abstract = {Relatively few species have been able to colonize extremely cold alpine environments. We investigate the role played by the cushion life form in the evolution of climatic niches in the plant genus Androsace s.l., which spreads across the mountain ranges of the Northern Hemisphere. Using robust methods that account for phylogenetic uncertainty, intraspecific variability of climatic requirements and different scenarios of life history evolution, we show that climatic niches of Androsace exhibit low phylogenetic signal and that they rather evolved recently and punctually. Models of habitat selection fitted onto phylogenies show that cushions provided the opportunity to occupy cold environments, thus contributing to rapid climatic niche diversification. Our results indicate that climatic niches can be extremely labile, and that considering the evolution of biological traits can reveal important insights into the drivers of climatic niche evolution.}
