Due to the great climatic variety and the peculiar north–south orographic distribution, Argentinean lake systems include a wide diversity of aquatic environments. The deepest lakes are situated in the Andean Patagonia and Tierra del Fuego, and range from ultraoligotrophic to oligotrophic. Patagonian Plateau lakes are shallower than Andean lakes and usually range from mesotrophic to eutrophic. A...

this research summarizes the data on benthic macro invertebrates collected from 25 points in the urmia lake wetlands during november 2008 to february 2009. the purpose of the study was to assess the effects of elevated salinity and nutrient (nitrogen and phosphorus) levels on macro invertebrate abundance and composition. a total of 32 taxa were collected, and the common taxa, including chirono...

Reviews of daily time-series mortality studies from many cities throughout the world suggest that daily mortality counts are associated with short-term changes in particulate matter (PM) air pollution. One U.S. city, however, with conspicuously weak PM-mortality associations was Salt Lake City, Utah; however, relatively robust PM-mortality associations have been observed in a neighboring metrop...

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...

halophilic bacteria grow over a wide range of salt concentrations. in this study we aimed to isolate and screen out the halophilic bacteria and to determine their activity for production of the bioactive compounds. a total of 50 water, sediments and soil samples were collected from maharlu salt lake in southern region of fars-iran and subjected for isolation of the bioactive compound producing ...

Studies on the effects of urbanization on stream ecosystems have evolved from documenting impacts to attempting to understand the driving factors responsible for stream conditions. In 1999, the U.S. Geological Survey’s National Water-Quality Assessment Program initiated a series of pilot studies to assess the effects of urbanization on physical habitat, biotic assemblages (algal, fish, inverteb...
