Stomach flushing vs. fecal analysis: The example of Phrynops rufipes (Testudines: Chelidae)
The following is a study of the trophic niche of Phrynops rufipes revealed by an investigation of stomach flushing and fecal samplings. We successfully stomach flushed all 31 adult turtles captured and collected feces from ten of the flushed turtles. Our results show that only an integrated approach...
