Robustly quantifying dietary resource use and trophic position using stable isotopes
requires accurate trophic discrimination factors (TDF; Δ13C and Δ15N for carbon and …

The development of the isotopic niche, an n-dimensional hypervolume (with n being the
number of isotopes) occupied by a population in delta space, has revolutionized the study of …

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 …

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 …

The contribution of non-indigenous species to the transfer of contaminants in invaded food
webs represents an active research area. Here we measured trace metals and CN stable …

Stable isotope analysis (SIA) is widely used to assess animal diet and movements, requiring
accurate estimates of trophic discrimination factors (TDFs). Since TDFs are only available for …

Understanding the structure and functioning of marine ecosystems has become a critical
issue to assess the potential short-and long-term effects of natural and anthropogenic …

Species of the family Sternoptychidae (hatchetfishes) occur worldwide and play critical roles
by sequestering carbon, recycling nutrients, and acting as a key trophic link between …

The measurement of naturally occurring stable isotope ratios of the light elements (C, N, H,
O, S) in animal tissues and associated organic and inorganic fractions of associated …

Trophic ecology is the study of feeding interactions and food acquisition by organisms. It
includes the causes and consequences of those behaviours at all levels of biological …
