Should I stay or should I go? Modelling year‐round habitat suitability and drivers of residency for fin whales in the California Current
Abstract Aim Understanding the spatial ecology of endangered species is crucial to predicting habitat use at scales relevant to conservation and management. Here, we aim to model the influence of biophysical conditions on habitat suitability for endangered fin whales Balaenoptera physalus , with a v...
