Assessing the trophic position of two sharks from the open waters of the southeastern Pacific Ocean

Stable isotope analyses for shortfin mako (Isums oxyrinchus) and blue sharks (Prionace glauca) were conducted to assess their trophic position in two periods of time (before 1980 and after 2000) in the Southeastern Pacific waters (SEP). Both sharks showed that their trophic position decreased over t...
