“…2014, Lundgren et al. 2015, Rashel and Patiño 2019, present study), the risk of Prymnesium parvum overcoming biotic and abiotic barriers against bloom formation in highly saline waters warrants attention. The role that the ionic composition of the upstream reaches of estuaries may play in Texas has not been examined and would be of particular interest to clarify.…”

“…Results of an in situ study conducted in Galveston Bay (Texas, USA) indicated that P. parvum can grow and become toxic in Texas estuarine waters and suggested that the presence of resident plankton may be a limiting factor for its growth (Lundgren et al. 2015). In addition, population size—driven either by immigration (via river flow) or growth of latent resident populations—early during the bloom season may also influence whether blooms will form.…”

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.

“…Like cyanoHABs, the risk of P. parvum blooms expanding into estuaries is of particular concern. Prymnesium parvum has been detected within the tidal reach of some Texas rivers [92], and its ability to grow and become toxic in Texas estuarine waters has been demonstrated [292]. So why have blooms not occurred in Texas estuaries?…”

“…At lower salinities more typical of P. parvum's inland habitats (5 psu), sulfate can also stimulate its growth [143]. Lundgren et al [292] looked into biotic factors that may influence bloom formation in Texas estuarine waters and reported that the seasonal composition of planktonic communities may complicate P. parvum's establishment in these waters. Based on these observations, Richardson and Patiño [293] suggested that biotic and abiotic conditions in the upper reach of intertidal zones may be serving as barriers to downstream expansion.…”

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.
