Resumen:
Non-indigenous species (NIS) are prominent constituents of fouling communities. NIS can cause biodiversity lossand change community structure through the local elimination of native species. Ports are the main focus of NISand artificial structures are becoming spots of introduction. Community composition can vary with depth andtime. In this context, this work aimed to assess substrate (concrete and wood), vertical position (near-surface andnear-bottom) and month variations on the abundance of fouling invertebrates´ assemblages represented by native,NIS and cryptogenic species within the Mar del Plata port, Argentina. Monthly subtidal samples were takenscraping from fouling assemblages on substrates and vertical position in the port. Assemblages on substrate,depth and time showed similar species composition patterns. Native, NIS and cryptogenic species vary in meanabundances on each substrate, depth and month. Diversity indices on concrete and on near-bottom revealedhigher values. High species specific response of NIS (compared to native), found in this study along the temporalfluctuations in fouling communities was registered. A long term monitoring and future studies might considerincluding more substrates type and an intermediate depth, since they will provide better knowledge about thefouling invasions.
