Urmia Lake is one of the two large hypersaline lakes in the world which have Artemia. It is located in northwest of Iran. Due to a decrease in water inflow and volume, the salinity of Urmia Lake has reached to more than 300 g.l-1 since 2001. The increased salinity has greatly influenced biological aspects of the lake, and caused the lake undergoes at critical conduction. The aim of the prese...
The Utah sucker (Catostomus ardens) is endemic to the Bonneville Basin and the upper Snake River drainage in western North America, and is thought to hybridize with the federally endangered June sucker (Chasmistes liorus mictus) in Utah Lake (Bonneville Basin). Here we describe the discovery of a major subdivision in Utah suckers (4.5% mitochondrial sequence divergence) between the ancient Snak...
Cholera epidemics have a recorded history in the eastern Africa region dating to 1836. Cholera is now endemic in the Lake Victoria basin, a region with one of the poorest and fastest growing populations in the world. Analyses of precipitation, temperatures, and hydrological characteristics of selected stations in the Lake Victoria basin show that cholera epidemics are closely associated with El...
Landslides are considered to be one of the most significant natural hazards. Detection landslide-prone zones is an important phase in landslide hazard assessment and mitigation landslide-related losses. AHP as effective methods for GIS-based multi-criteria decision analysis increasingly being used susceptibility mapping. However, its weights have some degree uncertainty that interval comparison...
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...
Dating and geomorphology of shoreline features in the Qinghai Lake basin of northwestern China suggest that, contrary to previous interpretations, the lake likely did not reach levels 66–140 m above modern within the past ∼90,000 yr. Maximum highstands of ∼20–66 m above modern probably date to Marine Isotope Stage (MIS) 5. MIS 3 highstands are undated and uncertain but may have been at or below...
