Testing adaptive hypotheses for an evolutionarily conserved trait through slow-motion videos of pollinators

Traits conserved across evolutionary time often provide compelling examples of key adaptations for a given taxonomic group. Tetradynamy is the presence of four long stamens plus two short stamens within a flower and is conserved across most of the roughly 4000 species in the mustard family, Brassicaceae. While this differentiation in stamens is hypothesized to play a role in pollination efficiency, very little is known about the potential function of the two stamen types. The present study sheds new light on this mystery using wild radish (Raphanus raphanistrum), a widespread and well-studied tetradynamous plant. We used data collected from slow-motion videos of pollinators visiting wild radish flowers to test three non-mutually exclusive adaptive hypotheses: 1) short and long stamens are specialized for either feeding or pollinating, 2) short and long stamens are specialized for different pollinator taxa, and 3) the presence of short and long stamens increases pollinator movement and t..., , # Data from: Testing adaptive hypotheses for an evolutionarily conserved trait through slow-motion videos of pollinators

The data contained in these files was generated from close observation of slow-motion video footage by the same experimenter for each variable.
