthropogenic pressu
