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 …

Ecological applications of stable isotope data require knowledge on the isotopic turnover
rate of tissues, usually described as the isotopic half-life in days (T 0.5) or the change in …

An important metric of environmental health is food web structure because it reflects species
richness, natural history diversity, and resource availability. While bulk‐tissue stable isotope …

Four diets were formulated to evaluate the partial to total substitution of fishmeal with poultry
by‐product meal (PBM)(0, 33, 67 and 100 PBM) in diets for totoaba juveniles (Totoaba …

Tissue stable isotopes can be used for dietary reconstruction provided that the factors
influencing turnover rates and trophic discrimination factors (TDFs) between consumer …

The extensive utilization of both legacy and novel brominated flame retardants (BFRs) leads
to high environmental concentrations, which would be bioaccumulated by organisms and …

Background We used stable isotope profiling (15 N and 13 C) to obtain indicator phenotypes
for feed efficiency in aquaculture. Our objectives were to (1) examine whether atom percent …

Nitrogen is a key nutrient for fish and vegetable productions in aquaponic systems.
However, the fate of nitrogen in aquaponic systems has not been fully understood, leading …

Stable isotope analysis was conducted to investigate stable isotope ratios of carbon (δ 13 C)
and nitrogen (δ 15 N), diet-tissue discrimination factors of carbon (Δ 13 C) and nitrogen (Δ …

Isotopic ratios of nitrogen are often used in food‐web studies to determine trophic position
(including food chain length) and food sources, with greater ratios of 15N/14N (δ15N) …
