Item Community and marine conservation in South Africa: Are we still missing the mark?(Frontiers Media, 2022) Peer, Nasreen; Muhl, Ella-Kari; Brown, MichaelMarine Protected Areas (MPAs) in South Africa have a long history with currently 5% of the mainland’s ocean territory protected. The MPAs are celebrated and appreciated for their representative coverage of several habitat types and their ecological benefits. However, the story of correlational coastal community exclusion is not one that is often told in the ‘success’ story of South African MPAs. In this review we describe the history of marine conservation in South Africa and examine how the legislation and motivation has evolved since Apartheid.Item Kelp holdfasts in the Great African Seaforest provide habitat for diverse assemblages of macroinvertebrates(Inter-Research, 2024) Samaai, Toufiek; Katharoyan, Chaitanya; Peer, NasreenKelp forests along the southwestern and west coasts of South Africa, dominated by the species Ecklonia maxima and Laminaria pallida, are locally termed ‘the Great African Seaforest’. They form 3-dimensional biogenic habitats that provide 4 distinct microhabitats—canopy, fronds, stipe and holdfast—with the latter typically supporting the highest abundance and diversity of associated macroinvertebrates. The macrofauna inhabiting kelp holdfasts in South Africa have rarely been studied, resulting in a near complete lack of baseline data. In this study, macrobenthic assemblages from 40 E. maxima holdfasts were examined over 2 marine ecoregions and 4 locations. Macroinvertebrates were identified and counted for univariate and multivariate analyses using family-level data. A total of 120 families from 9 phyla were identified and were generally dominated by Arthropoda (48 families), Annelida (24 families) and Mollusca (23 families). Marine ecoregion had no significant effect on composition of macroinvertebrate assemblages, whereas location had a significant effect. There was no significant relationship between holdfast volume and macroinvertebrate diversity or abundance, suggesting that other environmental and physicochemical factors are important in determining community structure. This study serves as a baseline for future research aimed at understudied holdfast macroinvertebrate communities in the Great African Seaforest.
