Density-dependent migratory waves in the marine pelagic ecosystem
Fauchald, Per; Mauritzen, Mette; Gjøsæter, Harald (Journal article; Peer reviewed, 2006-11)The migration of large aggregations of animals that sweep through the landscape is a phenomenon with large consequences in many ecosystems. It has been suggested that such migrations are mediated by resource depletion. ... -
