conodonts of khoshyeilagh formation, the most complete section of devonian rocks in the alborz mountains, northern iran, has been studied, and subspecies of the genera icriodus, bipennatus, polygnathus, pelekysgnathus, ancyrodella, palmatolepis, bispathodus, scaphignathus, clydagnathus, gnathodus, scaliognathus and dollymae have been obtained from the studied section. the faunas indicate an eif...

For the first time in more than 100 years, a new western Palaearctic species of Heloridae is described. Specimens of Helorus alborzicus Izadizadeh, van Achterberg & Talebi sp. nov. and Helorus ruficornis Förster were collected from the Alborz province of Iran. An illustrated identification key for Western Palaearctic Heloridae is provided.

According to the increased fungi contaminations and related damages, microbiologist's incentive in considering the fungal contaminations in human habitats had increased. Some of fungi cause disease through production of toxins in animals as well as humans. Since these toxins are not easily distinguishable, then it is crucial to study their characteristics. Aspergillus are among the most importa...

We describe a new species of mite from Iran--Reticulolaelaps hallidayi Joharchi, Nemati & Babaeian sp. nov. (Acari: Laelapidae). The new species was collected in a nest of Tapinoma sp. (Hymnoptera: Formicidae) in Taleghan city, Alborz Province and in soil in Khuzestan province in southwestern Iran. Reticulolaelapsfaini is reported for the first time from Iran. The genus Reticulolaelaps is redes...

the study of spatial and temporal changes in climate parameters, is one the most important issues in the world's climate research. study of changes in cloud cover as one of the most important climate parameters is important, because clouds are in top of hydrologic cycle and changes in them make changes in spatial and temporal variations in other climate parameters. in this study, the spati...

This paper presents structural evidence of extensional activity in Central Alborz during Mesozoic. The structural evidence of homogenous early stage stretching such as layer-parallel to oblique boudinage of Permian and Triassic rocks in various portions of the study area accompanied by extensional-fibrous fractures were followed with more advanced extensional features. These extensional structu...
