Estrutura e composição da assembleia de abelhas Euglossini em vegetação não florestal ao longo de um gradiente altitudinal

Abstract

The assembly of Euglossini bees in non-forest vegetation is still little known. Therefore, we evaluated the factors that affect the distribution of this group along the gradient of elevation of cerrado sensu stricto to rupestrian grasslands. Abundance reduced with altitude, unlike the richness and diversity of species. The composition varied along the gradient, due to the substitution of individuals of some species by individuals of others. The patterns of altitude responses were similar between dry and rainy seasons, despite the difference in composition. There was no influence of environmental variables on bee distribution. We also emphasize the importance of the conservation of the adjacent mesic environments in the conservation of Euglossini and maintenance of its services in savannas.
