Abstract: Using a dynamic model of Lake Chozas developed by Marchi et al. (2011), we tested three hypotheses about recovery of the indigenous community and water quality after radical changes caused by introduction of an invasive allochthonous crayfish, Procambarus clarkii:1.Can the lake resist the pressure of an invasive species, like P. clarkii, by adaptation?2.Can the ecosystem recover when all the crayfish are removed and low phosphorus concentrations persist in inflow water?3.Does the simulated recovery of submerged vegetation occur at a total phosphorus concentration below 100mgTPm−3, as estimated by Scheffer et al. (1993), Scheffer (1997), Jeppesen et al. (1998) and Zhang et al. (2003)?
