Biogeography is the study of the distribution of plant and animal species on Earth over a period of time. It has two branches, which are phytogeography and zoogeography. This field contributes essential knowledge about the composition of various ecosystems as well as the evolutionary processes and migratory patterns occurring within species over time. Habitat adaptation is an important phenomenon that all living organisms exhibit. Conservation and protection of vulnerable regions is vital for the survival of the various species found on our planet. This book is meant for students who are looking for an elaborate reference text on biogeography. For all readers who are interested in this subject, the case studies included in this book will serve as an excellent guide to develop a comprehensive understanding.
