WebDec 17, 2024 · High salinity is a challenging environmental stress for organisms to overcome. Unicellular photosynthetic microalgae are especially vulnerable as they have to grapple not only with ionic imbalance and osmotic stress but also with the generated reactive oxygen species (ROS) interfering with photosynthesis. This review attempts to … WebSalinity is a measure of the content of salts in soil or water. Salts are highly soluble in surface and groundwater and can be transported with water movement. There are two types of salinity: Primary salinity — large salt deposits that are a natural feature of vast areas of the Australian landscape, stored deep in soils or as surface salt deposits and salt lakes.

WebJan 26, 2024 · The high salt content in hypersaline environments is a major life-limiting factor. In fact, such salt-polluted environments are commonly populated by halophilic microbes and hypersaline-tolerant microbial mats (Oren 2000). The latter mentioned groups are considered to be a self-sustaining ecosystem, which has adapted continuously to ...
At high latitudes, salinity is low. This can be attributed to lower evaporation rates and the melting of ice that dilutes seawater. To sum up, salinity is low where precipitation is greater than evaporation, mainly in coastal or equatorial regions.
