Kurzbeschreibung
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 sogenannten 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.
