abstract in this study, evaluation of swap model in simulating crop yield, water and salt movement in soil were investigated in the wheat- fodder maize cultivated units. the research was conducted in the voshmgir network, golestan province. the crop yield, soil humidity and moisture data in different times of agriculture year of 2007-2008 were measured. the measured and simulated data were anal...

Extreme or seasonal climatic events can lead to abrupt changes in environmental conditions. These events can produce a range of organismal responses that may help to protect local-scale populations against changes in climate. Empirical studies examining intraspecific variation in reproductive and physiological responses to varying durations of environmental stress are rare. We performed laborat...

The urban heat island effect is linked to the built environment and threatens human health during extreme heat events. In this study, we analyzed whether characteristic land uses within an urban area are associated with higher or lower surface temperatures, and whether concentrations of ―hot‖ land uses exacerbate this relationship. Zonal statistics on a thermal remote sensing image for the City...

A new species of naked amoeba, Platyamoeba pseudovannellida n.sp., is described on the basis of light microscopic and fine structural features. The amoeba was isolated from the Salton Sea, California, from water at a salinity of ca. 44%. Locomotive amoebae occasionally had a spatulate outline and floating cells had radiating pseudopodia, sometimes with pointed tips. Both these features are remi...
