Effective conservation of species and ecosystems requires the understanding of important
ecological traits, such as dietary habits, food webs, and trophic niches. In diet studies, the …

Human evolution has clearly been shaped by gene–culture interactions, and there is
growing evidence that similar processes also act on populations of non-human animals …

Killer whales (Orcinus orca) are among the most highly polychlorinated biphenyl (PCB)–
contaminated mammals in the world, raising concern about the health consequences of …

Killer whales (Orcinus orca) are currently recognized as a single ecologically and
