Position of Fornax and Hydra galaxies with respect to the dwarf fundamental plane (FP) defined by 50 star-forming dwarf galaxies from the LV on which Virgo star-forming dwarfs are also plotted (McCall et al., in prep.). Last digits for Fornax and Hydra galaxies are labeled. Typical error bars of 0.4 mag are plotted in the upper-left corner. Only two objects appear close to the plane (one from each cluster), while most Hydra galaxies are located outside, suggesting some enviromental effects.
