Diversity of western hemisphere Justicia (Acanthaceae) animal pollinator groups.

Animal pollinators are critical players in angiosperm reproduction and angiosperm diversity. Flowers can adapt to their animal pollinators to attract them, leading to evolutionary transitions in floral form and color. The genus Justicia (Acanthaceae) has diverse flower shapes, sizes, and colors and is pollinated by bees, hummingbirds, butterflies, moths, flies, and bats. Previous studies have found that flower and pollen morphology correlate with pollinator groups in some Justicia clades. Still, the extent and patterns of association that animal pollinator groups have with Justicia have not been tested across the western hemisphere clade. To assess patterns in pollinator association, we created a database of animals observed visiting open flowers of western hemisphere Justicia species. The plant-pollinator interaction data used for this study’s analyses will come from observations that have been recorded in journals, floras, species descriptions, theses and dissertations, herbarium labels, online databases, and fieldwork. An iNaturalist project will be created to collect images of Justicia plant-pollinator interactions that will also contribute to the project’s database. Observed pollinators will be mapped onto a phylogeny of the clade. Transition rates will be estimated between pollinator groups, and groups will then be tested for correlations between corolla color, phylogeny, and habitat of visited plant species. This study will contribute to our understanding of the patterns and processes of flower adaptations to different groups of pollinators.
