Summary
Ship transport alters marine biofilms, but hull coatings, not transport method, primarily influence future macrofouling. This impacts species distribution and invasion success.
Area of Science:
- Marine biology
- Ecology
- Biogeography
Background:
- Biofilms, including diatoms, are crucial in marine macrofouling and can be transported globally via ships.
- Understanding how transport affects biofilm structure and subsequent colonization is vital for predicting species dispersal and invasion.
Purpose of the Study:
- To investigate how different ship hull coatings and transport methods influence the composition of transported marine diatom biofilms.
- To determine the impact of these altered biofilms on subsequent macrofouling community structure and larval recruitment.
Main Methods:
- Transporting coastal marine biofilms under varying conditions (ship hull vs. sheltered) and across different salinity levels.
- Analyzing changes in diatom assemblage composition due to hydrodynamic stress and transport duration.
- Assessing the effect of the underlying hull coatings and transported biofilms on macrofouling species recruitment.
Main Results:
- Hydrodynamic stress during hull transport caused significant cell loss and altered diatom assemblage composition.
- Sheltered transport, even through freshwater, largely preserved the original biofilm composition.
- Hull coatings significantly shaped distinct macrofouling communities, affecting recruitment for a third of species, while transport treatments had minimal impact.
Conclusions:
- Ship transport conditions can modify diatom assemblages within biofilms, but the characteristics of the ship hull coatings are the primary drivers of subsequent macrofouling.
- These findings have significant implications for understanding the distribution, establishment, and invasion success of marine organisms transferred by shipping.
