Other claims from this paper (14)

Observation Bidens pilosa var. radiata attracted greater pollinator diversity than the two more self-compatible Bidens taxa.
Observation Bidens pilosa var. radiata attracted greater pollinator abundance than the two more self-compatible Bidens taxa.
Observation BH floral volatiles contained 37 VOCs.
Observation DL floral volatiles contained 33 VOCs.
Observation SY floral volatiles contained 34 VOCs.
Observation Eleven floral volatile compounds differed significantly among the three Bidens species.
Observation The (E)-β-Ocimene proportion in BH floral volatiles was 18.31 ± 1.10%.
Observation The (Z)-β-Ocimene proportion in BH floral volatiles was 33.93 ± 3.49%.
Observation Combined ocimene content in BH was 52.24 ± 4.59%, significantly above DL at 1.72 ± 0.50%.
Observation Combined ocimene content in BH was significantly above SY at 0.32 ± 0.19%.
Intervention effect (E)-β-Ocimene significantly attracted A. cerana in Y-tube assays.
Intervention effect (Z)-β-Ocimene significantly attracted A. cerana in Y-tube assays.
Mechanism The authors suggest the two ocimene isomers contribute to BH attractiveness to local pollinators.
Association The authors infer stronger self-pollination ability reduces pollinator-attracting VOC content within Bidens.
