Body size is more important than diet in determining stable-isotope estimates of trophic position in crocodilians
The trophic position of a top predator, synonymous with food-chain length, is one of the most fundamental attributes of ecosystems. Stable isotope ratios of nitrogen (δ(15)N) have been used to estimate trophic position of organisms due to the predictable enrichment of (15)N in consumer tissues relat...
