Ecosystem Services and Global Ecology
Ecosystem services as a concept plays a key role in solving global environmental and human ecological crises and associated other problems, especially today when the sixth major extinction event of the history of the biosphere is in progress, and humanity can easily become a victim of it. The aim of this book is to give an overview and report from the frontiers of research of this important and interesting multidisciplinary area.
