The present study provides a comprehensive review of cytogenetic data on Meliponini and
their chromosomal evolution. The compiled data show that only 104 species of stingless …

Phylogeographic studies have sought to explain the genetic imprints of historical climatic
changes and geographic barriers within the Brazilian Atlantic Forest (AF) biota, and …

Ribosomal DNA (rDNA) loci are essential for cellular metabolism due to their participation in
ribosome biogenesis. Although these genes have been widely cytogenetically mapped, the …

The characterization of karyotypes is an important aspect in understanding the structure and
evolution of genomes. Polybia is a genus of social wasps of the family Vespidae. This genus …

The genus Melipona is subdivided into four subgenera based on morphological
characteristics, and two groups based on cytogenetic patterns. The cytogenetic information …

It is thought that two evolutionary mechanisms gave rise to chromosomal variation in bees:
the first one points to polyploidy as the main cause of chromosomal evolution, while the …

Chromosomal regions enriched in repetitive DNA sequences have a predisposition to
instability, resulting in a propensity to undergo structural rearrangements. Hence, the rRNA …

Mitochondrial (mtDNA) genes have served as widely utilised genetic loci for phylogenetic
and phylogeographic studies of animals. However, the phylogenetic performance of many …

Cytogenetic molecular studies involving hymenopterans have improved our knowledge
about the composition, organization and evolution of the genomes of these insects …

Recent phylogenetic and molecular data are changing our knowledge about the relations
between species and evolutionary processes resulting in the chromosome variation …
