The Amazon basin is home to a rich diversity of fishes, among which Loricariidae stand out for their adaptations to lotic environments and their ecological importance. The genus Spectracanthicus, endemic to the Brazilian Shield, presents high morphological and ecological diversity, but its phylogenetic relationships and diversification patterns are still poorly understood.
My study aims to reconstruct the phylogeny of Spectracanthicus species using medium-coverage genome data, to infer the phylogenetic relationships between species and estimate divergence times.
This study aims to investigate the population structure of fish species threatened with extinction due to the loss of lotic habitats (rapids) due to the implementation of hydroelectric dams in rivers of the Amazon basin.
By analyzing the genetic structure of these species, we hope to contribute to the understanding of the evolutionary processes that shaped fish diversity in the Amazon and to support conservation strategies.
