Abstract

This article investigates the responses of benthic foraminiferal communities to varying copper (Cu) concentrations using environmental RNA (eRNA) metabarcoding under controlled laboratory conditions. The study found that high Cu levels reduced the abundance of living benthic foraminifera and decreased interspecific interactions but did not cause test deformities. Sensitivity to Cu varied among genera, with Glandulina, Pyrgo, Quinqueloculina, Sorites, and Vellaria showing sensitivity, while Ammonia, Operculina, Reophax, Bolivina, Glabratella, Miliammina, and Parasorites exhibited tolerance. These findings highlight the potential of eRNA metabarcoding to assess the ecological impact of heavy metal pollution and support the use of benthic foraminifera as bioindicators for monitoring marine ecosystem quality.
