The confounding effects of source isotopic heterogeneity on consumer–diet and tissue–tissue stable isotope relationships
Stable isotope analysis of consumer tissues document patterns of resource use because
data are linearly related to isotope compositions of their source (s)(ie, food, water, etc.) …

Using δ13C stable isotopes to quantify individual-level diet variation
Individual-level diet variation can be easily quantified by gut-content analysis. However,
because gut contents are a 'snapshot'of individuals' feeding habits, such cross-sectional …
