In the summer of 1876, Mark Twain started to write Adventures of Huckleberry Finn as a detective novel surrounding the murder of Huck’s father, Pap Finn. The case is unresolved in the novel as it exists today, but Twain had already planted the clue to the identity of the killer. It is not the various objects ostentatiously left around Pap’s naked body; they are not the foreground of the scene, but actually the background, against which a peculiar absence emerges distinctively—Pap’s boots, with a "cross" in one of the heels, are gone with his murderer.The key to the mystery of Twain’s writings, as this book contends from a broader perspective, is also such an absence. Twain’s persistent reticence about the death of his father, especially the autopsy performed on his naked body, is a crucial clue to understanding his works. It reveals not only the reason why he aborted his vision of Huckleberry Finn as a detective novel, but also why, despite numerous undertakings, he failed to become a master of detective fiction.

Mathematical ecology is a subject which recently attracts attentions of many mathematicians and biologists. One of the most important and fundamental mathematical models in ecology is of Lotka-Volterra type. This book gives global dynamical properties of L-V systems. The properties analyzed are global stability of the equilibria, persistence or permanence of the systems (which ensures the survival of all the biological-species composed of the systems for the long term) and the existence of periodic or chaotic solutions. The special subject of this book is to consider the effects of the systems structure, diffusion of the biological species and time delay on the global dynamical properties of the systems.
