We use a volume-, magnitude-limited sample of nearby galaxies to investigate the effect of the environment on the Hi scaling relations. We confirm that the Hi-to-stellar mass ratio anti correlates with stellar mass, stellar mass surface density and NUV r colour across the whole range of parameters covered by our sample (10 9 < �M∗ < �10 11 M⊙, 7.5 < �µ∗ < �9.5 M⊙ kpc −2 , 2 < �NUV r < �6 mag). These scaling relations are also followed by galaxies in the Virgo cluster, although they are significantly offset towards lower gas content. Interestingly, the difference between field and cluster galaxies gradually decreases moving towards massive, bulge-dominated systems. By comparing our data with the predictions of chemo-spectrophotometric models of galaxy evolution, we show that starvation alone cannot explain the low gas content of Virgo spirals and that only ram-pressure stripping is able to reproduce our findings. Finally, motivated by previous studies, we investigate the use of a plane obtained from the relations between the Hito-stellar mass ratio, stellar mass surface density and NUV r colour as a proxy for the Hi deficiency parameter. We show that the distance from the ‘Hi gas fraction plane’ can be used as an alternative estimate for the Hi deficiency, but only if carefully calibrated on pre-defined samples of ‘unperturbed’ systems.

Cold gas stripping in satellite galaxies: from pairs to clusters (2016, methodology): “…show that reservoirs are adversely affected in the highest density environments such as galaxy clusters (Giovanelli & Haynes 1985; Chung et al. 2009; Cortese et al. 2011; Serra et al. 2012), and that gas processing begins to occur within the group environment (Kilborn et al. 2009; Rasmussen et al.…”
The SAMI Galaxy Survey: Instrument specification and target selection (2014, result): “Indeed, compared with the average Hi scaling relations of local galaxies (Cortese et al. 2011), the SAMI galaxies in the ALFALFA catalogue clearly occupy the gas-rich envelope of the M(Hi)/M∗ vs. stellar mass scaling relation of nearby galaxies (see Figure 15, lower).”
VALIDATION OF THE EQUILIBRIUM MODEL FOR GALAXY EVOLUTION TO z ∼ 3 THROUGH MOLECULAR GAS AND DUST OBSERVATIONS OF LENSED STAR-FORMING GALAXIES (2013, background): “Not only do we know locally that the HI fractions increase as stellar masses decrease (Catinella et al. 2010, 2012; Cortese et al. 2011; Huang et al. 2012), it can also be expected that the gas surface densities are lower in the z > 2, logM∗/M⊙ ∼ 10 lensed galaxies than in others at the high-mass…”

The neutral hydrogen content of galaxies in cosmological hydrodynamic simulations (2013, background): “But even galaxies that still have substantial H i show correlations of their H i content with properties such as environment (e.g. Cortese et al. 2011), and metallicity (Robertson, Shields, & Blanc 2012).”
THE ARECIBO LEGACY FAST ALFA SURVEY: THE GALAXY POPULATION DETECTED BY ALFALFA (2012, methodology): “Moreover, as pointed out in Cortese et al. (2011), the distribution offHI is closer to log-normal than Gaussian, and thus they also prefer〈log fHI〉 to log〈fHI〉.”
