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.

This book, Landscape Ecology has written
to present major and efficient applications in landscape ecology, as well as to
propose a solid action for this category of topics. The book aims to illustrate
various treatment methods of the land-use models impact on landscape ecology
creation.
