In my talk, I will present brief synopses of supersymmetric models where either the neutralino composition or its mass is adjusted so that thermal relic neutralinos saturate the measured abundance of cold dark matter in the universe. The goal of our work is to correlate relic-density-allowed parameter choices with expected phenomena in direct, indirect and collider dark matter search experiments. We find that many implications about sparticle properties and collider signals drawn from the analysis of the relic density constraint within mSUGRA do not carry over to simple one-parameter extensions of the mSUGRA framework. And we show that in a large number of cases the mechanism that causes the early universe neutralino annihilation rate to be large also enhances the direct rate, and often also the rates for indirect detection of neutralino dark matter.
