An examination the stability of pollination systems in shifting climate conditions using a comparison of Eastern and Western Missouri populations of Asclepias tuberosa.

Temperature, and other abiotic factors, can cause variations in floral reproductive biology that may impact the pollination systems of different habitats. In this study, we compare the morphology of Asclepias tuberosa in Eastern and Western Missouri populations. Morphological measurements from 2020 to 2021 of these populations were compared. Temperature data was collected and examined from 2020 to 2021 to understand its impact on floral morphology. Our results indicate that in warming temperatures, display size increases, though, there was no impact of display size on visitation rate. This suggests that there is a threshold for display size before pollination behaviors are affected.
