The Similar Usage of a Common Key Resource Does Not Determine Similar Responses by Species in A Community of Oil-collecting Bees [PDF]
Sociobiology, 2017 Variations in abundance and species richness among communities are often determined by interactions between biotic and abiotic factors. However, for communities composed of species that share a common specialization (such as similar foraging adaptations)

Sleeping aggregation of an oil-collecting bee, Centris (Paracentris) xanthomelaena Moure & Castro (Hymenoptera: Apidae: Centridini) [PDF]
Sociobiology, 2018 Sleep aggregations have been registered for some species of solitary bees and wasps. In this note we describe the aggregation behaviour of Centris xanthomelaena Moure & Castro bees in their inactive periods.

Bee Life in the City: an Analysis of the Pollen Provisions of Centris (Centris) flavifrons (Centridini) in an Urban Area [PDF]
Sociobiology, 2017 Due to deforestation and fragmentation of ecosystems, the management of bee populations targeting pollination services is increasingly urgent. Because urban environments are stressful, the dietary knowledge in such areas can help to cope with this issue ...

Floral Resource Partitioning between Centris (Heterocentris) analis (Fabricius, 1804) and Centris (Heterocentris) terminata Smith, 1874 (Hymenoptera, Apidae, Centridini), in an Urban Fragment of the Atlantic Forest [PDF]
Sociobiology, 2017 The knowledge on plant species used for the collection of floral resources is crucial to understanding interactions between plants and bees. The aim of the present study was to identify floral resources used by Centris analis and Centris terminata to ...

Divergent genetic mechanisms underlie reversals to radial floral symmetry from diverse zygomorphic flowered ancestors. [PDF]
Front Plant Sci, 2013 Malpighiaceae possess flowers with a unique bilateral symmetry (zygomorphy), which is a hypothesized adaptation associated with specialization on neotropical oil bee pollinators.
