    "abstract": "We study a master equation system modelling a population dynamics problem in\na lattice. The problem is the calculation of the minimum size of a refuge that\ncan protect a population from hostile external conditions, the so called\ncritical patch size problem. We analize both cases in which the particles are\nconsidered fermions and bosons and show using exact analitical methods that,\nwhile the Fermi-Dirac statistics leads to certain extinction for any refuge\nsize, the Bose-Eistein statistics allows survival even for the minimal refuge.",
