Other claims from this paper (9)
- Intervention effect The presence of showy B. cernua increased seed set of B. frondosa in natural populations but not in common garden experiments
- Observation Little evidence of a cost of pollinator facilitation for B. cernua
- Intervention effect Both Bidens species showed enhanced seed set from conspecific pollen supplementation
- Intervention effect Both Bidens species showed no cost of heterospecific pollen deposition
- Association B. cernua and B. frondosa co-occurred more often than expected by chance across New York State
- Association Frequent co-occurrence between radiate and discoid Bidens was general across multiple species in the genus
- Association Radiate Bidens species aggregated with discoid Bidens species more often than expected
- Observation Bidens spp. spatially disaggregate, likely due to competition
- Association Display trait contrast predicts species co-occurrence across the landscape
