Massive neutrinos have peculiar effects on several observables in current and future redshift surveys. A precise determination of them is crucial not only to constraint properly neutrino masses but also to avoid potential systematic errors in the determination of other cosmological parameters, e.g. the dark energy equation of state.

In this talk, after a brief review of linear theory results, I will discuss, with the help of a large suite of N-body simulations, the effect of massive neutrinos on different cosmological probes, like the abundance of massive clusters, the non linear matter power spectrum and its relation to the galaxy power spectrum, redshift space distorsions, and the bispectrum.
