| assessment of pollen reward and pollen availability in solanum stramoniifolium and solanum paniculatum for buzz-pollinating carpenter bees. | the two widespread tropical solanum species s. paniculatum and s. stramoniifolium are highly dependent on the visits of large bees that pollinate the flowers while buzzing them. both solanum species do not offer nectar reward; the rewarding of bees is thus solely dependent on the availability of pollen. flower visitors are unable to visually assess the amount of pollen, because the pollen is hidden in poricidal anthers. in this study we ask whether and how the amount of pollen determines the att ... | 2014 | 24138093 |
