The objective of the book "Introduction to Ecology" is to provide readers with a comprehensive understanding of the fundamental concepts and principles of ecology. Through clear and concise explanations, this book aims to introduce readers to the intricate relationships between organisms and their environment. It explores various ecological concepts such as population dynamics, community interactions, and ecosystem functioning. The book also emphasizes the importance of ecological research in addressing environmental challenges and promoting sustainability. By the end of this book, readers will have a solid foundation in ecological principles, enabling them to appreciate the intricate web of life and make informed decisions for a more harmonious coexistence with nature.

Professor Vinay Kumar Singh, Ph. D., Department of Zoology, DDU Gorakhpur University, born on 15th July, 1969, has a brilliant academic carrier. Prof Singh has involved himself in research on Fasciolosis and its snail vectors control since 1993. Current research interests are Isolation, characterization and biological evaluation of Natural Plant Products and pest control, Vector-Borne Diseases, Toxicology & Pharmacology. Prof Singh has University teaching and research experiences of more than 30 years. Prof Singh has successfully isolated and identified pure molluscicidal compounds from more than a dozen medicinal plants and observed their mode of action on the snails at cellular level. His work is recognized internationally in the field of formulation and use of synthetic and bio-pesticides for integrated pest/ vector-diseases management. Prof Singh has devised a bioassay method for pesticides using isolated organs of snails. Currently, he is working on the pesticidal property of the different formulations of cow urine of Indian cow breeds singly or synergistically with bioactive product of plant molluscicides. The research publication on fasciolosis control by means of characterized plant derived pesticides, synergistic combinations, bait formulations or by reducing the reproductive capacity of vector/host to limit the population below threshold level which are widely quoted and acclaimed world over. Prof Singh has published 154 research papers in 94 leading International Journals of repute.
