POLLINATION OF DALECHAMPIA MAGNOLIIFOLIA (EUPHORBIACEAE) BY MALE EUGLOSSINE BEES
American Journal of Botany, 1989 Flowers of Dalechampia magnoliifolia in eastern Peru were pollinated primarily by male Eulaema meriana and E. cingulata, which collected fragrance from the secretory gland borne in the staminate cymule. The fragrance contains carvone oxide, benzyl acetate, limonene, α‐pinene, myrcine, β‐pinene/camphene, and carvone. Trigona cf.

Euglossine bees mediate only limited long‐distance gene flow in a tropical vine [PDF]
New Phytologist, 2016 SummaryEuglossine bees (Apidae: Euglossini) have long been hypothesized to act as long‐distance pollinators of many low‐density tropical plants. We tested this hypothesis by the analysis of gene flow and genetic structure within and among populations of the euglossine bee‐pollinated vineDalechampia scandens.Using microsatellite markers, we assessed ...

Prezygotic barriers effectively limit hybridization in a rapid evolutionary radiation. [PDF]
New PhytolSummary Hybridization is increasingly recognized as an important evolutionary process across the tree of life. In many clades, phylogenomic approaches have permitted unparalleled insight into the extent and frequency of hybridization. However, we continue to lack a deep understanding of the factors that limit and shape patterns of hybridization ...

More About Euglossine Bees in Amazonian Forest Fragments
Biotropica, 1991 Male euglossine bees were captured monthly for one year in modified McPhail traps baited with cineole, methyl salicylate, and skatole. The traps were operated 90 km north of Manaus, Brazil in continuous terra firme forest and forest fragments of 1, 10, and 100 ha. Of the 16 species of euglossine bees captured, Euglossa chalybeata and Eg.
