  We give some estimates for the light-quark mass dependence of the pole
position of the sigma ($f_{0}(500)$) resonance in the complex energy plane,
with the help of a chiral Lagrangian for the resonance field and some input
from hadronic models constrained by Chiral Perturbation Theory and elastic
unitarity. We also speculate on the fate of the sigma resonance when the quark
masses become unphysically large.
