Mountain colonization precedes shifts away from bee pollination in Melastomataceae. [PDF]

open access: yesNew Phytol
Summary Shifts among different groups of pollinators are central in the evolution of flowering plants, yet mechanisms underlying pollinator shifts remain unclear. Environment‐induced reduction in pollinator availability and hence efficiency may destabilize ancestral plant–pollinator interactions and trigger shifts to new, more efficient pollinators ...

Glossuropoda, novo subgênero de Euglossa, e duas espécies novas da Amazônia, do mesmo subgênero (Apidae - Hymenoptera) Glossuropoda, new subgenus of Euglossa, and two new species of Amazônia belonging the same subgenus (Apidae - Hymenoptera)

open access: yesMemorias do Instituto Oswaldo Cruz, 1989
A new subgenus Glossuropoda is proposed for Euglossa intersecta Latreille, 1837, as the type species. It is distinguished from Glossura by having a very peculiar configuration of the mid basitarsus of the male and lack of the median spur. Two new species

Raising the sugar content--orchid bees overcome the constraints of suction feeding through manipulation of nectar and pollen provisions. [PDF]

open access: yesPLoS ONE, 2014
Unlike most other bees, the long-tongued orchid bees ingest nectar using suction feeding. Although long tongues allow exploitation of flowers with deep spurs, the energy intake rate is optimal at 10-20% lower nectar sugar concentrations compared to that ...
