Other claims from this paper (10)
- Observation Scrophularia californica showed significant pollen limitation in only 26.9% of patch/year combinations tested.
- Association Visitation by the most abundant (Apis mellifera) and most effective (Vespula pensylvanica) pollinators strongly predicted pollen limitation and capsule weights.
- Observation Response curves of pollen limitation and capsule weight to visitation were both highly nonlinear.
- Association Pollen limitation saturated more than capsule weight with increased visitation.
- Intervention effect Simulated pollinator loss predicted substantially increased pollen limitation.
- Intervention effect Simulated pollinator loss predicted reduced capsule weights.
- Mechanism The predicted changes were mostly due to lower visit numbers rather than changes in visit quality.
- Observation Visitation rates of individual pollinators varied substantially and without correlation.
- Intervention effect Simulated pollinator loss increased the spatial and temporal skew in visitation.
- Mechanism The authors conclude that multiple pollinators can provide stabilizing benefits for plant reproduction.
