European water frog populations are mainly composed by two species: Pelophylax lessonae (pool frog) and Pelophylax esculentus (edible frog). These populations are called L-E complexes. Edible frogs are a hybrid form between P. lessonae and Pelophylax ridibundus (eastern lake frog) and they reproduce in a particular way, called hybridogenesis. These frog populations have been studied in the contexts of evolution and speciation. In order to have stability of L-E complexes (namely self-maintainance of the population structure) some conditions are necessary. We present a computational formal model of European water frog population based on a variant of P systems in which evolution rules are applied in a probabilistic maximally parallel manner. Probabilities of application of rules are computed on the basis of parameters to be associated with each rule. By means of our model we show how the stabilization of L-E complexes can be obtained. In particular, we show how the introduction of translocated eastern lake frogs in such complexes can lead to the collapse of the populations.

Short Bio:
Pasquale Bove holds a B.Sc. from the University of Pisa and is currently a PhD student at the Department of Computer Science of the University of Pisa. His research focuses on individual based modeling and analysis of real macroscopic biological problems based on a computational formalism derived from P-systems. He works in the research group of Prof. R. Barbuti, Prof. P. Milazzo, Prof. Andrea Maggiolo-Schettini and Prof. G. Pardini and he has alrady published 2 papers on the topics of his thesis.
