Book Description
As a diffusion process in an ecosystem tends to give rise to a uniform density of population in space, it may be expected that diffusion plays a general role of increasing the stability in a system of mixed populations and resources. However, diffusion may also induce an instability to a system which is basically stable without diffusion. Thus a system of two interacting and diffusing populations both being co-existent in a spatially uniform distribution, hence with no patterns, may exhibit an interaction-diffusion instability. The instability results in a form of biological waves in space and time, thus leading to a 'patchiness.' (Author).

Book Description
The planning for the conference held at Erice, Sicily, in November 1977, began with discussions among oceanographers from several countries on the need to consider the special problems and the recent results in the study of plankton "patchiness. " An approach to the Marine Sciences Panel of the NATO Science Committee resulted in a planning grant to determine the probable content and participation in such a meeting. The planning group consisted of B. Battaglia (Padua), G. E. B. Kullenberg (Copenhagen), A. Okubo (New York), T. Platt (Halifax, Nova Scotia) and J. H. Steele (Aberdeen). The group met in Aberdeen, Scotland, in September 1976. The proposal for a NATO School on the subject of "Spatial Pattern in Plankton Communities" was accepted by the Marine Science Panel and it was agreed that it be held at the Ettore Majorana Centre for Scientific Culture in Erice. The Centre began in 1963 with an International School of Subnuclear Physics and has since developed to include courses in many other subjects which cover various fields of basic and applied research. The original aim of the . Centre was to create, in Italy, a cultural forum of high scientific standard which would allow young research workers to appreciate problems currently of major interest in various fields of research.

Book Description
Surveying a wide variety of mathematical models of diffusion in the ecological context, this book is written with the primary intent of providing scientists, particularly physicists but also biologists, with some background of the mathematics and physics of diffusion and how they can be applied to ecological problems. Equally, this is a specialized text book for graduates interested in mathematical ecology -- assuming no more than a basic knowledge of probability and differential equations. Each chapter in this new edition has been substantially updated by appopriate leading researchers in the field and contains much new material covering recent developments.
