      abstract = {Plants require access to photosynthetically active  radiation (PAR), which also exposes them to potentially  damaging ultraviolet wavelengths. Anthocyanin is a  secondary compound which provides red coloration for  flowers and has been shown to absorb light in the UV  spectrum. Ipomopsis aggregata displays flower color varying  from pink to scarlet red, correlated with anthocyanin  content. In this study, we compared the UV protective  qualities of I. aggregata individuals with scarlet flowers  (dark-colored) to plants with pink flowers (light-colored)  using a combination of field observations (Manitou  Experimental Forest) and in situ experimental  manipulations. The field methodology included measurements  on photosynthetic efficiency, stomatal conductance,  anthocyanin content, chlorophyll content and leaf  temperature to attempt to understand if there were  differences among the light and dark colored morphs.  Germination rate and seed mass were also quantified. The  dark morphologies had greater anthocyanin content which  could allow them greater UV protection. Dark morphologies  also had higher photosystem efficiency, chlorophyll  content, stomatal conductance, seed mass and germination  rate. However, light morphologies may have a greater  diversity of pollinators. This could indicate a  reproductive and survivorship trade-off, connected directly  to flavonoid content, between pollinator attraction and  protection from UV damage in a mid-elevation plant  population.},
