Nectar robbers pollinate flowers with sexual organs hidden within corollas in distylous Primula secundiflora (Primulaceae).

Nectar robbers are thought rarely to pollinate flowers, especially those with sexual organs hidden within corollas. In this study, we examined whether robbers pollinate flowers of distylous Primula secundiflora. Distylous plants have two floral morphs. Pin flowers have long styles and short stamens, and thrum flowers have short styles and long stamens. Flowers of P. secundiflora were commonly r...

Asymmetrical disassortative pollination in a distylous primrose: the complementary roles of bumblebee nectar robbers and syrphid flies

Heterostyly is a floral polymorphism characterized by reciprocal herkogamy maintained through high levels of mating between morphs, serviced by appropriate pollinators. We studied how differential efficiency and abundance of distinct pollinators affect plant female reproduction in self- and intra-morph incompatible distylous Primula secundiflora. Bumblebees and syrphid flies were found to be th...

High-throughput microsatellite marker development for the distylous herb Primula mistassinica (Primulaceae)1

UNLABELLED PREMISE OF THE STUDY Twelve microsatellite markers were developed for Primula mistassinica, a distylous, diploid arctic-alpine plant. The markers will be used to investigate the landscape genetics of a disjunct population on Isle Royale, Michigan, and the phylogeographic patterns of the species. • METHODS AND RESULTS We used Roche/454 high-throughput technology to sequence micro...

Net energetic advantage drives honey bees ( Apis mellifera L ) to nectar larceny in Vaccinium ashei

Carpenter bees (Xylocopa spp.) act as primary nectar thieves in rabbiteye blueberry (Vaccinium ashei Reade), piercing corollas laterally to imbibe nectar at basal nectaries. Honey bees (Apis mellifera L) learn to visit these perforations and thus become secondary nectar thieves. We tested the hypothesis that honey bees make this behavioral switch in response to an energetic advantage realized b...

Development of 13 microsatellite markers in the endangered Sinai primrose (Primula boveana, Primulaceae)1

UNLABELLED PREMISE OF THE STUDY We developed microsatellite markers for the endangered plant Primula boveana, the Sinai primrose, and assessed the cross-transferability of these markers to six related taxa. • METHODS AND RESULTS DNA sequences containing microsatellites were isolated from a microsatellite-enriched library. We obtained successful amplification of 13 microsatellite primer pai...
