Introduction: The aim of this study was to evaluate the performance of water ozonation on disinfection by–product formation.Methods: Experiments were carried out on samples taken from Tajan River, Mazandaran province, Iran. Samples of the pre–filtered raw water and from the 3.5–L water tank reservoir (WT) were analyzed for UV–254 absorbance, dissolved organic carbon (DOC), HS and non–HS, chlorine residual, Simulated Distributed System Total Trihalomethanes (SDS TTHMs) and SDS halo acetic acids (SDS HAAs). The gaseous ozone concentration was varied between 1.5 and 10 g\m3.Results: The study showed that use of the ozonation treatment system resulted in significant improvement in water quality compared to the filtered raw water and the levels of DOC, moreover UV absorbing compounds, SDS TTHMs and SDS HAAs were reduced.Conclusion: Ozonation treatment system can be used instead of other disinfection systems such as chlorination which have potential of Disinfection By–Products (DBPs) formation.

Predatory birds feed mainly on small mammals. They usually swallow their prey and after digesting, the indigestible fur, bones and teeth are regurgitated as compact pellets. The investigation of pellet is an extremely valuable tool for mammalogists. In this study 351 pellets have been collected from the localities including north of khorasan, Zanjan, Yazd, Chahar Mahal va Bakhtiyari and Mazandaran Provinces, Iran. Results have revealed the most of pellets contain mainly the members of five families of rodents including Muridae, Dipodidae, Cricetidae, Sciuridae and Calomysidae, respectively. Although it is evident that dental morphology is a valuable tool to recognition the most genera, it is not enough for the specific identification in some cases such as Meriones and Microtus. Therefore, it would be essential employing additional approaches such as neontology and morphometrics geometric.

We studied 1038 bp of cytochrome b gene for social voles from three localities in Iran. The new sequences were compared with the previous published data correspond to eight species of social voles. Our results indicated that new material from west of Iran belong to the two species; M. socialis and M. irani karamani. This finding led to prove more knowledge about the Iranian vole distribution rang in Iran, and showed that west part of Iran is occupied with three social voles; M. socialis, M. qazvinensis that already have been documented, and M. irani karamani that is a new addition record for Iran.

The northwest Iran comprises parts of two major biodiversity hotspots; Irano–Anatoli and Caucasus. It is a mountainous transition realm between Caucasus forest in the north, Pontic forest of Turkey in the west and central deserts of Iranian Plateau. This study was designed to determine rodent diversity in northwest Iran. Moreover, corridor and barrier features of the region were investigated, as well. The samplings were done in different localities of northwestern Iran. In addition, all specimens of the Zoology Museum of Ferdowsi University of Mashhad (ZMFUM) attributed to the region were denoted. The study shows that the specimens belong to 18 nominal forms attributing to 5 families: Muridae (Apodemus witherbyi, Mus musculus domesticus, Mus macedonicus, Meriones persicus rossicus, M. libycus erythrourus, M. vinogradovi and M. tristrami bogdanovi), Gliridae (Dryomys nitedula pictus), Cricetidae (Microtus socialis, M. obscurus, M. qazvinensis, Chionomys nivalis trialeticus, Arvicola amphibious persicus, Ellobius lutescens lutescens, Cricetulus migratorius pulcher and Mesocricetus brandti brandti), Dipodidae (Allactaga williamsi schmidti) and Calomyscidae (Calomyscus urartensis).
