Our research group has been working with native bees, or those with a wide geographic range in Brazil, for more than 25 years. We have generated solid data on the population genetics and phylogeography of several species of Meliponini and Bombini. Over the last 10 years we have been using genomic and bioinformatics approaches with the aim of investigating questions about bee behavior in a…
Elaine Françoso has the prestigious Skodowska-Curie fellowship and develops her research at Royal Holloway, University of London, UK. Her current project is ambitious and aims investigate the evolution of the interaction between mitochondrial and nuclear genomes, with emphasis on numts (nuclear copies of mitochondrial genes that migrated to nucleus) and heteroplasmy (multiple copies of mi…
Bees comprise a highly speciose group. It has been recognized 20,452 species around the World. Their role as pollinators of native and commercial plants is unquestionable benefiting human beings and the environment by their ecosystem services free of charge. Bees have been studied for centuries because aside their ecological features they present the intriguing behavior of eusociality. Th…
Pollinators play unquestionable ecological services important for native flora maintenance and also increasing crops productivity. During the last decades several reports have been warning for the pollinators decline all over the world. The genus Bombus, an important pollinator in temperate climate, has gained attention for the high extinction of species. Among those, here in South Americ…

The bees of the Meliponini tribe, popularly known as stingless bees, hold great ecological and cultural significance in tropical regions. This is a taxonomically diverse group that exhibits a wide range of behaviors, including the use of different substrates and nest structures, as well as distinct strategies for defense and resource collection. Interestingly, some species, such as Lestri…
Presenting a wide range of behaviors, with different levels of social organization, bees have kleptoparasitism present in approximately 13% of all 20,700 species already described. However, there is still a large knowledge gap involving various aspects of kleptoparasitic bees. In turn, approaches such as transcriptomics and genomics have been playing a key role in filling these gaps. It i…
Stingless bees (Apidae, Meliponini) are among the most common and abundant pollinators in tropical regions, especially in the neotropics. This group has a wide taxonomic diversity, with more than 500 described species, 243 of which are found in Brazil. Some species have adaptations that allow them to survive adverse environmental conditions. Species from the subtropical region of Brazil, …

Population genetics and phyologeographic studies enable to unveil population dynamics, species evolutionary history, detection of cryptic species and also these information may be very useful to subsidize conservation actions. This project aim at performing a phylogeographic survey for two species: Tetragonisca angustula and Xylocopa frontalis. Both species have a wide geographic range in…

Many species exhibit seasonal adaptive behaviors that are associated with adverse environmental conditions. One key strategy employed is dormancy, which is characterized by arrest of development or activities, frequently accompanied by metabolic suppression. The stingless bees, the highly eusocial group Meliponini, from the subtropical region of Brazil, such as Plebeia remota and Melipona…
The chemosensory-related genes (CRGs) encompass well-documented gene families and playa crucial role in insects ability to recognize stimuli, and are implied in many biologicalprocesses. Bees are valuable models for the study of this system, given their diverse habitats,lifestyles, social organizations, complex behaviors, including various parasitism displays. Theadvances in sequencing an…
Evolution of cooperative and altruistic behaviours have been important topics in evolutionary biology for years. The fire ant Solenopsis invicta is a remarkable model for such studies because in this species two distinct forms of social organization co-exist. According to the allele frequency of the pheromone-binding gene Gp-9, it is possible to predict the colony queen number. In homozyg…
