Investigating the role of climate and geography in the evolution of pollination syndrome in Thalictrum (Ranunculaceae).

A major aspect of evolutionary biology is understanding how taxa evolve when they move to new areas, since this movement implies exposure to novel environmental and ecological regimes to which these taxa must adapt. Transitions into similar regimes may cause lineages to evolve convergent traits.†Thalictrum†(meadow-rues, Ranunculaceae; ~196 species) is a clade of flowering plants that has evolved wind pollination multiple times independently, and these transitions have been hypothesized to be correlated with major biogeographic shifts in the group. In this study, we (1) develop and present an updated phylogeny for†Thalictrum†and several closely related genera, (2) reconstruct the historical biogeography of the clade, and (3) investigate the correlation of environmental variables associated with shifts in biogeography and the evolution of wind pollination in†Thalictrum.
