Temporal variation in the Reproductive Ecology of Veronicastrum virginicum.

This study looked at the potential impact of temporal variation in morphology and pollination systems on the reproductive success of Veronicastrum virginicum. Morphology measurements from 2015, 2016 and 2018 were compared. Pollination systems were calculated from observation and pollen load data for years 2013-16 and 2018. Hand pollination treatments were used to measure pollen limitation. Our results show a statistical difference in corolla span, stigma length, stamen length, ovary width, and height. The primary pollinator shifted from Bombus (94.69% pollen flow) in 2013 to Apis (81.3% pollen flow) in 2018. V. virginicum is not currently experiencing pollen limitation in 2018.
