Shell-size variation of Notoacmea biradiata (Archaeogastropoda: Acmaeidae) as a response to gastropod density and height in shore in the Colombian Pacific coast
Published 2002-03-01“…Intertidal gastropod density was found to be the dominant factor in determining basal shell length (ANOVA, P < 0.001) and shell height (ANOVA P < 0.05) changes. Thus, at low population densities the shells are larger and taller. The height on the shore did not influence the shell-size of N. biradiata (ANOVA, P > 0.30). …”
