Scattering length, which can be measured in Bose-Einstein condensate andFeshbach molecule experiments, is extremely sensitive to the variation offundamental constants, in particular, the electron-to-proton mass ratio(m_e/m_p or m_e/Lambda_{QCD}, where Lambda_{QCD} is the QCD scale). Based onsingle- and two-channel scattering model, we show how the variation of the massratio propagates to the scattering length. Our results suggest that variationof m_e/m_p on the level of 10^{-11}~10^{-14} can be detected near a narrowmagnetic or an optical Feshbach resonance by monitoring the scattering lengthon the 1% level. Derived formulae may also be used to estimate the isotopicshift of the scattering length
