Meta‐analysis and critical review of trophic discrimination factors (Δ13C and Δ15N): Importance of tissue, trophic level and diet source
Robustly quantifying dietary resource use and trophic position using stable isotopes
requires accurate trophic discrimination factors (TDF; Δ13C and Δ15N for carbon and …

Current methods and future directions in avian diet analysis
Identifying the composition of avian diets is a critical step in characterizing the roles of birds
within ecosystems. However, because birds are a diverse taxonomic group with equally …

Reevaluating trophic discrimination factors (Δδ13C and Δδ15N) for diet reconstruction
Stable isotope analysis is increasingly being used to assess diet and trophic positions of
animals. Such assessments require estimates of trophic discrimination factors (TDFs)—offset …

Gaining insight into the assimilated diet of small bear populations by stable isotope analysis
Apennine brown bears (Ursus arctos marsicanus) survive in an isolated and critically
endangered population, and their food habits have been studied using traditional scat …

The effect of a harmful algal bloom (Karenia selliformis) on the benthic invertebrate community and the sea otter (Enhydra lutris) diet in eastern Hokkaido
In recent decades, the locally extinct sea otter (Enhydra lutris lutris) has been recolonizing
the coast of eastern Hokkaido. Their diet includes benthic invertebrates such as bivalves …

Sexual segregation in the foraging distribution, behaviour, and trophic niche of the endemic Boyd's shearwater (Puffinus lherminieri boydi)
Studies on sex-specific segregation in foraging behaviour and trophic niche have been
focussed on large and dimorphic seabirds, with less information on small monomorphic …
