%X Although the process by which galaxies obtain the gas needed for star-formation is amongst the  most fundamental processes related to the formation of baryonic structure in the universe, there  is very little in the way of empirical evidence with which to constrain theoretical models. In particular,  the postulated environmental dependencies of this process, although widely modeled,  remain largely unconstrained. In this work, I present the first detailed, quantitative analysis  of the environmental effects on the process of gas-fueling in which the relevant effects of the  galaxy - intergalactic medium interaction have been isolated from other potential environmental  in  uences. In the context of this analysis, a new robust method for selecting morphologically  defined samples of galaxies by photometric proxies is developed, as well a powerful new method  for correcting the UV/optical emission of samples of spiral galaxies for the effects of attenuation  by dust located in their disks. Combining these tools with the data from the GAMA  survey, in particular the galaxy group catalog, I present a detailed analysis of the environmental  dependencies of gas-fueling. The results obtained require a fundamental re-evaluation of the  assumptions concerning the fueling of satellite galaxies and the effects of active galactic nuclei.
