Medicinal species of mountain’s kelavs, scientifically named (kelussia odoratissmia Mozaffar.) is an endemic species in Iran. Kelussia odoratissima is a perennial species and belongs to the umbelliferae. From the ancient times, the local and nomad societies had believed that the species traditionally have anti-ache, anti-inflation and anti-cough effects. Seed and root of this species are boiled...

Root-knot nematodes (RKN) are the most serious plant parasitic nematodes having a broad host range exceeding 2,000 plant species. Quercus brantii Lindl. and Q. infectoria Oliv are the most important woody species of Zagros forests in west of Iran where favors sub-Mediterranean climate. National Botanical Garden of Iran (NBGI) is scheduled to be the basic center for research and education of bot...

We studied the behavior of earthquake network using HEALPix spherical pixelization and square cells methods. In first method, geographical region is divided into isolatitude rhombic-spherical same areas method. second we equal cells. To construct a network, if an happens in cell, that cell will become node, two nodes be connected with edge for successive events. The built from Iran’s seismic da...

Abstract. The Zagros orogenic system resulted due to collision of the Arabian plate with Eurasian plate. region is characterized by ocean–continent subduction and continent–continent collision, convergence velocity shows variations from east west. Therefore, this complex tectonic stress a wide range diffuse or localized deformation between both plates. in situ GPS data are very limited sparsely...

Introduction The Islamic Republic of Iran (Figure 1) has an area of 1,648,000 km 2 and a population of 65 million people (1995 estimate). The country has arid and semiarid climates and the occurrence of rainfall is unreliable, with a coefficient of variation as high as 70%. The average annual precipitation over the country is around 250 mm. Two mountain ridges, the Alborz and Zagros (Figure 1),...

Geobotanical assessment of taxa with a high percentage of richness and endemism plays an important role on conservation plans. South-West Asia is one of the main biodiversity centers of the genus Onosma (Boraginaceae) comprising a high rate of species richness and endemism in Iran. Due to existing threatened factors to habitats and lack of sufficient data on conservation and distribution patter...
