The one-loop contribution to vacuum polarization is calculated for theadjoint fermions in three dimensional noncommutative spaces, both at zero andfinite temperature. At zero temperature, we confirm a previously found resultfor the parity odd part and subsequently analyze the even parity part, whichexhibits UV/IR mixing. We discuss in detail, two regimes of the hightemperature behavior of the parity odd part. When the thermal wavelength ismuch smaller, as compared to the noncommutativity scale, we find an interestingFermi-Bose transmutation in the nonplanar part.Comment: 15 pages, minor corrections and references added (version to appear in JHEP
