Predicting free-space occupancy on novel artificial structures by an invasive intertidal barnacle using a removal experiment.

Artificial structures can create novel habitat in the marine environment that has been associated with the spread of invasive species. They are often located in areas of high disturbance and can vary significantly in the area of free space provided for settlement of marine organisms. Whilst correlat...
