DOIAbstract
We present observations of 18 galaxies from the Galaxy And Mass Assembly (GAMA) survey made with the SPIRAL optical integral field unit (IFU) on the Anglo-Australian Telescope. The galaxies are selected to have a narrow range in stellar mass (6 x 10⁹ 0.77 Mpc⁻²), and 5/11 (45+15-13 per cent) galaxies in low-density environments (<0.77 Mpc⁻²). We find a weak but not significant relationship of the total SFRs of star-forming galaxies with environment. Due to the size of our sample and the scatter observed we do not draw a definitive conclusion about a possible SFR dependence on environment. Examining the spatial distribution of the Ha emission, we find no evidence for a change in shape or amplitude of the radial profile of star-forming galaxi...
