Lyrodus pedicellatus replaced Teredo navalis as the dominant shipworm attacking wood in the Tagus estuary, Portugal, in surveys (~1994-2010), compared to earlier surveys conducted in the 1960s-1970s. Increases in average temperature and salinity in the estuary may favor L. pedicellatus (Borges et al. 2011). | ||
