Other claims from this paper (6)
- Observation Male flowers were more numerous and more exposed to pollinators than female flowers.
- Observation Nectar chemical composition and sugar proportions were similar between male and female flowers.
- Observation Total nectar sugar production per female flower was threefold higher than per male flower.
- Intervention effect Nectar removal did not affect total nectar production in either flower morph.
- Association Pollinators reduced standing nectar to similarly scarce amounts in both flower types.
- Association The authors infer greater pollinator nectar consumption from female flowers.
