The MAUVE (MUSE and ALMA Unveiling the Virgo Environment) Survey is a large multi-wavelength program investigating how environment influences the gas-star formation cycle in Virgo cluster galaxies. Combining new VLT/MUSE optical integral field spectroscopy and ALMA CO(2-1) mapping, MAUVE systematically probes the full extent of the molecular gas disks in 40 late-type Virgo Cluster galaxies at various infall stages on the scale of individual star-forming regions and molecular clouds. In this talk, I will present new results from MAUVE that reveal systematic differences in the ionized gas properties between cluster and field galaxies. Using spatially resolved emission-line diagnostics and velocity dispersion measurements, we show that Virgo cluster galaxies exhibit a significant reduction in star formation-driven HII region ionization compared to field galaxies. This is accompanied by a strong enhancement of high-dispersion, non-HII ionization sources, consistent with shocks, diffuse ionized gas, and post-AGB heating. These findings highlight how Virgo's environmental processes transform the ISM, suppressing star formation while enhancing alternative ionization mechanisms, ultimately driving galaxy quenching.
