Sediment cores taken from Lake Ontario indicate the introduction of Actinocyclus normanii f. subsalsa is correlated with the extirpation of native species including S. transilvanicus, Cyclotella comta, C. michiganiana, C. ocellata, and C. stelligera.

Field
|
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.
