New accelerator mass spectrometer radiocarbon ages from gastropods in shore deposits within the pluvial Lake Chewaucan basin, combined with stratigraphical and geomorphological evidence, identify an abrupt rise and fall of lake level at ca. 12 14C ka. The lake-level high is coeval with lake-level lows in the well-dated records of palaeolakes Bonneville and Lahontan, and with a period of relativ...

Total fatty acid composition of muscle lipids in some fish species (Cyprinus carpio (Işıklı Dam Lake), Tinca tinca (Işıklı Dam Lake), Scardinius erythrophthalmus (Işıklı Dam Lake), Cyprinus carpio (Karacaören Dam Lake), and Carassius carassius (Karacaören Dam Lake)) was determined by gas chromatography. Polyunsaturated fatty acids (PUFAs) of Cyprinus carpio (Işıklı Dam Lake) were found higher t...

Mono Lake is a hypersaline, alkaline lake in the Mono Basin located #at he eastern base of the Californian Sierra Nevada. Its lake-level history since 1912 has been recorded instrumentally, showing the decline of lake-surface elevations initiated by the 1941 artificial diversion of stream inflow. We have made high-resolution oxygen isotopic measurements on the total carbonate fraction of lake s...

In the present study, the cyanobacterial flora of Urmia Lake (NW Iran), one of the largest salt lakes in the world and adjacent rivers is investigated. Urmia Lake comprises different micro-organisms including cyanobacteria which have a major role in aquatic ecosystems. Cyanobacterial samples were collected in 2008–09 from Urmia Lake and its surrounding ecosystems. All samples were cultivated, i...

Taking into account the importance of Lake Sevan and Lake Sevan basin’s rivers for Armenian economy, the main goals of our investigations were the documentation of water quality and the biodiversity of invertebrates developed in Lake Sevan basin’s rivers and selected tributaries. Moderately satisfied ecological condition for the biodiversity of Lake Sevan basin’s rivers has been established, an...

The lakeside border of Phragmites reeds is under the control of many environmental factors, among which the flooding height and the degree of mechanical load by waves and washes are the most prominent. Examples from Lake Constance-Untersee show that the reed front retreats under enhanced stresses. Models are presented that describe the susceptibility of lakeside reeds to mechanical damage and t...

Assemblages of ostracodes from sediment cores illuminate lake-level history at decadal to centennial timescales during the late Holocene at Lake Tanganyika, East Africa. The ostracode-based lake-level curves for several cores resemble both each other and the only previously published lake-level record of comparable resolution for Lake Tanganyika during this interval, successfully reconstructing...
