(29.38%) ({C}hlorophyceae). {I}n 2022, copepods (76-92%) were most abundant on {S}argassum spp. and {U}lva spp., which had washed up on the beach. {A} significant link between epifaunal abundance and macroalgae species highlighted their ecological interdependence. {T}hese findings are of relevant interest for {W}est {A}frica's blue economy, where the growing exploitation of wild macroalgae could disrupt these ecosystems. {S}ustainable management must take into account epifaunal species, particularly those found on structurally important macroalgae (e.g., {C}orallina sp., {C}odium sp.). {T}he study recommends including macroalgae-epifauna associations in biodiversity inventories, particularly in marine protected areas, and continuing research on influencing factors (e.g., algal morphology, environmental conditions). {M}ass strandings of {S}argassum spp. and {U}lva spp. can cause mortality in marine larvae and eggs, leading to a local reduction in recruitment. {F}uture research integrating these conclusions could allow a more detailed analysis of the epifauna on macroalgae. {E}cosystem approach is essential to strike a balance between economic development and biodiversity conservation.}, keywords = {{ATLANTIQUE} ; {CAP} {VERT} ; {DAKAR} ; {SENEGAL}}, booktitle = {}, journal = {{D}iversity}, volume = {18}, numero = {3}, pages = {133 [16 ]}, ISSN = {1424-2818}, year = {2026}, DOI = {10.3390/d18030133}, URL = {https://www.documentation.ird.fr/hor/fdi:010096819}, }
