(tumbleweed) has been identified as one of the well-known and widely distributed plants with various applications in some of asian and north african countries. it belongs to the (asteraceae) family and grows in the middle east particularly in the temperate, mountainous and semi desert areas of countries such as iran, iraq, turkey, jordan, syria, eg...

The Euphrates Plain (EP) experiences large interannual variability in vegetation cover, especially in areas of marginal rain-fed agriculture. Vegetation in this region is primarily limited by available soil moisture, as determined by winter precipitation, spring precipitation, and air temperature. Satellite analyses indicate that the springtime normalized difference vegetation index (NDVI) is n...

Spatial pattern of trees can possibly indicate stand history, population dynamics, and species competition. This research was investigated in the Chahartagh forest reserve, Ardal region, chaharmehal and Bakhtiari Province, Central Zagros forest, and southwest Iranian state. In this study 53 hectare of the study area was selected and perfect inventory.  Information includes the position and kind...

This study describes morphological diversity and relationship of 14 cultivars and 133 wild fig accessions from central Zagros Mountains located in the west of Iran, based on 58 morphological characters. Among all characters, secondary drooping branches, number of bark tubers, shape of central lobe, length of central lobe/length of lamina, little lateral lobes, shape of leaf without lobed, fruit...

fauna of the the aphid parasitoids at southern parts of the zagros submountains, and their host associations have been investigated. a total of 24 parasitoid species were identified in association with 30 aphids on 36 host plant species, representing more than 80 tritrophic associations (parasitoid-aphid-plant). aphidius avenae haliday is newly reported from iran. generally, the area of souther...
