Abstract: Abstract:The composition of local orchid-bee faunas (Hymenoptera, Apidae, Euglossina) in open-vegetation domains is poorly known, making the ecology and biogeography of the group difficult to understand. The aim of this work was to answer the following questions: i) Is the orchid-bee fauna composition, species richness and abundance in the cerrado (Brazilian savanna) sensu stricto similar to that of riparian forests immersed in that domain? ii) Do species from neighboring forest domains use riparian forests as… Show more

“…The results of the present study, plus those obtained by Viotti et al (2013), Justino and Augusto (2012) Faria and Silveira (2011), Alvarenga et al 2007 andFaria (2004), in other areas of savanna (Cerrado) in Minas Gerais state, revealed a total of 16 orchid bee species for this region. So far there is no list for the orchid bee fauna in the Cerrado of Minas Gerais.…”

“…Despite Faria and Silveira (2011) explain the low richness and abundance of orchid bees in Cerrado areas, as a result from relative food scarcity, which, in turn, would be a consequence of a combination of low soil fertility and relatively low seasonal precipitation, our results are going in an opposite way. The Cerrado is a very rich floristic region with many different habitat types (Joly et al, 1999) and that habitat heterogeneity may provide the necessary resources for orchid bee species.…”

“…Comparado a outros estudos (CARVALHO et al, 2006;ALVARENGA et al, 2007;FARIA;SILVEIRA, 2011), que fizeram amostragens, também no domínio de Cerrado e por um período mais longo, este estudo, em apenas quatro meses de coleta na estação chuvosa, obteve registro superior tanto em riqueza quanto em abundância de abelhas Euglossina. Essa condição indica que a extensão do plantio de eucaliptos e outros cultivos nesses locais ainda não foram suficientes para extinguir a grande diversidade das espécies de abelhas da região amostrada.…”
