Quantitative tools particularly adapted for the marine biologistWhile there are numerous texts released on quantitative tools and lots of texts that disguise quantitative terrestrial ecology, this article fills the necessity for the unique quantitative difficulties confronting marine biologists and organic oceanographers.

TABLE 2. 16S rDNA length heterogeneity analysis for Great Salt Lake North Arm aqueous extracts. 4. , 1996). A large BAC/fosmid library with 2,000 Mbp of cloned DNA was constructed from the extracted DNA. 2% of species present. , unpublished). A large-scale sequence analysis of the clones is currently underway. These preliminary results indicate that many novel species of Bacteria and Archaea are present in Great Salt Lake and are accessible using modern molecular and genomic approaches. 4. Great Salt Lake Halophiles in Education Great Salt Lake is unique and compelling.
The halophiles are no less diverse at the level of their physiology, biochemistry, molecular biology, and genetics. An aspect that is little known, even to many scientists who study life at high salt concentrations, is the surprising morphological diversity displayed by these halophiles in their natural environments. Only relatively few have spent time examining water or sediment samples from hypersaline environments in the microscope. This is to be regretted, as high-salt habitats are among the most gratifying objects for microscopic examination (Javor, 1989; Oren, 2002).
The Saltern Environment The first evaporation ponds of multi-pond salterns have salinities close to that of the seawater used as the raw material for the production of salt. These ponds are typically inhabited by macroalgae as well as by a varied community of photosynthetic microorganisms including benthic cyanobacteria and diatoms, as well as by different 44 AHARON OREN kinds of protozoa, types of marine bacteria, as well as some higher organisms: macroalgae, crustaceans, and some other higher animals (Javor, 1989).
