Environmental Studies is a vast and rapidly growing subject with increasing relevance for sustainable development. It is the systematic study of environment with our proper place and role in it. Realizing the importance of imparting environmental education the Supreme Court directed that a basic course on environment be introduced as a compulsory subject at all levels of education. Environmental Studies deals with the various facets and dimensions of environment in an integrated multidisciplinary and holistic manner. It provides an up to date introductory view of essential topics in environmental studies to help students understand and retain the general principles. It is written with the understanding that even non science students should be able to use it. At the same time it has enough depth to make it suitable as a textbook for students of different courses. 272 pp. …

"Aquatic fungi contribute to the energy flow and productivity of an aquatic and semi aquatic ecosystems by their active role in the utilization and biodeterioration of organic materials. These fungi also possess the ability to parasitize aquatic plants and animals including fishes under certain conditions. Physiology, environmental needs and activity of these fungi vary with their morphological characters. The taxonomy of these fungi can not remain static. The morphological variability of these species ultimately be linked to the genetic control of their characters. A considerable amount of taxonomic studies has been carried out by a number of mycologists all over the world. The present monograph shows occurrence, distribution, taxonomic characters and keys to the species of different genera belonging to Blastocladiales, Monoblepharidales, Saprolegniales, Leptomitales and Lagenidiales isolated time to time from various ecological conditions of India.
