“…Augastes scutatus and Asthenes luizae). Therefore, our records for AP support the biogeographical relationship of the Espinhaço range with particular disjunct regions in South America (Sick 1985;Vielliard 1990;Silveira and Cure 1993;Stehmann and Semir 2001;Vasconcelos et al 2006;Vasconcelos and Rodrigues 2010).…”

We surveyed the avifauna of Alto do Palácio, Serra do Cipó National Park, Minas Gerais state, Brazil. The park lies in the southern Espinhaço range, a significant biogeographical barrier that separates the forest areas of the Atlantic Forest on its eastern slope and the savanna-like vegetation of the Cerrado to its western slope. Representative habitats include open grasslands, with patches of rocky outcrops and woodlands. We recorded 151 species between 2007 and 2010. Most species occurred in woodlands, with the minority in rocky outcrops, eleven species are of conservation concern, nineteen are endemic to the Atlantic Forest, three to Cerrado, and four to the southeastern Brazilian mountaintops, two of which are restricted to campos rupestres of the Espinhaço range. Our results corroborate that the campos rupestres of the Espinhaço range are not only associated with the Cerrado biome, but harbor species associated with both surrounding biomes (Cerrado and Atlantic Forest) and to the mountaintops of southeastern Brazil, supporting the uniqueness of this vegetation type.

“…Studies on local faunas have demonstrated that orchid bee species richness is highest at Tropical Evergreen Forests, situated in lower latitudes. Also, there is a tendency towards the changing of the bee fauna as altitudes go higher (e. g. Silveira & Cure 1993). Thus, the results presented here suggest that forest fragments in large urban areas may effectively support viable populations of orchid bees and the conservation status of these areas should be considered with great care.…”

Neotropical Entomology 36(2): 186-191 (2007) ABSTRACT -Male orchid bees were collected by chemical baiting in four forest fragments in parks of the city of Belo Horizonte, Minas Gerais, southeastern Brazil. One thousand three hundred and compared through correlation tests. The data suggest that abundance of orchid bees tend to increase with fragment size, although no correlation between species richness and fragment size was obtained. The results presented herein suggest that forest fragments in a large city may be of importance concerning conservation of orchid-bee faunas.

“…Stehmann (1999) sugeriu a existência de uma rota migratória de ancestrais de Calibrachoa através do pampa, atingindo o planalto das araucárias e algumas serras do sudeste do Brasil. Silveira & Cure (1993), estudando o padrão de distribuição geográfica da fauna apícola nas regiões de altitude do sudeste do Brasil, encontraram um grupo de espécies ocorrendo nas montanhas do sudeste do Brasil e em latitudes superiores a 24°S no sul do Brasil e sugeriram que tais espécies poderiam ser remanescente de uma fauna associada com a vegetação subtropical e temperada que avançou para o norte nos períodos frios. Hexantheda missionica apresenta esse padrão de distribuição geográfica e as populações disjuntas de H. missionica encontradas nas regiões de altitude da região sudeste do Brasil, como a área do quadrilátero ferrífero de Minas Gerais, podem ser interpretadas como remanescentes de populações que permaneceram confinadas no topo das montanhas quando o clima tornou-se mais quente.…”

-(Reproductive biology of Calibrachoa elegans (Miers) Stehmann & Semir (Solanaceae)). Calibrachoa elegans is an endemic annual species from the "canga" region in the iron quadrangle, Minas Gerais, Brazil. The study of its reproductive biology involved cross-pollination experiments, self-incompatibility tests and observations of the pollination process. Results of manual pollination experiments showed that the studied population is allogamous. Interruption of pollen tube growth in the style of self-pollinated flowers confirmed the occurrence of self-incompatibility reactions. Pollination is effected only by females of Hexantheda missionica (Colletinae, Apoideae), which show high fidelity to flowers of C. elegans; males use the flowers as a nectar source, as stops between flights when searching for females, and as shelter during the night. They prepare the shelter by cutting and removing anthers and style. The populations of Hexantheda missionica found in Minas Gerais are the first records of this species for southeastern Brazil and probably represent remnants that reached this region during the past, but are now disjunct and isolated from those in southern Brazil.RESUMO -(Biologia reprodutiva de Calibrachoa elegans (Miers) Stehmann & Semir (Solanaceae)). Calibrachoa elegans é uma espécie anual, endêmica da região da canga do quadrilátero ferrífero de Minas Gerais, Brasil. O estudo da sua biologia reprodutiva envolveu experimentos de cruzamentos, teste do sistema de auto-incompatibilidade e observação do processo de polinização. Os experimentos realizados através de polinizações manuais indicam que a população estudada é preferencialmente alógama. A interrupção do crescimento do tubo polínico no estilete das flores autopolinizadas, verificada através da microscopia de fluorescência, confirmou a ocorrência de reação de auto-incompatibilidade. A polinização é realizada apenas pelas fêmeas de Hexantheda missionica (Colletinae, Apoideae), uma abelha com alta fidelidade de visita às flores de C. elegans. Os machos desta espécie utilizam as flores como fonte de néctar, como local para pouso entre os vôos de patrulhamento a procura de fêmeas para acasalamento e como abrigo noturno. Para se acomodarem na flor, geralmente cortam e removem os estames e o estilete. As populações de Hexantheda missionica encontradas em Minas Gerais são o primeiro registro da espécie para a região sudeste do Brasil e, provavelmente, representam remanescentes que chegaram a esta região no passado e que agora se encontram disjuntas e isoladas das populações da região sul do Brasil.
