Rapid sampling of social wasps (Hymenoptera: Vespidae) in an ecotone zone between the Atlantic Forest and Cerrado adjacent to a mining area
Abstract
There are few studies on the richness of social wasps in ecotones, particularly in mining regions. These transitional environments exhibit specific geophysical conditions, host species from both biomes, and can act as barriers to evolutionary processes and gene flow. In view of this, this study aimed to document the occurrence of social wasps by a rapid sampling method in a transition region between the Atlantic Forest and Cerrado in the vicinity of a mining area in Itatiaiuçu, Minas Gerais, Brazil. The sampling effort was 24 h, distributed over three field days in December 2022. A total of 18 species were sampled. One noteworthy record is that of Parachartergus smithii (de Saussure, 1854), a rare species in the state, previously documented in an ecotone region between the Caatinga and Cerrado. These findings demonstrate the importance of ecotone systems in supporting the diversity of social wasps.
