Chaos in Ecology: Experimental Nonlinear Dynamics, Theoretical Ecology Series, Vol. 1, Academic Press (Elsevier Science), New York, 2003, ISBN: 0-12-1988767 (jointly with R. F. Costantino, B. Dennis, R. A. Desharnais, S. M. Henson)

“In
terms of what they
reveal about the mechanisms of population growth, about nonlinear
stage-structured population models, and about chaos in ecology, these
experiments are on the level of the classic works of Gause, Nicholson,
Park, and Huffaker. In terms of the integration of experiment
and
theory, they surpass even those studies. Anyone interested in the
dynamics of populations will benefit from reading this book."
--
Hal Caswell, Ecology
(2003)

“This is the definitive source on chaos in ecology. Well-written and authoritative. ” -- Simon Levin, Princeton University 2002

“The authors have made very circumspect model verifications...The greatest merit of the book is that it confirms experimentally the existence of numerous nonlinear phenomena in populations and presents a new characteristic of populations, that is, the lattice effect. The book is written in an excellent style with high mathematical precision. This work is warmly recommended to all theoretical and field ecologists, and all scientists interested in nonlinear dynamics.” -- Community Ecology (2005)

“... rich in statistical concepts and methods. Anyone interested in the dynamics of populations will benefit from reading this book.” -- Ecology (2003)

“... an elegant blend of mathematics, statistics, and biology...” -- Chance (Fall 2003)
