AIM There is little information about the prevalence of Corynosoma caspicum in fish particularly Gasterosteus aculeatus in Iran and the world. The aim of the present study was to find out the prevalence of acanthocephalan infection in Babolsar district, southern coastal of Caspian Sea, Northern Iran. MATERIALS AND METHODS Between September 2012 and August 2014, a total of 360 G. aculeatus fis...

The geographical distribution and ecological preferences of Haemaphysalis in domestic animals in Iran were studied 4 times a year from April 2003 to March 2005. A total of 1,622 ixodid tick specimens were collected from 3 different zones. Among them, 108 (6.7%) Haemaphysalis ticks, consisting of 6 species, were identified; H. punctata (3.4%), H. parva (0.5%), H. sulcata (0.6%), H. choldokovskyi...

The Gilaki and Mazandarani occupy the South Caspian region of Iran and speak languages belonging to the North-Western branch of Iranian languages . It has been suggested that their ancestors came from the Caucasus region, perhaps displacing an earlier group in the South Caspian . Linguistic evidence supports this scenario, in that the Gilaki and Mazandarani languages (but not other Iranian lang...

Information on ice cover extent over seas is crucial for ship navigation. Ice cover can also show interannual fluctuations and reflects climate variations. Ability of satellites to provide global observations at high temporal frequency has made them the primary tool for the ice cover monitoring. This study is a part of GOES-R Cryosphere application group effort to develop new, and improve exist...

[1] Rafting is one of the important deformation mechanisms of sea ice. This process is widespread in the north Caspian Sea, where multiple rafting produces thick sea ice features, which are a hazard to offshore operations. Here we present a one‐dimensional, thermal consolidation model for rafted sea ice. We consider the consolidation between the layers of both a two‐layer and a three‐layer sect...

In this study, we investigate the sources of moisture (and moisture for precipitation) over the Danube River Basin (DRB) by means of a Lagrangian approach using the FLEXPART V9.0 particle dispersion model together with ERA-Interim reanalysis data to track changes in atmospheric moisture over 10-day trajectories. This approach computes the budget of evaporation-minus-precipitation by calculating...

High dietary nitrate and nitrite intake may increase the risk of gastro-intestinal cancers due to the In vivo formation of carcinogenic chemicals known as N-nitroso compounds. In this study nitrate and nitrite residues in smoked Caspian kutum, Rutilus frisii kutum and mullet, liza auratus in the local markets (considered as batch no. 1, 2 and 3) of north of Iran were determined using Spectropho...

This paper presents a typo-technological analysis of the lithic assemblage from excavation Mesolithic site Altappeh (southeast Caspian Sea). The was excavated by C. McBurney and archaeological materials were divided between University Cambridge National Museum Iran. research is based on chipped stones stored in assemblage, consisting mostly flake tools including various scrapers notchdenticulat...
