In this response we have incorporated data on gastropod and seaweed biodiversity referred to by Avila et al. ( 2016, Journal of Biogeography, doi:10.1111/jbi.12816) to allow an updated analysis on marine shallow-water biogeography patterns. When compared to the biogeography patterns reported in Hachich et al. ( 2015, Journal of Biogeography, 42, 1871-1882), we find ( 1) no differences in the patterns originally reported for reef fish or seaweeds, ( 2) minor differences in gastropod species-area and species-age patterns and ( 3) a significant difference for the gastropod species-isolation pattern. In our original work, we reported that there was limited evidence that gastropod species richness was influenced by island isolation; however, our new analysis reveals a power-model relationship between these variables. Thus, we are now able to conclude that gastropod species diversity, whose dispersal capacity is intermediate between seaweeds ( lowest) and reef fish ( highest), is also influenced by island isolation.431225172519
