“…The families that showed the highest richness of pollen types were Fabaceae (7), Myrtaceae (3), Solanaceae (3), Arecaceae (2), Asteraceae (2), Euphorbiaceae (2), Melastomataceae/Combretaceae (2), Rubiaceae (2), and Sapindaceae (2). The variability between the samples of pollen comprised 82.7% on the two first axis in the Principal Component Analysis (PCA) (Figure 2).…”

“…M. capixaba (popularly known as uruçu-preta or uruçu-capixaba) is endemic to the Atlantic Rainforest where it is restricted to the mountainous area of Espírito Santo State in the municipalities of Domingos Martins, Conceição do Castelo, Venda Nova do Imigrante, Alfredo Chaves, and Afonso Cláudio embracing Pedra Azul State Park, which is protected by the government. M. capixaba was described by Moure and Camargo [2] who referred it to the Meliponini group of the Amazon region and designated by Rocha and Pompolo [3] to the same karyotype group of M. scutellaris Latreille. Experiments proved that the lack of anatomical or behavioural isolation mechanisms allowed the crossing of these species when they were brought into the same area.…”

Pollen samples were collected in three different periods from 11 Melipona capixaba Moure & Camargo hives and analyzed with melissopalynological methodology. A total of 33 pollen types were identified, of which 23 genera and 15 families were identified. The following families showed the highest pollen richness: Fabaceae (7), Myrtaceae (3), Solanaceae (3), Arecaceae (2), Asteraceae (2), Euphorbiaceae (2), Melastomataceae/Combretaceae (2), Rubiaceae (2), and Sapindaceae (2). The most frequent pollen types (>45%) were Eucalyptus, which generated great similarities between the samples, except one in which the Tibouchina was predominant. Although the majority of the pollen types showed low percentage values, the results demonstrated that M. capixaba has taken advantage of the polliniferous sources available in the Atlantic Rainforest as well as in the "Capoeira" (brushwood, secondary forest) and "ruderal" (field) plants, probably implying its importance as a pollinator of the native flora and of the exotic species.

“…This bee is endemic to the highlands of the southwest region of Espírito Santo, Brazil. Its known distribution is restricted to areas between 900 and 1000 m in elevation of the Atlantic Forest biome (Moure & Camargo 1994;Melo 1996). In this scenario, it is relevant to evaluate differences on modeled potential distribution with and without constrains on species dispersal.…”

“…capixaba lives in eusocial colonies constructed in hollow trees. Workers measure approximately 10.8 mm in length and have a predominantly dark-brown color (Moure & Camargo 1994). Most known nests of M. capixaba are in beehives that were cut and moved from the original tree branches by local residents or built of crude boxes for beekeeping.…”

Mountain endemic species are usually related to a restricted set of ecological conditions, presenting a fragmented range interspersed by lowland that may prevent its dispersion and favors isolation and speciation. 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.

“…Morphological characteristics such as the presence of yellow markings on the clipeus and inferior paraoculars and the structure of the genitalia are practically identical in the two species (Moure and Camargo, 1994). Rocha and Pompolo (1995) placed M. capixaba and M. scutellaris in the same karyotype group, characterized by a high heterochromatic content and euchromatin that is restricted to the extremities.…”

Evidence of hybridization between two species of Melipona bees

This report describes a case of hybridization between two species of Meliponinae bees (Melipona scutellaris from the Diamantina plateau in the State of Bahia, and Melipona capixaba from around Domingos Martins, in the State of Espírito Santo, Brazil). To demonstrate hybridization, electrophoretic profiles of esterase activity from three colonies were studied. Ten adult workers of M. scutellaris, M. capixaba and the hybrid colony were collected and processed individually. The pattern of esterase activity was constant for each species but differed between them, whereas hybrid bees had a pattern derived from both species. The fact that two ecologically different species of stingless bees separated by more than 300 km could still cross when placed in the same area suggests that there has not been any pressure to develop reproductive isolation.
