Ecological niche segregation among five toothed whale species off the NW Iberian Peninsula using ecological tracers as multi-approachs
This study aims to assess niche segregation among the five main toothed whales that frequent the NW Iberian Peninsula waters: the common dolphin, the harbour porpoise, the bottlenose dolphin, the striped dolphin and the long-finned pilot whale. We used cadmium (Cd) and stable isotope ratios (δ13C an...
