Other claims from this paper (10)
- Association Seed production was limited by pollination success over the 3 years of the pollination experiment.
- Association Seed production decreased when flowering occurred prior to bee emergence.
- Association Similar trends were detected for modified flowering phenology produced by snow removal.
- Association Following snowmelt, the length of the pre-flowering period decreased as ambient surface temperature rose, from 4 days above 7°C to 26 days at 2.5°C.
- Association Flowering onset was explained by an accumulated surface degree-day model.
- Association Bumblebees emerged when soil temperature reached 6°C.
- Association Bumblebee emergence was predictable by an accumulated soil degree-day model.
- Association Foraging activity of bumblebees after emergence might depend on air temperature.
- Association Phenological mismatch tends to occur when snow melts early but subsequent soil warming progresses slowly.
- Association Modification of the snowmelt regime could be a major driver disturbing spring phenology in northern ecosystems.
