Pollination Biology Czapla, Grant [1], Kyra, Krakos [2], Hulsey, Ryan [3]. A comparison of pollination systems of Oenothera nealleyi in pre and post drought years. Pollination systems can change in response to environmental factors. These changes may be from a generalist to a specialist pollination system, or a shift to a different main pollinator. These changes may be detrimental to the reproductive success of the species. In this study we focus on the pollination systems of O. nealleyi in pre (2009) and post (2015) drought years. We compared detailed pollination data from 2009 and 2015 in the same populations in Alpine, TX. We used hand pollination studies to determine if the species is currently experiencing pollen limitation. Our results indicated a shift from the majority of pollen flow moved by noctuid moths in 2009, to 100% of the pollen flow moved by bees in the day in 2015. However, O. nealleyi is not experiencing pollen limitation (p= 0.909) in 2015. The change in pollination systems may reflect how a species can maintain reproductive success even through climate changes.
