摘要: Abstract This study aimed to investigate the potential effects of iron ore tailings from Fundao dam (southeastern Brazil) through suspended particulate matter (SPM) on copepod community in marine area adjacent Doce River mouth (DRM), and characterize related oceanographic structure 2016. Diversity was considered low very (min H ' = 0.36; max H' = 2.09) throughout period. The results showed a negative correlation between higher concentrations SPM with Temora turbinata Centropages velificatus being indicator species for this scenario. Water masses were main constituting factor where SACW responsible increase ecological indexes addition dominance stylifera Paracalanus quasimodo. rates diversity abundance recorded point chronic associated which are enhanced absence SACW.
