Increasing atmospheric anomalies have altered some of the extreme events such as global warming droughts, many climatic components such as precipitation, evapotranspiration, temporal and spatial distribution of precipitation, followed by dominoes of changes in freshwater resources available to communities. Human changes such as changes in the hydrological regime of rivers, changes in the qualit...
Lake area, water level, and storage changes of terminal lakes are vital for regional resource management understanding local hydrological processes. Nevertheless, due to the complex geographical conditions, it is difficult investigate analyze this change in ungauged regions. This study focuses on ungauged, semi-arid Gahai Lake, a typical small lake Qaidam Basin. In addition scant observed data,...
Higher quality of services provided in the rural areas requires feedback, consulting with villagers, and their active participation in rural development process. Water services are one of the most basic services provided in rural areas. Accordingly, the present study seeks to evaluate the satisfaction level of rural residents with the quality of services provided by Rural Water and Wastewater C...
Aquaporin-2 (AQP2) is responsible for the concentration of urine in the kidney collecting tubule under the regulation of vasopressin. The mRNA level of this water channel in polydipsic STR/N mice was extremely reduced compared with that in normal ICR mice. In male mice, reduction of the AQP2 mRNA level was not evident at 3 wk of age, at which time water intake was not increased. At 10 wk of age...
Mehrgerd region of Semirom county has faced the water shortage for several years. The emergence of drought has led to a decline in water resources in recent years; and there are various reasons for climate change and increased consumption in order to reduce water resources. The present study aimed to investigate the process of temperature and precipitation variations and its possible effects on...

the objectives of this work was to examine the toxicological effect and molecular changes caused by a heavy metal pollutant mercuric chloride (hgcl2), in fresh water snakehead channa punctatus, locally known as taki fish in bangladesh. when fishes were exposed to hgcl2, it induced death of the fishes in a concentration-dependent manner. 1 mm, the highest concentration tested in this study, was ...
Lake-level variations at Marcella Lake, a small, hydrologically closed lake in the southwestern Yukon Territory, document changes in effective moisture since the early Holocene. Former water levels, driven by regional palaeohydrology, were reconstructed by multiproxy analyses of sediment cores from four sites spanning shallow to deep water. Marcella Lake today is thermally stratified, being pro...
