Did signals from seabirds indicate changes in capelin biology during the 1990s? Comment on Davoren & Montevecchi (2003)
In a recent paper, Davoren & Montevecchi (2003a) reported on the interactions between a seabird, the common murre Uria aalge, and one of its prey, the capelin Mallotus villosus, a forage fish in boreo-arctic waters throughout the northern hemisphere. The authors described common murres as capeli...
