Traditional ecological research has focused on taxonomic units to better understand the role
of organisms in marine ecosystems. This approach has significantly contributed to our …

The first comprehensive review on North Atlantic killer whales Orcinus orca was published in
1988. Since then, a significant increase in published studies has substantially improved our …

Quantifying the diet composition of apex marine predators such as killer whales (Orcinus
orca) is critical to assessing their food web impacts. Yet, with few exceptions, the feeding …

Ecological diversity has been reported for killer whales (Orcinus orca) throughout the North
Atlantic but patterns of prey specialization have remained poorly understood. We quantify …

Killer whales (Orcinus orca) occur seasonally in the eastern Canadian Arctic (ECA), where
their range expansion associated with declining sea ice have raised questions about the …

Non-social factors can influence animal social structure. In killer whales (Orcinus orca), fish-
versus mammal-eating ecological differences are regarded as key ecological drivers of their …

Sightings of killer whales (Orcinus orca) in Greenland have increased in recent years,
coincident with sea ice loss. These killer whales are likely from fish-feeding North Atlantic …

Interindividual variation in prey specialization is an essential yet overlooked aspect of
wildlife feeding ecology, especially as it relates to intrapopulation variation in exposure to …

Fisheries may generate new feeding opportunities for marine predators, which switch
foraging behaviour to depredation when they feed on fish directly from fishing gear …

Killer whales have a cosmopolitan distribution and as a species are generalists, feeding on
a variety of prey. However, local populations tend to specialise on specific prey types. In …
