Hutt Lagoon, 28° 11′S, 114° 15′E, 600 km north of Perth, Western Australia and lying 5 m below sea level is the site of a pilot plant erected by Roche Algal Biotechnology for growing and harvesting the alga Dunaliella salina. [] Key ResultFourteen ciliates, 10 zooflagellates and 4 sarcodines were observed frequently enough in brines of over 15% (w/v) salinity to identify. At least one parasite of D. salina is included in the flagellate group.
Isabela Crater-Lake: a Mexican insular saline lake
The Isabela Crater-Lake is a bright-green, hypersaline lake on Isabela Island off the Pacific coast of Nayarit, Mexico, which appears meromictic, with three well-defined strata separated by sharp pycnoclines.

A vast number of large lakes (≫ 100 km2) are typically very old features of the Australian landscape; they occupy areas which have changed little tectonically (e.g., they occupy ancient drainage
Seasonal change in a saline temporary lake (Fuente de Piedra, southern Spain)
The result of combined analyses for environmental variables, variables related to biological activity and the direct analysis of the planktonic community, shows the existence of two periods of dominance by autotrophs.
Flagellates from stromatolites and surrounding sediments in Shark Bay, Western Australia
The community of flagellates in Hamelin Pool was found not to be significantly different from communities from other marine benthic habitats, and abundances are also comparable to those in other sediments.

The ecology of a hypersaline ciliate, Fabrea salina was studied in two saltpans along the Mumbai coast, India. There was an apparent trend of its seasonal abundance being maximum (up to 58 x 10 3
Great Salt Lake Biology: A Terminal Lake in a Time of Change
Great Salt Lake (GSL) covers 5500 km (2100 mi) at its unimpacted elevation and is the eighth largest saline lake in the world. Its highly productive food web supports millions of migratory birds and
Microbial eukaryote life in the new hypersaline deep-sea basin Thetis
Several distinct morphotypes in brine samples suggest that the rRNA sequences detected in Thetis brine can be linked to indigenous polyextremophile protists, contradicting previous assumptions that such extremely high salt concentrations are anathema to eukaryotic life.

Salinity and the Ecology of Dunaliella from Great Salt Lake
Although this eucaryotic alga is able to grow in saturated brine better than any other alga, it is not optimally adapted to these conditions and is apparently able to maintain populations at high salinity only because it meets no competition from other algae.
Microbiology of the Great Salt Lake north arm
The Great Salt Lake, Utah, Fig. 6.1, is a fairly shallow (10m) terminal lake consisting of two arms of greatly different salinity separated by a rock fill railroad causeway. Although the causeway was

Based on aquarium studies, the potential for biomass production of algae and bacteria is much higher than actually observed in the north arm, leading to the postulation of two additional factors controlling population; the grazing of the algae by invertebrates with the excretion of compounds rich in nitrogen, and the effect of a low habitat temperature and winter cold on the bacteria, reducing their metabolic activities to nearly zero.

Limnology developed primarily through examination of open-water planktonic systems and limnologists, as a group, still display a mystifying propensity for studies of the planktonics, faunal and chemical components of saline lake ecosystems.
A Ciliate from the Dead Sea
A PIECE of flint-stone, 7 × 7 × 5 cm., was taken by Dr. T. Rayss on August 24, 1940, from the bottom of the Dead Sea near Kalliah from a depth of c. 150 cm. of water and handed to me. On the stone,

Halophily and halotolerance in cyanophytes
The classical division into stenohaline (narrow) and euryhaline (wide) adaptational types, with optima identified as oligo-, meso- and polyhaline, better reflects both organismal adaptations and the environmental conditions to which these are adjusted and is recommended as a conceptual model.
