Available in PDF, EPUB and Kindle. Book excerpt: Management and Analysis of Biological Populations demonstrates the usefulness of optimal control theory in the management of biological populations and the Liapunov function in simulating an ecosystem model under large perturbations of its initial state and continual disturbances on its dynamics. The first chapter of the book introduces the topic by presenting the different models in ecology and discussing the stability concepts, the ecological engineering, and various relevant functions in ecosystem modeling. The next chapter contains a brief survey of static optimization techniques and optimal control theory for systems, which are modeled by differential and difference equations. Another chapter covers methods that use Liapunov and Liapunov-like functions to establish that a given population model is stable relative to finite perturbations of its initial state and that it is non-vulnerable relative to large continual disturbances. The book also covers fisheries and logistic modeling, including a discussion of a few management problems. Moreover, this reference considers stability in an ecosystem model with complexities due to species richness, nonlinearities, time delays, and spatial heterogeneity. Finally, it explains how to manage pests and greenhouse crops. The book is an excellent reference source for students and professionals in ecology and environmental engineering. Research professionals and extended workers in agriculture and agronomy will also find this book invaluable.

Download or read book Shrub-Steppe written by Alec Rickard and published by Elsevier. This book was released on 2012-12-02 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Owing to man-made intervention, the shrub-steppe now represents a rapidly disappearing landscape in the arid regions of North America. This book represents a systems-level study of ecological variables affecting water balance, and responses to perturbation. The study focused on a very large, protected, landscape unit, comprising a natural ``watershed'' area located in the semi-arid western United States. Long-term and concurrent data sets were established with a view towards establishing system-level responses to manipulative interventions, and natural perturbations like wildfire. These data sets were established for micrometeorology, climatology, mineral cycling in soils, nutrient and mineral pathways in springs and streams, vegetational dynamics, and population changes on the site. In synthesizing nearly twenty years of data, the more interesting ecosystem level responses concerned vegetational recovery and water balance. For instance, the synthesis uniquely demonstrates the interaction of biotic and non-biotic factors and their integrated effect on regional water balance. However, special attention was also paid to species diversity and the genetic resource pool represented at this site.This book will be of primary interest as a reference resource to land managers and wildlife specialists, and as a research study for scientists interested in systems-level ecology. Conservation-minded citizens who take more than a cursory interest in ecology will also find it interesting.
Book Synopsis Before Water Management Measures by :
Download or read book Before Water Management Measures written by and published by Elsevier. This book was released on 2012-12-02 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ultimate motivation for the study which is the subject of this book was the need to draw conclusions on the impact of man's activity on natural ecosystems. The results characterize the situation of the south-Moravian floodplain forest in the period of fading uncontrolled floods before the extensive technical measures successively changed the moisture regime by eliminating inundation and lowering the level of underground water. This publication is unique in Czechoslovakia as it records the ecological situation in the floodplain forest prior to the major and irreversible changes. The study also documents the exceptional role played by the Central-European floodplain forest in maintaining the gene pool and structure of the one thousand or so species in flora and fauna of an agricultural region.

Book Synopsis Nitrogen Management and Ground Water Protection by : Ronald F Follett
Download or read book Nitrogen Management and Ground Water Protection written by Ronald F Follett and published by Elsevier. This book was released on 2012-12-02 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supplying crops with adequate nitrogen is vital to ensuring food supplies. Once nitrogen is added to the soil, it is subject to chemical transformations of the nitrogen-cycle including transformation to nitrate. Excessive amounts of accumulated nitrate may then leach out of the soil and could potentially enter and contaminate drinking water supplies. The purpose of this book is to examine the subject of nitrogen management and ground water protection.The issue of maintaining ground water quality is addressed primarily from an agronomic point of view. Topics covered include: health and economic aspects of nitrate in drinking water; nitrate sources; ground water nitrate in the USA and other developed countries; transport, leaching and accounting for nitrogen; soil, nitrogen, crop and water management; and nitrate in aquifer systems. The book contains a keyword index and is organized into thirteen chapters, each with appropriate references, tables and figures. Chapter authors are among the leading experts on the subject of nitrate and ground water quality.Readers to whom the book is directed include soil scientists and agronomists, agricultural engineers (irrigation and drainage), environmental scientists, agricultural policy makers, and hydrologists.
