High Arctic plants show independent responses to pollination and experimental warming
Arctic plants will experience both higher temperatures and changes to their pollination regime under future climate change scenarios. However, reproductive responses to pollination, warming, and a pollination–warming interaction likely vary with seasonal timing in phenology, and may be more pronounc...
