Stingless bees (Apidae: Meliponini) at risk in western Mexico
AbstractThe current global pollinator crisis highlights the need to investigate the diversity and distribution of ecologically and socially relevant taxa such as tropical stingless bees. We analyzed the diversity and composition of stingless bee (Meliponini) communities at a regional scale in west‐central Mexico using an extensive direct search along ...

24 million years of pollination interaction between European linden flowers and bumble bees
Summary Pollination is the most common insect–plant mutualism, binding them in a co‐evolutionary framework. Historic evidence of this interaction can be partly inferred from time‐calibrated molecular phylogenies of plant and insect lineages or directly from fossils.

Working-class royalty: bees beat the caste system [PDF]
The struggle among social classes or castes is well known in humans. Here, we show that caste inequality similarly affects societies of ants, bees and wasps, where castes are morphologically distinct and workers have greatly reduced reproductive ...

Meliponini neotropicais: o gênero Partamona Schwarz, 1939 (Hymenoptera, Apidae) [PDF]
Neotropical Meliponini: the genus Partamona Schwarz, 1939 (Hymenoptera, Apidae). The systematics and biogeography of Partamona Schwarz, a Neotropical genus of stingless bees (Meliponini, Apinae, Apidae), are revised. Seventeen new species are described: P. epiphytophila sp. nov., P. subtilis sp. nov., P. nhambiquara sp. nov., P. batesi sp.

ABSTRACT The large carpenter bees of the genus Xylocopa comprise almost 400 species distributed worldwide. Their large body and ability to build nests through woodworking make them one of the most remarkable groups of bees. In the Neotropics, they comprise over 100 species occurring in tropical and subtropical environments including islands in the ...

Evolution of Phospholipase A2 in Bees and Flies
This study investigated the evolution of the PLA2 gene in bees and flies and compared the evolutionary rate between them, which denotes the toxic group and the non‐toxic group. The results showed that PLA2 was under purifying selection and that an accelerated evolution of PLA2 occurred in the toxic group when compared with the non‐toxic group ...
