lake maharlu basin is located in a synclinal valley of the folded zagros. the frame and rugged structure of the basin is made of three units of mountainous geomorphologic, smooth levels and tectonic hole and evolved during several geological periods under the effect of interactive relations of tectonic, climatology and hydro geomorphologic processes. in this study, the researchers applied histo...

A process-oriented study was carried out in White Smoke lake, Bunger Hills, East Antarctica, a perennially ice-covered (1.8 to 2.8 m thick) epishelf (tidally-forced) lake. The lake water has a low conductivity and is relatively well mixed. Sediments are transferred from the adjacent glacier to the lake when glacier ice surrounding the sediment is sublimated at the surface and replaced by accumu...

both heliophysical and anthropogenic (wastewater) effects on zooplankton biomass and abundance of the imandra lake (the largest subarctic lake at kola peninsula, russia) were investigated during the 1990 - 2003 period. we used different indexes of solar activity (sunspot numbers and uv- radiation values) as heliophysical factors. information about uv- radiation values was derived from satellite...

The carbon isotopic ratios of organic matter in fish fossils from diatomites and other lake beds the HSPDP drill core Tugen Hills, Kenya (2.56–3.29 Ma) reflect trophic resource uses can indicate dietary habitats paleolake. This information offers insight into how communities responded to lake-level fluctuations during Plio-Pleistocene East African Rift Valley. We have compared this record with ...

This article examines lake drying and livelihood dynamics in the context of multiple stressors through a case study of the "Small Lake Chad" in the Republic of Chad. Livelihoods research in regions experiencing persistent lake water fluctuations has largely focused on the well-being and security of lakeshore dwellers. Little is known about the mechanisms through which lake drying shapes livelih...
