Abstract/Summary

Habitatmodificationcoupledwiththespreadofnon-nativespecies(NNS)areamongthetopthreatstomarine biodiversity globally. Species are known to be transported to new locations via international shipping and secondarily spread via regional vessels and artificial structures. Rapid Assessment Surveys (RAS) combining quantitativeandsemi-quantitativemethodscomparedNNSrichnessandassemblagecompositiononintertidal naturalrockyshoresandartificialstructuresinharboursindifferentregionsalongthesouthcoastofEngland. Quantitative data showed that artificial habitats supported higher richness than natural habitats, while semiquantitativedatafoundnodifferenceinrichnessamonghabitattypes.Thisresultwasattributedtoadditional species found in rock pools during searches of complex microhabitats in natural habitats. Assemblages on artificialstructuresdifferedamongregions,withregionsandharbourswithgreaternumbersofvesselssupporting greaterrichness.ResultshighlighttheimportanceofshippingandartificialstructuresforNNSintroductionand spread.
