Southern elephant seal vagrants in Ecuador: a symptom of La Niña events? ...
Background: Extralimital observations of pinnipeds are important to understand the effects of changing climates on our oceans and the distribution of these species. The southern elephant seal (Mirounga leonina) is a known vagrant species that moves over long distances. We report three new records of...
