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 matched custom photometry and environment metrics for a ~10x larger volume. In its smaller volume, RESOLVE adds extra-deep UV and 21cm data, spatially resolved optical spectroscopy, and enhanced completeness. In this talk I will focus on results from RESOLVE and ECO that illuminate links between the "baryonic" physics of gas and star formation and the "cosmological" physics of growing dark matter halos. Transitions in halo gas heating at the "gas-richness threshold" and "bimodality" halo masses (roughly 10^11.4 Msun and 10^12.1 Msun) delineate regimes of rapid accretion-driven galaxy growth for isolated dwarf galaxies, decelerating growth and dwarf destruction for "nascent" few-member galaxy groups, and quenching for massive groups. These transitions create complex group halo-mass dependence in the galaxy mass function, hidden within its deceptively simple global form, and dovetail with the emergence and disappearance of dwarf shortfalls and missing baryons, respectively. I will end with a brief overview of complementary RESOLVE/ECO science probing mechanisms of galaxy building and destruction on both larger (cosmic web) and smaller (neighbor interaction) scales.
