From top to bottom: M_HI/M_⋆, M_H2/M_⋆, and M_H2/M_HI as a function of morphology for Virgo filament galaxies (center), AMIGA isolated galaxies (left), and Virgo cluster galaxies (right). Points are color coded according to local density n₅. Triangles show the binned median values, while their error bars correspond to the rms dispersion around the median; equally spaced bins with at least five points each have been considered. In the bottom row, we do not plot a source if both the HI and H₂ masses are upper limits.
