Barley fields and storages in GolestanProvince (northeastern Iran in south bank of the Caspian Sea), surveyed in 2005 and 40 grain samples were randomly collected for identification of fungi associated with them. Fungi were isolated from these samples by agar plating, deep freezing blotter and seed washing methods. Some six hundred fungal isolates were obtained, among which 30 species belonging...

For identification of arbuscular mycorrhizal fungi (AMF), in the late springs of 2004 and 2005, wheat fields in the GolestanProvince (northeast of  Iran near the Caspian sea) surveyed and root cores sampled. After extraction of AMF spores and staining roots, 19 AMF identified as follow: Entrophospora infrequens, Glomus caledonium, G. clarum, G. constrictum, G. deserticola, G. eburneum, G. etuni...

introduction:cats carry a lot of zoonotic parasites such as toxoplasma gondii which causes toxoplasmosis in warm-blooded animals. toxoplasmosis includes wide range of symptoms in its intermediate and definitive hosts but the worst symptoms have been seen in pregnant women and also on immunocompromised hosts. considering the importance of cats as the only definitive host that spread the t. gondi...

in order to study the effects of climate and geomorphology on the development of soils and their physico-chemical peroperties, two transects on the loess parent material were selected in two regions of golestanprovince. the regions were: huttan (maraveh tappeh area) and gorgan with aridic-thermic and xeric-thermic soil moisture and temperature regimes, respectively. four pedons in hutan and fiv...

studies on vegetation changes of rangelands under grazed and non-grazedconditions are of great importance in the range management planning programs. to determinethe change process of vegetation, this study was performed in inche shorezar site of golestanprovince for nine years (1997-2005). the vegetation parameters were measured every year inseveral fixed plots inside and adjacent of exclosures...
