Análise citogenética de Callimedusa tomopterna (Cope, 1868) (Anura, Phyllomedusinae) em diferentes biorregiões da Amazônia Central

A cytogenetic analysis of the leaf frog Callimedusa tomopterna across Central Amazon bioregions reveals distinct chromosomal structuring patterns influenced by major rivers, suggesting cryptic diversity within the species. The study found a conserved karyotype (2n=26) but identified significant north-south differences in nucleolar organizer region (NOR) location on chromosome pair 7, supported by molecular techniques like FISH and fluorochrome staining. These patterns imply structural rearrangements, such as pericentric inversions, potentially driven by geographic barriers like the Amazon River. The findings hint that C. tomopterna may represent a species complex, with implications for evolutionary and taxonomic studies in the region.
