Understanding how air-breathing diving animals respond to resource quality is foundational to studying their foraging ecology. We quantified relationships between southern elephant seal dive effort an
With a population of about 2 million pairs macaroni penguins are the most abundant penguin in the HIMI region. These birds feed on mesopelagic fish and, to a lesser extent, mackerel icefish. Despite t
Social behaviour may enable organisms to occupy ecological niches that would otherwise be unavailable to them. Here we test this major evolutionary principle by demonstrating self-organizing social be
To date, the study of collective behaviour has mainly focused on intraspecific situations: the collective decision-making of mixed-species groups involving interspecific aggregation-segregation has re
