Uncertainties associated with trophic discrimination factor and body size complicate calculation of δ15N‐derived trophic positions in Arapaima sp.
Stable isotope ratios of nitrogen (δ15N) have been used to estimate trophic position (TP) of organisms due to the predictable enrichment of nitrogen‐15 in consumer tissues relative to their diet. We explored estimates of trophic position using liver and muscle δ15N and stomach content analysis in a...
