| Impact Description | Due to a high demand of silica for its heavily silicified walls, during blooms, Actinocyclus normanii fo. subsalsa may deplete dissolved silica concentration in shallow bays. The resulting silica-limited environment is detrimental to species of native diatoms that are dependent on silica availability and promotes the growth of harmful blue-green algae. |
