The clusters derive from the Red-sequence Cluster Survey (RCS) and the Spitzer Adaptation of the Red-sequence Cluster Survey (SpARCS), and possess ample spectroscopic coverage, yielding numerous confirmed cluster members. This thesis consists of a collection of distinct but related works, focusing on environmental effects within the dense regions of clusters---some of the rarest structures in the Universe. We exploit the high sensitivities of cutting-edge infrared and submillimeter telescopes to glean the wealth of information encoded within the thermal portion of the spectral energy distribution, including infrared luminosities and dust temperatures. This allows us to uncover various trends within the star-forming population as a function of environment. Moreover, we develop a novel definition of environment, based on the phase space of radius and velocity, to account for the various accretion histories of galaxies onto clusters; it thereby probes the time-averaged density that each galaxy population has experienced. Using this tracer of environment, we find a significant depression in the star formation rate per unit stellar mass for star-forming galaxies within cluster cores at z~0.9 and z~1.2, in contrast to the flat trend that results from conventional definitions of environment. We also discover a population of galaxies that have lower dust temperatures compared to both infalling galaxies and those that were accreted at the earliest stages of the formation of the cluster. Taken together, these trends in star formation rate and dust temperature can help elucidate which, if any, quenching mechanisms are active within cluster environments. Finally, we report the serendipitous detection of an overdensity of submillimeter-bright galaxies located behind a merging z~0.9 supercluster, which could signify a highly star-forming protocluster at z~3." --
