  Three dimensional computations of self consistent three species gyrofluid
turbulence are carried out for tokamak edge conditions. Profiles as well as
disturbances in dependent variables are followed, running the dynamical system
to transport equilibrium. The third species density shows a significant
correlation with that of the electrons, regardless of initial conditions and
drive mechanisms. For decaying systems the densities evolve toward each other.
Companion tests with a simple two dimensional drift wave model show this
persists even if the third species is a passively advected test field.
Similarity in the transport character of electrons and the trace species does
not imply that the electrons themselves have a test particle transport
character.
