Historical biogeography and population genetic structure of the giant gilded catfish (Brachyplatystoma rousseauxii): expanding Humboldtian connectivity routes between the Orinoco and Amazon River basins
Understanding the evolutionary history of species within a geographic context is key to historical biogeography, as it reveals how geological and climatic changes shaped biodiversity. This is especially important in ecologically significant regions like the Amazon and Orinoco basins. Together, they host the world's greatest freshwater fish diversity ([~]3,500 species), sharing a common but not…
