“…Figure 4 shows an updated historical distribution of P. parvum toxic blooms or presence by state. Prymnesium parvum is highly euryhaline and found in marine, estuarine, and inlan waters worldwide [32,79]. There is some confusion in the literature regarding the distr bution of P. parvum and its blooms in the USA.…”

“…In contrast to cyanobacteria, the haptophyte lineage is predominantly marine with relatively few representatives in inland waters [31,32]. About eleven species have been recognized in U.S. inland waters [32,33], of which at least two can form harmful blooms. Prymnesium breviturrita (formerly Chrysochromulina breviturrita [32]) is a nuisance alga found in soft-water lakes in the northeastern region of the country [34].…”

Cyanobacteria are the most common toxigenic algae in inland waters. Their toxins can affect the health of aquatic and terrestrial organisms, including humans. Other algal groups, such as haptophytes (e.g., Prymnesium parvum) and euglenoids (e.g., Euglena sanguinea), can also form harmful algal blooms (HABs) whose toxins cause injury to aquatic biota but currently have no known effects on human health. Prymnesium parvum, however, is responsible for some of the worst HAB-related ecological disasters recorded in inland waters. Here, we provide an overview of the primary toxigenic algae found in U.S. inland waters: cyanobacteria (planktonic forms), P. parvum, and E. sanguinea with the objective of describing their similarities and differences in the areas of HAB ecology, algal toxins, and the potential for future range expansion of HABs. A detailed account of bloom habitats and their known associations with land cover and use is provided from the perspective of water quality. This review revealed that salinity may have an influence on inland cyanobacterial blooms and cyanotoxins that had not been fully recognized previously.

Prymnesium parvum is a euryhaline, toxin‐producing microalga. Although its abundance in inland waters and growth potential in the laboratory is reduced at high salinity (>20), the ability of inland strains to adjust their growth after long‐term residence in high salinity is uncertain. An inland strain of P. parvum maintained at salinity of 5 in modified artificial seawater medium (ASM‐5) was subjected to the following treatments over five sequential batch culture rounds: ASM‐5 (control); modified ASM at salinity of 30, raised with NaCl; modified ASM at salinity incrementally increased to 30 with NaCl; and Instant Ocean® at salinity of 30 (IO‐30). Exponential growth rate (r) was reduced when salinity was increased from 5 to 30 in ASM but returned to control values during the second round. When salinity was incrementally increased, a reduction in r still occurred when salinity reached 25‐30. Maximum density was reduced at salinity of 30 in ASM upon abrupt transfer or incremental increase, and compensation did not occur. Growth performance in IO‐30 was comparable to control values. In conclusion, (i) long‐term compensation for acute inhibitory effects of high salinity occurred for r but not maximum density, (ii) incremental increases in salinity did not prevent growth inhibition, suggesting the existence of a salinity threshold of 25–30 for onset of salinity stress, and (iii) the presence of a seawater‐like salt mixture prevented growth inhibition by high salinity. These findings provide new insights on P. parvum's long‐term ability to adjust its growth in environments of different salinity and ionic composition.
