Tenualosa ilisha (Hamilton) is a valuable migratory fish belonging to the family Clupeidae and it is distributed in a wide area from the Persian Gulf to coasts of Pakistan and China’s southern sea. The aim of the present study was to investigate the changes occurring in innate immunity parameters during upstream migration and comparing them to those during post spawning. Sixty mature female hil...

Parts of oil spills reach Iranian coastline along the Persian Gulf in the form of tar balls and scattered oilpatches. There are many published reports regarding oil spills reaching northern coasts of the Persian Gulf,but none report on the content of heavy metals associated with petroleum in sediments and plants ofcontaminated areas. This research was conducted to determine and map petroleum- r...

Mountainous terrain exerts an important influence on the Earth’s atmosphere and affects atmospheric transport and mixing at a wide range of temporal and spatial scales. The vertical scale of this transport and mixing is determined by the height of the atmospheric boundary layer, which is therefore an important parameter in air pollution studies, weather forecasting, climate modeling, and many o...

to assess the sources, entry routes and degree of contamination of pah compounds in surface sediments of the southwestern caspian sea coasts (gillan province) total of 129 surface sediment samples from 28 rivers and 5 transect across the gillan province coasts (from astara to lahijan; 10, 20 and 50 m depth) were collected in the spring and summer of 2012. after extraction using soxhlet method, ...

Coastal evolution due to natural and human-induced causes or factors can be rather variable on quite different temporal and/or spatial scales. Our capability to understand and especially predict this variability on the longer time scales is still limited. This can lead to misinterpretation of coastal change information, which hampers informed decision-making and the subsequent functional design...
