Trans-Amazonian natal homing in giant catfish — bt.duponchelle.2016 • MFishBTdat

The authors measured 87Sr/86Sr ratios in transects along transverse sections of Brachyplatystoma rousseauxii otoliths, and compared these observed profiles with those expected from different scenarios of space utilization and migration.
