Resting cyst and motile thecate cell stages of three heterotrophic Protoperidinium oblongum, Protoperidinium sp and Protoperidinium claudicans were assessed. Cysts were isolated from sediment collected from southeast coast of Iran. Individual live cysts were incubated under optimal conditions for germination. Results showed that Protoperidinium oblongum cysts were pentagonal smooth walled and t...

background : female sand flies of subgenus adlerius are considered as probable vectors of visceral leishmaniasis in iran. the objective of this study was to determine the morphological and genotypic variations in the populations of this subgenus in the country. methods : sand flies collected using sticky traps from 17 provinces during 2008–2010. the morphometric measurements were conducted with...

the “kuh-e-gorm” non-hunting area is located in the northwest of jahrom city, fars province, iran. since there is no adequate knowledge on fauna of this region, a survey was conducted on the vertebrate fauna of the region from april 2007 to april 2008. in total, 124 vertebrate species were identified including: 11 fishes (belong to 10 genera, four families and three orders), four amphibians (be...

Soil salinity is one of the important factors which can influence the growth anddistribution of plant species. Saline and alkaline rangelands of Golestan Province, Iran withlow-deep underground water level are considered as a halophyte plant species growing area.Attempts have been made to determine soil salinity and its relationship with Frankenia hirsutaL. In order to determine the Electrical ...
