we present a discrete dynamical population modeling of invasive species, with reference to the swamp crayfish Procambarus clarkii. This model is based on a structure with 7 age classes, i.e. a Leslie mathematical population model. The sensitivity analysis shows a good resilience of the model and, for low values of reproductive female fraction, the fluctuations may eventually lead to the extinction of the species. Finally, the spatial mobility is introduced in the model, simulating the movement of the crayfishes in a virtual lake of elliptical form by means of simple cinematic rules encouraging the movement towards the banks of the catchment.

Abstract

we present a discrete dynamical population modeling of invasive species, with reference to the swamp crayfish Procambarus clarkii. This model is based on a structure with 7 age classes, i.e. a Leslie mathematical population model. The sensitivity analysis shows a good resilience of the model and, for low values of reproductive female fraction, the fluctuations may eventually lead to the extinction of the species. Finally, the spatial mobility is introduced in the model, simulating the movement of the crayfishes in a virtual lake of elliptical form by means of simple cinematic rules encouraging the movement towards the banks of the catchment.
