    "abstract": "In a model for rotating non-Boussinesq convection with mean flow we identify\na regime of spatio-temporal chaos that is based on a hexagonal planform and is\nsustained by the {\\it induced nucleation} of dislocations by penta-hepta\ndefects. The probability distribution function for the number of defects\ndeviates substantially from the usually observed Poisson-type distribution. It\nimplies strong correlations between the defects inthe form of density-dependent\ncreation and annihilation rates of defects. We extract these rates from the\ndistribution function and also directly from the defect dynamics.",
