Nova hipótese de relacionamento filogenético entre os gêneros de Euglossini e entre as espécies de Eulaema Lepeletier, 1841 (Hymenoptera: Apidae: Euglossini) New hypothesis of phylogenetic relationships for the genera of Euglossini, and for the species of Eulaema Lepeletier, 1841 (Hymenoptera: Apidae: Euglossini) [PDF]
Acta Amazonica, 2006 O gênero Eulaema Lepeletier, 1841, assim como os demais gêneros de Euglossini, é particularmente conhecido por suas relações com as orquídeas. É exclusivamente neotropical, composto de abelhas grandes (20 a 30 mm), com pilosidade densa, língua longa e ...

Gynandromorphy in Eulaema atleticana Nemésio (Apidae, Euglossini)
EntomoBrasilis, 2012 A gynandromorph specimen of Eulaema atleticana Nemésio, the first registered in Eulaema, is described. The E. atleticana gynandromorph was captured using an eucalyptol scent trap, in the Mata do Buraquinho Reserve, an Atlantic Forest fragment.

Different Physiognomies and the Structure of Euglossini bee (Hymenoptera: Apidae) Communities
Sociobiology, 2018 Our aim was to evaluate the occurrence of orchid bees in remnants of the Atlantic Forest. We sampled specimens from five regions of Southeast Brazil, covering three different physiognomies of the Atlantic Forest (mixed Araucaria forests with high ...

Diversity and distribution of orchid bees (Hymenoptera: Apidae, Euglossini) in Belize. [PDF]
PeerJ, 2023 Background Orchid bees are abundant and widespread in the Neotropics, where males are important pollinators of orchids they visit to collect fragrant chemicals later used to court females. Assemblages of orchid bees have been intensively surveyed in parts of Central America, but less so in Belize, where we ...

Interaction between floral rewards and floral symmetry shapes diversification dynamics in Amazonian trees. [PDF]
New PhytolSummary Floral zygomorphy, or monosymmetry, is thought to have a positive effect on the diversification rates of angiosperms, but its true impact is still an open topic. Given the controversy surrounding this matter, our study evaluates whether rewards such as nectar and pollen produced by floral structures evolve in correlation with floral symmetry ...

Bee Body Size and Foraging Behavior Predict the Pollination Role of Bees in a Buzz-Pollinated Plant Community. [PDF]
Ecol EvolWe investigated how bee traits influence pollination success in a buzz‐pollinated plant community. Larger body size and floral sonication strongly predicted stigma contact, a proxy for pollination efficiency, while longer handling times were associated with reduced effectiveness.

Brazilian Journal of Animal and Environmental Research, 2021 Introducción. Las abejas euglossinas son consideradas indicadoras de calidad de hábitat debido a su sensibilidad a los cambios ambientales, este grupo es fundamental para mantener la estabilidad de los ecosistemas debido a su función polinizadora. Sin embargo, los procesos de deforestación están afectando negativamente a sus poblaciones.
