Regional Impacts
| Ecological Impact | Habitat Change | |
| Some habitat impacts (Zaiko et al. 2011), mostly due to burrowing and bioturbation. | ||
| Ecological Impact | Bioturbation | |
| In experiments, fluxes of TCO2 and O2 increased in the presence of Marenzelleria and were higher when plant detritus was added to sediments. Marenzelleria stimulated carbon degradation and sulfate reduction by influencing pore water chemistry and dissolved organic carbon. Marenzelleria flushed out inhibitory pore water chemicals (CO2, H2S and NH4; Quintana et al. 2013; Quintana 2018). | ||
