Winter drought impact on the reproductive ecology of Ratibida pinnata.

Temperate plant reproductive biology can be impacted by events such as climate change. In this study, the reproductive success of a Missouri native plant, Ratibida pinnata, is determined by comparing milder winter with low precipitation and more intense summers. Pollinator observations, pollen loads and seed viability were measured to determine current main pollinators and pollination success in drought and non-drought years. We found morphological changes occur along with a shift from Bombus to Halictidae pollination in drought years. These shifts did not result in pollen limitation. Further collection is needed to determine long-term effects.
