Macro-species taxonomy measured through a multi-factorial in situ experiment of 10 weeks in a eelgrass bed in St. Lawrence Estuary (Baie-Saint-Ludger, Canada)

We evaluated single and interactive effects of density reduction of Zostera marina L., a habitat-forming species, shading, and sediment nutrient enrichment on the response of intertidal epibenthic macro-species. Epibenthos was collected using mesh bags (mesh size of 500 µm, diameter about 18 cm). This dataset reports all species identified through the experiment and their taxonomic classification.
