Project status update: Fitness and phenological extremes in experimental plot 2

2014-07-23 18.43.40

To examine the role flowering phenology plays in the reproduction of Echinacea angustifolia, Jennifer Ison planted experimental plot 2 (P2) in 2006 with 3961 individuals selected for extreme (early or late) flowering phenology. In 2014, we measured traits for all 2123 living plants and monitored the daily phenology of 247 flowering heads. Echinacea flowering began on July 2 in P2 and continued through August 24. Using the phenological and trait data collected this summer, we will explore how flowering phenology influences reproductive fitness and estimate the heritability of flowering time in Echinacea angustifolia.
