Resumo: | In recent years an increased shift in the geographical range of species has been documented, which coincides with global warming. On the Portuguese coast the raising of sea-surface temperatures and salinity has also been affecting the intertidal species range. The aim of the present study was to assess changes in the wood boring community present in the Tagus Estuary by comparing data from present surveys with historical records from the 1960s and 1970s. A shift in the activity of wood boring species was observed in the Tagus Estuary. In recent surveys, the main agents of wood destruction in the Tagus were Limnoria tripunctata and Limnoria quadripunctata. In the 1960s and 1970s only L. tripunctata was reported as occurring in the Tagus estuary but it was not considered at threat to wooden structures exposed in the sea. The present predominance of limnoriids in the Tagus might be related to several factors but possibly the most important was the increase in salinity in the area, as limnoriids appear to be restricted to waters with salinities closed to that of seawater. The teredinid species also changed in the area. In the 1960s and 1970s Teredo navalis was reported as the only teredinid species occurring in the Tagus. In recent surveys however, this species was not found, instead two other teredinid species were present Lyrodus pedicellatus and Nototeredo norvagica. The absence of T. navalis in recent surveys might be related to competition with L. pedicellatus. |

The aim of the present study was to assess changes in the wood boring community present in the Tagus Estuary by comparing data from present surveys with historical records from the 1960s and 1970s. A shift in the activity of wood boring species was observed in the Tagus Estuary. In recent surveys, the main agents of wood destruction in the Tagus were Limnoria tripunctata and Limnoria quadripunctata. In the 1960s and 1970s only L. tripunctata was reported as occurring in the Tagus estuary but it was not considered at threat to wooden structures exposed in the sea. The present predominance of limnoriids in the Tagus might be related to several factors but possibly the most important was the increase in salinity in the area, as limnoriids appear to be restricted to waters with salinities closed to that of seawater. The teredinid species also changed in the area. In the 1960s and 1970s Teredo navalis was reported as the only teredinid species occurring in the Tagus.
