iran is one of the most important centers of diversity for onobrychismill. genus. onobrychis species collected from different habitates of kermanshah province during 2010-2012 were evaluated and the relationship among their eco-geographical distribution, geographical and ecological characteristics was analyzed using arcgis.  the results showed that most of the species of onobrychis grow in the ...

introduction hymenocrater from lamiaceae family is a perennial bush with 24 species in the world and 10 different species in natural habitats of iran (satil et al., 2007). hymenocrater platystegius rech. is exclusive to khorasan province in the north east of iran (mozaffarian, 1996). according to available information, %5 of plant species of iran are becoming extinct, which is 550 times higher ...

development of a green belt with suitable plant species around the source of emission can mitigate the atmospheric contamination. selection of such plant species are required to combat air pollution based on their tolerance level. present study was undertaken to evaluate the tolerance level of higher plants in east of esfahan city, iran, during 2011 in terms of assessing air pollution tolerance...

To fuel their activities and rear their offspring, foraging bees must obtain a sufficient quality and quantity of nutritional resources from a diverse plant community. Pollen is the primary source of proteins and lipids for bees, and the concentrations of these nutrients in pollen can vary widely among host-plant species. Therefore we hypothesized that foraging decisions of bumble bees are driv...

Soil microbes play key roles in ecosystems, yet the impact of their diversity on plant communities is still poorly understood. Here we demonstrate that the diversity of belowground plant-associated soil fungi promotes plant productivity and plant coexistence. Using additive partitioning of biodiversity effects developed in plant biodiversity studies, we demonstrate that this positive relationsh...

this study included 81 samples which belonged to 13 speices from myriophyllum genus. both nrdna its1 and its2 and cpdna matk, rbcl and trnh-psba loci were used for diagnose of invasive from native plant. the nrdna its1and its2 data proved highly variable and could differentiate between all but had low pcr amplification success,based on these result they would not recommend as a suitable barcode...

A field survey of wild medicinal and industrial plant species in saline habitats in the area extended along 75 km in the Jordan Valley was carried out during 2010. Results showed occurrence of 263 species of 59 62 plant families in the region. The highest numbers were belonging to Compositae (48 species), Gramineae (18 species) and Chenopodiaceae (15 species). Species were different in densitie...
