Investigating Eusociality in Bees while Trusting the Uncertainty

Sociobiology, 2014
Phylogenetic hypotheses and estimates of divergence times have already been used to investigate the evolution of social behavior in all lineages of bees. The interpretation of the number of origins of eusocial behavior and the timing these events depends

Orchid bees (Hymenoptera, Apidae, Euglossini) are seasonal in Seasonal Semideciduous Forest fragments, southern Brazil

Papéis Avulsos de Zoologia, 2019
Seasonal fluctuations in the abundance of orchid bees have already been reported. The variations in population dynamics may be expected to occur in more predictable and pronounced manners in environments with a clear distinction between rainy and dry ...

Diversification and specialization of orchid bees and their orchid hosts

, 2008
Mutualisms between flowering plants and their insect pollinators have played a central role in the evolution of modern terrestrial biodiversity. Specialized plant-pollinator interactions provide unique opportunities to study co-adaptations, speciation ...

Colour reverse learning and animal personalities: the advantage of behavioural diversity assessed with agent-based simulations [PDF]

, 2012
Foraging bees use colour cues to help identify rewarding from unrewarding flowers, but as conditions change, bees may require behavioural flexibility to reverse their learnt preferences.

Interaction networks and the use of floral resources by male orchid bees (Hymenoptera: Apidae: Euglossini) in a primary rain forests of the Chocó Region (Colombia)

Revista de Biología Tropical, 2015
Orchid bees are important keystone pollinators from the Neotropics. With the aim to study the relationships between orchid bees and their nectar and aromatic host species, we made systematic samplings of males across two conservation areas in the ...

The orchid-bee fauna (Hymenoptera: Apidae) of ‘Reserva Biológica de Una’, a hotspot in the Atlantic Forest of southern Bahia, eastern Brazil

Brazilian Journal of Biology
The orchid-bee fauna of ‘Reserva Biológica de Una’ (REBIO Una), one of the largest Atlantic Forest remnants in southern Bahia, eastern Brazil, was surveyed for the first time. Baits with sixteen different scents were used to attract males of orchid bees.

Sexually deceptive pollination of the non-native Ophrys fuciflora (Orchidaceae) in Japan by the native bee Eucera nipponensis (Hymenoptera: Apidae)

European Journal of Entomology
A study on the pollination of Ophrys fuciflora (Orchidaceae), which is not a native orchid of Japan, was carried out in a botanical garden in Japan, where the flowers attracted the solitary bee, Eucera nipponensis.

The orchid-bee faunas (Hymenoptera: Apidae) of 'Parque Nacional do Monte Pascoal', 'Parque Nacional do Descobrimento' and three other Atlantic Forest remnants in southern Bahia, eastern Brazil

Brazilian Journal of Biology
The orchid-bee faunas of ‘Parque Nacional do Monte Pascoal’, ‘Parque Nacional do Descobrimento’ and three other Atlantic Forest remnants ranging from 1 to 300 ha in southern Bahia, eastern Brazil, were surveyed. Baits with seventeen different scents were
