“…However, another major micrograzer species, Eulithidium afine , presented a pattern more similar to what was expected, with higher densities in Santa Rita and lower densities in Lamberto. CETESB annual reports have already registered high levels of heavy metals in sediment; Longo et al (2021) similarly registered higher concentrations of Cu, Zn, and Fe in Sargassum tissue from Lamberto beach than from the remaining sites studied herein, while Santa Rita levels were constantly lower. Many studies have demonstrated that different gastropod species accumulate heavy metals in their tissues, with potential effects on their physiology and population biology (Cunha et al, 2007; Gammon et al, 2009; Krupnova et al, 2018; Maher et al, 2016); this could potentially be affecting E. affine populations in Flamengo Bay, although further manipulative studies are fundamental to test this hypothesis.…”

“…In a previous study in Flamengo Bay that simultaneously evaluated heavy metal concentrations in Sargassum tissues and associated gastropod diversity, Longo et al (2021) found lower diversity levels in Ribeira and Lamberto than in Flamengo and Santa Rita, where lower diversity levels were associated with higher levels of metal contamination. In the present more extensive study, considering the whole molluscan assemblages throughout the year, the same diversity pattern was observed, which could be associated with differences in contamination levels, such as heavy metal concentrations, as indicated by the strong correlation we found between beta diversity among assemblages from different localities and their respective differences in heavy metal concentrations.…”
