The environmental effects on galaxy evolution have recently been disputed based on large SDSS galaxy samples but these effects are still expected to be strong for low-mass galaxies. We obtained deep near-infrared imaging of irregular dwarfs in Cen A, M 81 and Sculptor groups – spanning a range of galaxy density, – and we study the properties of these dwarfs, i.e. abundance, chemical evolution, and structural parameters. Here we give a preliminary assessment of the structural parameters for these galaxies.
