Stingless bee (Apidae, Meliponini) guilds occurring in the immediate edges of forest fragments of the Baturité Massif, State of Ceará, Brazil

Abstract This study investigated the occurrence of individuals of stingless bees attracted by the trophic resources existing in four edge areas of forest fragments located in the Baturité Massif, State of Ceará. In this sense, the study evaluated the species richness in the areas; the absolute abundance of species; the similarity of species between edges; and the affinity of bees for the same plant species. The sampling of bees compiled a total of 20 species distributed in 12 genera. Seven species stood out for abundance and two (Trigona spinipes and Trigona fulviventris) showed dominance. The results also showed that the fragments present a similar stingless bee fauna and the affinity of the bee species for the same plant species revealed the formation of five distinct bee groups in foraging preferences involving 15 (75%) out of the 20 species of bees studied.
