Stable isotope analysis (SIA) and gut contents analysis (GCA) are commonly used in food web studies, but few studies analyse these data in concert. We used SIA (Ol5N) and GCA (% composition) to identify diets and trophic position (TP) of six stream fishes and to compare IP estimates between methods. Ordination analysis of gut contents identified two primary trophic groups, omnivores and predators. Significant differences in TPocA and TPSIA were similar in direction among-specics and among… CONTINUE READING
