Abstract

This dataset contains data described in the paper entitled "Biogeographic drivers of distribution and abundance in an alien ecosystem engineer: Transboundary range expansion, barriers to spread, and spatial structure". Data include: (1) historical and contemporary records of the invasive mussel Mytilus galloprovincialis to re-construct its invasion history and patterns of spread across biogeographic regions of southern Africa; (2) densities of M. galloprovincialis at different shore heights measured from multiple sites across South Africa; (3) semi-quantitative (ACFOR) abundance values of M. galloprovincialis estimated from multiple sites across South Africa; (4) measurements taken of individual mussels to compare population size structure, characterisation of endolithic infestation, and characterisation of epibionts on shells between range-edge and centre populations of M. galloprovincialis in South Africa; and (5) the GPS co-ordinates determined for every 1-km distance interval of the South African coastline starting from the mouth of the Orange River at the border of South Africa and Namibia.
