The REsolved Spectroscopy Of a Local VolumE (RESOLVE) survey is a volume-limited census of stellar, gas, and dynamical mass as well as star formation and galaxy interactions within >50,000 cubic Mpc of the nearby cosmic web, reaching down to dwarf galaxies of baryonic (stellar + cold gas) mass ~10^9 Msun and up to galaxy groups/clusters and large-scale filaments, walls, and voids. The Environmental COntext (ECO) catalog surrounds RESOLVE, offering custom photometry and environment metrics obtained with the same pipelines for a ~10x larger volume. The smaller RESOLVE volume additionally offers extra-deep UV and 21cm data, spatially resolved optical spectroscopy, and enhanced completeness. In this talk I will present results from both RESOLVE and ECO that reveal surprisingly ubiquitous links between the "baryonic" physics of gas and star formation and the "cosmological" physics of multi-scale clustering in the cosmic web. These links challenge traditional wisdom on topics ranging from dwarf galaxy star formation efficiency to the environment dependence of galaxy mass functions.
