This book brings together chapters related to sustainable utilization of biological resources, including in situ and ex situ conservation of rare, endangered, and threatened plants. The title also gives a special emphasis on marine sponges and mangrove ecosystems, which are two important untapped potential resources of the marine ecosystem and play a key role in maintaining the marine ecosystem. There is an urgent need for the conservation, exploration and utilization of bioresources for the growth and survival of human beings. Due to the significant reduction in biological resources, many countries are developing strategic action plans for the conservation and sustainable use of biological resources. That is where this book fills the gap by discussing the significant development of new products and methodologies for sustainable utilization of these resources. This book also unveils a world of novel bioactive molecules from medicinal plants and the marine ecosystem and explains how drug design pipelines can advance modern drug development. The target audiences for this book include biodiversity researchers who are working on technology and bioresource management issues and faculty and students in the environment research areas and Biodiversity conservation.
