Arctic seals as tracers of environmental and ecological change

Limnology and Oceanography Letters, 2021
Knowledge of species trophic position (TP) is an essential component of ecosystem management. Determining TP from stable nitrogen isotopes (δ15N) in predators requires understanding how these tracers vary across environments and how they relate to ...
