Climate change and anthropogenic drivers are widely considered as the most important threat to biodiversity. Pollinators play an important role in ecosystem regulation. Phenological mistmatches between plant-pollinator interactions can threat at population or species level depend on the degree of specialization. Taken into account, these adverse effect and limited time for conservation, providing maps of species distribution are required to identify where vulnerable species are at risk of decline or even extinction specially for plants depend on pollinators for reproduction . Salvia, the largest genus in Lamiaceae, includes approximately 1000 species in the world with around 200 species in southwestern Asia distribution. More than 80 percent of the species are characterized by special pollination system known as lever mechanism. Salvia species in southwest of Asia are melittophilous, pollinated by insects, mostly bees. (Apis mellifera, Bombus sp and Xyclocopa sp). Iran with 72 species of Salvia in which 19 of them are endemic is one of the main center of Salvia diversity in southwestern Asia,we focused on Iranain Salvia and relevant pollinators to realize how the ongoing climate change can effect on Salvia distribution in future using ecological niche modeling. We used the current and the future models to realize whether the niche shift in plants and pollinators are at the same rate in 4 stamen type of Iranian Salvia. Our analysis showed that Salvia species with smaller floral size (4-9 mm) in lower latitude reduce their suitable area in future more than Salvia with larger flowers. Also small flowers have lower niche overlap with their relevant pollinators. We also integrated molecular data with ecological information in aspect of phylogenetic diversity, which shows those species in lower latitudes have higher phylogenetic diversity.
