New threats of an old enemy: The distribution of the shipworm Teredo navalis L. (Bivalvia: Teredinidae) related to climate change in the Port of Rotterdam area, the Netherlands

► We examine the distribution of shipworms in estuaries due to global warming. ► Decreasing precipitation in summer and fall decreases river discharge. ► Lower river discharge extends the salinity gradient. ► Longer salinity gradient extends the distribution of shipworms stream upwards. ► Distribution extension increases the risk of damage of wooden structures.
