Abstract:Adaptation to siliceous versus carbonate substrates is thought to be an important driver of speciation in the alpine flora. The role of the pollination system in formation and maintenance of such species is presently unclear. Here, we chose three species pairs in the genera Gentiana, Primula, and Rhododendron which often occur in geographic proximity or even sympatry, to study the existence of pollination barriers in these lineages. Using remote camera and direct observation approaches, scent and color analyse… Show more
