Spatial Ecology Via Reaction-Diffusion Equations

• Gebundenes Buch

Produktbeschreibung

Viele Probleme aus der Ökologie, darunter zum Beispiel die Ausbreitung von Schadstoffen, lassen sich modellieren, wenn man auf scheinbar zufällige Prozesse mit einer räumlichen und gegebenenfalls auch einer zeitlichen Dimension zurückgreift. Dieses Buch zeigt Ihnen, wie man räumliche Effekte in der Ökologie und Populationsdynamik mit so genannten Reaktions-Diffusions-Modellen beschreiben kann. Sie lernen, Modelle aufzubauen und die Resultate zu interpretieren. Die Umsetzung der Theorie in die Praxis wird anhand spezieller Anwendungsbeispiele demonstriert.

Rezensionen

"...particularly attractive and useful for graduate students and other researchers who are interested in studying applications of reaction-diffusion theory to spatial ecology." ( Mathematical Reviews , Issue 2007a)
"...I would recommend this book to anyone who wants a well supported journey into the modern theory of partial differential equations and dynamic systems..." ( The Mathematical Gazette , March 2005)
