Vessel traffic disrupts the foraging behaviour of southern resident killer whales Orcinus orca.

2009
Open Access Peer Reviewed Publication

Endangered Species Research

Lusseau, D., Bain, D. E., Williams, R. and Smith, J. C.

Vessel traffic may have contributed to southern resident killer whales Orcinus orca becoming endangered. To determine the importance of this threat, we measured the behavior of...
