this thesis attempts to measure learning styles, self efficacy and intrinsic motivation as predictors of iranian ielts reading comprehension. in order to address this issue, a quantitative study was conducted on some randomly selected intact students at ferdowsi university. these two groups were assigned as they were undergraduate (ba=91) and graduate (ma =74) students; they were all aged betwe...
a survey was carried out to investigate the frequency of hard tick species (acari: ixodidae) on sheep in khorasan razvi province. a total of 812 ticks were collected from the sheep of different areas of khorsan razavi province five species were identified as follow: rhipicephalus turanicus (59.23%), hyalomma.marginatum turanicum (25.73%), hyalomma excavatum (14.8%), hyalomma anatolicum (8.3...
In this study, we report some endophytic fungi isolated from twigs of Quercus brantii in Dena region of Kohgiluyeh and Boyer-Ahmad province. The twigs were sampled from trees which had basidiocarps of the invasive basidiomycetous polypore fungus Inonotus krawtzewii on their trunk. Altogether, ca. 40 pure isolates were obtained. The ITS sequences were obtained for 16 isolates, and their phylogen...
The study of plant communities is the best way to learn about vegetation structure and distribution as well as various interactions among the plants in an ecosystem. Elevation factor plays a vital role in plant distribution that ultimately leads to specific phytogeographic regions. This study evaluated the changes in species composition, density, frequency, canopy cover and palatability of spec...
the species diversity and geographical distribution of the scorpion fauna of chaharmahal va bakhteyari province is little known so far. in the present study, more than 110 specimens were collected from near 20 sampling stations from different regions of ch & b province. in total, five species belong to five different genera were found. the species were identified as mesobuthus eupeus phillipsii...
Background and Purpose: Lipophilic yeast of the genus Malassezia are members of normal human cutaneous micro flora which are also associated with several skin diseases. It is strongly suspected that Malassezia species are responsible for pityriasis versicolor (PV), and seborrhoeic dermatitis (SD). Considering various sensitivities among Malassezia species to antifungal, accurate species identif...
Seven species of aphids belonging to the family Aphididae in six genera were collected and identified in wheat and barely fields in Sistan region (Miankangi, Shahraki-Narooi, Shibab and Markazi) during1999-2000. Among them, Schizaphis graminum (Wheat green aphid) was the dominant species with an abundance of about 85.4% in the area. The seasonal population changes of Schizaphis graminum were st...

The diversity of Trichoderma spp. was investigated in alkaline soils of pistachio orchards at different geographic areas in Kerman province, Iran. A total of 161 Trichoderma isolates were obtained and identified at the species level by their morphological characters and sequence analysis of their internal transcribed spacer (ITS) and tef1-α genomic regions. Totally, five species of Trichoderma ...
