| Impact Description | Conticribra guillardii has been recorded at abundances reaching 95% of the diatom community in locations outside of the Great Lakes, although it is more typically less abundant in freshwater (Hasle 1978). In the Great Lakes, C. guillardii has only been recorded once (Sandusky Bay, OH), and the abundance of this sample compared to the rest of the phytoplankton was not recorded. |
