The branch of biology that studies the interactions between organisms and their environment is known as ecology. Biodiversity, biomass, populations of organisms, distribution, competition and cooperation between different species are the major topics that fall under this field of study. The study of ecology can be structured by organizing the biological world into a nested hierarchy, that ranges in scale from genes to cells, organs, organisms, species and so on, up to the level of the biosphere. The practical applications of this field can be found in natural resource management, conservation biology, city planning, and wetland management, among many others. This book unfolds the innovative aspects of ecology that will be crucial for the progress of this field in the future. It consists of contributions made by international experts. Also included herein is a detailed explanation of the various concepts and applications of this field. Those in search of information to further their knowledge will be greatly assisted by this book.
