In recent years, water shortage is becoming one of the most serious problems in the Poyang Lake. In this paper, the long-term water balance items of the Poyang Lake have been analyzed to reveal the coupling effects of Three Gorges Dam (TGD) and droughts on the water balance of Poyang Lake. The results indicate that: (1) the water balance items of Poyang Lake vary greatly, e.g. lake precipitatio...

We describe a viable microbial community in a subglacial lake within the Grímsvötn volcanic caldera, Iceland. We used a hot water drill to penetrate the 300-m ice shelf and retrieved lake water and volcanic tephra sediments. We also acquired samples of borehole water before and after penetration to the lake, overlying glacial ice and snow, and water from a nearby subaerial geothermal lake for c...

orumieh lake due to economic, tourism, microclimate effect, agricultural activities have an important role in the northwest of iran. this lake basin area is 52700 km2 with 102 islands, as known a familiar it as known one of the protected areas, with 186 species of birds, and animals. the water of lake is very salty (240 gr in winter and 260gr in summer) and fluctuation of lake water level threa...

The organochlorine pesticides have been detected in the samples of sediment and muscle tissue of barbell (Barbus peloponnesius, Valenciennes, (1842); Barbus macedonicus, Karaman (1924), collected from the three natural lake ecosystems in the Republic of Macedonia, i.e. Lake Ohrid, Lake Prespa and Lake Dojran, in the period from 2004 to 2006. Special attention has been paid to the presence of th...

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...
