Description
Environnemental Biologie is an important component de le Environnemental Science et is concerned avec le study de air, land, water et energy system en relation to le life. Le framework de le book is based upon le UGC syllabi. Le Book is primarily designed to meet le requirement de both undergraduates et postgraduates courses en Indien Universities. Presently, le Environnemental Biologie has become an important component de le syllabi de several disciplines including Science, Social Sciences commerce, Gestion et Ingénierie etc. As such, le book will be useful to le students et teachers de all these disciplines. It would also cater le needs de students undertaking competitive examinations. Le authors have tried to present a simple, comprehensible, illustrated et authentic account de le Environnement, Aquatic ecology, wildlife conservation et natural resources et their conservation. Thus, this book covers all aspects de le subjects Environnemental Biologie. Le Book would prove friendly to all students et teachers de le Environnemental Biologie. Beside, eighteen chapters dealing avec de general aspects de Environnemental Biologie, this book contains some specific chapters sur modern branches including those sur Urbanization, Biodiversity, Environnemental Biotechnologie, Biopiracy et Eco- terrorism make this book special than others. With these general et specific portions, this book is bound to fulfill le hopes de every student et teacher de le Environnemental Biologie. Le others characteristic de le book is its language. It is very simple et easy to understand. As per le requirement de le topics, figures et tables have also been added. At le end de every chapter, relevant questions have also been given which will help le students to assess their preparations. We hope, this book would prove useful to everyone who read it. Special features de le book are as under : User friendly et easy to understand. Text presented en simple et lucid language, et Table et figures are given at appropriate places pour le better understanding.
