Regional Impacts
| Ecological Impact | Competition | |
| Some community impacts (Zaiko et al. 2011). Off the Pomeranian coast of Poland, Mya arenaria and Macoma balthica often have an inverse relationship, suggestive of competition (Obolewski and Piesik 2005). | ||
| Ecological Impact | Habitat Change | |
| Some habitat impacts (Zaiko et al. 2011). Mya arenaria can alter sediment characteristics through bioturbation and deposition of pseudofeces (Obolewski and Piesik 2005). | ||
| Ecological Impact | Food/Prey | |
| Mya arenaria is a frequent food of European Flounder (Platichthys flesus) in the Baltic, off Lithuania (Bubinas and Vaitonis 2003), and of several flounder species off the Pomeranian coast of Poland (Obolewski and Piesik 2005). | ||
| Ecological Impact | Herbivory | |
| Inferred from large reported biomasses (Bubinas and Vaitonis 2003) and the reporting of 'some ecosystem impacts' (Zaiko et al. 2011). | ||
