The aim of this paper is to present an original modelling tool for biogeographical systems. This software named LUCAS (LUcifer Cellular Automata Simulator) has been developed within the European programme LUCIFER (Land Use Change Interactions with Fire in MeditERrranean landscapes). LUCAS constitutes general software, based on coupling local dynamics(More)
The emergence of new species is one of the trickiest issues of evolutionary biology. We propose a cellular automata model to investigate the possibility that speciation proceeds in sympatry, focusing on the importance of the structure of the landscape on the likelihood of spe-ciation. The conditions for speciation are shown to be limited whatever the(More)
