A galactic literature could be found on the captivating topic plant ecology, but the apprenti‐ ces on this wide topic could never be conclusive. This book is aimed to cover the phyloge‐ netic and functional ecology with special reference to ecological shifts. I hope this book may benefit the students, fellow professors, and resource managers studying plant sciences. Since the topics stated in this book are not new but the issues and technologies mentioned were new to me, I expect that they will be new and equally advanced for the readers too.

While editing this book, I kept few key assumptions relevant to the experience of my audi‐ ence and available information about life sciences. Hence, I deliberately wrote for the audi‐ ences who are already well familiarized with plants and ecology. The key element included into the text of this book covers:


I encourage the readers to get out into the field to identify plants and to dig out the anthro‐ pogenic and social activities effecting plants to come along with the development of plant ecology; to rise and serve the topic of the enormous number of plants facing extinction; and to relish themselves and make some effort to contribute something to the world.

I want to thank InTech Publishers for providing me such ravishing platform to work with the young and emerging scientists. It has been a great experience working with them and interacting with international scientists. Also, I would also want to thank the Lahore College for Women University for cherishing and encouraging its employers and students to cater their contributions in the field of life sciences.
