Regional Impacts
| Ecological Impact | Toxic | |
| Bioturbation by Marenzelleria neglecta resulted in increased release of toxic organic compounds from sediments in the Stockholm archipelago(Granberg et al. 2008). | ||
| Ecological Impact | Bioturbation | |
| Irrigation of sediments by Marenzelleria neglecta may result in the oxygenation of sediments, enhancing retention of phosporus in sediments, while reducing the concentration of labile orgnanc compounds (Norkko et al. 2012). | ||
| Ecological Impact | Habitat Change | |
| Irrigation of sediments by Marenzelleria neglecta has led to an increase in oxygen levels of sediments, increasing phosphorus retention in sediments, and reducing hypoxia due to eutrophication in the Stockholm archipelago (Norkko et al. 2012) | ||
