  The phenomenon of spatial clustering induced by death and reproduction in a
population of anomalously diffusing individuals is studied analytically. The
possibility of social behaviors affecting the migration strategies has been
taken into exam, in the case anomalous diffusion is produced by means of a
continuous time random walk (CTRW). In the case of independently diffusing
individuals, the dynamics appears to coincide with that of (dying and
reproducing) Brownian walkers. In the strongly social case, the dynamics
coincides with that of non-migrating individuals. In both limits, the growth
rate of the fluctuations becomes independent of the Hurst exponent of the CTRW.
The social behaviors that arise when transport in a population is induced by a
spatial distribution of random traps, have been analyzed.
