Variability in biomarkers of different saline basins in China
International Journal of Salt Lake Research - Tập 6 - Trang 25-53 - 1997
42 samples (sediments and crude oils) from 5 differentsaline/hypersaline basins of China were examined using variety ofgeochemical techniques. A pronounced even over odd distribution of n-alkanesis observed for the Ejinur, Jianghan samples. Abundance of isoprenoidalkanes, dominated by phytane (C20 up to 20 per cent inEOM), and C25 and C30 components isanother outstanding feature of these studied l...... hiện toàn bộ
An overview on lagoons in the Polish coastal area of the Baltic Sea
International Journal of Salt Lake Research - Tập 6 - Trang 121-134 - 1997
Coastal lagoons in Poland arebiologically diverse and very productive areas, andhave a high economic importance as waterways, astourist resorts and through fisheries. On the otherhand, they remain under strong antrophogenic pressuredue to the high load of nutrients from agriculture,discharge of large amounts of municipal sewage andindustrial wastes. Three important Polish lagoons,namely the Odra/S...... hiện toàn bộ

Are assemblages of black bream (Acanthopagrus butcheri) in different estuaries genetically distinct?
International Journal of Salt Lake Research - Tập 6 - Trang 303-321 - 1997
Samples of the estuarine-spawning teleostAcanthopagrus butcheri were collected from nine estuaries and a coastal lake, located in the Pilbara and South-western drainage divisions of Western Australia and distributed along a coastline covering a distance of nearly 2,000 km. The patterns of allozyme variation in these samples were used to explore the extent to which there was variation in the geneti...... hiện toàn bộ
Carbon stable isotopes ratios of pelagic and littoral communities in Alchichica crater-lake, Mexico
International Journal of Salt Lake Research - Tập 7 - Trang 345-355 - 1998
Carbon stable isotope ratios were determined in dominant biotic components of pelagic and littoral systems in Alchichica crater-lake. Results showed that carbon signatures were significantly different between both systems. The pelagic environment was more depleted (−26.15 to −15.14 per mille) than the littoral zone (−21.03 to −17.91 per mille). The potential source end-point in the simplified pela...... hiện toàn bộ
Fractional crystallization of salts from subsoil brines—I
International Journal of Salt Lake Research - Tập 6 Số 4 - Trang 331-351 - 1997
Solar evaporation studies of subsoil brines from three different locations of Gujarat State in India were undertaken. Evaporation of brines from their initial densities to 29–30° Be' density was studied and the data were compared with those of sea brine. From the experimental data, the change in the quality of salts crystallized at various density levels with changing ionic composition of brines i...... hiện toàn bộ
Chemical composition of saline and subsaline lakes of the northern Great Plains, western Canada
International Journal of Salt Lake Research - Tập 1 - Trang 47-76 - 1992
The northern Great Plains of Canada stretch from the Precambrian Shield near Winnipeg, Manitoba, westward for ∼1,700 km to the Rocky Mountains foothills. This vast region of flat to gently rolling terrain contains a very large number of salt lakes. Major ion chemical data on ∼500 of them are available. Although the average brine (salinity, 37 ppt) is a Na+−SO4
2− type of wa...... hiện toàn bộ
Chlorophylla of size-fractionated phytoplankton at a temporary hypersaline lake
International Journal of Salt Lake Research - Tập 5 - Trang 253-260 - 1996
The size-fractionated distribution of chlorophylla was studied in a temporary hypersaline lake situated in the south of Spain during an annual hydrological cycle characterized by low levels of rainfall. The contribution of each size class to the total chlorophylla concentration indicates that ultraplankton (size class <5μm) was the most important fraction of phytoplankton biomass during this year.
Effect of turbulence and inorganic carbon supply on growth ofDunaliella viridis Teodoresco
International Journal of Salt Lake Research - Tập 4 - Trang 223-232 - 1995
Turbulence is known to enhance growth in microalgae. We studied the possible effects of the extra inorganic carbon supplied to the cultures when air bubbling is the source of turbulence. A set of experiments was carried out to separate the effects of the subsidiary action of agitation on growth from those due to possible carbon enrichment from air CO2 when air bubbling was the source of mixing. It...... hiện toàn bộ
Falling water-levels in saline lakes of the central Rift Valley of Kenya: The case of Lake Elmenteita
International Journal of Salt Lake Research - Tập 3 - Trang 65-74 - 1994
Reasons why Lake Elmenteita and rivers flowing into it decreased in volume during 1958–1987 were investigated. The effects of changing climate, landcover and landuse were considered. The study suggested that falling lake water-levels are not due to climate change alone: landuse changes and river abstraction and damming may also be important. Long-term trends in rainfall and evaporation reveal vari...... hiện toàn bộ
