Zoology is that branch of biology, which treats issues concerning animals. It is a vast and well-established which touched almost every part of animal life. Animals of any spices, particularly, mammals have a close mutual relationship with humans. Rather they serve the mankind in various ways so much so that even the wastes there of pay off well.

Skin of the animals, bones, fur, horns, flesh and other organs- all are of enormous worth to man. Tanning is one of the most thriving industries. Similarly, in medicine, various parts of animals are made use of extensively. Present work is an important document on economy zoology. It offers an insightful and a wide range of information in simple and interesting style and language. A must for every business-enthusiast.

Physiology is that branch of science which pertains to the physique or the bodily structure of any living being. All the functions of living organisms are studied under this head. Plant Physiology, especially deals with plants and their systems. Of the systems, the reproductory system is of the greatest importance as far as the physiology of plants goes. Unlike humans' and like animals, plants have been classified into different groups on the basis of their behaviour.

An interesting subject, Plant Physiology, needs to be studied at length with an eye to unveiling the treasure of benefits for man. This encyclopaedia is a humble effort in the same direction which elaborately discuses all relevant issues in pros and cons.

Biodiversity is regarded as variety of life and its diverse processes. All living forms from bacteria, fungi and protozoa to higher plants, sponges, coelenterates, annelids, arthropods, fishes, birds and mammals are included in biodiversity. Biodiversity also includes millions of species, subspecies, their local variants, ecological processes and cycles linking organisms into populations, communities, ecosystems and biosphere. The present publication is aimed to describe the biodiversity of two lentic ecosystems including Lower lake and Mansaovar lake of Bhopal and three lotic ecosystems including rivers Khan near Indore, River Kshiprra near Ujjain and River Chambal near Nagda in Madhya Pradesh and near Kota in Rajasthan. Physicochemical characteristics of these wetlands have also been attempted to correlate their influence on aquatic organisms. In India biodiversity of forests and higher animals has attracted some attention but limited baseline data is available on lower aquatic organisms such as, phytoplankton, zooplankton, periphyton, benthos and macrophytes.

The text has been described in four chapters. The first chapter deals with general introduction about biodiversity. The second chapter deals with Lentic of Lacustrine environment of the Lower lake and Mansarovar lake of Bhopal. The third chapter deals with the lotic or riverine environment including biodiversity of three rivers viz. Khan near Indore, Kshipra near Ujjain, Chambal near Nagda and Chambal near Kota. The fourth chapter deals with recommendations for further studies. In the end references have been given. Certainly, the present volume will provide baseline information under a single cover for further studies.

Agriculture forms the backbone of the Indian economy and despite concerted industrialisation in the last five decades; agriculture occupies a place of pride. Being the largest industry in the country, agriculture is the source of livelihood for over 70 per cent of population in the country. The significance of agriculture in the national economy can be bet explained by considering the role of agriculture under different heads. The significance of agriculture in India arises also from the fact that the development in agriculture is an essential condition for the development of national economy. However, agriculture dominates the economy to such an extent that a very high proportion of working population in India is engaged in agriculture. Agriculture provides raw materials for a number of industries, e.g. sugar, tea, cotton and jute textiles, hydrogenated oils, food products, soap and some other agro-based industries which together account for 45 per cent of income generated in the manufacturing sector in India.

This work, in two volumes, contains very useful and well-researched material derived from authoritative sources. pros and cons of the theme are discussed in analytical manner. Substantially based on latest data this will prove a dependable reference work. The book will be useful and interesting to students of Indian agriculture, educated farmers, political leaders, and planners in India and abroad.
