This book is divided into four parts. The first part, Preliminaries, begins by introducing the basic theme of the book. It provides an overview of the current status of water resources utilization, the likely scenario of future demands, and advantages and disadvantages of systems techniques. An understanding of how the hydrological data are measured and processed is important before undertaking any analysis. The discussion is extended to emerging techniques, such as Remote Sensing, GIS, Artificial Neural Networks, and Expert Systems. The statistical tools for data analysis including commonly...

An increasing variety of biological problems involving resource management, conservation and environmental quality have been dealt with using the principles of population biology (defined to include population dynamics, genetics and certain aspects of community ecology). There appears to be a mixed record of successes and failures and almost no critical synthesis or reviews that have attempted to discuss the reasons and ways in which population biology, with its remarkable theoretical as well as experimental advances, could find more useful application in agriculture, forestry, fishery,...

Presenting current developments and trends in ring theory, this text highlights newer techniques as well as those that are more established.

This work aims to define and reassess the role of population genetics in conservation biology and seeks to identify the progress made in the field during the last decade. It deals with conservation genetics from several currently researched points of view, such as: ecological and demographic measures of rarity or population persistence; loss of genetic variation; inbreeding; reduced migration rates and increased selective pressures under stress; and the role of social behaviour and metapopulation structure. The use of molecular variation as the basis of naming or selecting target taxa and...
