One study on the human presence in the Porto de Galinhas reef (Northeast Coast, Pernambuco) found that marine trampling had led to severe changes on the meiofauna. The total density and the most frequent group were negatively affected, indicating that the loss of little known species is one of the potential consequences of human trampling of coral reefs (Sarmento & Santos, 2012).
Spatiotemporal variations in prey assemblages were not assessed in this study; however, prior investigations in the Narragansett Bay have revealed substantial changes in abundances of benthic meiofauna and macrofauna across sites and seasons (Rudnick et al., 1985; Calabretta and Oviatt, 2008), and some of these fauna constitute important prey for juvenile winter and summer flounder (e.g., harpacticoid copepods, polychaetes, nematodes, and bivalves).
