Non-native plant invasions can change communities and ecosystems by altering the structure and composition of native vegetation. Changes in native plant communities caused by non-native plants can influence native wildlife species in diverse ways, but the outcomes and underlying mechanisms are poorly understood. Here, we review and synthesize current information for the Intermountain West of th...

Seed dispersal is critical for successful invasion and range expansion by non-native plants; dispersal is likely to be enhanced if they can successfully comp...

malaria is considered a major health problem in iran. there are different methods for vector control. in this study we tested the larvicidal effects of some iranian plants. the methanolic extracts of 11 plants were prepared with percolation method. the larvicidal activities of them against malaria vector, anopheles stephensi were studied using world health organization standard method. all lc50...

The study of compliment speech act has been under investigation on many occasions in recent years. In this study, an attempt is made to explore appraisals performed by native English speakers and Iranian EFL learners to find out how these two groups diverge or converge from each other with regard to complimenting patterns and norms. The participants of the study were 60 advanced Iranian EFL lea...

Inoculation with arbuscular mycorrhizal fungi (AMF) may improve plant performance at disturbed sites, but inoculation may also suppress root colonization by native AMF and decrease the diversity of the root-colonizing AMF community. This has been shown for the roots of directly inoculated plants, but little is known about the stability of inoculation effects, and to which degree the inoculant a...
