Here we investigate the pattern of distribution of Melipona capixaba, an endemic bee species of mountain areas of central Atlantic forest by means of species distribution modeling procedures. We aimed to describe the potential distribution of this species considering broad climatic variables and evaluate the possible non-equilibrium of its range using models that simulate restricted dispersion by inclusion of spatial variables. The models indicate that the known occurrence points are located in a small fraction of its potential distribution, which is fragmented in different mountain ridges. Models without spatial variables predicted a larger range and an overlap with the distribution of a closely related species, M. scutellaris. Ensemble models also indicate areas to future search for new population of this species, as well as important areas for its conservation.

The aim was to find out the sources used as a trophic resource by this species. The dominant pollen grains in the spectrum of the samples belonged to the families Myrtaceae and Melastomataceae. Eucalyptus was the most frequent pollen type in the corbiculae in Conceição do Castelo municipality; Eucalyptus, Myrcia, and Melastomatacea/Combretaceae in the Fazenda do Estado district; and Eucalyptus and Myrcia in the São Paulo de Aracê district, both in the Domingos Martins municipality. Eucalyptus and Melastomataceae/Combretaceae were the predominant pollen types in the food pots. Eucalyptus was the most prevalent type all year round or most of the year. The most common pollen types in the months that Eucalyptus was not present or dominant in the samples were of remaining native forest species, "ruderal" (field) plants, fruit-bearing plants, and introduced ornamental plants.
