Ecological Impact | Bioturbation | |
Burrowing activitity of M. neglecta results in reworking of sediment particles and increased irrgiation of sediments, increasing oxygenation and the exchange of solutes. The higher density of worms and higher rates of irrigation suggest that the impact of M. neglecta is greater than that of the native polychaete Hediste diversicolor (Hedman et al. 2011). | ||
