Summary 
This book facilitates research in the general area of population dynamics by presenting some of the recent developments involving theories, methods and application in this important area of research. The underlying common feature of the studies included in the book is that they are related, either directly or indirectly, to the wellknown LotkaVolterra systems which offer a variety of mathematical concepts from both theoretical and application points of view
