Feeding habits of Caspian marine shad Alosa braschnikowii (Borodin, 1904), inhabiting in the western part of Caspian Sea such as prey spectrum and seasonal dynamics have been studied. As in other parts of Caspian Sea, throughout the year, the main hunt of Caspian marine shad constituted kilkas, gobies and shrimps while other groups of zoobenthos were represented in a lesser extent. Importance o...

Caspian Sea is the largest land locked water body in the world and has been characterized by significant relative sea-level changes since the Pliocene. The sea-level oscillations have strongly impacted the coastal areas depending on geomorphological setting. This study aims to investigate the impacts of sea level oscillations on low-lying coasts of the southeastern flank of the Caspian Sea...

The histopathological effects of Linear Alkylbenzene Sulfonate on the gill, liver and kidney tissues of the Caspian kutum, Rutilus frisii kutum were studied. The fish were exposed to three sublethal concentrations of anionic detergent, Linear Alkylbenzene Sulfonate (LAS) for short term intervals (192 h). Gill, liver and kidney samples were collected after 192 h of exposure to LAS and lesions we...

A total of 48 female spirlins Alburnoides sp. from the Kesselian stream (South Caspian Sea basin, northern Iran) were examined during a period from July 2008 to June 2009 to obtain data on fecundity, and to determine the spawning season of this carp. The mean absolute fecundity of females spirlin was 1722.92 (653.88) eggs. The fecundity has positive correlation with the size of the female. The...

The interaction between sea and atmosphere has profound effects on the regions climate. Meanwhile, the sea surface temperature is considered as one of the most effective components of water bodies, and the controller of many atmospheric behaviors. Because of the importance of sea surface temperatures effects on atmospheric elements and also given the role of global warming on land and sea surfa...

In this study, the ability of a regional climate model, based on MM5, to simulate the climate of the Middle East at the beginning of the twenty-first century is assessed. The model is then used to simulate the changes due to global warming over the twenty-first century. The regional climate model displays a negative bias in temperature throughout the year and over most of the domain. It does a ...
