Summary

Researchers calculated Shannon and Simpson diversity indices for microplastic assemblages at 61 sites across the St. Lawrence River and Estuary using the vegan package, applying permutational ANOVA to assess variation by site and area using two net mesh sizes. This supplementary dataset supports broader analysis of microplastic community composition across fluvial and estuarine zones in Canada.

Study Type Environmental

Shannon and Simpson diversity index for site and area using the vegan package with function “adonis” (n = 61). Permutations were set at 999. (DOCX)
