Figure 5From: Importance of plasticity and local adaptation for coping with changing salinity in coastal areas: a test case with barnacles in the Baltic SeaEffects of salinity on shell strength. Effects of salinity on shell strength in barnacles from different populations (Stockholm, Kiel and Tjärnö) that were grown in different salinity treatments (mean ± SE, n = 4). Shell strength was standardised by dividing the force required to break the shell (in MPa) by the maximum shell diameter of each barnacles.Back to article page
