Waiting for the snow to melt…
Climate change is causing warmer temperatures and earlier snowmelt throughout the mountains of Western North America. This study was designed to investigate how these two factors of temperature and snowmelt date influence floral traits, using Ipomopsis aggregata as a model species. While phenological shifts caused by temperature and snowmelt date have been studied in depth, impacts on physical traits such as floral morphology and emitted volatile organic compounds (VOCs) are less well known. In this research, both floral morphology and VOC identity and quantity were measured over one summer to determine if manipulated temperature and date of snowmelt have any effect on these characteristics. I. aggregata individuals treated with higher temperature developed longer corollas and produced more nectar and sugar. Volatile emissions were not strongly impacted by either higher temperature or early snowmelt.
