Evidence of a main role of chromosomal fusion in the occurrence of gradual decrease of chromosome number in Epiponini during its chromosomal evolutionary history is found and it is suggested that chromosomal segments with high GC content must have had a key role in the karyotype diversification of these wasps.

The Bayesian divergence dating analysis revealed recent Plio-Pleistocene diversification in Synoeca, and the biogeographical analysis suggested an Amazonian origin of SyNoeca, with three main dispersal events subsequently occurring during the Plio, Pleistocene.
Record of Parasitoids in nests of social wasps (Hymenoptera: Vespidae: Polistinae)
The aim of this study was to record the parasitoid species found in social wasps nests sampled in different localities in Brazil and investigate the existence of preferential host-parasite…

An intraspecific numerical-structural chromosome variation in the swarm-founding wasp Metapolybia decorata from the Brazilian Atlantic Rainforest is reported indicating that the species is undergoing a continued process of karyotype evolution leading to fused chromosome stabilization by elimination of inactive centromeric sequences.

The present study uses an integrative approach to reconstruct the evolutionary history of Partamona rustica, an endemic stingless bee from dry forest diagonal in Brazil, in a spatial-temporal framework and indicated that the inferences both from the genetic data analyses and from the spatial distribution modelling are compatible with historical demographic stability.
Predicting priority areas for conservation from historical climate modelling: stingless bees from Atlantic Forest hotspot as a case study
AbstractAssuming that genetically diverse populations of bees are less likely to suffer the harmful effects of inbreeding and better able to avoid an extinction vortex related to the sex…

The present findings underscore the importance of concentrating efforts on the conservation of dry areas and the endemic species that inhabit these forests, including Partamona rustica, endemic to these environments and its biology is poorly known.
Genetic and paleomodelling evidence of the population expansion of the cattle egret Bubulcus ibis in Africa during the climatic oscillations of the Late Pleistocene
The hypothesis that the species range of the cattle egret expanded during arid periods and contracted during wet periods is supported, which corroborates the expansion during the LGM, and a more restricted potential distribution during the Last Interglacial (LIG) period.

The karyotype of Trypoxylon rugifrons F. Smith, 1873 is reported which has the lowest chromosome number in the genus and other characteristics of the likely ancestral trypoxylon karyotypes.
