Larvae of the alkali fly Ephydra hians, from Mono Lake (California), were exposed to osmotic concentrations ranging from distilled water to over 6000 mOsm of either alkaline Mono Lake water, or non-alkaline sea water/sodium chloride solutions. Larvae were capable of both hyperand hypo-osmotic regulation of haemolymph osmolality (at around 300mOsm) in Mono Lake water, but this ability was less e...

Solubility and bioavailability of heavy metals are important with respect to theirtoxicity. The discharge of municipal wastewater in soil and surface waters can affectbioavailability and mobility of heavy metals in soils and sediments. The effect of dischargeof Arak municipal wastewater on the KNO3 and DTPA extractable heavy metals in a salinesoil sampled from Mighan playa (Iran) compared to a ...

Based on Finnish lakes, meromixis is viewed from a paleolimnological perspective as a part of lake evolution. The study concludes that theoretical search of meromictic lakes is almost impossible, due to inconsistent and insufficient basic data and the complexity of meromixis as a phenomenon. An estimation of possible Finnish meromictic lakes turned out to be a few dozen. Meromictic lakes are mo...

Abstraet--Zeolites having the structures of phillipsite, merlinoite, and gobbinsite were synthesized from clear solutions at 80~ in the system Na20-K20-Ai203-SiO2-H20 and their morphologies, cell parameters, and compositions determined. At 3.5 M silica concentration, the formation of merlinoite (synthetic zeolite W) is favored over the formation of phillipsite (synthetic zeolite ZK-19) by solut...

Fisheries in Cuitzeo, the second largest Mexican lake, used to take place on permanent freshwater East and Central Basins as opposed temporal, saline, initially thought barren West Basin. The 1980 fisheries collapse forced fishers look for non-conventional fishing products elsewhere lake. Basin’s saline-alkaline, shallow water provides exceptional habitat ephydrids flourish. Locally known “pupa...

Great Salt Lake, Utah, is a large, terminal, hypersaline lake consisting of a northern more saline arm and a southern arm that is less saline. The southern arm supports a seasonally abundant fauna of low diversity consisting of brine shrimp (Artemia franciscana), 7 species of brine flies, and multiple species of algae. Although fish cannot survive in the main body of the lake, the lake is highl...

Managing terminal lake elevation and salinity are emerging problems worldwide. We contribute to terminal lake management research by quantitatively assessing water and salt flow for Utah's Great Salt Lake. In 1959, Union Pacific Railroad constructed a rock-filled causeway across the Great Salt Lake, separating the lake into a north and south arm. Flow between the two arms was limited to two 4.6...

change detection is process of identifying differences in the state of an object or phenomenon by observing it at different times when it can play an important role in regional planning. this study is an integration of remote sensing data and geographic information system in order to detect changes of land use/land cover around the bakhtegan lake in fars province from 1956 to 2007. after geomet...

Small cyanobacteria (<2 µm, pico-cyanobacteria) are abundant in waters deeper than the oxic-anoxic zone in the halocline of a saline meromictic lake, Lake Suigetsu, Fukui, Japan. We have isolated 101 strains that were grouped into six groups by means of the phycobiliprotein composition and sequence homology of the intergenic spacer between the 16S and 23S rRNA genes. Significant growth was obse...
