Grazing effect on vegetation cover and soil factors in natural environments is inevitable. The present study was conducted to investigate the effect of grazing on soil factors and distribution of plant species in grazed and non-grazed areas in rangelands of western parts of Hoz-e-Soltan Lake, Qom. Systematic-randomized sampling method was used alongside of 4 transects. Adjacent to the transects...

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...
Extended abstract 1- Introduction Urmia Lake as the largest domestic lake in Iran is drying. Climate change in the northwest of Iran, rainfall reduction and evaporation, due to the increase in average temperature in the Northwest of the country accompanied with the involvement of human factors such as dam construction, have caused an irreparable environmental hazard in the northwestern of Ira...

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...
