Hardbound. Condición: As New. New. Contents Preface. 1. Introduction i. Ecology. ii. Insects. 2. Classification of insects. 3. Origin of insects. 4. Insects one of the most successful group. 5. Aquatic insects i. Fresh water habitat. ii. Marine water habitat. iii. Orders of aquatic insects. iv. Adaptation in aquatic insects. v. Life cycle in aquatic insects. vi. Filter feeding in aquatic insects. This is the happiest moment for the authors to present Ecology of Aquatic Insects to readers of this discipline. Study of any organism without considering its ecology is not complete as no organism can be separated from its environment. About 75% of earth's surface is covered by water which is source of life on earth. It is the medium within which all aspects of ecosystem co exist both living and non living. Insects have adopted themselves to occupy almost every conceivable ecological niche in on or above the earth. They are all around us occupying our houses puncturing our skin consuming our food and clothing. There is scarcely any place on the earth that is not home to atleast one kind of insects. They endure all extremes of environment and are the most successful group of animals from Protozoa to mammals. This is an attempt to provide distinct advantage to its user (undergraduate postgraduate and life science students and also the researchers who are engaged in deciphering the mystery of aquatic ecology) towards better understanding of relation between insects and aquatic environment. 240 pp. …

From the Preface Aim of this book is to bridge the gap between traditional materials on pollution and quantitative and technical aspects that are the essence of most advanced environmental science. The book will also provide necessary informations on environmental chemistry and physics that are prerequisite for the mechanism of working of pollutants. Various chapters of the book covering water pollution air pollution soil pollution noise pollution and radiation describe in details about the sources and effects of pollutants. Control measures to mitigate pollution are added at the end of each chapters. Special emphasis has been laid on topics of international and global concern such as greenhouse effect stratospheric ozone depletion photochemical smog aerosols and acid rains and are discussed well. This book will satisfy the needs of undergraduate and postgraduate students of environmental biology. This book has been checked thoroughly and corrected to the best of our knowledge however errors and suggestions brought to our notice will be appreciated. 222 pp.…
