Genetic diversity among sea snakes of the genus (Elapidae, Reptilia) in the Persian Gulf and Gulf of Oman.

Sea snakes of the genus are important components of animal diversity in Iranian waters of the Persian Gulf and Gulf of Oman. Ten species of have been identified from the these waters and, in this study, genetic structure of seven species was compared with other populations in the eastern Indian Ocean and the West Pacific. We found that six species (, , , , , and ) show high genetic similarity with conspecific populations in the Indian Ocean and Australia.

Impact of abiotic factors and road networks on the freshwater turtle Emys orbicularis (Linnaeus, 1758) (Reptilia: Emydidae) in northern Iran.

Emys orbicularis is one of the freshwater turtles occurring in Europe, Middle East and Western Asia, but also occur in Caucasus region as Georgia, Armenia, Azerbaijan and Southern Caspian Sea region (northern Iran provinces as Guilan, Mazandaran, Golestan). In this study, seventeen localities in three Iranian provinces were investigated to study the response of this species to abiotic factors (water quality parameters) and road mortality. To test for differences in occurrence of E.

Impact of pollutants on fish collected from different parts of Shatt Al-Arab River: a histopathological study.

In this study, a total of 120 fish specimens of common carp (Cyprinus carpio), were caught at four different stations in Shatt Al-Arab (Hareer, Garmat Ali, Al-Maqal and Abual-Khasib). The histological changes in the gills of fish were detected microscopically. Results show that the Shatt Al-Arab is polluted by some different sources of pollutants including power stations, paper industry, oil refineries, petrochemical industry, chemical fertilizer companies and the sewage system and overfishing and the application of pesticides.
