Floral adaptation and modular trait evolution associated with a shift from bee to hummingbird pollination

open access: yesPlant Biology, EarlyView.
By comparing floral trait variation, integration and modularity in two sister species of Neotropical Costus with a pollination shift, we show that, despite pollination syndrome divergence, both species exhibit low floral variation and functional modularity, consistent with pollinator‐driven selection on traits mediating pollen transfer efficiency and ...
