e0“retention of rewardless flowers in the same colour and flexibility in floral longevity – as was adopted in W . hortensis – may become more advantageous in terms of saving metabolic and ecological costs”
e1“Under conditions where benefits of enhancing both conspicuousness and exploitability cannot outweigh the costs of doing so”

Other claims from this paper (11)
- Observation W. coraeensis flowers secreted nectar for 2–3 days while white, then persisted red purple with reduced nectar.
- Observation W. hortensis flowers secreted nectar initially for 2–3 days.
- Observation W. hortensis flowers persisted with unchanged color and reduced nectar only when pollinators were scarce.
- Observation Only W. hortensis suffered pollination difficulty at the study site.
- Observation Both Weigela species retained flowers for 4–5 days.
- Observation Bees strongly preferred to visit W. coraeensis.
- Observation W. coraeensis had a greater proportion of seed set than W. hortensis.
- Observation W. coraeensis had higher nectar productivity than W. hortensis.
- Mechanism W. coraeensis alone offered bees a color cue to choose rewarding flowers and improve nectar intake rates.
- Mechanism Bees apparently learned where to return in response to resource exploitability differences.
- Mechanism The authors conclude that floral color change attracts bee-like pollinators that return to more easily exploitable plants.
