P-Lingua is a programming language for membrane computing. It was rst
presented in Edinburgh, during the Ninth Workshop on Membrane Computing (WMC9).
In this paper, the models, simulators and formats included in P-Lingua in version 2.0 are
explained. We focus on the stochastic model, associated simulators and updated features.
Finally, we present two new applications based on P-Lingua 2.0: a tool for describing and
simulating ecosystems and a framework (currently under development) for P systems
design.Ministerio de Educación y Ciencia TIN2006–13425Junta de Andalucía P08-TIC-0420
