I wish to express sincere gratitude to my hardworking, responsive and praiseworthy supervisor Dr. Muhammad Mahmood-ul-Hassan, Chairman and Associate Professor, Department of Wildlife and Ecology, University of Veterinary and Animal Sciences, Lahore for his affectionate supervision, demonstrative guidance, sympathetic behavior and tremendous help not only in accomplishment of present study but also in every aspect of my life. I am also grateful to the members of my supervisory committee, Prof. Dr. Mirza Azhar Beg, Eminent Educationist, Department of Zoology, University of Arid Agriculture, Rawalpindi, Dr. Muhammad Ali Nawaz, Assistant Professor, Department of Wildlife and Ecology and Prof. Dr. Muhammad Akram, Chairman, Department of Poultry Production, University of Veterinary and Animal Sciences, Lahore for their skillful guidance and critical insight. Special thanks are extended to all my friends especially members of the PhD club and colleagues for their wishes and cordial cooperation during the studies. Lastly, I wish to thank my family especially my father, mother, my brothers and sisters who always pray for my success. They taught, loved and supported me to achieve higher goals in life. Their concern in me can never be fully returned but will always be remembered. This pioneering study on bats in Pakistan would have not been possible without the financial assistance of the Higher Education Commission of Pakistan (HEC Project/20-1033/R&D) and the Rufford Small Grants Commission UK (RSG 12.4.09). the monetary support provided by both these funding agencies is gratefully acknowledged.
